o have the luxury of practicing in the area where I grew up is perhaps why community outreach is so important to me. Giving back has always been a part of the culture of this practice — a tradition that dates back to its founding in 1958. I joined the practice in 1988 and became a partner shortly thereafter. I felt it was important to continue the custom of community philanthropy. We’ve participated in some of the usual things that small businesses in small towns do, supporting local little league teams and school bands. Our entire office team walks for fundraisers, holds special toy drives for the children in local hospitals, and collects food donations to help local soup kitchens and pet supplies for the Humane Society. Most people have heard how teachers use their own money to subsidize their students — for supplies and even for books — so we dedicate a portion of our marketing budget to school supplies. Some schools in Southeastern Connecticut don’t need help while others are quite disadvantaged. Because we’re dialed into the neighborhoods we serve, we understand where the need is greatest. One of our marketing activities even took a turn toward “paying it forward.” Making presentations on dental health and orthodontics in area classrooms prompted conversations with teachers and nurses about orthodontic emergencies, so we now deliver orthodontic emergency kits to all the local schools. School nurses visit our office to learn how to manage emergency care. Small things such as how to stabilize a bracket that has become loose or how to use wax to soothe an irritation keep kids in school and save parents an unscheduled visit to our office. Smile for a Lifetime Foundation (S4L) offers an incredible opportunity for us to give back to the community, and my practice partner, Dr. Gregory Hack, and I are quite involved in its endeavors. A bank president, a local lawyer, a pediatrician, pediatric dentists, an oral surgeon, and educators serve on the board of our local S4L chapter. We market directly to teachers, dentists, and school guidance counselors, looking for those children and adolescents who could most benefit from orthodontic care but whose family budgets could never cover the cost. The direst needs are disfiguring malocclusions. Through S4L, we are committed to offering six “orthodontic scholarships” to patients in need annually. From the applications received, the board grants these scholarships for treatment. The charter of the S4L Foundation was established to deliver complimentary orthodontic treatment, but our program covers the full gamut of dental care in those patients who require interdisciplinary care. We have partnered with general dentists and dental specialists in our community to provide pro bono dental care for our S4L patients whenever indicated. A network of clinicians offers a number of services such as extractions through an oral surgeon, periodontal surgery, and dental implant placement from a periodontist. One patient who recently required implant-supported crowns to replace both of his congenitally absent maxillary lateral incisors had dental implants placed by a periodontist and crowns placed by a prosthodontist with both dentists doing the work gratis. We do not receive any financial support from the national office of S4L. Seeing a young person‘s self-confidence blossom as a result of a natural smile and healthy bite is heartwarming, and the stories the kids tell about how different they feel about themselves and how differently they’re treated at school is what the effort is all about. Ormco™ has supported S4L with fundraisers at their annual Forum and through sizeable contributions. Being Damon™ System users, we appreciate their backing as they donate all our orthodontic clinical supplies to treat our S4L patients. We provide all of our patients with patient-centered, problem-oriented diagnosis and treatment planning. We utilize Damon™ System appliances, SureSmile®, and Invisalign® treatment solutions, which enable our practice to provide high-quality results predictably and consistently. Using orthodontic therapy that respects patients’ facial features, delicate soft tissues, and keeps them as comfortable as possible — there’s hardly a better way for an orthodontist to give to the community. Doctors interested in learning more about S4L and how to become a S4L provider in their community may visit www.s4l.org. Dr. Jim O’Leary

Incognito™ Clear Precision Tray Less Deviation from Correct Bracket Position The precision of the Incognito™ Appliance System relies on the brackets being placed in the correct spot on the tooth. 3M Unitek has developed a proprietary way to build the indirect bonding tray using the same digital data created for designing the brackets. The result is more accurate placement of the brackets. Graphs illustrate the deviations of bracket positioning using the stated method as compared to the design data. The Incognito™ Clear Precision Tray method is significantly more accurate.

Dr. Sonia Palleck Staying current and always learning
erving the greater London and Woodstock, Ontario, areas, Dr. Palleck runs an esteemed practice that regards its patients as the number one priority day in and day out and recognizes that technology is the future of the craft.
What can you tell us about your background, and why you decided to become an orthodontist? I have four siblings, each of whom had orthodontic treatment as a child, just as I did. We were continually in and out of an orthodontic office, and I guess you could say that’s where I drew my inspiration to explore the profession. When I was 17 years old, I went to my orthodontist for my final retainer check, which happened to coincide with an aptitude test I had just taken in high school. I scored highest for being a dentist, and just like that, everything clicked! I went on to pursue dentistry at the University of Western Ontario and then completed 3 years of orthodontic specialty training at the same university. To come full circle, I now teach graduate orthodontic courses at the university, instructing graduate students about how to become orthodontists using Insignia™ (Ormco Corporation). 6 Orthodontic practice
How long have you been practicing, and what appliances do you use? I have not only had orthodontic treatment, I have experienced almost every procedure and appliance you could have in your mouth! I have been retreated twice to deal with problems that developed as a direct result of my earlier treatment, which included serial extractions, headgear, and jaw surgeries. This has impacted my philosophy greatly. My role as an orthodontist is to get the teeth to fit together — the nice side effect is that they are straight! I want to do this in as few visits as possible with as little pain as possible and make it as affordable as possible. I have been practicing for 15 years and use a variety of tools, most notably Ormco’s Insignia™ Advanced Smile Design™, which offers patients customized treatment planning and appliances tailored to their specific needs. In fact, my practice was an early adopter of Insignia, and we are currently the largest provider in Canada. We use the Lythos™ scanner to start designing the appliances online. No more impressions! We are Elite
providers of Invisalign® (Align Technology, Inc.), and we couple all of our treatment, whether it’s aligners or custom braces, with AcceleDent® (OrthoAccel Technologies, Inc.), a micropulse technology that soothes the teeth and speeds bone remodeling. I am definitely an early adopter when it comes to technology. If there’s a new, advanced product hitting the market, we either know what it is or have already placed our order for it.
What is the most satisfying aspect of your practice? The most satisfying aspect of my practice is having the opportunity to dramatically and positively impact people’s lives. It’s fulfilling to see a patient’s life change as a result of the work that my staff and I love doing so much. When treatment is finished, Volume 5 Number 6

puzzle. If you keep the patient in mind with every decision you make and goal you set, you will build and maintain a successful practice. At Palleck Orthodontics, we aim to serve the patient as best as we possibly can.
What is unique about your practice?
There are three key pieces of advice that I would give to budding orthodontists. • Focus on your results. It’s important to remember that, ultimately, your patients’ results will determine your reputation in the marketplace. Giving your clients what they want — a beautiful, healthy smile — should be the primary focus. • Welcome technology with open arms. You never want to be behind the times. To remain relevant, you have to utilize the incredibly advanced orthodontic solutions that are continually made available to you. These tools have the capability to transform your practice and set you apart as a premium, patient-focused orthodontist.
My staff is exceptional! My colleagues often complain that they have to deal with staff issues. I am fortunate not to have those problems. We are like one big, happy, energetic family. I have 10 amazing women who collectively have 104 years of orthodontic experience! They are highly motivated and are continually updating and upgrading their skills to meet the challenges that evolving systems have on a busy practice. We are expanding into the adult market with more than 30% of our practice now over 20 years of age. I believe this is because we can treat most patients in 12 months or fewer with our approach.
What is the future of orthodontics?
What advice would you give to budding orthodontists?
• Never stop learning. Mastering orthodontics is a lifelong learning process. Dedicate yourself to staying up-to-date on the latest technologies, techniques, and developments. This is what will keep you ahead of the curve.
When you’re not behind the chair, where are you? I enjoy being active outside — I love biking, running, and swimming. In my leisure time, I also like to read or play golf with my husband. Of course, my young daughter keeps me busy as well! She signed us up for Zumba! Spending time with family and friends is very important to me.
If you hadn’t become an orthodontist, what would your career have been? I would probably be a writer or a professor. More specifically, I think I would really have enjoyed being an English professor. I love using my imagination. In a way, with orthodontics I get to flex my creative muscle every day. OP
I’m a strong believer that the future of orthodontics lies in technology. The profession as a whole is on the upswing, especially considering the influx of digital technologies. Practice tools such as Insignia are revolutionizing the market. Instead of taking a onesize-fits-all approach to patient care, with Insignia, practitioners are able to create exactly what they need — something that has never been available before. The best part about introducing new technologies into my practice is that patients respond, and they respond well.
What are your top tips for maintaining a successful practice? Always, always remember that the patient is the most important piece of the

Volume 5 Number 6
Boyd Martin, DMD, MS Architect of the smile What can you tell us about your background? I grew up in Newport Beach, California, and received my undergraduate degree from University of California (UC) San Diego. I attended Tufts University School of Dental Medicine in Boston for my dental degree. Following an Advanced Education in General Dentistry (AEGD) at the University of Southern California School of Dentistry (USC), I returned to the East Coast for my orthodontic residency at Case Western Reserve University School of Dental Medicine in Cleveland, Ohio. At the time, Case Western was on the forefront of the development of the cephalogram, and each class contained only four people. The program was a 30-month certificate program combined with a Master’s degree. My Master’s thesis used cone beam (CBCT) technology to look at root morphology in three dimensions. I graduated residency in December 2007, returned to Southern California to get married, and have been at a practice supported by Pacific Dental Services® (PDS) since July 2008. In addition to clinical practice, I was fortunate to teach Phase I Orthodontics to USC Pediatric Dental Residents for 3 years at an offsite clinic in Garden Grove, California. In September 2015, I am entering an Executive Master’s Program in Public Health at the University of California, Los Angles (UCLA) Fielding School of Public Health.
When did you become a specialist and why? I started residency in July 2005 following my AEGD. I was always drawn to the closer patient interaction that orthodontics offered and was inspired by my own orthodontics at age 17-19 to become an orthodontist. I loved continuing the learning process and wanted to focus on a more specific aspect of dentistry. 10 Orthodontic practice
Is your practice limited solely to orthodontics, or do you practice other types of dentistry? My practice is solely limited to orthodontics, but I practice in a Dental Support Organization (DSO)-environment working for a PDSsupported owner-doctor and with other specialists, including an oral surgeon, pediatric dentist, endodontist, and periodontist. With the supported owner-doctor and their associate doctors on-site, I am able to discuss cases and referrals directly with the general dentist. I can also communicate directly to the other specialists when I need to refer my own patients.
Tell us more about your offices. I work for the owner-dentists at two practices: Hamner Dental Group and Orthodontics and Menifee Dental Group and Orthodontics. Hamner Dental Group and Orthodontics has a three-chair bay and two separate operatories for overflow and consults. They employ four assistants, a practice coordinator, manager, and two front desk staff members. I have been practicing at this office since July 2008. Menifee Dental Group and Orthodontics has a fourchair bay and three separate operatories for overflow and consults. They employ five
assistants, a practice coordinator, manager, and three front desk staff members. I have been practicing at this office since September 2009.
Why did you decide to focus on orthodontics? Orthodontics is more of a patientcentered specialty. I think that orthodontics is fun, and it is very gratifying to watch my patients grow up and become more confident in themselves. Orthodontics is a thinking specialty. It is the consistent challenge and thinking about each case that is really exciting.
Do your patients come through referrals? The majority of the patients are referred by the practice’s owner and associate doctors, but we are gaining more and more wordof-mouth referrals. As my practice grows, patients refer their friends and family to me for orthodontics, which I consider a great compliment. I have a reward/point system so patients can choose prizes, and I have monthly themes that the patients love. I even dressed up as Buzz Lightyear for Halloween.
How long have you been practicing orthodontics, and what systems do you use? I have been practicing orthodontics for 6 years. I use brackets from American Volume 5 Number 6
+ SUPPORTED AUTONOMY
“PDS®-supported practices have provided me the wonderful opportunity to apply a team approach to treatment, meaning the general dentist and myself, as an orthodontic specialist, work ‘under the same roof’. The close proximity I have to the general dentist and other specialists has truly allowed for communication and collaboration between everyone involved in my patients’ care. Whether my orthodontically related opinion is sought, or if I am seeking a professional opinion myself, PDS-supported offices truly facilitate clinical collaboration and comprehensive care!”

PRACTICE SPOTLIGHT Orthodontics in the MBT prescription as well as Invisalign®.
What training have you undertaken? I have earned CE credits at the annual Pacific Coast Society of Orthodontists (PSCO) and AAO meetings as well as during yearly seminars with Invisalign. I am a member of the Academy of Orthodontic Excellence (AOE) Study Club in Newport Beach, California, which is a group of orthodontists who meet quarterly and hear from speakers on a variety of subjects.
Who has inspired you? I am most inspired by Dr. Lysle Johnston, who was my instructor at Case Western Reserve University (CWRU). He taught seminars on Facial Growth at CWRU, as well as at the University of Michigan and St. Louis University. He really placed an emphasis on critical reading of the literature and thinking outside the box. He embodies the idea that orthodontics is really a “thinking” profession.
What is the most satisfying aspect of your practice? The excitement of the final deband. Everyone in the office is excited, but the patients most of all. I give the patient a goody bag, and the office sings and claps on the patient’s way out!
Professionally, what are you most proud of? I am very proud of the growth of the orthodontic programs in the offices in which I work and increasing the number of outside referrals. I am treating the general office staff and their children/friends/family, and they are my walking billboards. By striving for excellence in my clinical and professional interactions, my patients feel comfortable giving a referral.
What do you think is unique about where you practice? I think that having multiple specialists and general dentists under one roof is a unique aspect of the DSO-supported practice. The general team are always on hand to discuss orthodontics with their patients and show them the orthodontic bay. The excitement of orthodontics rolls over to non-orthodontic days. Patients like not having to go to multiple offices for dental treatment and are happy with the communication between all members of the offices. 12 Orthodontic practice
What has been your biggest challenge? My biggest challenge was getting accustomed to a large practice environment immediately following residency. I had to learn a new paperless software system and treat in a large open bay with multiple chairs. It was definitely eye-opening compared to the days of residency.
What would you have been if you didn’t become a dentist?
Top Ten Favorites 1. Practicing orthodontics 2. Spending time with family 3. Skiing in Utah 4. Spending time in Palm Springs, California 5. Reading novels (mystery and thrillers) 6. Sushi 7. Architecture and design 8. Yoga 9. Drinking a good wine with some friends 10. Books on CD during my commute
I had always dreamed of becoming an architect. There was something about the creativity, structure, and beauty of buildings and their design. These are aspects that I also recognize in orthodontics. In a way, I am the architect of the smile and the occlusion of the teeth. The harmony of aligned teeth is very pleasing, much like a beautiful building.
What is the future of orthodontics and dentistry? I think the future of orthodontics is going to include a larger emphasis on technology. Orthodontics will always be in demand due to esthetic concerns.
What are your top tips for maintaining a successful specialty practice? It is important to have excellent communication with your staff and with the referring dentists. Make all patient encounters an experience, and make them feel at home in your office. Talk to the patients to establish a rapport with them, as well as with the parents,
some of whom may become my future patients. Working in a DSO-environment, I have assistance on the administrative side, and I can focus my attention on my patients and on the clinical aspects of my practice.
What advice would you give to a budding orthodontist? Work is different from residency. Shadow another dentist to help transition into a practice environment. Find the practice environment that works for you, and work hard to be successful. Don’t forget the work/life balance. Try not to take work home, and really focus on the balance of life, including hobbies and interests.
What are your hobbies, and what do you do in your spare time? I love to spend time with my family and my two children, ages 2 and 4. I love to read, and I love architecture. As a family, we go skiing every year in Utah and love going out to Palm Springs for some sun. OP Volume 5 Number 6

CORPORATE SPOTLIGHT came to traditional bracketing. This brought about the development of the NeoMaestro™ family of brackets. This system includes the Maestro® Premium Mini-Twin® Bracket, NeoLucent® Plus™ Ceramic Bracket, and NeoCrystal™ Sapphire Ceramic Bracket. Each bracket line was developed with the vision to offer clinicians the ultimate twin bracket system where the brackets are fully interchangeable between aesthetic and metal versions for convenient and costefficient bracketing. The three bracket lines offer uniform design features as it relates to bracket sizes, compatible in/out, same base compound contour, bond strength, and more. This unique family of brackets provides clinicians with optimal benefits and conveniences, while delivering successful treatment outcomes.
The new movement in orthodontics Our commitment to partnering with the orthodontist doesn’t stop at manufacturing. We are devoted to providing complete solutions, including groundbreaking educational courses that will make you stand out within your community. Almost 2 years ago, we introduced the overwhelmingly successful obstructive sleep apnea (OSA) courses to the orthodontic community. OSA is emerging as one of the most widespread and costly health issues in the United States. As you already know, orthodontic treatment offers more than just a beautiful smile and enhanced self-esteem; it also improves quality of life by providing overall health benefits. Our courses assist orthodontists in understanding how they can play a significant role in the diagnosis and treatment options of OSA by changing the airway. Henry Schein Orthodontics developed the curriculum for these courses through collaboration with key doctors in the industry, including Drs. Lou Chmura and Dave Paquette. Across the nation, there has been huge success with clinicians who have implemented the program. And Henry Schein Orthodontics wants to build upon this success and offer new methods for the orthodontic professional to offer total health solutions in their practice.

Non-extraction treatment for face-driven treatment planning Dr. Stuart L. Frost discusses non-extraction treatment mechanics and controlling torque
ne of the many buzzwords and phrases in orthodontics that are tossed around at meetings and events is “face-driven treatment planning.” Each of us may have a different take on what this means. In a similar vein, there is a great deal of discussion around treating cases with non-extraction methods. Before addressing how to do this, the first question should be “Why?” In my opinion, the reason to consider non-extraction therapy for patients who would be served by this method is to protect and enhance the upper lip and midface for optimal support as the patient ages. I teach courses on this topic throughout the world and have employed non-extraction therapy using effective, simple mechanics that minimize complicated treatment protocols and extractions and eliminate use of many painful auxiliaries, such as expanders and distalizers. Treating cases without removing teeth or using expanders requires a heightened focus on the timing and sequence of specific yet simple mechanics — mechanics that respect periodontal health and use light forces to create space and increase the transverse occlusion. The following case discusses non-extraction treatment mechanics while addressing the issue of controlling torque to prevent front teeth from flaring. Over-torqued front teeth are difficult to correct, but avoidable, using simple mechanics and a well-timed, methodical treatment approach.
Stuart L. Frost, DDS, is an Arizona native dedicated to the advancement of orthodontics. He is a Damon™ System mentor, worldwide lecturer, and part-time associate professor at the University of the Pacific School of Orthodontics where he educates and trains residents about passive mechanics. Dr. Frost graduated from the University of the Pacific School of Dentistry in 1992, and later completed a 1-year fellowship in temporomandibular joint dysfunction and a 2-year residency in orthodontics and dentofacial orthopedics at the University of Rochester. He maintains a private practice in Mesa, Arizona. See Dr. Frost at The Forum 2015 in February. For more information, visit forum.ormco.com.

Figures 1A-1D: Pretreatment
Case presentation Diagnosis A 12-year-old male presented with severe crowding, a Class ll malocclusion, anterior crossbite, and both upper maxillary permanent cuspids and mandibular lateral incisors blocked out. One of our first steps in treating this patient was to assess his facial features. The patient was mesocephalic with
a slightly flat midface; he had an obtuse nasiolabial angle and little vermilion display. This combination of flat midface, limited lip projection, and deficient vermilion display helped me identify the fact that his facial features were not conducive to extractions. Removing teeth would have had a negative impact on his facial features long-term and would have created a concave profile as he aged. Orthodontic practice 17
Figures 2A-2E: Pretreatment
Treatment plan In addition to creating a non-extraction plan that would focus on opening space for the blocked-out upper cuspids and lower laterals, I wanted to make sure I was controlling the forward movement of anterior teeth with variable torque brackets. It would be a disservice to my patient if I opened space by flaring the front teeth forward. I use the Damon™ System appliances and take a low-friction, passive self-ligation approach to therapy, which is supported by coil springs to create space and develop the arches for maximum transverse adaptation. In a case such as this, the Damon™ System bracket technology is ideal because it provides rotational control with variable torque brackets to move teeth with minimal force. Due to the patient’s severe upper and lower crowding, we opted not to engage the .014" Copper NiTi wires in all the brackets at bonding. The lower lateral incisors were bonded from the beginning and wire tied to the half a bracket-width of coil spring (compressing the coil spring to the blocked out lateral). To ensure upright incisors, the correct bracket torque selection has to be made at the beginning of treatment. At all costs, we always want to avoid round tripping teeth and putting unnecessary force on them. To maintain good incisor position, we chose low-torque brackets for both the upper and lower arches 2-2. 18 Orthodontic practice
Along with choosing the right bracket torques, we disarticulated the arches in the posterior at bonding with bite turbos on the occlusal surfaces of the lower first molars.
Treatment progress 10 weeks into treatment/first visit after bonding We reactivated the coil springs half of a bracket width for the blocked-out cuspids and laterals. 5 months into treatment We engaged the lower laterals with a .014" Copper NiTi wire and activated the coil
spring half of a bracket width on the upper cuspids. 9 months into treatment Our goal was to open sufficient space for the cuspids to erupt so we could bond them. We took a two-pronged approach that included use of medium-light NiTi coil springs with half-of-a-bracket-width activation each 6 weeks — proceeding carefully so we would never overactivate the springs. By progressing slowly through the archwire sequence and activating the coil springs at each visit, we increased the transverse

CASE STUDY occlusion and developed the arches. We were able to broaden the arch form and slowly advance the upper incisors without flaring them. By activating the coil springs and increasing the arch width slowly, we were able to keep the upper incisors upright. Also, I believe the lips and musculature of the face helped keep the incisors from flaring. This muscle-to-coil-spring relationship allows us to keep the front teeth from being pushed out, balancing the process by acting like a lip bumper. Essentially, with the use of arch wires, passive self-ligating brackets, and coil-spring mechanics, we can work with the muscles of the face to help change the force direction and increase arch width. At 17 months into treatment A cone beam image and Panorex were taken for root position and bracket placement evaluation. At this point, the patient had
Figure 4: At 17 months, note how upright the anterior teeth are
been in a .018" x .025" Cu NiTi wire on the upper arch for 10 weeks. Notice how upright the anterior teeth are. It is amazing to me how arch development, effective variabletorque bracket selection, and light-coil spring activation can prevent incisors from flaring.
Finishing In such cases, slowing the course of treatment is crucial to creating the space needed to eliminate crowding. In this 28-month-long case, we didn’t engage the upper cuspids until 9 months into treatment, using those 9 months to open the space slowly. Additionally, we didn’t put a wire through the lower incisors until 5 months into treatment. As a result, the patient has a beautiful finish with upright
incisor display where sufficient space was created to eliminate crowding using simple, non-extraction mechanics. The crowding and blocked-out teeth represented in this case are quite common patient conditions that roughly 50% of clinicians today would treat with extractions while others would integrate the use of rapid palatal expanders to create space. With simplified, passive self-ligating mechanics, there is an opportunity to slow treatment, not only to honor the patient’s facial features today, but also to enhance them for future maturation while creating space for a more natural correction. Furthermore, creating a timeline that allows for careful and planned movement, which is monitored, helps prevent flared front teeth and loss of torque control. OP

BioDigital Orthodontics Management of patients with open bite (I): part 12 Drs. Rohit C.L. Sachdeva and Takao Kubota discuss successful treatment of open bite Introduction The open bite malocclusion commonly has three components to it: namely, skeletal, dentoalveloar, and muscular.1,2 Successful treatment of the malocclusion requires correcting the structural deviations and dysfunction when present. In addition, the influence of temporal elements such as growth direction and velocity of the maxillamandibular complex need careful consideration in deciding the timing of care. From a perspective of structural planning, the major decision that drives the correction of an open bite is the choice and selection of the treatment occlusal plane cant (slope) and level. This is based upon a consideration of a host of factors such as the amount of upper incisor display, the height of the lower facial height, growth direction, patient cooperation, stability, etc. The purpose of this paper is not to discuss the decision matrix involved in the choice of the occlusal plane. However, with pertinent patient histories, we demonstrate the value of proactivity and personalized therapeutics enabled by technologies such
as SureSmile® in providing safe, effective, and efficient care to patients (the essence of the practice of BioDigital Orthodontics) presenting with open bites.
Patient AT Patient AT, a 26-year-old female, presented with a Class 3 skeletal malocclusion, bimaxillary dental protrusion, an anterior open bite with generalized spacing in the lower anterior segment, and a forward shift of the mandible that exaggerated her Class 3 malocclusion (Figure 1). There was no evidence of a hyperactive tongue. Initial examination of the malocclusion demonstrated deviation in the anterior occlusal plane in both the upper and lower arch (Figure 2). The maxillary functional occlusal plane was selected as the treatment occlusal plane. This means that both the upper and lower anterior occlusal plane would need to be extruded to the level of the maxillary functional occlusal plane. The virtual dental simulation (VDS) plan is shown in Figure 3. Treatment was initiated by installing a lower lingual arch to maintain lower

archwidth. The arch had spurs to encourage the tongue to re-accommodate (Figure 4A). Lower anterior alignment with .016" CuNiTi AF 27°C was begun simultaneously. Two weeks later, space consolidation using sliding mechanics on the same archwire was begun. Nine weeks into treatment, the lower archwire was replaced with a .016" x .022" CuNiTi AF 27°C archwire (Figure 4B) and space closure with sliding mechanics continued. In the third month of active treatment, the upper arch was bonded, and a .016" x .022" CuNiTi AF 27°C was used as an initial archwire to achieve preliminary bracket alignment (not shown). By the end of the fourth month of treatment, the lower space was consolidated, and positive overbite and overjet established. Also, unilateral Class 2 elastics were started on the right to help correct the mild Class 2 buccal occlusion (Figure 4C). Figure 4D shows the progress of treatment at 6 months into treatment. Eight months into treatment, a Therapeutic scan was taken (Figure 5). The Virtual

Target Setup (VTS) was planned from the Virtual Therapeutic Model (VTM) (Figures 6A-C). Upper and lower 017" x .025" CuNiTi AF 35°C SureSmile precision archwires were designed (Figure 6D). The SureSmile precision archwires were inserted 6 weeks post therapeutic scan, and the patient was asked to wear bilateral Class 2 elastics and diagonal anterior elastics to correct the midline (Figure 7). The patient was evaluated 8 weeks later. Class 2 correction and normal overbite were established (Figure 8). A month later, the patient was debonded (Figures 9 and 10). A comparison of the Virtual Diagnostic Simulation (VDS) to the Virtual Final Model (VFM) demonstrates that the treatment objectives were met (Figure 11A). Also, Figure 11B shows that the upper and lower anterior occlusal planes were successfully treated to the maxillary functional occlusal plane. Closer examination of the final occlusion shows a “rat hole” in the upper right lateral and lower canine area. This was anticipated in the Virtual Diagnostic Simulation and is a result of the anomalous morphology of the distal incisal line angle of the lateral incisor (Figure 11C).

Patient YM Patient YM, an 18-year-old female, presented with a Class 2 malocclusion and an anterior open bite with severe arch length discrepancy in the upper arch (Figures 12 and 13). Extraction of the upper first bicuspids was planned to treat the arch length discrepancy and correct the open bite. The maxillary functional occlusal plane was selected as the treatment occlusal plane. This meant that the upper incisors would need to be extruded. The lower arch would be treated non-extraction, and lower anterior interproximal reduction would be performed to alleviate lower crowding and minimize the flaring of the lower incisors. The Virtual Diagnostic Simulation plan demonstrates the planned tooth movement (Figures 14 and 15).
Treatment was initiated in the upper arch. A transpalatal arch was used to maintain archwidth and augment anchorage during space closure. Separate canine retraction was initiated with a .009" ligature wire rope tie (Figure 16A). By the third month, the canines were substantially retracted. At this time, the upper arch was bonded. In the upper arch, a .016" CuNiTi AF 35°C archwire was inserted to achieve anterior alignment. Second bicuspids were not bonded to further decrease the stiffness of canine molar archwire segment (Figure 16B). Four weeks later, the lower arch was bonded, and a similar archwire as for the upper was installed to achieve lower alignment. Minimal interproximal reduction was initiated amongst the lower anteriors at this time (Figure 16C). Five months
into treatment, the patient was requested to wear box elastics to counteract the reciprocal intrusive effect on the anteriors as the canines extruded (Figure 16D). Six weeks later, the initial upper and lower archwire wires were replaced with arch .016" x .022" CuNiTi AF archwires (Figure 16E). The patient’s progress is seen 7 months from the beginning of treatment (Figure 16F). Eight months into treatment, the mid-treatment scan of the patient was taken (Figure 17).

ORTHODONTIC CONCEPTS AF 35째C SureSmile precision archwires were designed (Figure 18). The precision archwires were inserted 6 weeks later. At this time, the patient was asked to continue wearing the anterior box elastics and also wear Class 2 elastics (Figure 19). The patient progress at 9.5 months in treatment and 8 weeks
post SureSmile archwire insertion is shown in Figure 20. The patient was debonded 1 month later (Figures 21 and 22). The superimposition of the Virtual Diagnostic Simulation to the Virtual Final Model shows that most of the objectives were met. However, the overbite was left a little shallow (Figure 23).
Polishing the marginal ridges of the upper incisors and some additional interproximal reduction of the lower anteriors would have created additional overjet into which both the upper incisors and lower incisors could be extruded to provide a better overbite relationship (Figure 24).

Conclusions Effective and efficient treatment of patients with open bites requires proper diagnosis, planning, and careful management. Patient participation is of vital importance, especially if elastic wear is required. With SureSmile, it is necessary for the clinician to carefully plan and orchestrate orthodontic tooth movement during the pre-SureSmile therapeutic phase of treatment as well.3-16 This implies that the conventional and SureSmile therapeutic phase of treatment should be driven by consistent objectives based upon a formal plan of care designed at the beginning of treatment. In patient YM, it would have been judicious not to have used a continuous archwire alignment of the maxillary dentition. The reciprocal intrusive force generated on the anterior teeth as the upper canines extruded put the patient at risk in terms of exaggerating the anterior open bite.

An introduction to reviewing CBCT images Dr. Andrew Trosien discusses the benefits of a CBCT view
one beam computed tomography (CBCT) is becoming much more common in dentistry. A few years ago, it was unusual to get images from a colleague’s CBCT machine, whereas today it is not unusual for a few doctors in a given town to have a CBCT machine. But unless you recently graduated from orthodontic residency, you haven’t had access to much training in the interpretation of CBCTs. Further compounding the issue is the fact that much research on and with CBCTs has occurred within the last few years. So forward-looking practitioners would be wise to learn about how to approach a CT scan, and what to look for, what to measure, and what it means. Some debate remains as to whether CBCT should be used only for select patients or as a complete replacement for traditional orthodontic X-rays. Much of this dispute revolves around the radiation doses of CBCT and the fear that patients are subjected to excessive levels of CT radiation. However, these fears are unfounded. While a traditional, hospital-based spiral CT of the head give a dose of 860 microsieverts (the equivalent of more than 45 panoramic X-rays), the cone beam CT gives much less.1 The difference is related to the design of the machine, and the difference between the cone and spiral beams. For reference, the extended field of view (full head) on an i-CAT, with the traditional .3 mm3 voxel size at 8.9 seconds, results in a dose of 74 microsieverts, which

Educational aims and objectives
This article aims to discuss the advantages of CBCT view for orthodontic diagnosis.
Orthodontic Practice US subscribers can answer the CE questions on page 36 to earn 2 hours of CE from reading this article. Correctly answering the questions will demonstrate the reader can: • Realize the radiation differences between CBCT scans and panoramic radiographs. • Identify anatomy that can be distinguished on slices and volume CBCT views. • Recognize some usual and unusual anatomical discoveries on CBCT scans. • Read about some details that can be viewed on CBCT regarding degenerative joint disease. • Identify when it may be necessary to outsource the scan for a reading.
Figure 1: Coronal, axial, and sagittal CBCT slices (with an additional image of the volume)
is less than four panoramic radiographs.1 And for a low dose “progress” scan, with a 0.3 mm3 voxel and 4.8 seconds, the dose is lower than 1.5 panoramic radiographs.1 The amount of radiation in a full-mouth series with F-speed film is the equivalent of nine panos,1 while the CBCT gives an amazing amount of information with minimal radiation dose. Fundamentally, a CBCT can be viewed in two different ways: As slices or as a volume. It’s not a matter of which you prefer — both are important. Certain features are best viewed in slices, while others are best viewed in the volume. Initially, when viewing a CBCT as part of a formal work up, most doctors will start with the slice data (Figure 1). The idea is to scroll through the volume, “slice by slice,” and look for anything out of the ordinary. It takes a while to identify what
Figure 2: A coronal slice
is considered normal, and what is actually abnormal. When starting with the coronal slice (Figure 2), we can scroll through and see the maxillary sinuses, the nasal septum, the nasal turbinates, the ethmoid sinuses, and Volume 5 Number 6
Figure 4: Mucoceles in the maxillary sinuses

Figure 6: Wax in the right ear canal
the ear canals. (Of course, most anatomy can be seen with this view, but anatomy like the teeth, the maxilla and mandible, condyles, etc., are more easily seen in other CBCT views.) The maxillary sinuses can be completely occluded if the patient has a cold (Figure 3) or can have a thick lining, showing inflammation. There may also be what appears to be a small “balloon” in the sinus, which is a harmless mucous retention cyst (Figure 4). It is the balloon-like appearance that is indicative of a mucous retention cyst. In contrast, if it does not have that smooth, “inflated” round appearance, it may be a tumor (Figure 5) and should be reviewed by a radiologist. Surprisingly, it is not unusual to see a really small maxillary sinus, which is just an aplasia, and typically needs no intervention. The ear canals should be generally open, though it is not atypical to see an
accumulation of wax (Figure 6). However, if anything is seen in any of these areas that looks particularly radiopaque, it’s probably something that should not be there, and should be checked out — like this piece of metal from the tip of forceps used to remove an ear tube (Figure 7). The coronal view also shows the tongue. While not diagnostic of a problem, it is worth noting if there is a space between the top of the tongue and the palate in this view (Figure 8). It has been shown that expanding the maxilla creates a larger volume for the tongue to occupy, allowing it to migrate away from the back of the throat, opening the airway.2 A low tongue posture with the subsequent narrow maxilla may lead to a treatment plan involving maxillary expansion. Next, viewing the volume from the axial view, we can scroll through the frontal sinuses, the ethmoid sinuses, the nasal

septum, and the maxillary sinuses. Sometimes an ordinary-looking structure in the coronal view of the maxillary sinuses can be viewed in the axial view for more information. The axial view offers the best view of the nasal septum. A deviated septum is not atypical and requires nothing more than informing the patient or the parent (Figure 9). The sagittal view gives the best view of the airway. The adenoids, soft palate, and base of the tongue are all structures that can occlude the airway. While we cannot do any sort of volume measurements on this sagittal view, it does give an indication of what structures are responsible for the airway occlusion. The volume view gives an overall assessment of the symmetry and structure of the skull and jaws. This view allows us to check the maxilla and mandible for supernumerary teeth, ectopic teeth, missing teeth, etc. We can toggle the view setting to show just osseous tissue to see the level of the bone around the teeth, as well as its thickness facially and lingually to them. Switching to an airway view allows measurement of the pharyngeal airway volume (Figure 10). The CBCT provides a reliable and accurate airway volume measurement.3 If the minimal crosssectional area of the pharyngeal airway is below 50 mm,2 then the patient is at high risk for obstructive sleep apnea. Between 50 and 100 mm2 indicates moderate risk, and greater than 100 mm2 is low risk.4,5 The CBCT offers a superior way of assessing the condyles. Prior to CBCT, a tomographic series was routinely used to view the joints, and the quality of the images was much lower than what we now receive from a CBCT. As research continues with CBCT, we should gain more knowledge about the temporomandibular joints (TMJs). The condyles are best viewed in their own dedicated slice window. 34 Orthodontic practice

Figure 12: A normal condyle in sagittal view. Note the smooth cortical outline and anterior curvature of the head of the condyle
The principal abnormality that one looks for in TMJs is degenerative joint disease (DJD). DJD destroys the articular tissues and occurs when the remodeling capacity of the articular tissues is exceeded by functional demands. The primary diagnostic feature is a lack of cortical outline along the superior aspect of the condyle. A cessation of the cortical outline, or cortical fuzziness, indicates active degeneration (Figure 11). Because CBCT screening includes an
analysis of the TMJs, it is worth reviewing the continuum of temporomandibular dysfunction. A normal joint presents a smooth, rounded cortical outline with an anterior cant (Figure 12). Once a disc displacement develops, some sclerosis and flattening along the superior anterior aspect of the condyle can be seen. Next, the condyle develops further flattening, and finally results in a nonreducing disc. At this point, erosions that characterize active DJD often develop. As Volume 5 Number 6
patient). Resolution of the disease can take months and needs follow-up with periodic CBCT scans. Clinicians should note that the shape of the condyle is not the issue as much as the presence or absence of cortical outline. A bifid condyle (Figure 14), while having a divot in its center, is a normal variation, has a continual cortical outline, and does not indicate DJD. Given the nature of degenerative joint disease and the difficulty for novice CT readers to confidently diagnose it, there are a number of services for outsourcing the reading. BeamReaders, started by Dr. David Hatcher, is the most well-known of these.
Some doctors choose to upload every CBCT taken for a BeamReaders report. Others choose to upload those images that have areas of suspicion. These services have a staff of doctors with a significant amount of experience and provide an abundance of knowledge. The most difficult thing to learn when interpreting CBCT scans is the variations of “normal.” After viewing a few dozen scans, doctors will develop a familiarity with the different variations of normal. As with any new technology, orthodontists should avail themselves of literature, courses, and hands-on experiences to enhance their knowledge and interpretive skills with CBCT. Practice makes perfect only when the practice is perfect. OP

the joint attempts to heal, bone will accumulate on the margin of the condyle, giving the characteristic “beaking” appearance of osteophyte formation (Figure 13). At this point it is not unusual to see subchondral bone cysts, which are characterized by a radiolucency below the cortex of the joint.6 From an orthodontic perspective, a patient with a history of DJD is less troublesome than a patient with active DJD. In other words, finding beaking and reduced condylar height should not be as alarming as seeing an incomplete cortical outline, which as the hallmark of DJD, contraindicates orthodontic treatment. Orthodontic therapy in the presence of DJD will exacerbate condylar resorption much like orthodontic treatment in the presence of active periodontal disease will exacerbate alveolar bone loss. If a patient has active DJD, the orthodontist may choose to wait (in the absence of symptoms) or to make a centric relation bite splint (for the symptomatic

Dr. Harold F. Menchel discusses a disorder that can have significant effects on orthodontic treatment planning and treatment Abstract A past article has discussed the orthodontic implications of TMJ arthritis.1 In this article, the author proposes a mechanism of infectious TMJ arthritis in infants related to otitis media. This infection causes condylar lysis and altered growth causing occlusal changes.2 This disorder will have significant effects on orthodontic treatment planning and treatment. A case history is presented to support this hypothesis.
Introduction Septic bacterial joint arthritis affects populations of older patients (greater than 55 years) and infants. The most common joints affected are the hip and knee in children. Over a third of the incidence is in infants below the age of 2. The incidence is estimated at 6/100,000.3 The most common isolated organisms are Staph aureus and H. influenzae. This is a focal infection and needs to be distinguished from Lyme arthritis, which is more systemic and caused by the spirochete Borrelia burgdorferi.4,5 There are previous reports of septic TMJ arthritis related to middle ear infections in the literature.6,7,8,9 There are also reports of spread of bacteria to the joints from bacterial pharyngitis caused by streptococcal infections. It is controversial, however, if this is from direct infection or is a reactive arthritis.10

Correctly answering the questions will demonstrate the reader can: • Realize that TMJ arthritis is a possible mechanism for degenerative joint disease in infants and children. • Identify some of the symptoms of TMJ arthritis. • Recognize the differentiation between juvenile rheumatoid arthritis (JRA) and TMJ arthritis. • See the importance of controlling mechanical stress is also vital in these patients.
severe left ear pain, preauricular swelling, and limited opening. She reported occasional mild pain on the left only over the past few years, which had increased over the past month. She was unable to chew or open her mouth without pain. She was unaware of bruxism. There was no temporal pattern to her pain. The patient reported occasional moderate temporal headache on the left side only.
Medical history Positive for numerous episodes of otitis media as infant with pressure equalization (PE) tubes placed to drain infection. The medical history was otherwise unremarkable.
Dental history The patient had been treated orthodontically with a palatal expander to correct a
unilateral crossbite at age 8. The records were supplied and indicated that the crossbite was reduced with centered midline. The patient had reported bite changes and was scheduled for definitive orthodontic treatment when she was referred for TMD pain and dysfunction.
Objective findings The patient had severe pain to palpation of the left TMJ with mild pain on the right. She also had severe pain in the muscles of mastication more on the left. There was evident hyperalgesia in the left preauricular area, but no swelling was noticed during examination. She had no cervical pain. Occlusal evaluation revealed a Angle Class III canine relationship on the right and a Angle Class I relationship on the left with the canine in crossbite.
Case history Subjective A 13-year old patient was referred to an orofacial pain dentist with symptoms of Harold F. Menchel, DMD, is a worldwide educator on the topic of orofacial pain. He is adjunct faculty at Nova Southeastern Dental School in Fort Lauderdale, Florida, educating both undergraduates and graduate residents.

CONTINUING EDUCATION Maximum intercuspation = centric relation, and there was no evident slide or shift on closing. She deviated to the left on opening and protrusion. Her maximum intercisal opening was 35 mm with a “soft” end feel. After ice and gentle manipulation, the patient opened to 45 mm. There was a midline shift to the left of 3 mm, decreased posterior overjet on the left, increased posterior overjet on the right. Vertical overlap was 15%, and horizontal overlap 1.5 mm on the right and 2.5 mm on the left with an evident open bite in the right anterior. The patient has a facial asymmetry to the left (Figure 1).
continues to wear the splint at night. The splint is checked at 3-month intervals. Notice the changes in Figure 7.

Imaging Imaging for the patient is below. MRI imaging was initially planned, but due to patient’s progress, this was deferred. No initial TMJ surgery was anticipated.
Figure 4: Presenting Panorex. Notice the flattened left condyle (white arrow) and the bilateral calcified mastoid processes, which can be indicative of resolved mastoiditis
TMD Pain management involved standard TMD conservative therapy,12 resting the mandible with soft diet and behavioral modification (no gum chewing, no resting chin on hand, etc.), and home care (ice for 72 hours followed by moist heat). The patient was prescribed NSAID (Naprosyn 220 mg BID [Aleve®]), acetaminophen/diphenhydramine (Tylenol® PM), and QHS to aid sleep and for pain. She was referred to physical therapy for further evaluation, TMJ mobilization, and modalities as necessary for reduction of inflammation and range of motion improvement. A lower flat plane orthotic was placed with mandatory nightwear and day wear as necessary for pain. The occlusion was very unstable, and splint adjustments were made once a week for the first month. The patient responded very well and in 6 weeks had minimal pain to loading, an opening of 50 mm with no deviation, or limitation in range of motion (ROM). She

Figure 7: The splint was adjusted to equal bilateral contact. Notice the changes over a 3-month interval where the patient has lost contact with the incisors, and she is hitting more heavily on the posterior, particularly on the left. This is good indication of joint erosion or remodeling from the arthritis
Occlusal — orthodontic This patient has an unstable occlusion due to continuing condylar erosion and limited growth in the left condyle. Final orthodontic correction is contraindicated at this time and will not be done until full growth (in females 16-18 years). There is certainly indication in this case for possible orthognathic correction. Records are being taken annually to chart the progression of the disease. Although this is a unilateral lesion, further imaging and diagnosis will be necessary before the final treatment. Inflammatory arthritis needs to be ruled out. This will involve the protocols mentioned in a previous article in this series.1 This patient is now 15 and not yet at full growth. Her progress will be documented in further articles.
Discussion This case history is proposed as a possible mechanism for degenerative joint disease in infants and children. This mechanism is shown in the following figure.
Figure 8: This is an axial CT through the external ear of an 8-month old infant. Labeled are the external ear canal (EAC), the condyle, foramen of Huschke,13 (HF) a communication between the EAC and the infratemporal, which closes at age 3. Drainage of the middle ear with perforation of the tympanic membrane (TM) with pressure equalization tubes (PE tubes) can afford a communication where pus can go from the middle ear and infect the TMJ (white arrow)
Although the incidence of TMJ septic arthritis is unknown and certainly uncommon, this author has seen a number of cases with similar presentation and history over the past 20 years. Injury, of course, cannot be ruled out as a cause, but in this case, and similar cases, there are no reports of injury. TMJ injury is rare in children.14 Notice that the joint changes were evident on a previous Panorex Volume 5 Number 6
Figure 11: Facial asymmetry increase Figure 9: TMJ injury is rare is children. Notice that the joint changes were evident on a previous Panorex taken 5 years before when the patient was 8 years old 14
Also notice how the facial asymmetry and malocclusion is increasing in the next figures that follow.
Clinical implications and conclusions The author is proposing a mechanism for TMJ arthritic degeneration in children, which could be overlooked.15,16 It is essential that in infants with perforation of the tympanic membrane (TM), either with PE tubes or from TM rupture, that these patients be treated more aggressively with antibiotics than for routine cases of otitis media to prevent septic arthritis. Pediatricians need to be aware of the possibility of this disease. This disorder can be screened at a young age and long-term treatment planning coordinated with the dentist, orofacial pain dentist, and oral surgeon. It needs to be differentiated from juvenile rheumatoid arthritis (JRA).17 In JRA, the lesions are almost always bilateral, and the patient will have a general feeling of malaise and migratory joint pain.
Rheumatology evaluation is always mandatory in these cases, and any long-term medical management should be under the care of this physician. If there is no systemic component to the arthritis, and it is a form of osteoarthritis, secondary to bacterial infection, medications are not indicated to alter the disease progression. The responsibility falls on the orthodontist and pediatric dentist to diagnose and manage occlusal changes in these patients.18 Controlling mechanical stress is also vital in these patients, and if the patient is a bruxer, a hard acrylic night splint is recommended even without signs and symptoms of TMJ pain or dysfunction.

Tiffany’s story Dr. David Kemp recounts a collaboration that changed a patient’s life
here are endless mountaintop milestones I am proud of throughout my 28 years of orthodontic practice. There is one story, however, I am most proud of. Tiffany was a sophomore in college, and, because of the appearance of her teeth, she made a decision to go to a local dentist with money in hand to have her upper teeth removed for denture placement. The local Affordable Dentures® of Nashville refused Tiffany’s wishes and mentioned there was a better solution. I am very thankful for the dentist who recognized that Tiffany needed something special to happen to help her with her situation. He referred her to the show “Extreme Makeover,” and she applied for a spot on the show. After a short while, the lead producer of the show called Tiffany to tell her that, while her situation with her 40 Orthodontic practice
smile was really bad, he could not produce a full episode for her. However, he referred her to Dr. Dennis Wells of Nashville Center for Aesthetic Dentistry. Dr. Wells introduced Tiffany to the philanthropic Pinnacle Seattle Study Club of Nashville, which chose without hesitation to take on Tiffany’s case. We were delighted to have the opportunity to change a most wonderful young lady’s life through our professional abilities. I want to thank Dr. Michael Skinner for his periodontal treatment for Tiffany and Dr. Dennis Wells of Nashville Center for Aesthetic Dentistry for his restorative veneer treatment for Tiffany. The following is how Tiffany tells her story. “Every time I would smile or laugh I would cover my mouth. When I was 18 years old, I was starting college, and I decided I wanted to have a fresh start meeting new people at
college. I was so embarrassed for anyone to see my teeth, and that made me revert inward. I made a decision I would change this, so I decided to get my upper teeth pulled and a have dentures placed. I was thinking this would give me a better appearance in the community.” Tiffany’s desires were, “I just want a normal, straight smile, for my teeth to be the same color and not splotchy. I would really like not to show as much of my upper gum, and I would love to have a beautiful smile.” Tiffany’s interests and logistical issues due to traveling back and forth for care from college were considered when developing a treatment plan. She lived almost 2 hours away at college. The treatment goals focused on correcting her excessive gingival display, asymmetry, occlusal plane, short clinical Volume 5 Number 6

crowns, and mottled enamel after eliminating generalized gingivitis and achieving oral health. The orthodontic strategy was to treat the patient without extractions. The focus for final position of Tiffany’s upper anterior teeth was to establish gingival marginal heights with symmetry for esthetic veneer placement. Clarity™ (3M Unitek) brackets were positioned at different heights on the left and right upper anterior teeth to ensure the leveling of the anterior occlusal plane. Variable Prescription Orthodontics (VPO) was used by inverting the brackets on the upper anterior teeth to provide the best possible torque mechanics throughout orthodontic treatment. We wanted to retract her anteriors as much as possible, making way to provide ideal veneer placement. An indirect orthodontic bonding technique was used to provide accurate progressive placement of the brackets. The gummy smile was also substantially improved by the simultaneous intrusion and retraction of the upper anterior and posterior teeth. Cosmetic crown lengthening was performed to establish more ideal proportions of the anterior teeth as well as to continue to reduce the gingiva display. Ten years later, Tiffany says, “My goal was to become a lawyer, and I know if you are in the courtroom, you are in front of people, meeting with clients all the time, you have to have a nice smile to be presentable. My transformation journey that Dr. Kemp, Dr. Skinner, and Dr. Wells provided gave me my life back and truly gave me the confidence to become a lawyer. I finished law school with honors in Memphis and have practiced family and personal injury law for the past 2 years. I have now moved back to middle Tennessee, and I am interviewing law firms for a job in real estate law in the Franklin and Brentwood, Tennessee area. “This was a life-changer event for me. I now have the confidence to go up to people and be able to talk to them with ease. I do not have to cover my mouth when I smile anymore. I am so much more outgoing. I love to put myself out there. I am not trying to hide, and I am not as timid. This has given me the ability to let my personality shine. I am not embarrassed any more. I still get compliments on my smile all the time, and I never would have dreamed that I would ever have that experience. “This journey has improved my quality of life in an unbelievable way. I used to keep to myself and was really quiet. Now that I have a great smile, I can put myself out there, and

I am not afraid to talk to people. I now can smile freely, and I have so much more selfconfidence. This experience has given me the freedom to truly be who I want to be.” Treating Tiffany and watching her life story unfold has been one of my greatest professional and personal experiences. To see her reach her full potential and hear her tell her story is more rewarding to me than words can really address. This story and
the stories of all my patients capture what my idea of being a successful orthodontist is really about — changing people’s lives in a positive way by creating their beautiful smiles.

A more controlled approach to aligner therapy Dr. William Thomas discusses an aligner treatment alternative
ou have a new prospective patient waiting in your consult room; your treatment coordinator (TC) has provided the patient with the various alternatives to treatment and has informed you that the patient is set on being treated with aligners. The patient records indicate a need for fixed Class II Treatment Mechanics, and the patient’s mandible is somewhat retrognathic. Your training and experience tell you that the patient needs fixed therapy and does not qualify for pure aligner therapy. Your TC then drops the bomb. She also mentions that they have already seen one of your largest referring dentists and have been quoted a fee for aligner treatment that is 20% less than your fixed appliance fee. So now what? This scenario is happening in orthodontic offices across the country. Patients today demand appliances that may or may not be optimal for their specific needs. Trying to convince patients and sometimes their parents that certain treatment modalities may not be best for their case is often like trying to sell ice to an Eskimo. Many orthodontists are caught in a variable quandary: “Do I treat the patient with the appliances they desire and make them work, or do I recommend the appliance therapy I feel best meets their dental needs, putting me in an uncomfortable position with my referring dentist?” The resolution most often falls somewhere in between standing firm or losing the case. Clear aligners and positioners have long been used to straighten and retain teeth. Clear thermoformed plastic with varying degrees of elasticity, formed over models of gradually aligned teeth, have been around the orthodontic world for decades. William Thomas, DDS, MS, has been an orthodontic specialist in the field of dentistry for over 25 years. He earned both his dental and orthodontic degrees from Georgetown Dental School in Washington, D.C. Upon graduation from dental school, he was selected by the prestigious National Dental Honor Society OKU, received awards for outstanding graduating senior in prosthodontic (dentures) and pediatric treatment, and graduated in the top 5% of his class. Dr. Thomas is in private practice in Poway, California. He has presented at a various orthodontic meetings and study clubs, and his work has been published in a variety of orthodontic trade magazines.

My history in orthodontic software used for diagnostics and treatment planning dates back to the mid-1990s when I worked on developing a software program with Dr. Larry Andrews. I helped develop software that prescribed variations in bracket prescriptions based on Dr. Andrews’ Six Keys to Normal (Optimal) Occlusion™ and his Six Elements (6E) Orthodontic Philosophy™. This was developed long before CAD-CAM dentistry made any significant impact in our specialty and was well ahead of its time. Later, as I developed my practice, I joined the Ormco™ Dr. Thomas showcases a set of Orchestrate 3D™ printed models that will training team lecturing on the be used to fabricate aligners.

More ment options to make the appliances work recently, intraoral scanning has fast taken better, especially for my Class II patients. Still, hold in orthodontic offices, and I feel we are I felt limited in what I could accomplish with the appliance systems available. now reaching the next level of digital orthodontic care. Additionally, I found that many of my local As I strive to develop improved treatment general dental colleagues continue to offer alternatives, my patients have become more aligners in their practices, often at a lower educated and more demanding regarding the fee than mine. It appears to me in my area that approximately 60%-80% of the general appliances they want — esthetics, comfort, and speed being their priorities. In my pracdentists are actively providing clear aligner tice, new patient consults for clear aligners treatment. It seemed like I was caught in a have increased dramatically; however, some Catch-22, having to re-differentiate my pracof these patients, from my education and tice and specialty, yet still offer an aligner training, did not “qualify” for the appliance service to my patients. Last year, I learned about a new system they desired. Still, these patients demanded called Orchestrate 3D™. Orchestrate 3D™ more esthetic options without using fixed appliances. was founded by a group of orthodontists lead by Dr. Todd Ehrler, who developed After several years of treating with the software that allowed orthodontists to available aligners on the market, it began to create a financial nightmare in my practice, completely control their digital set ups and driving my overhead up, severely taxing my dental movements. cash flow, and creating a gradual loss of Using any open STL file, Orchestrate control in my treatment. Chasing the “volume 3D™ Software enables the doctor and staff to have complete control of determining the discount” seemed to me like being on a wheel that kept the reward just slightly out of reach velocity of dental movements, allowing a varifor my “average” size practice.

customized to the patients’ needs. So far, I have started over 150 patients with Orchestrate 3D™. Orchestrate 3D™ allows me an ability to provide aligner therapy combining thermoformed materials with variations in thicknesses allowing for a varied modulus of elasticity. Orchestrate 3D™ also allows me to design customized attachments in a variety of geometries, which allow us to better intrude and extrude teeth. With Orchestrate 3D™, I am treating cases that I would have never treated with any other outsourced system. I feel like I am in much better control with the Orchestrate 3D™ design software and now have the ability to do practice-designed setups that, in my hands, is better aligned to the biomechanical needs of a specific case. Analogous to multiple arch wire progressions we have all followed with our fixed therapy, I have developed a systematic multi-thickness progression using varying thicknesses of thermoformed retainer material. In my hands, this has greatly improved tooth movement and what is commonly called “tooth tracking,” along with the ability to completely customize more optimally designed attachments using the Orchestrate 3D™ Smile Design Software. Using Orchestrate 3D™, the orthodontist determines the velocity of tooth movements he/she feels comfortable with given the case to be treated. Coupled with these doctordetermined movements, clinicians can customize their own attachments using the Orchestrate gyroscope tool. This has allowed me to better control my dental movements in all three dimensions.
Dr. Thomas designs a treatment plan utilizing attachments in the Orchestrate 3D™ software
I continue to be impressed with the speed and efficiency of treatment. In an effort to maximize tooth movement and tracking, I prescribe two to three vacuumformed aligners made on each 3D printed model. Initially, I used Dentsply Essix™ in three thicknesses: .030, .035, and .040. I am now starting to use the Forestadent® Track® material fabricated on its Track machine. I am also collaborating with Specialty Appliances lab in Atlanta, Georgia, on expanding scopes of hybrid aligner therapy using fixed Class II appliances along with its manufacturing aligners using my variable thickness aligner sequences. During early stages of treatment, I desire low initial force systems; therefore, the first two 3D printed upper and lower models are made with vacuum formed aligners using .030- and .035-inch thickness. This enables the dentition and periodontal ligament apparatus the ability to initiate tooth movement and help transition the patient past the initial soreness phase. Occasionally, I use an initial .020 for my initial “adjustment” aligner. My standard treatment protocol is to use .030 and .035 for the majority of the treatment. When the case has progressed
to the final two models, I incorporate a final stage protocol of .030 and .040. If I am really concerned about extrusion and tooth tracking, I’ll include three aligners per 3D model — .030, .035, and .040. In my practice, this regiment has greatly improved the speed of dental movement through dramatically improved “tracking” and also has seemed to improve my patients’ compliance. In the cases where teeth do not seem to be tracking as fast as I would like, I can go back and adjust the digital setup and get new printed models in a few days. Although I am still finishing many of my Orchestrate cases, I feel as if I use fewer aligners than I used to while achieving the same, if not better, tooth movement. With Orchestrate, I keep all of my printed models in-house and can fabricate a replacement appliance often on the same day. Once I fully incorporate an in-office 3D model printer, storage of these models will become obsolete. If a specific model is required, it will simply be printed on an as needed basis. In my practice, the biggest benefits with the Orchestrate 3D™ system are that I see improved control in treatment progression

TECHNOLOGY and am able to continually refine tooth movements anytime during treatment with limited additional cost. Typically, I have four to six “setups” or 3D printed models made at a time, on which two to three aligners are vacuum formed on each as previously described. This treatment strategy produces 10-18 aligners per arch and enables changes quickly and efficiently if needed during treatment progression. Prior to using Orchestrate 3D™, I was locked into a treatment plan and appliances that were predetermined before the patient ever started treatment. With this new technology, I can now make additive clinical decisions and modifications regarding tooth movement and force applications during the course of orthodontic treatment, which has given me much better control of my treatment and a new outlook on using aligners in my practice. Further, through my previous experience with aligners, I had limited ability to monitor or manipulate dental tracking easily and efficiently during treatment; therefore, some cases fell behind or had to be retreatment planned. This meant new impressions, lost revenue, lost patient goodwill, and lost profitability. By treatment planning with Orchestrate 3D™, I focus on maintaining facial-lingual and mesial-distal movements to approximately 0.3 mm per stage, and I keep extrusion and intrusion movements down around 0.1 mm per stage. By adding the option for variable force levels delivered by multiple material thicknesses, I have seen dramatic improvement in how fast teeth are moving, and I feel like I am using fewer appliances to gain my desired dental movements due to dramatically improved tracking. An alternative strategy to enhancing more difficult movements — i.e., extrusion — is to combine simultaneous lingual attachments. The 3D printed models provided by Orchestrate 3D™ resist tooth fracture better than stone models. Using Pam® as a nonstick material on the printed models enables aligners to be removed easily and efficiently, allowing my lab technician to fabricate multiple aligners on each model easily without excessive breakage. In some cases, seating attachments are critical to achieve specific tooth movements with clear aligners. Typically these are bonded onto teeth with a high strength composite resin. With the Orchestrate 3D™ software system, precise and completely custom precision attachments are designed by the doctor enhancing treatment efficiency. Initial attachment bonding trays are typically 44 Orthodontic practice

made using .020 thickness Essix™ material. When attachments are used with the Orchestrate 3D™ software, an additional “setup” or 3D printed model is printed along with the aligner models. I term this Stage 0. With Orchestrate 3D™ software, I have been able to design more optimal attachment geometries that have greatly enhanced the speed of treatment and, in my practice, reduced the number of aligners needed compared to an outsourced lab service. Combined with variable modulus of elasticity retainers we can fabricate in my lab, Orchestrate 3D™ opens up a much broader range of patients whom I now feel comfortable treating with clear aligners. Orchestrate 3D™ also allows me an option to treat patients initially with fixed labial or lingual brackets to achieve difficult leveling and aligning, and then switch finishing with Orchestrate planned finishing appliances. In short, Orchestrate 3D™ has given me an in-sourced system of which I am in full control, both from a treatment aspect and from a practice overhead and cash flow standpoint. Prior to using Orchestrate 3D™, we found ourselves trying to convince perspective patients that my clinical training and specialized education was worth a premium fee and large down payment to cover all startup costs. However, for those patients who desired a second opinion and who wanted clear aligner therapy, they often choose to get treatment from a general dentist who offered the same system and a reduced fee. In the past, I had a choice: Should I
reduce my fee, or should I lose the patient start? With Orchestrate 3D™, I feel I can now offer a premium treatment with improved clinical advantages at a cost that allows me to treat patients with the same fee as my fixed appliance therapy. When given the choice of braces or clear aligners — at the same cost — the choice has been a resounding 90% clear aligners. Now when my TC comes to me with prospective patients who desire therapy with customized aligners, I cannot wait to tell them about this new technology, which allows us improved clinical options and still gives them the clear aligner appliance they desire. As we learn more about how we can utilize Orchestrate 3D™, I feel my practice continues to embrace new opportunities that we never had before. My career has been an interesting journey, and I now, once again, look at my cases in a totally new way — through a new paradigm in which clear aligners can finally be highly effective clinically while also financially palatable and cash flow friendly. By using Orchestrate 3D™, my creative treatment planning has only now just begun! I am now working with Orchestrate 3D™ to help educate clinicians and their staff to realize the same benefits we have enjoyed in my practice.

CBCT and 3D imaging goals for orthodontic patients Dr. Duane Grummons discusses how CBCT equips the orthodontist regarding unerupted teeth, facial asymmetry, craniofacial anomalies, temporomandibular (TMD) disorders, airway conditions, TAD planning, and true root information in the region of interest (ROI).
he AAO recommends orthodontic screening by age 7. To get adequate diagnostic jaw and bite information, the use of low-dose CBCT imaging is often indicated and preferred. We know enough about its application to consider it the imaging of choice for comprehensive orthodontic treatment.1 This reveals eruption guidance and jaw imbalance decisions and airway/TMJ problems that influence facial growth and development. Patient age is less important since imaging relates to the individual needs and timing. Clinicians establish imaging goals and select the optimal imaging modality to answer clinical questions. The imaging goals and prescribed need for a low dose, limited field of view (FOV) CBCT scan should be determined after a careful clinical examination. The doctor first evaluates to determine any cone beam imaging need, rather than all patients getting a scan. CBCT is the preferred imaging modality considering patient risks (radiation dose) while also recognizing the implications of not utilizing CBCT and having incomplete diagnostic information.
New thinking and imaging perspectives Perhaps we as a profession, should change the pretreatment records as a result of technological changes in our profession with CBCT. The standard of care has been elevated such that 3D imaging should be an essential part of certain imaging decisions.2 We should image wisely and always adhere to the ALARA principle. We can obtain a Duane Grummons, DDS, MSD, is a board-certified orthodontist with a specialty practice in Spokane, Washington. He has published orthodontic articles and chapters, and has lectured for most U.S. and worldwide orthodontic organizations. Dr. Grummons is internationally recognized for his clinical approaches to facial orthopedics, facial asymmetry, TMD management, and non-extraction orthodontic treatments. Dr. Grummons is Associate Professor of Orthodontics at the Loma Linda University Medical Center Orthodontic Department. He has appeared before many dental, surgical, and medical conferences, and has made radio/TV appearances. He can be contacted at email@example.com.

CBCT scan for patients in the range of 27 µSV-80 µSV; less with i-CAT FLX. Infrequently, do we prescribe a full field of view (FOV) scan at any high resolution or with a long scan time. Such low-dose scans are typically less than full mouth dental X-rays.3 The i-CAT data set equips the clinician to focus on the patient’s individual needs and identify the appropriate imaging parameters, such as whether to capture a limited field of view (FOV) 8 x 8 or 16 x 8, or a single arch or region, versus a full-volume scan. 3D panorals are undistorted4 and make a significant difference, so 81% less errors occur compared to 2D panorals.5 We can focus on an impacted tooth with less radiation. If we are evaluating the airway and/or obstructive conditions, this requires moderate FOV pharyngeal anatomic information with certain specific volumetrics utilizing i-CAT, Anatomage, and/or Dolphin 3D software for computations and assessment, which 2D X-rays do not provide.

Low-dose 3D images Primary advantages of low dose, limited FOV CBCT are accuracy of image geometry, reliability of measurements, localization of ectopic teeth, and assessment of root resorption. While achieving quality 3D images is important, capturing scans responsibly with the lowest radiation dose possible is a priority. Clinicians must make prudent decisions about their imaging options for the best diagnostic information for their patients and practices. Practitioners can make evidencebased decisions to prescribe cone beam imaging technologies for acquiring vivid diagnostic images. Low-dose volumes are useful for tasks such as midtreatment assessment of orthodontic patients for root position and angulation within the arch. Our main diagnostic focus includes jaws, alveolar bone around teeth, TMJ, and airway. 3D renderings are the “steak,” not just the “sizzle.” Daily ambient radiation equals 8 microsieverts (4-7 days in the sun).3 Dental fullmouth X-rays are about 150 µSv and more

Second opinions We welcome other opinions, so patients can compare our 3D technology and knowledge base to colleagues. Being “smart” is believing half of what you hear; “brilliant” is knowing which half to believe. Patients become inspired and enthusiastic about treatment with us as they perceive our 3D strengths, which set our practice apart from the competition.

Patients immediately discover and experience the difference between our depth of analysis and information, compared to the quick screening cursory orthodontic exam that occurs in many offices. Often, we treat the outliers — the patients with abnormal conditions. After patients have gone to other doctors seeking an opinion, we regularly find undiagnosed problems in our 3D scan after thorough new patient evaluation. Patients value this. Once we discover the complete situation and analyze diagnostics, we can explain and visualize findings with the patient, report back to colleagues, and co-manage these conditions. We outline a course of effective and efficient orthodontic therapy for each challenging case and make it clinically navigate/flow well.
asymmetric craniofacial structural etiology. Treatment progress and therapeutic changes can be measured and viewed by visualizing, evaluating, and comparing maxillo-mandibular structures. CBCT in orthodontics equips clinicians regarding problems with erupting teeth, facial asymmetry, craniofacial anomalies, temporomandibular joint (TMJ) disorders, airway obstruction, TAD strategies, and root resorption.
CBCT data and anatomic cranial base superimposition areas make it possible to visualize and specify Class II and Class III
Cone beam DICOM imaging data and 3D renderings provide exceptional information and exquisite 3D images revealing the craniofacial structures and the malocclusions we treat. Treatment changes and comparatives can be truly captured, created, viewed, measured, analyzed, and convincingly visualized. If a treatment challenge is not going according to plan, we can scan to identify and specify why, and then modify our clinical approach.

radiation than a low-dose CBCT scan.3,6 I recommend to keep a 2D ceph and panoral unit for routine orthodontic situations. For our new patients, 2D digital screening images are prescribed for 25%, and 3D CBCT scan for 75%. Of our scans captured, 90% are 5-second scans, and 10% are 9-second or other scans.
TECHNOLOGY Discovery and visualization i-CAT imaging allows us to see true clinical anatomy that would not be visible with 2D imaging. In the TMJ region, this includes pathosis, undiscovered fractures, and degenerative conditions. We have found lesions or tumors in the airway and sinuses that extend into the cranial base of the skull and put life at risk. Some frustrated patients have visited multiple doctors with a problem. From the cone beam scan, we have discovered the issues that allowed the specialist to understand the etiology of an abnormal condition. We can help identify and co-manage these conditions. Tumors in jaws and cysts around teeth must be treated first, before orthodontics can begin. 3D imaging helps me outline a course of orthodontics for the challenging case, and so therapy navigates well.
of our practice, and teaching about radiation exposure is a priority. We don’t wait for patients to ask. We educate them before an image is taken. We explain and demonstrate the FOV and scan resolution we select as best and safe for individual needs. We explain by comparing the radiation from a scan to the everyday environment, like an extended airplane flight or weekly ambient radiation, which typically is more than one low-dose limited FOV scan. 3D users must be ready to inform our peers about radiation comparisons as well. If another colleague says that the panoramic image is good enough, we must know deeply about 3D imaging to explain the difference between radiation and distortion from a 2D

Airway issues Regarding 3D airway and sleep-disordered breathing or obstructive pharyngeal conditions, clinicians can do harm by doing nothing. “Nobody ever died from crooked teeth” — say that to the man who fell asleep at the wheel. Some ENT and sleep doctors tell patients that what we identify on our i-CAT CBCT scans is what they primarily trust and rely upon. This has helped immensely to improve our clinical effectiveness, best patient care, and referral relationships. Nasal breathers have greater airway volumes.7 RME maxillary orthopedic growth modification is effective for increasing nasal airflow.8 The oropharynx and nasopharynx volumes of Class II subjects are significantly lower than other groups.9
Education and communication Patient education is an important part

Concluding remarks When considering the safety zone of X-ray exposure, it helps to compare to our ambient exposure of 8µSv per day. The radiation exposure for a round-trip flight from San Francisco to New York is approximately 72µSv, about equal to one CBCT scan.10 We do not disregard any risk of dental X-rays. However, when we discuss the move in orthodontic imaging from traditional pan/ceph to CBCT cone beam volumetric tomography (CBVT), there should not be disagreement about exposure risk. The risks of medical imaging at effective doses below 50,000 microsieverts for single procedures are too low to be detectable and maybe nonexistent.11 50 Orthodontic practice

i-CAT is known for its low-dose radiation, a fact appreciated by patients. The diagnostic benefits of CBCT have been clearly substantiated by research and clinical circumstances. A primary benefit of CBCT is in seeing the anatomic truth. You don’t know what you can’t see. How else can you visualize airway, TMJs, transverse relationships, buccal-lingual widths of bone, and teeth/root positions all in one simple low-dose scan? There is no comparison.12 The transformation of my clinical practice with i-CAT CBCT 3D is extraordinary. Imaging goals and CBCT protocol seek answers to specific clinical questions utilizing a precise and exquisite display of relevant anatomical representation. Individualized patient findings are closely analyzed by the clinician. Each of us has huge capacity to continuously learn and achieve to become brighter and better. One is not a successful clinician until fullest efforts have been made to become the best one can be in providing the finest individualized patient care. The future is now. Together, we lead the way with i-CAT cone beam and related technologies in modern orthodontic practice. Stay out in front — the lead dog has the best view in the race. See you at the top! OP

Cloud computing in orthodontics Jake Gulick discusses how cloud computing can benefit an orthodontic practice
What is cloud computing? If you visit any technology-related website section these days, you are bound to see articles about â€œthe cloud.â€? The cloud is a very fast-growing technology, and many people do not realize they have been using the cloud
Jake Gulick has been with Cloud9Ortho for 3 years and has worked in the orthodontic technology sector for over 7 years. He started as a trainer for Cloud9Ortho and has seen firsthand how cloud computing can change an orthodontic practice. He graduated from The University of Iowa with a BBA in Marketing.

in their daily lives and office for years. Email clients, such as Gmail and Yahoo, are cloudbased. The easiest way to explain the cloud is that the data is available 24/7/365, and the information is not stored on your device. Instead, the data is stored in a data center, sometimes thousands of miles away. Cloud computing is not a new concept even in the orthodontic world. Companies such as TeleVox and Sesame have been providing cloud services to offices for many years. They make the phone calls and send emails from a data center, not from your office. They also allow patients to access
information about their appointments and financial balance from any computer. The patient is logging into the cloud when using one of these systems.
Why is the cloud growing so fast? A big reason is the number of companies investing in the cloud. For example, Dell Computers, whose core business had been selling computer hardware, has invested over $1 billion in data centers. IBM has also been aggressively investing in the cloud by spending over $3 billion acquiring cloudbased companies. Orthodontic practice 51
PRACTICE MANAGEMENT Over the last 5 years, we have seen a huge shift in the services being offered by companies such as Microsoft, Amazon, and Apple. Microsoft 365 is the office suite built on the cloud. Amazon has many cloud applications, including Amazon Cloud to store music and files. Apple has expanded iCloud to allow sharing across all of your iOS devices and Apple computers. Cloud computing is making our lives simpler by allowing us to access our data anytime, anywhere, from any device. With the explosion of smartphones and tablets, the demand for cloud services has erupted.
How does cloud computing fit into your practice? As mentioned previously, you are probably already using it for email or patient communication, but over the last several years, we have seen cloud practice management software enter the orthodontic world. Not all clouds are created equal, so make sure you research each option and understand the different platforms.
How can it help your practice? By moving your practice to the cloud, you will have much more freedom with your practice. If it is a web-based application built from the ground up, you will be able to run your practice from any computer, PC or Mac, in its native mode and without installing any software. You will no longer need a server in the office as all data is stored in real time in the cloud. Your IT cost would be reduced since there is no longer an expensive server to buy or maintain, and your connection costs should be reduced significantly. You will not have “satellite” offices any more since every office will run exactly like your main office. Images will be lighting fast in all offices as well. The use of remote desktop, Terminal Services, LogMeIn, or other old technology will be eliminated. You also will no longer need to worry about backups of your data or imaging as those would all be taken care of for you! Imagine having a laptop fail in your clinic and being able to go to Best Buy or connect to Amazon.com, order a new laptop, plug it in, and be using your software without calling your IT company or even your software company. That is the power of the cloud!
What are the concerns regarding cloud computing? The biggest worry about the cloud is 52 Orthodontic practice
Cloud computing is making our lives simpler by allowing us to access our data anytime, anywhere, from any device.
about the security of your data. Think of this way — do you keep your money in your house under your couch or in a bank where it is secure? Think of your patient data the same way. Is it safer in your office where someone could break in and steal your server, or a data center with armed security? If you were using a cloud system and someone broke into your office, there is no server or data to steal since it is all stored offsite. “Cloud computing is often far more secure than traditional computing, because companies like Google and Amazon can attract and retain cyber-security personnel of a higher quality than many governmental agencies,” said Vivek Kundra, former federal CIO of the United States.
What if the Internet connection goes down? The Internet is only getting better and more stable by the day. I do not remember the last time my Internet was down. The broadband Internet connections from mobile carriers like Verizon and AT&T are getting huge boosts in speed. If you are concerned with losing your local Internet connection, you can pay $50 per month for a backup HotSpot for your practice or have a backup DSL connection. Chances are you will never use it, but for peace of mind, some may find it comforting.
What should you ask a cloud provider? As much as cloud computing can help your practice, if you are not careful, you can also be misled by “cloud washing,” which is “the purposeful and sometimes deceptive attempt by a vendor to rebrand an old product or service by associating the buzzword ‘cloud’ with it.” This is not just happening in orthodontics but across all industries. When looking into a cloud practice management software, be sure to ask if it was built as a web-based application. Many times, companies will just move your server offsite, host your data for you, and call it “cloud.” David Linthicum, a cloud computing expert with InfoWorld, says, “Truth be told, most of those presentations are given by salespeople who don’t know a cloud from a hole in the ground; they actually believe what they’re selling is a cloud.”
Bottom line A cloud-based practice management software can be a great addition to your practice and allow you the freedom you have only dreamed about before, but before you jump in with both feet, make sure you ask the right questions and move to an application that was designed from scratch to operate in the cloud. Only then will you achieve the full benefits of a cloud application. OP

A unique approach to ceramic brackets for organic practice growth Dr. Paul Tran explores the advantages of ceramic brackets
s orthodontists, we often think of esthetics as a final result — a patient comes in with malaligned teeth, and we give them a beautiful smile at the end of treatment. However, I will be the first to admit that as orthodontists, we don’t always pay close enough attention to the treatment process in its entirety. In order to achieve a successful esthetic result, we must focus on esthetics during the complete treatment journey, from the tools and materials we utilize to the brackets themselves. While my practice still offers metal brackets, we have successfully adopted esthetic brackets and are quickly moving toward becoming a practice that exclusively offers esthetic options to our patients. We have developed a unique concept for approaching the choice between metal and ceramic, and from a practice growth standpoint, it has proven to be one of the best moves we’ve ever made. I’d like to share with you how we accomplished this and provide tips on how to effectively make this transition with both your adult and teen patients.
In the beginning When I began practicing in the orthodontic field 20 years ago, I primarily used metal brackets and treated only a select few adult patients with ceramic brackets. At the time, ceramic brackets were not as efficient — they were harder to debond, bulky, and shattered frequently. Like many of my colleagues, I tried to talk my patients out of ceramic brackets because I didn’t feel that they offered an effective solution. Paul Tran, DDS, MSD, was born in Hong Kong, China, and grew up in Brazil. While residing in those countries, Dr. Tran learned to speak Chinese and Portuguese fluently. Dr. Tran attended the University of Houston for his undergraduate degree, his DDS degree in 1990 from the Baylor College of Dentistry, and his Orthodontic Certificate and MSD in 1994 from the University of Kentucky. He started Tran Orthodontics in 1995 and now practices in Middletown and Prospect, Kentucky. He has served in many capacities in organized dentistry such as president of the Kentucky Association of Orthodontists and a delegate to the American Association of Orthodontists. Over the past 20 years, Dr. Tran has spent countless hours learning from the very best in dentistry and orthodontics and is also an alumnus of the prestigious McLaughlin Program.

Figures 1 and 2: Ceramic bracket systems such as Clarity™ ADVANCED Ceramic Brackets from 3M Unitek (top) offer a more discreet and esthetic treatment option compared to metal brackets (right)
When clear aligners came into the market about 15 years ago, they were heavily promoted throughout the orthodontic world. We saw the market respond to the promotions, and patients began to ask for clear aligners. While we initially treated patients with clear aligners to meet this growing demand, we recognized that traditional braces were more effective, easier to maintain, and achieved the best final result. As demand grew for clear aligners, it became obvious that there was a fervent need for esthetic solutions. When we were introduced to ceramic systems such as Clarity™ Metal-Reinforced Ceramic Brackets from 3M Unitek, it was clear that this was a completely advanced product. The quality, ease of debonding, strength, and durability of these ceramic brackets were so impressive that we decided to use 3M Clarity brackets with the majority of our patients. Ceramic brackets became our solution to meet the growing demand for esthetic products and gave our patients the superior smiles we both desired. To be clear — clinically, ceramic brackets are no different than traditional metal brackets. There is no learning curve when making the transition, and in my experience,
debonding is considerably easier. I now work with Clarity™ ADVANCED Ceramic Brackets from 3M Unitek and have had excellent results. If you can use a metal bracket on a patient, you can also use a ceramic bracket.
A unique perspective on pricing When we began the transition toward an almost exclusive ceramic practice, we made a major decision that has set us apart from other practices: We decided that whether a patient wanted metal or ceramic, we would charge the same fee. How is this possible? Even though ceramic brackets have a higher initial cost compared to metal brackets, our office overhead never changed significantly. However, the benefits we saw were an increase in new patients seeking esthetic solutions, and that itself more than made up for the cost difference, especially when spread over a number of patients every month. For our patients, removing cost concerns from the equation eliminated the difficult part Volume 5 Number 6
metal bracket on a patient’s upper arch (not including molar brackets). Since transitioning to ceramic brackets and offering a level playing field in terms of associated costs to our patients, we have seen incredible growth in our practice. We believe that this is attributable directly to the superior esthetics we’re offering, and the fact that our patients aren’t afraid to talk about it. Referrals and word of mouth are indispensable in creating a solid reputation and a steady patient stream.
Esthetic solutions for the younger crowd
Figure 3: Colored ties can easily be removed from ceramic brackets for younger patients’ important life moments such as their first day of school or family pictures
Figure 4: For younger patients, the Paint Your Smile tool from 3M Unitek at paintyoursmile.com allows them to see firsthand how the colored elastic ties will “pop” with ceramic brackets
When the fee scale is equal, adults don’t generally need any additional encouragement to opt for ceramic brackets. Younger patients, however, have different priorities, and sometimes require us to take extra time to explain why we recommend clear brackets, since most of their friends are still wearing traditional metal braces and they want to “fit in.” I begin conversations with my younger patients and their parents by discussing major life moments. Transitioning into high school is a big step for the majority of them (Figure 3). We want them to be able to laugh and smile without being self-conscious about their braces on the first day of school. We discuss color options, and they’re usually amazed when they see how much the colored elastic ties “pop” on a ceramic bracket (Figure 4). We always tell their parents that the beauty of ceramic brackets is that the colored bands can always be replaced with clear for important milestones or pictures. A great resource we have used for younger patients is the Paint Your Smile tool from 3M Unitek at paintyoursmile.com. This website allows us to upload a “selfie” of the patient and show them what their ceramic braces will look like compared to
Figure 5: From the initial consultation to the final office visit, it’s important to give first-class service and treatment to every patient who walks through the door Volume 5 Number 6
traditional metal braces. The website lets them test-drive different colored bands on their braces before committing to a treatment option. Giving younger patients this type of platform to create their own smile gives them some independence when coming in with their parents.
The take-aways If you see the advantage in transitioning to ceramic brackets in your practice, it’s important to be prepared to position this esthetic solution as a value-add to your patients and clearly communicate the benefits. While it’s not always as easy as a patient walking in and asking, “Can I have ceramic brackets?”— when the patients understand what they will gain from a truly esthetic treatment plan, their experience is instantly elevated (Figure 5). For me, there are three things that have been most important in making this a successful transition: 1. Thinking creatively — By implementing an equal pay scale for traditional metal and ceramic brackets, we help our patients enjoy outstanding results and, at the same time, grow the practice and establish a positive reputation in our community. 2. Training staff — In order to get buy-in from your patients, your staff has to be educated about the benefits and fully committed to furthering the goal. 3. Utilizing resources — You are not alone in wanting to make a positive change in your practice. I rely heavily on my 3M Unitek sales representatives to field my questions, help brainstorm new ideas for marketing, and collaborate on how to best communicate product benefits. As orthodontists, it’s our duty to offer the best possible solutions for our patients, and in my opinion, ceramic brackets help me to accomplish this every day (Figure 6). OP

of their decision process, and now they overwhelmingly choose ceramic brackets for their treatment. For our practice, we receive a greater benefit from being perceived as a top-notch esthetic practice with happy patients than we would from pinching a few pennies.

Generating more new case starts through topical search Diana P. Friedman explores how consumers search for online information
hen consumers, including prospective orthodontic patients, head to the Internet, 93% start by initiating a search.1 Healthcare continues to be a topic of great interest, as 72% of Internet users look online for health information.2 However, where consumers conduct their searches is undergoing a dramatic shift. Welcome to the world of topical search — websites or portals that cater to a specific topic or area of interest. Though the term topical search may be new, websites that cater to highly targeted search results have been around for a long time and are gaining significant traction. A recent study found that topical search sites experienced an 8% increase in search traffic while major search engine traffic decreased by 3% over the same period.3 Some great examples of successful consumer topical websites include WebMD, Amazon, and eBay. Healthgrades.com is the best example of a dental and orthodontic topical search site and is the most influential when it comes to searching and evaluating healthcare providers. More than 225 million visitors use the Healthgrades.com website each year to connect with healthcare providers that best meet their treatment needs. An amazing 20-plus million of these prospective patients search Healthgrades.com for a new dental care provider in their local area (including searches for an orthodontist). More compelling is the demographics of Healthgrades. com visitors — overwhelmingly female (72%), highly educated (84% have some postsecondary education), and affluent (52% have annual household incomes greater than $75,000). Not only are these demographics ideal for orthodontics, the behavior of prospective patients using Healthgrades.com goes far beyond just looking for health information

Establishing a predictable stream of new case starts remains a key driver of practice growth and profitability. — research shows more than half of visitors (54%) will schedule an appointment with a provider. Of this large group of prospective patients, an astounding 38% of them schedule the same day they visit, and 95% make an appointment within a week. It’s clear that Healthgrades visitors conducting topical searches are an ideal target audience for growth-minded orthodontists. Topical search sites such as Healthgrades are changing the way prospective patients find your practice. So how can you take advantage of this to drive more new case starts? Let’s examine the construct of the Healthgrades topical search site to find the answer.
Healthgrades: two profile types Basic A Basic Profile is already available and practitioners can “claim” it for free. It includes limited information about your orthodontic practice such as name and address. These profiles include third-party and competitive practice advertisements and do not provide visitors with a way to schedule an appointment with your practice. Any Healthgrades visitor can submit a review of your practice, but they are not verified as your patients. So while you do want to claim your Basic Profile to ensure your provider information is accurate, the ability to gain case starts through the visibility afforded in having a top ranking for your location, or convert visitors into patients, is severely limited. Enhanced Late last year, Healthgrades Enhanced Profiles were introduced to the dental
industry through a new partnership between Healthgrades and Sesame Communications. The Enhanced Profile provides your practice with a multitude of benefits over the Basic Profile and is the best way to turn your share of the 20 million prospective patients searching for a dentist or orthodontist into new patient appointments. The major benefits of an Enhanced Profile on the Healthgrades.com topical search site include the following: Automatic publishing of verified patient reviews — With a Healthgrades Enhanced Profile, verified, and high-quality postappointment surveys from Ortho Sesame are automatically published to your Healthgrades Enhanced Profile. This ensures that the vast majority of patient reviews are verified and represent the true value your practice delivers. It also helps prospective orthodontic patients have confidence that the review ratings are accurate and credible. Priority positioning in local search results on Healthgrades.com — An Enhanced Profile gives your practice higher placement in search results and greater visibility to patients searching for an orthodontist in your area. It provides premium postings in their “Featured Provider” section in addition to your inclusion in organic search results. On average, a visitor to Healthgrades.com will view 1.9 profiles during their visit, so it is imperative that your practice be featured prominently in the search results. Only Enhanced Profiles can show up in both featured and organic search results. Front page calls to action — Enhanced Profiles allow patients to easily schedule an appointment with your practice by providing front page access to your practice phone number, a “Request an Appointment” link, and a link to your practice website. With one click on your Healthgrades Profile, a prospective patient can easily schedule that first appointment. This easy access helps facilitate more appointment requests for your practice.

practice’s Healthgrades Enhanced Profile. The analysis showed that practices generated, on average, more than 11 calls during a 4-week period after the initial launch of their Enhanced Profile. The study analyzed the volume of incoming calls received by 98 dental and orthodontic practices with Healthgrades Enhanced Profiles from Sesame during the time period between December 9, 2013, and January 25, 2014, and in addition to the average of 11.1 calls received, also found that: • Practices, on average, had 21.33 postappointment reviews automatically published from Dental Sesame or Ortho Sesame. • Of practices with Dental Sesame or Ortho Sesame and a Healthgrades Enhanced Profile, 94.12% showed up on page 1 of local organic search results on Healthgrades.com, in addition to their Featured Provider listing.
highly targeted, and qualified set of prospective patients looking to make an appointment with a provider in your local area. Establishing a predictable stream of new case starts remains a key driver of practice growth and profitability. While many practices have rightfully embraced other digital marketing strategies to attract these new patients, they have yet to adopt a systematic method of success where reviews are concerned. With increased traffic on topical sites and performance percentages like this, it’s time to utilize this new channel as a primary source of new patients. OP
