When it relates to kids, the medium is the message

T

here’s been a lot of talk about the power of social media and the role it can play in building your practice. As a true believer in social media, I can tell you that this is 100% true. Without a doubt, the efforts my staff and I put into social media have been rewarded many times over in the building of our practice in the Greater Toronto Area. In fact, social media comprises a significant portion of our marketing. But most importantly, even if there was no financial reward for these efforts, they would still be one of the most essential tools at our disposal. Let me explain. Everyone who’s drawn to this profession has a passion for Dr. Ajeet Ghumman working with children. The experience is the reward. We’re not just helping children look better in their selfies and senior portraits. We’re changing the way they think of themselves and how they embrace the adult world, a task that’s hard enough without feeling insecure about your smile. The thing that’s so important, and so often overlooked about social media is that it’s not just a vehicle for communicating with today’s plugged-in preteens and teens. It’s the actual language they speak. Marshall McLuhan coined the phrase “the medium is the message” back in the 1960s. Four decades before the idea of social media was even invented, he understood that the actual form of the communication carried as much impact as the communication itself. He believed that “content” was nothing more than “a juicy piece of meat carried by the burglar to distract the watchdog of the mind.” The Dental Works 4 Kids practice has thousands of posts, tweets, and images out there. While it’s wonderful to recognize patients that get their braces off or celebrate the latest big win by our hometown Toronto Blue Jays, in a lot of ways, the medium is just as important. Every kid that reaches a certain age becomes a bit of a skeptic. And this is a good thing! It means they’re becoming independent, and they’re preparing for a world that doesn’t always have their best interests in mind. The flip side is that it can make it difficult for an adult to reach them, even when he/she has the teen’s best interest in mind. This is precisely why social media is so invaluable. When you’re on the social channels, you’re not just meeting kids on their own turf — you’re doing so in their own language. This has the wonderful effect of allowing you and your message to slip past their natural skepticism filter, allowing them to weigh the significance of what you’re saying without having to win them over. I’m sure you don’t need to be told the value of this. Social media is a great way to build a practice, but it’s an even better way to build a rapport, and that’s the real value. Dr. Ajeet Ghumman

INTRODUCTION

November/December 2015 - Volume 6 Number 6


MESSAGE FROM THE PUBLISHER

When inspiration meets reality Dear Readers: With this issue of Orthodontic Practice US, I am delighted to introduce a new series of articles that have the potential to change the course of your life. I know this to be true because over the years, the author of these articles, Tony Robbins, has impacted me both professionally and personally. This story begins when I was in my 20s. At that time, life’s challenges were daunting, and the road ahead seemed not only to be winding, but filled with potholes and roadblocks. Also, I was searching for a career path that would also be my life’s passion. It was then I discovered peak performance strategist and bestselling author Tony Robbins. Listening to his motivational tapes in my car on the way to and from work was often the only positive voice that I would hear all day. “Human beings have the awesome ability to take any experience of their lives and create a meaning that disempowers them or one that can literally save their lives.” His insights catapulted me to achievement of my professional aspirations, as well as personal fulfillment. I remember wishing that I could attend one of Tony’s seminars in person. Fast-forward 25 years later. As a successful publisher and entrepreneur, I had the opportunity to attend CEREC® 30, an educational event sponsored by one of our long-term clients, Sirona Dental, Inc. I was beyond excited that Tony was going to be a featured speaker at this event! It was a surreal moment when I had the opportunity to stand up in front of upwards of 6,000 attendees and ask a question of my mentor, Tony Robbins, peak performance strategist and bestselling author, who wasn’t even aware of the impression he had made on me over the years. It was with Lisa Moler, publisher and CEO of MedMark, LLC, at CEREC 30 even more incredible when he was gracious enough to schedule a personal interview with MedMark for our magazines. This brings me to good news for our readers. I am so proud and honored that Tony Robbins and Tom Zgainer, founder and CEO of America’s Best 401k, will be authoring a Financial Focus column for our publications in 2016. This column will discuss what to look for in a 401k plan, show how fees can erode 401k savings, and will also discuss the fiduciary responsibility of plan sponsors and the serious ramifications of non-compliance with The Employee Retirement Income Security Act of 1974 (ERISA). This federal law sets minimum standards for most voluntarily established pension and health plans in private industry to — Tony Robbins provide protection for individuals in these plans. Sadly, many plan sponsors do not live up to their duties, and as a result, the savings of all the participants in their plan may be subjected to needless and excessive fees. Tony said, “The abuse is mind-boggling.” At MedMark, we pride ourselves on educating the dental community on new techniques, the latest products, and creative practice management methods. Now, Tony Robbins and Tom Zgainer will share their expertise to protect and help grow your retirement savings. At our interview, Tony Robbins and I discussed living in the moment and letting go of the ghosts of the past. He once said, “In life, you need either inspiration or desperation.” It was in times of desperation that I found inspiration in his powerful insights. Now, I am honored that it’s my turn to be a catalyst, through this new Financial Focus column, for our readers to have more control over their financial success in retirement. All the best,

“In life, you need either inspiration or desperation.”

oversight, which has become more aggressive in recent months,” Zgainer said. Robbins adds, “Small business owners often have no idea that they are the fiduciaries for their plan. That means that they have to benchmark that plan annually or they have to pay penalties, with average penalties that can reach $600,000. We can help these people meet their responsibilities in this area.” In as little as 60 seconds, dentists and other business owners can access the company’s free Fee Checker (americas best401k.com/medmark), which can help them meet their fiduciary obligation and ensure their retirement plans are for the sole benefit of their employees. When a dentist sponsors a retirement plan, he/she takes on new responsibilities in addition to being a doctor and a business owner. They also need to meet their fiduciary obligation and fulfill their trustee responsibility. Robbins and Zgainer’s advice can lead to employees keeping more of what they’ve saved, and enjoying a longer, more-secure retirement. America’s Best 401k has assembled a team of world-class retirement plan experts across design, administration, recordkeeping, and actuarial disciplines to offer an alternative to expensive, complex plans. Working with America’s Best, business owners can alleviate their fiduciary responsibility while providing their employees with a plan that doesn’t sacrifice performance for lower fees. For information, contact America’s Best 401k at 855-905-4015 or info@americas best401k.com. Readers of Orthodontic Practice US will be able to share more of this exciting and informative conversation with Robbins and Zgainer through a series of interview articles that will appear in upcoming issues.

PRACTICE PROFILE

Michael Bicknell, DDS, MS His social, scientific, and artistic life

I

t’s a rather simple formula for Dr. Mike Bicknell of Advanced Orthodontic Specialists in Elmhurst, Illinois — work hard, treat people with kindness and honesty, and you’ll build and maintain a successful orthodontic practice. Serving a tight-knit suburb of Chicago, Dr. Bicknell runs an esteemed practice founded on bringing the highest quality of care and service to his patients. In this issue, we’re getting to know Dr. Bicknell — from what makes his practice stand out to what profession he would pursue if he wasn’t an orthodontist.

What can you tell us about your background, and why you decided to become an orthodontist? I grew up in a small suburb of Chicago where my mom was a nurse and my dad was an accountant. My parents stressed the value of education to my siblings and me and, subsequently, the importance of hard work. I went to an all-boys Catholic high school, and for our senior year project, we were tasked with giving a presentation on what profession we’d like to pursue. I had a great relationship with my dentist growing up, so I did a little research Dr. Bicknell’s practice is located in a tight-knit suburb of Chicago and gave my presentation on becoming an oral surgeon.

PRACTICE PROFILE Who has inspired you? First and foremost, my parents have been incredible influences in my life. My core — what I believe, and how I treat people — was developed based on how they raised me. My inspiration also comes from my junior high school science teacher who also happened to be my wrestling coach. He had a lot of character and passion for what he did, and carried himself with confidence and wasn’t afraid to be his own person. Professionally, to this day, I look up to Dr. Kevin Kopp, a prosthodontist in my area, who centers his whole practice on patients, and I love that. He has a great practice model that is very admirable. As far as orthodontists, there are countless professionals who have inspired me. To name a few, Dr. David Sarver is extremely insightful, Dr. Dwight Damon operates with unmatched passion, and Dr. Stuart Frost creates exceptional smiles with signature smile arcs.

Dr. Bicknell notes that his office staff is like an “extension of his family”

What is the most satisfying aspect of your practice, and what makes it unique? The most satisfying thing about my practice and profession is that it is a reflection of every aspect of my personality, which makes my job so enjoyable — it’s social, scientific, and artistic. It’s also comforting and satisfying knowing that we are taking care of people and helping make their lives better. At my practice, we place a significant emphasis on engaging with the surrounding community and, more importantly, giving back to it. We’ve hosted a holiday season toy drive for the past several years, and have donated more than $150,000 in treatment to

local schools. We also supply mouth guards for youth football programs in the area. It’s truly a win-win.

Professionally, what are you most proud of? This is by all means a joke, but I’m really proud of the fact that I give away T-shirts with our practice logo on them, and patients actually wear them! I like to think that we’ve officially “made it” now that we have a T-shirt with our name on it. My staff and I joke about this all the time because it’s such a trivial part of our practice, but I admittedly spent quite a bit of time designing the shirt. In all seriousness though, I’m proud of the fact that I consider my staff an extension of my family, and that we all share similar values: to be hardworking and kind. Being able to work in such a great, close community is also something I’m proud of and truly grateful for.

What is the future of orthodontics? The future of orthodontics is interesting because I think there are some negative perceptions lingering around the industry right now and where it is headed. That said, I feel the opposite. I’m positive about what the future holds for orthodontics. While it’s hard to predict what the future will look like for the industry, I do know that as technology 14 Orthodontic practice

Water — I love living by Lake Michigan; I can go to the beach or go boating whenever. 4. Steak! 5. A project — I like to always be working on something and learning new things.

continues to evolve, so will orthodontic products and solutions. Think of it this way; 30 years ago, do you think anybody believed that one day orthodontic manufacturers would be selling digital intraoral scanners that create digital impressions in just minutes? Probably not. Regardless of what the future may or may not hold, I believe that if orthodontists continue to lead patient-centric practices, we will be successful. Techniques and technologies may change, but the fundamentals of how you treat patients and the quality of customer service you provide should remain constant at the highest level possible.

What advice would you give to budding orthodontists? More than anything, I like to encourage orthodontic residents and those interested in orthodontics to provide their customers with the highest quality of care possible. I believe that if you are kind, honest, and work really hard, you will be successful. What’s great about this sentiment is that it applies to just about any profession. Meet your challenges head-on too — don’t shy away from them. With hard work and dedication, you can be the best. Additionally, it’s imperative that you never stop learning — orthodontics is a

lifelong learning process. Even when you think you’ve perfected a specific technique or mastered your practice marketing, know that there is always something more to learn. Embrace this reality because at the end of the day, it will make you a much better practitioner.

What are your hobbies, and what do you do in your spare time? I’m very family oriented, so anything that I can do with my wife and three kids is ideal. My wife and I have been into skiing quite a bit lately and actually introduced it to our kids too. We are also big fans of taking family boat trips. We live right near Lake Michigan, so on the weekends, if the weather is right, we’ll take the kids out on the boat and explore different harboring towns.

What would you have been if you had not become an orthodontist? I like this question! I would probably be a fighter pilot or astronaut, but the kind of astronaut that actually gets to go to space. A blockbuster actor would be pretty cool too. I say all these things with a sense of humor because I truly would not want to be doing anything other than what I’m doing right now. I absolutely love my job and wouldn’t trade it for any other profession. OP Volume 6 Number 6

CASE STUDY

Integrating innovative technology to meet patient deadlines Dr. Gary W. Chu said “I do” to speeding up a patient’s orthodontic treatment for her wedding day

F

ive years ago, if a bride-to-be had come to my orthodontic practice requesting to start and complete her treatment prior to her wedding that was less than a year away, it was highly unlikely that neither I nor any other orthodontist could safely and effectively make that request a reality. In fact, over the years, orthodontists have consistently been challenged to meet patients’ deadlines because the field simply didn’t have the technology and innovation to do so without the use of drugs or invasive surgery. Today, however, with the advancements that are happening as a result of the emergence of accelerated orthodontics, I am able to give patients healthy, beautiful smiles just in time for their weddings, graduations, or other special deadlines. At my practice, Chu Crew Orthodontics in Racine, Wisconsin, we offer patients

AcceleDent®, an FDA-cleared, Class II medical device that speeds up treatment by as much as 50% and relieves the discomfort associated with wire adjustments. Therefore, when a soon-to-be bride walked into my practice in the fall of 2013, I was confident that we could help her achieve the smile she wanted in time for her big day, which was just 9 months away. She was one of my first AcceleDent patients, and I was extremely pleased with the results and thought it would be beneficial to share this case with my peers. The 24-year-old patient presented in September 2013 with Class II, Division I malocclusion which specifically included 12 mm of significant crowding in the lower arch, a buccal crossbite between tooth No. 5 and tooth No. 28, and a complaint of protruding canines. Her overbite was 80%

and overjet was 2 mm. She had a deep curve of Spee, and her upper midline was 0.5 mm to the left. Adding to the complexities of her malocclusion, the bride was an adult patient which makes tooth movement more difficult due to the fact that bone remodeling in orthodontics is markedly reduced in the adult population. I remember clearly this patient telling me that she wanted to look the best she possibly could for her wedding pictures. That resonated with me from the very beginning, which is why I offered her AcceleDent. I was confident that with this innovative technology we could reduce her projected 18-month treatment time to 9 months.

Light forces and minimum friction I felt confident that I could help her meet her deadline primarily because of the

AcceleDent technology and also because my treatment plan included the Damon® Q™ fixed appliance bracket system. I knew that the Damon Q brackets in conjunction with AcceleDent would deliver the optimal movements and light forces that I’ve found effective with my patients. In my opinion, the Damon System is superior because it utilizes light forces and passively allows archwires to slide through the bracket slot. As a result, the brackets promote biocompatible movement, which leads to far more comfortable and efficient treatment. I’ve been intrigued by the technology behind AcceleDent since it was being Volume 6 Number 6

evaluated in clinical trials. Having attended dental school at the University of Texas at San Antonio, I knew how reputable and forward thinking the university’s research was at my alma mater. Prior to its recent publication in Seminars in Orthodontics,1 I reviewed Dr. Dubravko Pavlin’s randomized controlled trial that demonstrated how pulsatile forces significantly accelerate tooth movement. I flew down to Houston to meet with the OrthoAccel executives to ensure that I would be one of the first orthodontists in the country to offer this innovative technology in my practice. Dr. Pavlin’s research not only explained how SoftPulse

Technology® could accelerate my patients’ orthodontic treatment, but also convinced me that AcceleDent is safe and gentle.

50% reduction: 18-month treatment completed in 9 months In this particular case, the patient was on board, committed to my treatment plan, and bonded in October 2013. I typically change wires at 10-week intervals with Damon brackets, but with AcceleDent, I discovered that I was able to change her wires every 5 weeks. Treatment began with a .014 Nitinol wire to engage tooth movement; this wire Orthodontic practice 21


CASE STUDY is essentially a wake-up call for the tissues. I extended the .014 wire through the first molars because extending it further posteriorly could have created a situation where the wire might come out while the patient was eating. When I progressed to the .018 Nitinol wire, I extended that through the second molars. The third molars were not addressed during treatment at the patient’s request. The .014 x .025 Nitinol was the first rectangular wire I used with this patient, and it began the development of the arches and initiated root alignment. Typically, it is critical to leave this wire in for 10 weeks, but again, I was happy with tooth movement after just 5 weeks with AcceleDent. The .018 x .025 Nitinol was the largest Nitinol wire we used, and it achieved the majority of the arch form and root alignment that I look for in all my

finished cases. The .018 x .025 Nitinol was again used for 5 weeks instead of the 10 weeks that is typical with standard treatment. The final wire was the .016 x .025 TMA, which allowed for any remaining corrections following the rectangular Nitinol wires. Perhaps one of the greatest benefits of the accelerated treatment with AcceleDent is arriving at final wires with ample time to apply artistic bends enhancing and perfecting a patient’s smile. In standard treatment, patients are typically burned out and impatient by the time they get to the finishing wires. However, we now get to the final wire faster with AcceleDent, and I still have time to be selective and precise with detailing the finished result.

Prior to debonding, impressions and a panorex were taken to evaluate the alignment and also check for proper function, including incisal guidance and cuspid rise. Short Class II elastics began with the .014 x .025 Nitinol wires and continued until debonding. Retention consisted of a bonded lingual 3 x 3 and upper and lower vacuum molded removable retainers. This patient was debonded in July 2014. As you can tell from her wedding photos, she had a very confident smile on her big

day. Additionally, she recalled experiencing little to no pain throughout treatment. I have to say she was the perfect patient and complied with everything that was asked of her, including using her AcceleDent for 20 minutes daily. She was obviously very motivated by her deadline, but it’s also important to note that she had a very demanding schedule as she was working full time, going to school to earn her master’s degree and, of course, planning her wedding. Accelerated treatment was especially important to her considering

that she committed to driving over half an hour to and from every visit.

Accelerated orthodontic treatment is standard of care My primary takeaway from this case is that a 9-month treatment of a Class II, Division I malocclusion case is possible because of the appliances and technology that are now available to orthodontists. AcceleDent works well with the Damon System because it enhances bone remodeling with such light forces that we are able to achieve excellent

expansion posteriorly, which means that the majority of my cases are now non-extraction. Since the Damon System allows us to keep the forces light and biologically compatible, we are not cutting off blood flow to the teeth; we are actually encouraging osteoblastic and osteoclastic activity while avoiding necrosis and microtrauma. Similarly, AcceleDent enhances that protocol because the micropulses of the device’s SoftPulse Technology® are intended to increase bone turnover in order to accelerate tooth movement. AcceleDent cycles at a frequency of 30 Hz, far less force than what is used to chew gum and 8 times less than what is emitted through a power toothbrush. Damon in conjunction with AcceleDent has become my practice’s standard of care. All of my new patients automatically receive AcceleDent, and the cost is included in the overall treatment fee. Our practice has a reputation for providing the highest quality of care to our patients, and our community has come to realize that accelerated orthodontic treatment is now a part of the care that people have come to associate with Chu Crew Orthodontics.

Watching … wondering … observing Dr. Ron Roncone discusses using Roncone PDS to have fewer appointments and shorter treatment time

W

hat if an orthodontist were to observe the same phenomenon several thousand times? The Same Input = The Same Output Would this be clinically significant? If these observations could not be found in the literature, would they be invalid? Would we NOT be practicing evidencebased orthodontics? I would like to mention just seven of the many observations I have made in 44 years of orthodontic practice. The vast majority have occurred since 1981. Since that time, I have taken tomographs or CBCT on “almost” every patient. I have taken frontal cephs (or CBCT) on “almost” every patient. Except for a 1½-year period (1976-1978), I have articulated all starts and all finished cases. I have treated more than 35,000 patients since 1974.

Figure 1: Arrows show antegonial notching

Observation 1 Antegonial notching of the mandible is evidence that there has been a long-term (years) hypertonicity of the masseter and medial pterygoid muscles (Figure 1). This will impede timely orthodontic treatment at best or cause failure at worst. Easy cases turn into difficult ones. What to do? Initiate at least 6 weeks of full-time splint therapy along with the use of ultrasound and ethyl chloride spray before orthodontics begins. Turbos on maxillary central incisors must be used as part of the treatment plan to keep muscles relaxed and avoid posterior tooth contact.

Observation 2 Close approximation of cervical vertebrae on the dorsal surface almost always Ronald Roncone, BA, DDS, MS, received his degrees in physiology from Marquette University and his postdoctoral Certificate in Orthodontics from Forsythe Dental Center and Harvard School of Dental Medicine. Dr. Roncone maintains a large practice in Vista, California, with 55% adult patients. Dr. Roncone has lectured extensively, presenting more than 1,000 seminars around the world, and is President and CEO of Roncone Orthodontics International®, which offers practice management courses as well as in-office consulting and marketing services.

Figure 2: Cervical vertebrae with no spacing

Figure 3: Maxillary asymmetry — left side lower

indicates that the mandible is in a forward position to achieve maximum occlusion. Since the average person swallows between 1,700 and 2,400 times a day, this maximum intercuspation is easier to achieve with the head in a forward position. The true occlusion is either more Class II then we see or more Class III (Figure 2).

Observation 3

What to do? If the mandible can easily be hinged to a first contact position, begin orthodontics with turbos or a banded Nance bite plate to unlock occlusion. If the mandible is not easily hinged to first contact — splint and physical therapy (PT) modalities for 6-8 weeks. This forward head position has NOTHING to do with lack of airway. With the advent of CBCT and good health history, you can be sure it is not an airway problem.

A significant majority of patients have a maxillary frontal asymmetry. This causes the mandible to grow asymmetrically as well. This causes joint problems, muscle problems, and esthetic problems. We have all seen and treated uncorrected maxillary asymmetries. We have all seen the uncomplimentary smiles where more gingival tissue is seen on one side of the arch than the opposite side — even though the teeth meet correctly (Figure 3). What to do? Place a fixed Hyrax appliance, and expand. Continue two forward turns, alternating with two backward turns for at least 6 weeks. These turns are alternated on consecutive days. The continuous swallowing (1,700 – 2,400 times daily) will assist in “leveling” the maxilla. I have observed this phenomenon for more than 35 years. Volume 6 Number 6


Just under 30% of children between the ages of 10 and 16 have some evidence of condylar degenerative joint disease (DJD). Most of this does not coincide with past trauma. This is why I have taken tomograms and now CBCT on almost every patient we see. Most of these young people are asymptomatic (Figure 4). The joints shown in Figure 4 are from a 15-year-old who came in for aligner treatment. What to do? Take CBCT on all patients. You never know.

Observation 5 I have placed two wires initially since 1971. Since 1987, my initial wires have been .014 NiTi fully engaged with steel ligatures and then active self-ligating brackets. We see the patient at 12 weeks for a check and then reschedule him/her for another 12 weeks. If turbos are routinely used, alignment and rotations are corrected (usually

8-10 weeks), archform is complete, Curve of Spee is corrected, and molars are derotated, correcting a large number of Class IIs, and any nonparallel roots are mostly parallel. The force of twin wires is minimal, if a tooth is significantly malaligned. Then only one of the wires is engaged initially. The other wire is engaged at the 12-week appointment. Teeth move rapidly, and discomfort is minimal (4 out of 10) when patients were asked pain levels. This was asked of each full-bonded patient over a more than 8-year period (Figure 5). Figure 6 shows the same patient after a little over 5 months, when a rectangular wire was placed in each arch. Appointments have been reduced significantly, and root resorption is virtually not seen. The friction or binding that we have been told to be worried about plays no part in rate of tooth movement. What to do? Routinely use two .014 NiTi superelastic wires initially.

Observation 6 Where it is applicable, use anterior turbos made of clear Triad® material. Why are they so important? There are a number of reasons: 1. The posterior teeth do not meet, so the Curve of Spee is corrected permanently in most cases. I keep turbos on for at least 10 months. This allows the lower posterior teeth to erupt quickly, but more importantly, bone fills in at the apices of these teeth. If the posterior teeth come together 2,000 times a day, there can be no bony fill, thus causing the Curve of Spee to eventually return. 2. Since the teeth do not meet in the posterior, premolar and molar brackets rarely fail. 3. Since only lower incisors contact the turbos, teeth move more quickly. 4. There is no wear of teeth as they transition from Class II to Class I. 5. Forces of occlusion are significantly diminished; therefore, muscles stay relaxed. 6. The condyles stay “hinged” in an ideal position.

Observation 7 Over the years, I have attempted many options to bring in impacted canines. Most have been successful, but they took too much time — lengthened treatment time in order to make space for the canine first and then to expose the tooth, perhaps have it passively erupt, then move the tooth in multiple directions in order to get it into the arch. Since 1991, I have used one and only one method to bring in all impacted canines. These conditions must be present: • The use of a molar tube with 20 degrees distal rotation and 20 degrees of torque — Roncone PDS anchorage molar Figure 4: Significant DJD right condyle

Observation 4


CASE STUDY • A single-strand .018 HANT wire • A gold chain attached to the impacted tooth In most cases, an open coil spring, etc., does not need to be used to open space. Bringing in canines in the manner I will demonstrate in Case 1 and Case 2 has worked thus far for every patient whether labially or palatially impacted but one. The one patient commuted from the Midwest and had three other orthodontists involved who kept changing the protocol. That patient lost two teeth and needed implants.

What to do? Case 1

Figure 7: Placement of brackets with 20/20 molar. No elastics, open coil springs, TADs, or co-ligation of teeth were ever used. Space was made by using a large NiTi wire (.018), causing rotation of maxillary right first molar and friction/binding. After 10 weeks, the impacted canine (labial) was ligated, and the wire placed through a link on the gold chain

BioDigital Orthodontics Management of skeletal deformities with orthognathic surgery (OraScan) (3): part 18 Drs. Rohit C.L. Sachdeva, Takao Kubota, and Jun Uechi discuss the Type three approach for planning and managing surgical patients with suresmile® when only 3D intraoral scans are available Introduction suresmile technology enables the orthodontist to plan surgical treatment in 3D and design staged pre-surgical and post-surgical prescriptive archwires based upon patient needs.1-17 Also, the interactive nature of the software allows both synchronous and asynchronous planning of care with members of an interprofessional team in situ or virtually. In previous articles,16,17 three approaches to planning care for orthognathic surgical patients were described (Sachdeva). In this paper, the Type three approach for planning and managing surgical patients with suresmile when only 3D intraoral scans are available is discussed. ®

Patient K.T. Patient K.T. presented to the clinic at the age of 19 with the chief complaint of “my front teeth don’t meet, and my jaw seems to be shifted.” Both the clinical and cephalometric findings suggested that the patient presented with Class III asymmetry accompanied with a dental open bite (Figure 1). No mandibular

shift was detected, all teeth were present, and the 8’s were unerupted. Patient K.T.’s oral hygiene was satisfactory. The treatment plan was initially designed in 2D using WinCeph® Ver 9.0 software from Rise Inc. (www.risecorp.co.jp) (Figure 2). The displacement coordinates of the mandibular movements obtained from the 2D plan were used as a guide to plan the A-P movements of the mandibular arch on the VDM. Both transverse and A-P mandibular skeletal movements were simulated in 3D. Dental movements were planned next. Note, in conjunction with surgery, dental expansion of the maxillary posterior teeth and eruption of the maxillary anteriors are needed to coordinate the arches and plan for appropriate overbite (Figures 3A-3F). The patient’s upper arch was bonded with Tomy OPA-K® (www.tomyinc.co.jp) brackets with 0.018” slot width. Initial alignment of the upper arch was started with .016" SE CuNiTi AF 35°C Ormco™ (www. ormco.com) (Figure 4). Four weeks later, an upper quad helix was inserted to expand the upper arch (Figure 5). At the next appointment (week 8), the lower arch was bonded

with GAC .018" brackets, and alignment in the lower arch was started with a .016" SE CuNiTi AF 35°C (Figure 6). Twelve weeks later, the previous wires were replaced with .016 x .022 CuNiTi AF 35°C (Figure 7). A Therapeutic scan for patient K.T. was taken 4 weeks later (Figure 8). Although the planned maxillary archwidth was achieved by expansion, the anterior open bite increased (Figure 9). The superimposition of the Virtual Diagnostic Model (VDM) versus the Virtual Therapeutic Model (VTM) shows this (Figure 9D). The open bite was created as a result of the reactive intrusive forces felt by the upper anterior segment in response to the extrusion of the upper canines. The leveling of the lower arch also contributed to the increased open bite. The definitive surgical treatment plan was designed using the VTM (Figure 10A). Note both the upper and lower anteriors were extruded dentally to reestablish the esthetic occlusal plane (Figures 10B-10D). For patient K.T., a hybrid active-passive surgical archwire (Sachdeva classificationType 4) described in an earlier article8 was designed (Figure 11). This means that the wire was designed passively for the posterior segments and actively to extrude the anterior segments. The reason for this was to take advantage of the Rapid Acceleratory Phenomenon (RAP)18 that would be triggered post-surgically to extrude the anteriors rapidly. Upper and lower .017" x .025" CuNiTi AF 35°C suresmile precision archwires were inserted 4 weeks later (Figure 12). The patient was operated on the next day immediately post-suresmile archwire insertion. This mitigated any tooth displacement that could impact the fit of the surgical splint.

Conclusions The total treatment time for patient K.T. was 7 months. Serial archwire changes could have been avoided by beginning with .016" x .022" AF 35°C CuNiTi archwires in both the upper and lower arches. Additionally, the lower arch could have been bonded at the first appointment with the upper arch and the upper quad helix appliance placed. These actions would probably have saved at least 8 weeks in treatment time. The iatrogenic side effect of intrusion of the upper anteriors could have been minimized by either asking the patient to wear box elastics anteriorly during first alignment or with the use of overlay mechanics. A passive upper archwire could have been designed with suresmile bypassing the canines to hold the posterior and anterior segment rigidly. Concurrently, a .016" SE NiTi archwire could have been overlaid on this wire and the canines engaged to extrude them. Patient K.T. demonstrates the versatility in the use of suresmile technology, which allows the clinician to design a patient’s care plan in 3D and offers her the ability to design plan specific archwires. In the case of patient K.T., it was an active-passive hybrid precision archwire. OP

The host in the machine Dr. Jonathan Nicozisis waxes philosophical on Propel Orthodontics’ Excellerator technology

T

he machinery that is involved in orthodontic tooth movement is a complex milieu of cascading events and tissue reactions of the host periodontium. As the oldest specialized discipline in dentistry, we have researched and understood the periodontal response when forces are imparted on teeth better than anyone else. We fully understand the direct connection of the physical push and pull that elicits bone remodeling to satisfy the body’s mindful desire to return to homeostasis. The “ghost in the machine” is a concept describing philosopher René Descartes’ mind-body dualism to explain mental activity carrying on in parallel to physical action, but where their means of interaction are unknown. To translate, it is the notion that the mind is distinct from the body, and that mental

states are separable from physical states. Hence “the ghost in the machine” describes the fundamental distinction between mind and matter with the presumption that they act independently in parallel without a direct cause-and-effect relationship. As orthodontists, we certainly know this is not the case in what we do. We appreciate that there is a direct cause and effect of our mental planning of mechanics to accomplish physical tooth movements given our initial diagnosis and planned treatment. Our everyday routine actions, however, have created a mental complacency that has lulled us into repetitive activities, robbing us and our patients of novel processes to provide better outcomes in shortened treatment times. In a sense, unknowingly, a disconnect has developed between our

thoughts in planning and how our physical mechanics are received by the host tissues of the periodontium. This is our orthodontic ghost in the machine. Simply put, we have forgotten the details involved in the physiology of tooth movement and thus do not even think of the possibility of enhancing the process to our advantage; for doctors in private practice, the host in the machine that is the periodontium reacting to orthodontic tooth movement has been overlooked for too long, thus resulting in this disconnect. Prior to today’s technology, the connection between our mental thought processes to augment the physical reaction of the host tissues was to apply either a heavy or a light force. Heavy forces were reserved for

Jonathan Nicozisis, DMD, MS, has been in the specialty practice of orthodontics since 1999. He completed his dental education at the University of Pennsylvania before attending Temple University for his orthodontic residency. While at Temple University, Dr. Nicozisis received his specialty certificate in orthodontics and a master’s degree in oral biology. During his training, he also completed an externship at the Lancaster Cleft Palate Clinic in Lancaster, Pennsylvania, where he was involved with the care of patients with craniofacial syndromes. Dr. Nicozisis is a member of Invisalign® National Speaker’s Bureau and Clinical Research Network where he helps conduct research and development of new technologies and improvements to the Invisalign technique. Dr. Nicozisis is also the founding orthodontist and a scientific advisory board member of BAS Medical (now Corthera), a development stage company founded in 2003 with a mission to develop and market a novel technology to accelerate and improve the stability of orthodontic treatments. Dr. Nicozisis’ master’s research is the basis for BAS Medical innovative research. In February 2010, Corthera was acquired by Novartis. Dr. Nicozisis has been awarded membership to the Edward H.

skeletal movements (think cervical or highpull headgear, protraction face masks, and palatal expanders), whereas light forces were applied for tooth movement to minimize tissue ischemia and promote frontal resorption as opposed to undermining resorption. The basic science behind Propel Orthodontics’ proprietary Excellerator technology is the answer to the ghost in our own machine that is orthodontic tooth movement. To that end, Propel allows us to connect the mental understanding of the physiology of tooth movement and physical actions to elicit the desired movement. More so, Propel now affords us the capability of enhancing this connection between our understanding and actual undertaking of tooth movement to our advantage and benefit to the patient. Modestly put, an increase in local inflammation via transmucosal osteoperforations causes an increase in osteoclast recruitment and differentiation. This causes the bone to remodel faster, and therefore, teeth move Volume 6 Number 6

faster through the bone. Doctors are in full control and can target where this facilitated phenomenon occurs without relying on patients for compliance. The parallel knowledge of and physical stimulation of the host machinery involved in orthodontic tooth movement is now truly linked. Decades of academic research is crossing over into private practice and practical application in a non-disruptive way regardless of the modality of treatment chosen for our patients’ benefit. Patients benefit from shortened treatment times, which means less time in orthodontic appliances or aligners. Furthermore, it means fewer visits to the office and taking less time away from work or school to complete treatment. Finally, there is no recovery from the procedure, and patients can go about their day without any downtime or discomfort. Doctors benefit from better outcomes in less time. This means less chair time overall to finish each case with an increase in profitability

Euclid had his postulates in Geometry. Nicozisis has his postulates of Propel: 1. Incorporation of Propel in a treatment plan and the corresponding decrease in number of visits to complete the case is congruent with an increase in profitability per visit. 2. If there is a space that exists between two teeth, then there exists one Propel procedure that will close the space faster than conversely without Propel. 3. A single office visit with a nominal increase in chair time of no more than 15 minutes for all four quadrants will substitute for a savings of two to three visits to produce the same movements. 4. The Fourth Order of Orthodontics is elicited with Propel allowing doctors to augment the host tissue response to their advantage preceding force application. 5. Doctor-controlled and targeting capabilities are characteristics inimitable to Excelleration with Propel. 6. If X is a variable, the one’s investment of $”X” thousand in Propel will translate in effecting 4.0-5.5 times “X” patients versus effecting 1 times “X” patients with other devices currently in the market place. per visit. Distinct marketing advantages of Propel accelerating orthodontic technology help attract new patients to the office as well as convert those who may have been reticent based on the length of time they were originally quoted. If the average case takes one to three devices, the modest increase in overhead, approximately $100-$300, is well worth the savings elsewhere. The concept of mind-body dualism need not be reserved for philosophers waxing poetic on explaining the possible parallel nature of human being’s mental and physical activity. It can now be applied to bridge the fine gap between the basic science research behind Propel Orthodontics’ Excellerator technology and actual clinical application to the mutual benefit of both patients and doctors. The complacency of our mundane day-to-day office routines can now be filed in the history chapters of our orthodontic literature!

Management of TMD during orthodontic treatment: disc displacements Dr. Harold F. Menchel discusses how to proceed when a patient develops TMD symptoms during treatment

E

very orthodontist dreads the emergency call from the parents of an adolescent in active treatment. “My daughter woke up this morning with jaw pain, and she can’t open her mouth!” Most TMD orthodontic emergencies involve young female adolescents with disc displacements. It has been my experience as a graduate instructor in dental programs that many orthodontists are not familiar with diagnosis or management of these patients. This article will give you the essentials to manage this common occurrence.

Introduction TMD disorders occur primarily in the female population (85%).1,2,3 Disc displacements occur most often in young postpubertal females.4,5,6 This makes them common in the orthodontic population. • Hormonal influence (estrogen metabolism) has been suggested as a possible etiologic factor, but the exact mechanism is unknown.7 • Hypermobile patients have a higher incidence of disc displacement.8 • There is weak evidence that Angle Class II patients are more prone to this pathology, especially Division II.9,10 • The majority of these patients exhibit parafunction (particularly clenching). • In most patients, this pathology is preceded by biochemical changes in the synovium and is not strictly a mechanical joint problem.12 • Disc displacements without reduction have a higher incidence of arthritic joints as the patient ages, but this does not always occur.13,14

Educational aims and objectives

This article aims to discuss how proceed when a patient develops TMD symptoms during treatment.

Expected outcomes

Orthodontic Practice US subscribers can answer the CE questions on page 43 to earn 2 hours of CE from reading this article. Correctly answering the questions will demonstrate the reader can: • Identify some reasons for TMD disorders to occur. • Identify some common reasons for TMJ disc displacements. • Realize some possible prevention methods for TMD problems. • Recognize some differentiations between disc displacements and other TMD diagnoses. • Discuss management of patients who develop locking during treatment.

Disc displacements TMJ disc displacements occur when the disc is mobilized when the infratemporal fossa ligaments are stretched and the disc assumes a position anterior, lateral, medial, or posterior to its normal position. These can occur from macrotrauma or microtrauma over time. The most typical displacement is anterior-medial.

Subjective history The most common presentation of these patients is a history of increasing clicking and popping progressing to occasional locking, and then typically, the patient wakes with a limited opening or suddenly locks while eating chewy food. Many of these patients are habitual gum chewers and nail biters. There are several reasons for the jaws locking, including acute contraction of the masseter and temporalis muscles, the squeezing out of the joint the synovial fluid that provides lubrication for the joint, and a displaced disc.

Harold Menchel, DMD, is a dentist in Coral Springs, Florida, who limits his practice to TMD, orofacial pain, and sleep-disordered breathing. Dr. Menchel teaches undergraduate and graduate education in TMD and orofacial pain at Nova Southeastern School of Dental Medicine in Ft. Lauderdale Florida. He is the director of orofacial pain at Larkin Teaching Hospital in Miami and lectures both nationally and internationally. He is a fellow of the American Academy of Orofacial Pain, a Diplomate of the American Board of Orofacial Pain, and a member of the American Academy of Dental Sleep Medicine.

Figure 1: The posterior band of the disc 40 Orthodontic practice

Figure 2: Routine palpation of masseter muscles

Prevention The best prevention for TMD problems is a thorough TMD examination prior to starting orthodontic treatment in every patient. The following procedures should always be included for every new patient. • Palpation of joints and muscles for pain • Measure initial range of motion (normal opening 45 mm-55 mm) • Documentation of joint noises • Documentation of deviation on opening and protrusion • Measurement of excursive movements to see if they are normal and symmetrical • Patients with disc displacements will often deviate initially to the side of the Volume 6 Number 6


Diagnosis of disc displacement with reduction Disc displacements have to be differentiated from other TMD diagnoses: myospasm, arthritis, or post-injection trismus.15 • History of painful clicking and popping and occasional locking with increasing symptoms • Limited opening (usually 25 mm35 mm) with a “hard” end feel. (The patient has a consistent opening measurement with no “give”) • Deviation to the side of the disc displacement on opening and protrusion • Limitation of movement to the contralateral side • Disappearance of joint sounds with locking • Tenderness over the TMJ lateral pole • Decrease of pain with placement of separator on the side of the disc displacement; increase in pain with placement on the contralateral side (Mahan’s sign)16

Management of orthodontic patients with disc displacements Reducing displacements • Painless clicking and popping with no dysfunction (locking) can be treated normally, but with caution if the patient develops symptoms! • Patients who have painful clicking and locking should have conservative TMD therapy until there is no pain or dysfunction and then proceed with orthodontics with coordination of treatment as necessary with an orofacial pain dentist. • Asymptomatic clicking and popping during treatment should be noted, but treatment may continue. • Judicious use of anterior repositioning appliances during therapy should be considered. Non-reducing displacements Most patients with disc displacements do not develop significant occlusal changes.17 It is conjectured that the posterior occlusion should be heavy on the side of the displacement with an anterior open bite, but this is not consistently seen in practice. The reason for this is unknown. Patients with limited opening and pain prior should have no ortfhodontic treatment until pain is managed and the ROM is normal! • These patients can be treated “off the disc” after ROM is normal. Pain

is managed with conservative TMD therapy. • Some patients may require either arthroscopic lysis and lavage or discopexy (disc repositioning) prior to orthodontic treatment. In my practice, this is less than 10% of the patients with disc displacements without reduction .1 • If surgery is performed, it is recommended that orthodontic treatment be delayed 3-6 months for healing and for occlusal changes to stabilize.

Management of patients who develop locking during treatment Management of these patients is always easier the later in treatment the disc displacement occurs. The use of anterior repositioning appliances in these patients is questionable. In cases of non-reducing joints or in the later stages of internal derangement of the TMJ, it is not possible to achieve a normal disc-condyle relationship using protrusive splints.18 The main reason is that non-reducing disc displacement cannot occur without the loss of disc contour, which has the responsibility of providing the anatomic basis for normal disc position. However, this change is gradual. The acute stretching of the ligaments and comcomitant joint laxity as well as normal traction of the lateral pterygoid muscle now being pathologic are responsible for difficulty establishing a normal condyle disc relationship.

Figure 5: Disc displacements with and without reduction. On the top you can see the condyle closed (on the right with disc anterior to the condyle). This reduces or repositions into normal position on top of the condyle when the patient opens and the condyle translates. This is a “clicking “ joint. On the bottom, the disc is far anteriorly displaced so that it does not reduce to its normal positioning and blocks the opening Orthodontic practice 41

disc displacement, and then when it reduces (clicks), they will come back to center with an “S”-shaped opening • Panorex radiographs


CONTINUING EDUCATION • Mechanical tooth movement should be stopped until symptoms are reduced and opening is normal. • There are three ways to treat disc displacements without reduction during orthodontic treatment without removing the appliances: 1. Use bonded anterior bite stops or bite turbos to prevent any further posterior positioning of the condyle in the infratemporal fossa of the mandible and to act as a temporary splint. 2. Have the orofacial pain dentist place the splint over the appliances on one arch. He will request that you remove the arch wires and take alginates for him. When the patient is comfortable, turbos can be placed and the treatment finished.

3. “Flip splints.” This is the most time-consuming method but sometimes has to be done in severe cases. Move the teeth opposing the splint until you are finished, and then “flip” the splint to the other arch now finishing your orthodontic movement on the arch with previous splint.

Conclusions Disc displacements sometimes appear in the orthodontic population. The best way to manage them is with a TMD examination prior to treatment and then TMD treatment before any orthodontic movement. If the disc displacements occur during treatment management, techniques are discussed in many cases without removing the orthodontic appliances. OP

Retention of cases with disc displacements or general bruxism Splints are usually required for retention especially where bruxism is evident. The simplest configuration is an upper flat plane splint against a lower bonded retainer or lower labial bow retainer. Essix retainers are contraindicated because the occlusion cannot be adjusted. Invisalign® retainers present the same limitation.

Clinical tips to increase consistency using a “Straight-Wire Appliance” Drs. Tom Pitts and Duncan Brown discuss an efficient, gentle approach to orthodontic treatment

“E

verything should be made as simple as possible, but not simpler.” — Einstein Orthodontic clinical procedures and esthetic preferences are evolving toward fuller lips, greater enamel display, and wider smiles with a reduced tendency toward fourpremolar extractions, with increased preference for non-extraction treatment.1 The clinical approaches that we rely on today are different from those earlier generations of orthodontists used frequently.1 Esthetic declines, once common with treatment,2 are no longer acceptable to the majority of patients, and “straight teeth,” once the predominant treatment goal, is now secondary to strategies directed toward esthetic improvement3 (Figures 1-2). Most orthodontists use a variation of the “Straight-Wire Appliance,” a concept that has dominated our profession since Dr. Larry Andrews’ breakthrough article4 led to its development in the 1970s. In the last 2 decades, appliance developments have revolved around relatively minor changes in

appliance prescription, direct bonding, the development of PSL (Passive Self-Ligating)/ ASL (Active Self-Ligating) ligating mechanisms, increased use of sliding mechanics, and incorporating reduced force levels.5 The recognition that certain torsion concepts of “straight-wire” theory are not congruent with some modern esthetic goals or with contemporary mechanics does not diminish the value of Dr. Andrews’ landmark concepts. Orthodontists must appreciate the

biomechanical flexibility that is required to use the appliance for improving the quality of treatment results. There was a gain in popularity in ASL/ PSL systems during the 1990s when small wires in a larger “closed” slot provided effective movement due to reduced Resistance to Sliding (RTS). For many orthodontists, when larger rectangular wires were used during major tooth movement, results were disappointing5 with “sloppy slots” that lacked

Clinical Tips • Don’t get stuck in a biomechanics rut that doesn’t deliver exceptional esthetics: (Impressive Smile and Facial Esthetics has been my field of interest for the last many years.) Most orthodontists appreciate Andrews’ “Six Keys to Normal Occlusion” — (Key 1) the characteristics of molar relationship, (Key 2) crown angulation or tip, (Key 3) crown inclination, (Key 4) no rotations, (Key 5) absence of spaces, and (Key 6) occlusal plane — as being important features of a sound functional occlusion. The work of Dr. David Sarver clearly describes characteristics of great esthetics that supplement the criteria applied to normal occlusions8. The biomechanics and case management used by esthetically motivated orthodontists to achieve great occlusions are likely considerably different from those who are mainly occlusally motivated. Put simply, “Great Occlusions don’t always equal great esthetics,” so clinically, find ways to achieve both. • Try “Active Early” case management protocols: In “Active Early” protocols,7 the appliance is activated as early as

possible, using the Smile Arc Protection (SAP9) bracket position to adjust vertical position of the incisors, inverting groups of brackets when necessary to activate torsion in the appliance, selecting archwire progressions that control axial inclination early in treatment, wider arch forms that develop the posterior segments of the arches sooner, esthetic arch shape, ELSE (Early Light Short Elastics) to control forces and moments, and appropriate disarticulation to encourage early “wanted” tooth movements.6 This controls early vertical erupion and intrusion of teeth. Using these strategies improves patient management efficiency for us (Figure 3). • Diagnose in Natural Head Position (NHP): Diagnosis for esthetics is based on how the patient presents in day-today activity.8 As NHP is reasonably stable in both the short- and long-term,10 the patient should be assessed comfortably standing, engaged in natural conversation, and generating unposed smiles. The orthodontist then makes patient specific determinations of bracket height progressions to generate optimal enamel display8 and assesses the requirement for creation of torsion within the appliance to optimize axial inclination of the maxillary anterior teeth (Figure 4). Far too many finished orthodontic patients end up with proclined maxillary incisors, so we are purposeful in the assessment. • Optimize tooth shape, and improve gingival contour prior to bonding: The value of optimizing micro-esthetics in finishing is well appreciated.11 The less common strategy of creating a normalized contour of the teeth through positive and negative coronoplasty prior to bonding creates a number of opportunities. Ability to place brackets in vertical positions designed to enhance the smile

arc, simplified correction of rotational control, and more predictable performance in third order movements are all benefits of normalizing tooth shape and contour prior to bonding. As SAP upper bracket positions to optimize esthetics are frequently more gingival than conventional positions, soft tissue recontouring can be a tremendous advantage when needed (Figure 5). • Increase torsion “built into” the appliance by “flipping” where needed: Torque expression is a complex process dependent upon12 magnitude of torsion, wire stiffness or resilience, bracket design, engagement angle, mode of ligation, wire dimension and corner radius of the wire, angulation of the bracket, deformation of the bracket or wire under torsion, manufacturing tolerances in the bracket and the wire, initial tooth inclination, bracket position, and the measurement technique used to evaluate torsion. Fortunately, to the clinician, it matters solely when/if torsion is developed within the slot during commonly used archwire progressions.

control of axial inclination and rotations. Passive ligation demands very accurate slots with special dimensions, particularly in the anterior region for obvious reasons. We favor the use of a PSL mechanism for many reasons: quick wire changes, consistent bracket engagement, lower forces and wire sliding with control, and improved hygiene, among others. We combine proven PSL case management strategies6 and “Active Early” approaches7 to control torsion and arch development, with the improved slot geometry and tighter tolerances of the H4™ appliance (Ortho Classic), along with more esthetic arch forms.

With the worldwide tendency to treat more patients without extractions, the control of proclination of the maxillary anterior teeth has become a greater challenge. The correction of pre-existing crowding and proclination, proclination associated with relief of crowding during traditional round wire mechanics, or incisor proclination-associated Class III elastics is particularly problematic. The challenge for many non-extraction patients has been in getting enough lingual crown torsion without having to resort to complex wire bending to attain esthetic results. These are patients that benefit from “flipping (upper anteriors) and flocking (upper cupid)” the maxillary anterior/canine brackets.13 The “tooth by tooth” method of varying torsion “built into” the appliance is not as efficient for us and frequently requires either repositioning of brackets, or complex wire bending to finish precisely.14 In contrast, “flipping and flocking” and varying torsion in groups is far more predictable, requires fewer bracket repositions, and allows wire adjustments with uniformly “spun” wires (Figures 6-7). • Bond brackets to optimize esthetics not at the center of anatomic crown (FA): As today’s treatment targets for incisor position in three planes of space are based on esthetics,8,15 the reliance on “treatment built” into an appliance for the anterior teeth relative to the occlusal plane is not a practical way to ensure esthetically superior results. In the “Active 46 Orthodontic practice

Figure 8: SAP versus traditional bracket placement: For smile arc protection or enhancement, the wire plane should be parallel to the upper lip in a posed smile, and the incisal edges parallel to the lower lip. (Image courtesy of Dr. Tom Pitts, 2013)

Early” approach, individualized bracket positions based on esthetics7 (SAP) is combined with other initial planning considerations to gain control of maxillary incisor vertical position. For patients with “flat” occlusal planes or those that require increased enamel display, the divergence of the upper wire plane from molar to incisor created by bracket position must increase to develop the smile arc by extruding the upper incisors relative to the upper premolars. In patients with normal occlusal planes, a more modest progression in the upper wire plane is still advisable to protect the smile arc as we broaden the maxillary arch with treatment. A modest progression in still advised in deep bite cases to avoid excessive reduction in the smile arc as the overbite reduces. Compensating changes in the mandibular wire plane levels the mandibular arch and establishes an optimum overbite. It is not necessary to have a deeper bite to have a great smile arc.

Andrews’ “Six Keys” article, acknowledged as the catalyst for development of the first fully pre-adjusted appliance, advocates using the center of the clinical crown (FA), the long axis of the center of the clinical crown, and the thickness of the clinical crown from the long axis to FA,5 as guides for bracket positioning. This limits the usefulness of the appliance for patients whose teeth or faces deviate from “normal standards.” We do not subscribe to the core “straight-wire” principle that the wire plane must parallel the occlusal plane to attain excellent occlusions, and failure to adjust bracket height to adjust vertical positions of the maxillary incisors can result in esthetic deterioration. SAP bracket placement strategy allows adjustment of the vertical position of the maxillary incisors, which improves their display and the smile arc without increasing the overbite (Figure 8). • Appreciate the reality of undersize wires and oversized slots: Contemporary fixed orthodontic treatment is usually completed in wire sizes that are less than full dimension15 for the designed bracket Volume 6 Number 6


unpredictable. However, with the H4 bracket, the manufacturing tolerances are predictably accurate, with reduced slot depth leading to less wire adjustments. By varying bracket height with SAP bracket positioning and “flipping and flocking” maxillary anterior brackets when needed, lingual crown torsion is assured. By proper management of mandibular incisors, those teeth can be kept upright when required (Figure 10). • Use broader arch forms for better esthetics: Dr. Pitts has found that broader arch width, (not in the canine region) especially in the molars is more attractive, and smaller buccal corridors are preferred in both men and women. The alignment and broadening of maxillary and mandibular dental arches to reduce buccal corridors and producing “10” or “12” tooth smiles results in more space for the anteriors to have more lingual crown torque/inclination. Of course, proper inclination of the premolars and molars must be maintained upon broadening. Research has

confirmed that final arch width is a function of arch form, not of the bracket18 used during treatment, so an improved arch form is required for improved esthetics. One of the biggest impacts on transverse arch dimension in the molars, and arch form in general has been the adoption of “Pitts’ Broad” arch forms in both nonadjustable and adjustable wire profiles (Ortho Classic). This arch form improves the “flow” of mini-esthetics, making the attainment of a “12 tooth” smile much easier. By using a moderate progression SAP bracket placement, the orthodontist can broaden the arches and still maintain a beautiful smile arc (Figures 11-15). In short, the shape of the arch is just as important as the width. • Finish micro-esthetics details with optimal esthetics in mind: It was primarily the efforts of Dr. David Sarver who classified the concepts of macro-, mini-, and micro-esthetics19. While optimizing the “white and pink” tissues has been common practice in esthetic dentistry, it is less common in orthodontics20. By

slot dimensions. This seems gentler on the patient, and the consequences of this incompletely filled bracket lumen is torsional play that decreases engagement of the contact between the archwire and the bracket.16 While decreasing friction — a potential benefit during early leveling, aligning, and sliding mechanics — torsional play reduces control of axial inclination necessary for ideal esthetics. In clinical practice, incremental increases in archwire size is NOT the most effective means of controlling axial inclination when the slot isn’t filled7 (Figure 9). • Understand the appliance system you are using: Manufacturing tolerances also vary greatly so that the ability of the appliance to generate torsion with a specific wire progression and deliver stated appliance Rx17 is really what matters. Fortunately, to the clinician, it matters solely when/if torsion develops within the slot during commonly used archwire progressions. Unfortunately, many manufacturer’s tolerances often cause variable slot sizes, which makes torsion

mastering the techniques and disciplines applied in cosmetic dentistry, patients have the potential to finish with wonderful microesthetics that provide the final touch to patients who have well managed macroand mini-esthetic results (Figure 16). We take particular care in avoiding “black triangles” at the gingival papilla through management of contacts and connectors during the finishing process. It is an exciting time to be in orthodontics. Contemporary esthetic-based diagnosis, a modern understanding of how to optimize straight-wire appliances, use of advanced straight-wire appliances that control axial inclination and rotations, using esthetic broader arch forms, adopting the “Active Early” approach to case management, and finishing “white and pink” tissues for esthetics provide expanded opportunities for improving esthetics. In the “Active Early” approach, lighter forces, applied earlier, for longer duration are accomplishing many things more efficiently for the orthodontist and more gentleness for the patient than has ever been possible before.

PRACTICE MANAGEMENT

7 ways online patient communication tools can improve your practice efficiency Scott Eklund discusses the importance of having the right tools and systems for patient communication

M

anaging a successful practice isn’t just about delivering quality results. To stay profitable, orthodontists and practice managers must reduce no shows, keep schedules full, collect treatment fees, and attract new patients. In order to achieve these goals, your practice has likely developed a comprehensive, and perhaps complicated, set of systems to manage your daily activities. Many times these existing systems are carried out manually instead of being automated, leading to inconsistent results, inefficient use of your staff’s time, and unhappy patients. By implementing a robust patient communication system, you can automate many of your processes, save time, and improve the patient experience. The following seven tips will help you take full advantage of your patient communication system and improve your practice efficiency.

1. Appointment reminders and confirmations How much time and effort is spent in your practice making routine appointment confirmation calls, manually sending emails, or mailing postcards? Not only are these methods time consuming, they are also inefficient and inconsistent. By automating the appointment confirmation process through online communications tools, you can significantly cut down on the administrative work required to complete this routine task and drastically reduce no-shows. The numbers on this are pretty clearcut; over 85% of orthodontists say automated reminders reduced no-shows and increased production.1 These automated reminders reduce stress, as your team knows confirmations will be executed in a timely, complete, and consistent manner. In fact, 87.6% of surveyed dental professionals agreed that automated patient reminders give them the peace of Scott Eklund is the Marketing Manager at Sesame Communications, the premier provider of online services for the dental industry. Sesame helps dental and orthodontic practices harness the power of the Internet to accelerate new patient acquisition and transform the patient experience

mind to know that all patients are consistently contacted prior to their appointment.1

2. Collection calls Calling patients about past-due payments is both time consuming and awkward. As a practice that strives every day to build a strong, positive relationship with each patient, a call about a past-due payment can put stress on this relationship and may not always be effective in soliciting payment quickly. An email about a past due balance discretely nudges the patient and is much less confrontational or embarrassing than a personal phone call. Most importantly, this is less expensive and more effective in collecting payment. Research shows that within 24 hours of sending an automated past due balance email reminder, 32% of patients make an online payment. Within 48 hours, 50% will make an online payment.2

3. Payment processing Patients have come to expect online bill-pay with their utilities, credit card, and phone payments, so why is a payment for their orthodontist any different? The convenience of being able to pay online not only means a quicker turnaround for payments, but the ability to collect payment outside of office hours.

Sesame Members receive over 46% of their payments outside of normal business hours3 — meaning the money is in their account and waiting for them by the following morning.

4. Health history forms When new patients decide to start treatment, they are required to read and fill out an extensive amount of paperwork. This process takes a lot of time and effort by the patient, which slows down your patientintake process and ultimately makes your practice less efficient. By providing online health history forms, you allow your patients to complete the forms at their convenience and help make their initial visit more comfortable. It’s also more efficient — an online health history form keeps the data digital, where it can then be used by your practice management system and patient communication systems. It’s a high-tech timesaver that is fast becoming an expectation from patients.

5. Patient feedback Orthodontic practices can be a hectic environment, and many practices often fail to ask their most valued patients for feedback on how to better serve them. Feedback from patients is a crucial part of understanding where your practice excels, and where there is room for improvement. Timely feedback Volume 6 Number 6


6. Newsletters and greetings Patients want to know what’s new in your practice, and it’s your responsibility to keep them up-to-date. The average orthodontist has hundreds, even thousands of active patients. This magnitude of patients makes it difficult to have a personal connection with each one of them on a regular basis. By reaching them electronically through email newsletters, you can keep in touch with patients and facilitate their engagement in your practice on an ongoing basis.

In addition to formulating informative educational newsletters, a patient communication tool allows you to use email to automatically manage your holiday and birthday greetings. If you’re mailing postcards for these occasions, you can save both time and money by using an automated system. No need to worry about remembering a patient’s birthday; these reminders will go out automatically.

7. Daily schedule One of the most widely used tools of a successful practice is the daily schedule. This simple tool is the single most critical element determining production and profitability. In a fast-paced environment, it is imperative to have a functional schedule that provides you and your team with the necessary patient information so you can best serve them. A digital solution can help solve this by bringing your daily schedule and your practice management software together. Sophisticated patient management tools let you view your daily schedule at a glance from any computer, access all your patient data, control reminder settings, and more. Ensure the system you choose integrates with your

dental practice management software, so you’re always working off of the latest information for new and existing patients.

Take your practice to the next level Managing a successful practice takes a lot of work, but with the right tools and systems in place, you can improve staff efficiency, patient experience, and practice profitability. There are many patient communications systems in the market that have a lot of different features and price points. Make sure that the system you choose to work with has the preceding features at a minimum, and you will be on your way to practice success. OP

Controlled molar distalization James Bonham discusses a durable, comfortable, and predictable appliance

O

rthodontists today have multiple appliance options to achieve molar distalization. Some distalization appliances have a broader market exposure than others, usually created through podium speakers and company marketing campaigns. Recently, an appliance called the Rapid Molar Distalizer (RMD) has grown only by word of mouth to become the doctor- preferred distalization appliance at Specialty Appliances laboratory. After thousands of successfully treated cases, we wanted to share what makes this distalization appliance so exceptional. The Rapid Molar Distalizer (RMD) offers predictable molar distalization without molar tipping or anterior advancement. Using small expansion screws on the buccal of the arch, the RMD does not interfere with the patient’s speech or swallow pattern. Each screw is comfortably placed parallel to the buccal line angle or central groove, and capable of 12 mm of distalization. When seeking either unilateral or bilateral molar distalization, orthodontists have complete control through their prescribed screw activations. Each screw is generally activated twice per week (right Monday, left Wednesday, right Friday, and left Saturday) until desired distalization is achieved. With

only a ¼ millimeter activation per turn, there is no continuous pressure on the patient’s anterior tissue. This eliminates the Nance indent on anterior tissue and prevents tipping of anterior teeth that is seen in most distalization appliances. Appliance anchorage can be tailored to the patient. In the absence of fully erupted permanent second molars, the appliance is anchored to bands on the first bicuspids and first molars. The second bicuspid will generally follow the first molar down the alveolar process. If the patient has fully erupted second permanent molars, it is anchored to the second molar bands and the second bicuspids. In this case, the first molar will generally follow the second molar down the alveolar process. Lingual buttons are often added so power chain can close the diastema from the drifting teeth. Transverse corrections are often desired before distalization. The RMD can incorporate a palatal expansion screw in the second bicuspid area, soldered to the lingual support wire. The appliance has extension to the first or second molars as needed but is not soldered to the molar bands so distalization can occur. Digital scanning and computer-aided design technology delivers many positive workflow enhancements. The Rapid Molar Distalizer is the only distalizing appliance that allows for same day fabrication of both RMD and the holding Nance appliance. Because RMD distalization is measureable by the number of screw activation turns, simply inform the laboratory how much distalization is desired. Specialty Appliances will digitally replicate the prescribed distal movements and print a second model for Nance fabrication. With this new process, doctors eliminate a valuable appointment and deliver the Nance immediately after removing the RMD. Due to its solid reputation of durability, patient comfort and predictable results, the RMD has become the orthodontist’s distalizing appliance of choice at Specialty Appliances.

Martin Kaplan, DMD, and Peter Vitruk, PhD, explore soft tissue CO2 laser uses in orthodontics Introduction Soft tissue surgical lasers have many advantages over traditional scalpel surgery, cryosurgery, and electrosurgery. However, not all lasers are equally efficient at both cutting the soft tissue, coagulating, and hemostasis because light absorption in the soft tissue varies with wavelength.1-3 As illustrated in Figure 1, some dental laser wavelengths (around 1,000 nm, such as diodes and Nd:YAG) are efficient coagulators, but inefficient scalpels since they are poorly absorbed by the soft tissue. Other dental laser wavelengths (around 3,000 nm, such as Erbium lasers) are well absorbed by the water-rich soft tissue and are great at cutting, but are not as efficient at coagulating and hemostasis.

Why CO2 laser?

The 10,600 nm CO2 laser wavelength it is not as good as Erbium laser at cutting (but is a much better coagulator2) and not as good as diode/Nd:YAG laser wavelengths at coagulating (but is a much better scalpel2,3). As indicated in Figure 1, the 10,600 nm CO2 laser wavelength is a compromise for simultaneous cutting and coagulation/hemostasis; most importantly, the 10,600 nm CO2 laser’s coagulation depth closely matches blood capillary diameters2. The radiant energy of the CO2 laser is used directly to photothermally vaporize (cut, incise, ablate) and, at the same time, to photo-thermally coagulate the soft tissues. The CO2 laser is a “whatyou-see-is-what-you-get” surgical soft tissue

delivery systems. The flexible, hollow fibers, introduced in the 1990s, significantly simplified CO2 laser surgery. Modern flexible fiber CO2 lasers use a scalpel-like ergonomic autoclavable handpiece (Figures 2 and 3) for 1) cutting, 2) ablation, and 3) photothermal coagulation and hemostasis. Tipless CO2 handpieces are designed to operate without disposables. The right-angle, pensized tipless handpiece permits easy and convenient access to the soft tissue within the oral cavity in patients of all ages, including infants.5 Photo-thermal ablation and coagulation The photo-thermal ablation of soft tissue is a process of vaporizing intra- and extracellular water near the surface, where the laser beam intensity is at its maximum. For a fixed laser beam diameter (or spot size), the volume of the tissue exposed to laser beam is proportional to the optical penetration depth (inverse of absorption coefficient Orthodontic practice 59

TECHNOLOGY

Soft tissue 10,600 nm CO2 laser orthodontic procedures


TECHNOLOGY from Figure 1). The 10,600 nm CO2 laser is energy efficient at ablating the soft tissue photo-thermally with low ablation threshold intensities due to very small volume of irradiated tissue (because of extremely short absorption depth around 15 µm).2 Immediately below the ablation zone, the coagulation zone is located where the denaturation of soft tissue proteins occurs in 60°C–100°C temperature range. This process leads to a significant reduction in bleeding and oozing of lymphatic liquids on the margins of ablated tissue. For the CO2 laser, its excellent coagulation efficiency is due to the close match between the sub-100 µm6 photo-thermal coagulation depth2 and the oral soft tissue blood capillary diameters of approximately 20-40 µm7. Laser pulsing and controlling thermal effects Laser pulsing is as important for laser surgery as the wavelength — short and powerful pulses are often superior to long and weak ones. The exact physics of pulsed laser surgery deals with the Thermal Relaxation Time,2,3 which depends both on tissue’s light absorption and thermal diffusivity, first described by Einstein.8 The rate at which the irradiated tissue diffuses the heat away is defined by Thermal Relaxation Time TR, which equals approximately 1.5 msec for 75% water-rich soft tissue irradiated by the 10,600 nm CO2 laser. Practical implications of the Thermal Relaxation Time concept are simple, yet crucial for the appropriate application of laser energy. The irradiated tissue heats most efficiently when the energy of a laser pulse is high, and the duration of a pulse is much shorter than TR. The tissue adjacent to the ablated zone cools down most efficiently when time duration between laser pulses significantly exceeds TR. Such laser pulsing is referred to as SuperPulse (see Figure 4). SuperPulse minimizes the depth of coagulation and is therefore a must-have feature of any state-of-the-art soft tissue surgical CO2 laser. The optimal combination of the CO2 laser wavelength and pulsing results in a char-free and bloodless surgery. This also allows for a scar-free, uncomplicated healing that is valued by surgeons across all specialties such as dentistry, OMFS, ENT, and plastic surgery. Laser beam spot size for cutting and coagulation Just like the sharpness of the steel blade defines the quality and ease of the incision, the size of the laser beam focal spot defines the quality of the laser cut. The smaller 60 Orthodontic practice

The many uses for a soft tissue CO2 laser in orthodontics, such as gingivectomies, frenectomies, exposure of impacted teeth, and others, feature minimal blood loss and reduced discomfort for the patients. (or sharper) the focal spot of the beam, the narrower and deeper the incision. For cutting, the LightScalpel laser handpiece is maintained 1 mm–3 mm away from the tissue and is moved at a hand speed of a few millimeters per second as illustrated in Figure 3. Just like a dull blade cannot produce a quality incision, an oversized laser beam spot cannot produce a precise and narrow cut. For a rapid switch from cutting to photo-coagulation alone, the laser beam can be de-focused either by selecting a larger spot size, or by simply moving the handpiece away from the tissue by approximately 10 mm (for LightScalpel tipless laser handpieces), and “painting” the “bleeder” for enhanced hemostasis. Laser power density and depth of ablation For a laser scalpel, the power density of the focused laser beam is equivalent to the mechanical pressure that is applied to a cold steel blade. In other words, greater

laser fluence3 (i.e., higher power density and slower hand speed) results in greater depth and rate of soft tissue removal. During each SuperPulse pulse, the ablation depth δ is given by the formula δ = A (E – Eth) / Eth for the steady state ablation conditions3 where A is the absorption depth from Figure 1 and Eth is the ablation threshold fluence,3 and E is the fluence during the SuperPulse pulse. At the 10.6 µm wavelength of the CO2 laser, the ablation threshold for a water-rich soft tissue with an assumed water content of 75% equals approximately Eth = 3 J/cm2. For repetitive pulses that are scanned across the soft tissue, the fluence is defined by the pulse frequency and the hand speed: i.e., the depth of incision depends on laser power settings, spot size, and the surgeon’s hand speed (Figure 5). Two important built-in safety features are 1) sub-millimeter superficial depth of ablation and 2) approximately 0.2 mm ablation depth variation as distance to tissue changes in Volume 6 Number 6


TECHNOLOGY Figures 6A-6C: A. Pre-op view. Gingival hyperplasia due to poor oral hygiene. B. Intra-op view with laser markings prior to incision. C. Two weeks’ post-op view shows good tissue healing

1 mm–5 mm range, which makes the CO2 laser a gentler and more forgiving tissue vaporization instrument in comparison with a scalpel, electrosurge, or diode surgery. Also significant is the switch from ablation to coagulation mode by defocusing the beam, with laser beam fluence dropping below the ablation threshold of 3 Joules/cm2.2

CO2 laser use in the presence of orthodontia hardware Gingival hypertrophy (caused by orthodontic positioning and poor oral hygiene) as well as overlying operculum are common problems during orthodontic therapy.9-11 Drug-induced hyperplasia presents another challenge for some orthodontic patients.13 Additionally, orthodontic devices attract bacteria and thus exacerbate the inflammation; periodontal disease often worsens in adolescents with fixed orthodontic hardware.9-13 Figure 6 demonstrates completely bloodless CO2 laser gingivectomy around the mandibular incisors in the orthodontic patient. CO2 laser gingivectomies, such as the ones presented in Figures 6-8, help improve the esthetics and oral health; they also allow for more ideal bracket placement and quicker treatment with fewer appointments. Gaining access to an impacted tooth or teeth is often necessary in order to place orthodontic braces. With conventional scalpel surgery, many problems occur when placing brackets, such as sutures breaking before brackets are bonded. Brackets will not bond properly if enamel is wet due to bleeding. Clean, bloodless enamel is necessary for enamel acid etching and bonding of the composite resin. Using the CO2 laser to expose an impacted tooth produces a dry surgical field thus creating conditions required for immediate bracket bonding. The CO2 laser-assisted cuspid exposure procedure is shown in Figure 9. This quick CO2 Volume 6 Number 6

laser treatment allows access for bracket placement, saving the patient months of waiting for the tooth to erupt on its own. The CO2 laser provides a clean, non-bleeding border. The CO2 laser straight and angled handpieces, illustrated in Figures 2 and 3, permit a convenient reach into areas that may be obstructed by braces. Once an impacted tooth is exposed by laser ablation, the bloodless surgical field is ready for the next step. The orthodontic traction hook can be bonded to the exposed enamel immediately after ablation during the same visit,10,11 saving time for both the patient and clinician. Many patients require banding of molars, but an overlying operculum gets in the way of placing appliances on these teeth. The CO2 laser is an excellent tool to remove this excess tissue. Hemostasis allows for banding to happen immediately following CO2 treatment. Local anesthetic may be required in some cases. Figure 15 presents the LightScalpel LS-1005 CO2 laser operculectomy (3 watts SuperPulse Repeat Mode F1-7) prior to band placement. Bands were seated shortly after operculectomy was performed, in the same visit. An important safety consideration is the heating rate of the orthodontia that could be accidentally exposed to a direct laser beam. Due to the differences in the light reflectance of stainless steel at different wavelengths,14 the wavelengths of approximately 800 nm–3,000 nm (diode, Nd:YAG and Erbium lasers) are absorbed 50%-250% stronger than CO2 laser wavelengths around 10,000 nm. Such high reflectivity by stainless steel makes the CO2 laser the safest wavelength around stainless steel orthodontia. When compared to lasers, electrosurgical units present a different safety challenge of conducting electrical currents by orthodontic hardware during accidental contacts with electrosurgical electrodes.

TECHNOLOGY Minimized bleeding for enhanced visibility and precision The enhanced hemostatic ability and precision of the CO2 laser is especially valuable in visible (esthetic) zones. The CO2 laser surgical removal of the tissue presented in Figures 6-15 illustrates excellent coagulation and hemostasis due to a close match between the oral soft tissue blood capillaries’ diameters of 20-40 µm7 and the coagulation depth during soft tissue ablation.2 Incisions with minimal bleeding, or entirely bloodless incisions, provide great visibility of the cut site, and thus higher precision for a minimized tissue trauma and better esthetic outcome.9-13,15-17 For example, Figure 10 shows the use of LightScalpel LS-1005 CO2 laser (2 watts SuperPulse Repeat Mode with F1-6 through F1-8 settings) for soft tissue crown lengthening of the maxillary incisors and for labial frenum revision. Both procedures were performed during the same visit while the patient was under anesthesia. No sutures were placed. Figure 11 presents the selfcorrection of a rotated tooth No. 9 after frenum revision. Laser frenectomies in Figures 12 and 13 resulted in spontaneous closure of midline diastemas. In comparison with traditional scalpel surgery, the precision of CO2 laser ablation allows for sub-millimeter control over tissue vaporization depth (Figure 5). The CO2 laser accuracy is especially important for highly vascularized areas. For example, the 14-year-old patient in Figure 14 had a CO2 laser lingual frenectomy performed during which a sublingual vein was exposed and coagulated (sealed) with a defocused laser beam. As a result, no sutures were needed, and the surgical wound was left to heal by secondary intention. Tissue healing With CO2 laser-assisted oral surgery, sutures are often not necessary, unlike with scalpel procedures. Laser wounds are often left to heal by secondary intention, as presented in Figures 6-14. Studies have shown that there is a diminished risk of scarring and wound contraction associated with CO2 laser surgery.18-22 Laserinduced wounds heal with greater fibroblast proliferation, with young fibroblasts actively producing collagen. Laser wounds also have been reported to contain smaller amounts of myofibroblasts (cells responsible for wound contraction), compared to scalpel wounds.22-24 Secondary intention healing and lack of scarring are especially important 64 Orthodontic practice

for treating lesions located in esthetic/visible zones. Reduced postoperative pain and discomfort It is important to avoid charring or causing excessive thermal damage to soft tissue. The experienced CO2 laser surgeon using the proper laser settings and hand speed will have small (sub 50 microns thick) zones of thermal necrosis.5 Patients report less postoperative pain and discomfort with laser surgery.25 The healing process associated with CO2 laser surgery is enhanced and less painful than with cryosurgery or electrosurgery.20-21

Summary The many uses for a soft tissue CO2 laser in orthodontics, such as gingivectomies, frenectomies, exposure of impacted teeth, and others, feature minimal blood loss and reduced discomfort for the patients. In comparison with other dental laser wavelengths (circa 1,000 nm for diode and

Nd:YAG lasers and circa 3,000 nm for Erbium lasers), the CO2 laser wavelength exhibits the least absorption rate by the stainless steel orthodontia hardware, and the optimum coagulation depth closely matching gingival blood vessel diameters. The CO2 laser ablation depth is controlled to a few tenths of a millimeter, which characterizes this wavelength as a safe and gentle soft tissue removal tool, while the sub-100 micrometer coagulation depth (better than diodes and electrosurgery) allows for enhanced, scar-free healing of highly vascular oral tissues (often by secondary intention). The accuracy and precision of CO2 laser surgery are increased by the visibility of the surgical field not being obscured by bleeding. OP
