PROMOTING EXCELLENCE IN IMPLANTOLOGY


FIXED-HYBRID EMERGENCY! Why Redo When You Can Rescue? When a failing implant needs to be replaced in a fixed-hybrid case, it often leads to a prosthesis emergency. Replacing the prosthesis was the only available option as it was impossible for the existing screw-retained components to realign back into the original position and maintain a passive fit. UNTIL NOW! The LOCATOR F-Tx® Fixed Attachment System is the ONLY immediate treatment solution available today that can rescue a patient’s existing fixed-hybrid prosthesis after replacing an implant. The novel, “snap-in” attachment is picked up chairside, ensures a passive fit, and works in harmony with the existing screw-retained fixtures saving both clinicians and patients substantial time, money and frustration.

’ve been placing and restoring implants in my practice for more than 22 years and have been teaching implant techniques to colleagues for 17 years. During that time, every aspect of implant treatment has evolved and dramatically improved. In my mind, the most significant development has been the use of 3D imaging for diagnosis and treatment planning. To name just a few benefits, CBCT scans enable us to precisely assess bone quality, determine the orientation of the implant to accommodate planned restorations, and virtually eliminate the risk of complications, such as nerve damage and sinus penetration, by taking the guesswork out of implant size selection. In Ara Nazarian, DDS, DICOI 2018, 3D imaging is unquestionably the standard of care for the implant dentistry. I can’t imagine practicing without it. Cone beam is just one component of implant treatment’s digital workflow. Combined with intraoral scanning, we can now create virtual models from which surgical guides can be made. Again, we’re removing the guesswork from the placement procedure. Bone grafting is another important aspect of implantology that I concentrate on in my courses. From innovative delivery modes to advanced chemistry and manufacturing, available systems for regenerating bone have made treatment a possibility for individuals who previously could not have supported an implant restoration. And of course, implants themselves are constantly changing as new design elements are discovered — a trend that’s been covered closely in the pages of Implant Practice US. Narrow diameters and short heights, innovative tapers and angles, and integration-promoting coatings and threading are just some of the advances that have increased the rates of clinical success. I work closely with researchers and manufacturers, and I can assure you that this spirit of inventiveness will continue. The goal: to simplify treatment, enhance predictability, and make implants an option for any patient. I am proud to introduce the 2018 summer issue of Implant Practice US, and I encourage you to check out this month’s featured articles. Whether you already place implants (you should be), are planning to, or simply restore them, you’ll find invaluable information on the latest technologies and techniques. Ara Nazarian, DDS, DICOI

Margaret Bradley, DDS Bringing out the smiles, one song at a time

D

entists study and train for years to provide high-quality dental care. While the education and experience received during those years provides a solid foundation to perform skilled procedures, every dentist knows there’s more to comprehensive care of a patient. Dentists who form relationships built on trust have patients who are more comfortable and compliant for treatment. Dr. Margaret Bradley has been practicing dentistry for 8 years in the surrounding communities where she grew up. She is in her fourth year of ownership of her family and cosmetic dental practice in Highlands, Texas. Dr. Bradley quickly puts patients at ease with her approachable personality. She finds ways to uniquely connect with them — making them smile and laugh eases any anxiety they had and instead makes a trip to the dentist a fun experience.  Dr. Margaret Bradley working on a patient

The singing dentist Growing up in a small town outside of Houston, Dr. Bradley knew she wanted a job that was enjoyable and would make a difference. She loved going to see her dentist as a child and set her heart on this career path at a very young age. She attended Texas State University and the University of Texas Dental Branch in Houston. After achieving her dream of becoming a Doctor of Dental Surgery, she never forgot why she started — to be in a positive and happy environment and create meaningful experiences for her patients.

6 Implant practice

Dr. Bradley has always enjoyed singing while she works. Patients quickly connected with this habit and almost always respond positively to the welcomed alternative of focusing on the typical noises heard in a dental office. “I have some patients who haven’t been to the dentist in years, for various reasons,” Dr. Bradley explained. “Whether I am performing a simple filling or preparing a tooth for a crown, singing makes the experience fun for everyone. I tell them there’s no extra charge for the serenade — it’s free — and I do take song requests!” Dr. Bradley has become known as “the singing dentist.” “I certainly don’t consider myself to be a professional singer, but I enjoy it, and when it can bring a smile or a laugh to a patient who hasn’t had a big smile in years — I feel like I have accomplished my goal,” Dr. Bradley said.

Finding your comfort

patients and herself. She finds confidence in using instruments that are comfortable in her hands and give her precise and repeatable performances. Dr. Bradley knows how crucial it is to have good quality materials. “Patients need to feel at ease when they come into my office, and having the right tools lets me do the dentistry with confidence,” she said. “It lets me focus on maintaining the positive energy and joy in the room while I am building the patient’s trust in our relationship.” Dr. Bradley believes it takes repeated good experiences to override negative experiences that may have caused trauma. “A dentist can be highly skilled, but with an instrument that is awkward or uncomfortable to use, it can make even a simple procedure challenging,” Bradley said. “If an instrument has the right weight and balance, is easy to grip, and is engineered to access tight areas easily, it gives me confidence in successful outcomes for my patient. My go-to is Karl Schumacher Dental instruments — they are the right fit for me in my practice.” IP

O

ur teaching institute emphasizes practical education. A hallmark example of this is our “one-on-one” mentoring program. This collaborative approach is powerful, as doctor colleagues work together with one goal in mind — achieve the best treatment outcome for our patients. Embracing digital planning in our mentoring program has proven a powerful aid to our doctors’ ability to deliver better care for their patients. Digital technology opens doors to procedures that were never thought possible. In this case, an out-of-state doctor did more than just refer her patient to our institute for treatment, but traveled with him to gain hands-on experience with our technology and perform the surgery alongside my father and me. She walked away from the case impressed with how virtual surgical planning (VSP) and cone beam computed tomography (CBCT) augment surgical and prosthetic outcomes. Most importantly, the patient walked away with an amazing result. The male patient presented at the referring doctor’s office in need of a full-mouth rehab. Treatment options included crownand-bridge work to salvage the remaining teeth with conventional restorative methodology, extraction, and dentures, or a fixed implant solution. The patient opted for implants. Our mentoring program often lowers the barrier to entry that all our patients struggle with — price. For a fraction

Riley Clark, DMD, completed his Bachelor’s degree in biological sciences at Portland State University and then moved to Cleveland, Ohio, for his DMD program at Case Western Reserve University. Shortly after graduation, he attended advanced training in anesthesia. Professionally, Dr. Clark takes great pride in optimizing clinical efficiencies and digital workflows. He spends the majority of his time in private practice doing full-mouth dental implant rehab. Dr. Clark also teaches and mentors at WhiteCap Institute. He acts as a consultant to WhiteCap Dental Lab and Milling, where he focuses on full-mouth treatment sequencing and digital workflows in preoperative procedures and final restorative procedures.

of the “retail” price, our mentoring doctors are able to offer premium implant services at a more manageable fee. To start designing the case, a PVS impression, bite registration, and a CBCT scan were taken by the referring doctor. The traditional impression was digitized by our lab, WhiteCap Dental Lab and Milling, and the STL file and DICOM from the CBCT were then merged in Dental Planning Software (DPS) (360imaging®) (Figures 3 and 4). Multiple implants were planned (Figure 1) with two thoughts in mind — first, maximize the primary stability of each implant, and second, ensure the implants were in a an ideal restorative position (Figure 2). To achieve this outcome, a digital wax-up was used (from exocad) in the planning phase. The digital wax-up was also used to finalize both full-arch temporaries — in this case,

milled polymethylmethacrylate (PMMA) (Figures 5 and 10). With both implants and temporaries planned, next we chose what guide type/ design will act as the vehicle to deliver this product to the patient. A variety of options are available for such a case. Because of our partnership with 360imaging, we were thrilled to use a new type of guide that, at the time, had a patent pending. This ingenious design features a buccal bone support, called the anatomical guide, to which all components of the case would seat to utilizing their patented diamond latch system. This leads to incredibly accurate relationships of the planned implants relative to bone and to the premade lab temporaries. Another highlight is the anatomical guide is seated from a vertical stop referenced to the natural teeth (Figures 6 and 11). This case, along with its thoughtful Volume 11 Number 2

guide design, epitomizes clinical accuracy and efficiency in full-mouth implant rehab (Figures 7-9). To summarize some benefits of the diamond latch guide: • Up to 75% smaller than comparable guides • Requires no lingual or distal tissue reflection • One point of reference for all attachments (including vertical seating piece, implant guide, PMMA) • Increased accuracy compared to other guide systems • Stronger compared to other guide systems On the day of surgery, the patient was moderately sedated via IV access and locally anesthetized with Septocaine®. We started on the maxillary arch. The guide protocol dictated that a few teeth be removed first to ensure a passive fit of the anatomical guide and the vertical stop over the remaining maxillary teeth. After those few teeth were removed, a buccal flap was reflected, and the anatomical guide was seated to the buccal plate with the help of the vertical stop resting on the occlusal surface of the maxillary teeth (Figure 11).  After the anatomical guide was fixated to the buccal plate and the vertical stop removed (Figure 12), all remaining teeth were extracted (Figure 13), leaving No. 2. Tooth No. 2 and No. 31 were deemed helpful with this case by acting as an occlusal stop and providing proprioceptive feedback to the patient during the healing phase of the implants. One novel benefit of this guide design is the additional support the buccal plate has. Often during extractions, a thin (and sometimes not so thin) buccal plate can be fractured and may mandate a change in implant position. The anatomical guide supported the buccal plate and protected the bone from excessive trauma during the 10 Implant practice

extractions. After extractions, bone reduction was done using the anatomical guide as a reference. With the teeth removed and the bone reduced, it was time to thoroughly debride the extraction sites with a curette and rotary side-cutting bur. Next, the implant guide was secured to the anatomical guide with two horizontal pins in the posterior and one vertical stop at the anterior (this is referred to as the diamond latch system). The implants were placed following the drilling protocol to maximize primary stability (Figure 14). Then the implant guide was removed from the anatomical guide, and non-hexed, temporary metal cylinders were placed in all implants. The cylinders had been prepped during the lab stage to ideally fit the PMMA temporaries. Since they were non-indexed, timing of the cylinders were visually determined based on their relative position on the lab printed analog model (Figure 15). Seating jigs were not used for this process because minor changes in implant position often exist and deem the seating jigs useless. After the cylinders were placed, bone grafting was performed in extraction sites around implants. Then dermal tissue was taken, with holes punched so it could fit over the temporary cylinders to cover the alveolar ridge. The use of dermal tissue leads to a thicker connective tissue layer after healing.  At this point, the surgical phase of the treatment was put on hold, and the temporary PMMA was seated (Figure 16). Again, the genius of this guide system is designing the diamond latch system into the PMMA (Figure 9). In this design, the anatomical guide served as a constant landmark to which all other components were referenced. 12 Implant practice

Figure 19

Minor adjustments were made to ensure ideal spacing for “pick up” material around the temporary abutments. A tissue spacer was placed between the PMMA and the dermal tissue. The “pick up” was done with a

the implants, however; and suturing was done around PMMA. This PMMA “pick up” process took about 30 minutes (Figure 17). The same procedure was repeated on the lower arch. Our “pick up” procedure followed a more traditional approach of removing the PMMA and making adjustments extraorally, while suturing procedures

14 Implant practice

were completed. Ultimately, the lower “pick up” approach was advantageous because of the time efficiency and ability to contour the intaglio of the PMMA more exactly. Occlusal adjusted and refinements were made to the fit and feel of the PMMAs (Figure 18). Postoperative CBCT scans were taken with a CS 8100 3D (Carestream Dental) to

provide a baseline and track healing (Figures 19 and 20). The patient will begin final restorative procedures in 5-7 months. What made this case predictable and even possible? The answer is the synergy of a thoughtful clinical team and powerful technology. Technology helps us execute surgical and prosthetic rehabilitation with accuracy and efficacy. Technology allows us to convert complex cases into manageable and practical cases. In fact, I would say the least stressful part of the entire case was placing the actual implants, which was historically the most stressful part of these cases when I was freehanding implant placement. From the technology, to the labs and their technicians, to the mentoring doctor, to the assistants, to the patient, this was a collaborative effort, and I would call the case a collaborative win.

CASE STUDY

Creating the FP1 prosthesis: a systematic case study Dr. Michael Freimuth discusses a technique for predictable and reproducible creation of the FP1 prosthesis Introduction As the world of implant dentistry continues to evolve, there are multiple treatment modalities to achieve clinical outcomes. The increasing use of social digital media and the Internet makes our patients exceedingly aware of the possibilities that exist. The awareness creates a perspicacious view of the results; in addition, the cost of the fullarch fixed restorations adds to the patients’ desire to be educated on their evolving expectations of treatment. There are countless articles and various franchises available offering full-arch fixed restorations and removable implant solutions. Some offer only one solution to all clinical situations, much like the track home method — cookiecutter dentistry. As a practice, clinically how do we decipher the best treatment option and material for our patients? How do we custom-build a plan for our patients? What are the clinical determents necessary? Furthermore, what steps are essential to execute and achieve the desired results? The purpose of this article is to examine creating the FP11 prosthesis (when the fixed prosthesis replaces only the crown and looks like a natural tooth) or “custom-built home” in a systematic process.

The evaluation was made utilizing clinical digital photography, digital radiographs, 2D and 3D CBCT (i-CAT) diagnostic models (maximum intercuspation position) — moreover, clinical, medical, periodontal, functional, dentofacial, and biochemical evaluations.3  The collective and collaborative decision was made to initiate treatment. Treatment began in the lower arch and was done to completion. The final result was an FP3 (when the fixed prosthesis replaces missing crowns and gingival color4). The patient was happy

with the outcome; however, she was hoping to avoid pink porcelain on the maxilla due to added lingual thickness, and there was a phonetic concern as well. Maintaining the available bone and gingival architecture was highly desirable to the patient. Instituting this plan at this clinical juncture resulted in the FP1 prosthesis as a restorative possibility. After consent was obtained, the process of commencing and developing the roadmap to achieve the desired results began. Note that it is vital to coordinate and formulate all details Volume 11 Number 2

CASE STUDY The patient was given the following preoperative medications: amoxicillin 500 mg for 7 days and dexamethasone 0.4 mg for 3 days.7 At initial assessment, the patient consented to oral sedation with a protocol prescription of triazolam 0.25 mg and hydroxyzine 50 mg. Anesthetic included 20% benzocaine topical for R/L-IA, LB. The total given was 3 cartridges of 2% lidocaine with epinephrine, 1:100,000 and 1 cartridge of 4% Septocaine® with epinephrine, 1:100,000, NADR.  Profound anesthesia was acquired.  Teeth Nos. 2, 6, 8, 9, 11, and 15 were prepped for prosthesis, and teeth Nos. 3, 4, 5, 7, 10, 12, 13, and 14 were extracted atraumatically with Luxator® (Directa Dental). Extraction sockets were debrided with curettes and flushed with chlorhexidine gluconate 0.12%. Osteotomies were performed into extraction sites, CAMLOG® implants (various diameters) were placed and torqued to 30Ncm. Cover screws were placed, and MinerOss® (BioHorizons®) allograft was placed into sockets;  BioPlugs (BioHorizons) were placed for graft containment. PMMA temporary was cemented on remaining teeth, and the temporary needed to remain for 4 months allowing for optimal HEALING. Postoperative instructions were given to the patient.

Stage 2: surgical uncovering after 4 months of healing The patient was anesthetized by placing 20% benzocaine topical for R/L- IA/L. The total given was 2 cartridges of 2% lidocaine with epinephrine, 1:100,000 and 1 cartridge of 4% Septocaine® with epinephrine, 1:100,000, NADR. Profound anesthesia was acquired. The process began with removal of the temporary PMMA prosthesis. The implants were uncovered atraumatically utilizing a CO2 laser (DEKA). The impression copings were placed, and it was confirmed radiographically that they were fully engaged. A traditional full-arch impression with additional poly vinyl siloxane (PVS) silicone heavy- and light-body wash technique was taken, and impression copings were removed. A bite registration was obtained at the desired vertical dimension.8 Healing abutments were placed, and radiographs taken to confirm complete engagement. The PMMA-milled shell temporary was modified to go over the healing abutments, then cemented in place. The patient was given postoperative instructions and scheduled for removal of the remaining dentition. The impression and clinical digital photographs were sent to the laboratory along with the written script. 20 Implant practice

Stage 4: prosthetic phase after 4 weeks of healing The patient returned to the office, and the PMMA screw-retained temporary was removed. Impression copings were placed, and radiographs taken for confirmation of full engagement. Final implant level impressions were made with PVS material using a heavy- and light-body wash technique. The temporary was reinserted, and the access opening was filled with PVS material for easy retrieval. The patient was scheduled for final delivery in 4 weeks.

Final appointment The temporary was removed, and the final prosthetic torqued to 30Ncm based on manufacturer. The final access openings were filled with Teflon tape, Bisco’s All-Bond Universal®, and VOCO GmbH composite, and the final occlusion was equilibrated. The postoperative instructions were given to the patient, along with a water flosser and oral hygiene instructions, and she was scheduled in 2 weeks for evaluation as well as her maintenance plan.

Discussion Of course, there are a myriad of treatment possibilities for the terminal dentition.9 When to institute treatment is a collaborative effort that involves the patient and the treating doctor. Prognostic understanding and educating the patient are vital to achieving predictable clinical outcomes. The aforementioned treatment was initiated prior to loss of anatomy, and the patient desired to have a more functional and esthetic outcome. Furthermore, without extensive breakdown, the need for advanced bone grafting procedures can be avoided, and the aforementioned “key” implant positions10 can be placed. Prosthetic-wise as clinicians, we can bypass cantilevers and large pontic spans,11 resulting in less stress in implants due to tension being placed down 24 Implant practice

the long axis of the implant rather than sheer forces. This allows for less crown height-toimplant height ratio, which creates less force on the implants. Consider this: Ovate pontic spaces with short spans are much more easily maintained due to crested bone architecture and are easier for the patients to preserve.

Conclusion Predictable and reproducible creation of the FP1 prosthesis is an attainable treatment module when the plan is initiated prior to excessive anatomic loss. Through taking clinical digital photographs, 3D scans, radiographs, comprehensive records, impressions, and thorough clinical examinations to screen patient, the treatment can be tailored to the patient. Considering the patient’s desire for his/her clinical outcome and determining the most effective way to educate him/her on the treatment path will increase acceptance. Although there are more clinical stages and patient visits, it has been the author’s experience that the patient’s expectations are met and often exceeded.  IP

Rehabilitation of an atrophic maxilla with guided flapless implant surgery and immediate loading Dr. Andoni Jones discusses the treatment of an edentulous patient using 3D planning to avoid complex grafting procedures

T

he rehabilitation of a patient with atrophic jaws can be challenging for the dental team. Costs, healing periods, morbidity, and complications can also be elevated for the patient. However, cone beam computed tomography (CBCT) and 3D implant planning software allow us to treat these patients in a less invasive and a more predictable way. Traditionally, treatment of patients with atrophic jaws requiring implant therapy involved complex grafting procedures and extended healing periods. Many patients rejected these treatment modalities due to their high complication and morbidity rates and costs. Nowadays, we are able to treat many of these patients in a much quicker, less invasive, and safer way by using 3D technology to place our implants in a safer way. Since computer-guided implant surgery was first introduced in 2002, digital technology has evolved into a very accurate tool. Inaccuracies in implant placement are considerably reduced, benefiting to a great extent those patients with atrophic jaws, in whom a very precise use of that limited bone for implant therapy is paramount. This article will discuss this approach and present a case report of a 56-year-old woman with an edentulous maxilla who wished to get a fixed restoration. The lack of teeth and use of a complete denture for 25 years had resulted in a considerable bone resorption. She was treated using 3D planning and a surgical guide to place five implants that allowed us to transform her complete denture into an immediate fixed

temporary restoration, and 3 months later she was restored with a permanent metalceramic fixed restoration.

Introduction The treatment of edentulous patients with dental implants has proved to be highly successful, and a paradigm shift in the management of patients with complete dentures (Dudley 2015). The loss of natural dentition along with the use of complete mucosa-borne dentures is related to different degrees of maxillary atrophy, on occasion making it very difficult to deliver fixed rehabilitation with implants. In the presence of an atrophic maxilla, different surgical techniques have been described for the surgical correction of such deficiencies to enable implant therapy (Sorní, et al., 2005). Sinus lifts, autogenous block grafts, and guided bone regeneration

procedures have been well described in the literature with good results. Nevertheless, it is a well-established fact that these complex procedures entail a high risk of surgical and postoperative complications such as infection, wound dehiscence, bone graft resorption, or damage to adjacent anatomical structures (Boffano and Forouzanfar 2014; Faverani, et al., 2014). Cost, the need for general anesthesia, a second surgical site for bone harvesting, number of surgeries, extended healing periods, and long treatment time — as well as the previously mentioned complications — are factors that negatively impact on patient acceptance for these treatment modalities. Since computer-guided implant surgery was introduced in 2002, the advances in 3D diagnosis and surgical and prosthetic planning allow the dental team to treat many

Andoni Jones, BDentSc, graduated from dental school in Bilbao, Spain, in 2010. He worked as a general dentist for 3 years, completing his postgraduate implant training in the same university before moving to Ireland in 2013. He currently works in private practice in Dublin, Ireland, where he carries out a lot of oral surgery and implant dentistry. Planning and executing implant treatments from surgery to restoration, Dr. Jones is a big advocate of 3D planning software and computer-guided surgery, which he uses from single to full arch implant supported rehabilitations.

edentulous patients in a simpler and safer way (Ganz 2015). With this technology, clinicians can accurately transfer the preplanned position of the implants from the 3D software into the patient’s mouth, having the advantage of predictably performing minimally invasive (flapless) surgery with immediate load in many cases. With 3D implant planning software, it is possible to integrate the patient’s surgical and prosthetic treatment into one single platform. Having the restorative plan on the computer screen before placing the implants is a key point in the diagnosis and execution of a prosthetically driven implant treatment (Mora, et al., 2014). The transfer of CBCT images to 3D implant software considerably improves treatment planning, ensuring controlled implant insertion by the means of guided surgery. Doing this allows a surgical template to be created that will guide the implants into the right position, depth, angulation, and orientation. Better use of the patient’s existing bone can be made, thus considerably reducing the amount of patients that require complex reconstructive surgeries before implant therapy.

Case report A 56-year-old woman, medically fit and with no allergies, wanted to replace her complete upper denture with a fixed implant restoration. On initial examination, photographs and an OPG were taken. This radiograph revealed very pneumatized sinuses, Volume 11 Number 2

with practically no available bone for implants in the posterior regions (Figures 1 and 2). The current complete denture met with the esthetic criteria (incisal edge, midline, smile line, lip support), so it was used as a reference to prosthetically guide the implant planning. To transfer her denture — and with it, the position of the teeth — into the 3D planning software (NemoScan by Nemotec, Spain) a “dual scan” protocol was utilized. This involved inserting eight gutta-percha markers into her denture: four in the buccal flange and four in the palate. A CBCT was taken with the patient wearing the denture, and a second CBCT was taken of the denture alone. This allowed the 3D-planning software to superimpose the denture onto the maxillary CBCT, thus showing the bony architecture, the desired position of the future teeth, and the shape of the soft tissue (this being the gap between the denture and the bone) in one single screen. A key step is to ensure the perfect adaptation and stability of the scanning appliance (in this case, the patient’s denture) before taking the CBCT (Figures 3-7). After careful examination of this CBCT, a surgical plan was made to place five implants where bone was sufficient, but still obtaining proper prosthetic support, combining two anterior implants with three posterior ones, two of which were tilted to avoid the sinus. This option, as well as alternative grafting techniques, was explained to the patient, and the decision was made to continue with this original plan.

A mucosa-borne surgical guide was prepared from this 3D planning and used to place the implants in a flapless way (Figures 8 and 9). The patient took amoxicillin 2000 mg 2 hours before the surgery, and articaine was used for anesthesia. The surgical guide was fitted onto the maxilla, checking its perfect adaptation by direct visualization and tissue blanching. It was fixed to the maxilla with three titanium pins, and once in place, osteotomies as well as implant insertion were completed through the guide. All implants achieved an insertion torque in excess of 40Ncm, and over 66 ISQ. After removing the surgical guide, another CBCT was taken to ensure all implants were correctly placed between the bony housing, allowing also to make a comparison between the final implant position and the 3D planning (Figures 10 and 11) (Table 1). Multi-unit abutments were connected to all implants (Figure 12), using 30° angulated abutments on the tilted implants to correct the emergence and to keep it in the prosthetic corridor. The patient’s conventional denture was converted into a screw-retained temporary fixed restoration (Figures 13 and 14) using titanium abutments and a pick-up technique. The patient was given a postoperative prescription of ibuprofen (400 mg) for analgesia and a chlorhexidine 0.20% mouthwash, and instructed to keep a soft diet for 3 months. Healing was uneventful, and 3 months after implant placement, the Implant practice 27


CONTINUING EDUCATION temporary prosthesis was unscrewed to find all five implants well integrated. The final prosthetic phase was to fabricate a screwretained metal-ceramic fixed restoration, which met with the patient’s esthetic and functional needs (Figures 15-17).

Discussion In a society where time is so important, more and more patients are looking for immediate results, reluctant to go through longer and more uncomfortable treatments. The possibility of performing the surgical and prosthetic techniques of implant dentistry in the same clinical visit represents a very effective approach that significantly reduces the treatment time and dramatically improves the patient’s quality of life (Cannizzaro, et al., 2008; Tarnow, et al., 1997). Fewer hours spent chairside make the experience more pleasant for the patient and less tiring for the clinician. Flapless surgery is also a very effective way of treating patients with a fear of surgery. With no need to raise a flap or carry out suturing, postoperative pain and swelling are greatly reduced, as are recovery times (van Steenberghe, et al., 2005). Intraoperative complications and bleeding can also be minimized. Peri-implant tissues also benefit from flapless surgeries, as a quicker seal around the implants is possible from day one (Maló, et al., 2007). Current scientific evidence in implant dentistry dramatically changed Brånemark’s original guide for osseointegration. Immediate loading is a well-documented approach, with success rates similar to those of conventionally loading techniques (Salama, et al., 1995). For successful immediate load protocols, a number of factors must be considered. First, a careful examination of the radiologic images for implant planning is key. New computer-assisted three-dimensional image technologies have revolutionized this field, allowing the implant surgeon to study the different possibilities for implant

Figure 12: Multi-unit abutments connected 28 Implant practice

number and position for each patient in a virtual model. This way the most favorable surgical protocol can be established for each case (Marchack 2007). Bone density can also be accurately measured in order to ensure that immediate load will be predictable (Shahlaie, et al., 2003). Another key point is implant selection. Implants with a roughened surface that will improve osseointegration, and a macro geometry that will allow high insertion torques and good primary stability is essential for immediate load. These implants must always be splinted to provide favorable

absorption and distribution of the load and to reduce any micromovement during the healing phase. Avoiding micromovement is paramount if immediately loaded implants are to osseointegrate, so the patient has to keep to a soft diet for at least 6 weeks, progressively introducing soft chewing after this period elapses. It is well documented that an edentulous maxilla can be immediately loaded and restored with a fixed prosthesis using as few as four implants placed in strategic positions. The “All-on-four” technique that was first described by Maló, et al. (2003)

advocates the placement of two vertical implants in the anterior region and two more implants placed mesial to the sinus in a 30°-45° angulation. When implant placement in the posterior maxilla is not possible in a conventional way due to sinus pneumatization, this technique offers a very effective way of using the existing bone in the premaxilla to anchor the implants while still reducing distal cantilevers. Scientific literature also supports that tilted implants have similar success to axially placed implants when they are splinted (Aparicio, et al., 2001). Thus, tilted implants in the premaxilla present a very safe and predictable outcome to sinus augmentations. An essential advantage of computerassisted techniques is the precision that the implants are placed with. This accuracy can be measured by comparing the 3D planning with the final surgical position and angulation of the implants (Widmann and Bale 2006). It has been demonstrated that computerassisted implant placement is more precise than manual insertion (Brief, et al., 2005). However, it is also necessary to have a minimum safety margin of 1 mm from important anatomical structures, since some error can be accumulated from the transfer of the radiologic images to the 3D software and the positioning of the surgical guide. Despite this, it is the opinion of this author that computerassisted surgery should be considered the safest way of placing implants, since it is the technique least influenced by human error. One study showed that an experienced surgeon can have an average of 6.1 mm deviation when drilling an osteotomy manually, compared to an average of 0.5 mm when using computer-guided surgery (Schermeier, et al., 2001). Another study compared implant selection and planning between conventional radiographs and 3D software, and the length of the implants was increased in 77.7% of the cases when using the 3D software (Siebegger, et al., 2001). Longer, wider implants increase the contact surface between the implant and the bone, which is a very important factor in immediate load Volume 11 Number 2

protocols, where functional load of these implants happens before actual osseointegration occurs (Sanna, et al., 2007). In order to achieve an accurate transfer of implant position from the virtual platform to the oral cavity — and therefore achieve a successful guided surgery — a scrupulous protocol must be adhered to. The clinician should ensure that all steps, from the scanning of the patient to the surgical placement of the implants, are carried out meticulously. The scan appliance must be perfectly adapted and thoroughly assessed — relining it intraorally if necessary — before taking the CBCT. From here, the accuracy of the procedure is determined by the surgeon’s ability and proficiency with the technology, the precision that the surgical guide is made with, the compatibility and tolerance of the surgical drills and transfers, and the correct

fitting and fixing of the surgical drill. It must not be forgotten that the stability and position of the surgical guide has to be checked during all steps of the implant surgery.

Conclusions By reducing the number of surgeries to one, implementing immediate load protocols, and decreasing patient morbidity and complications with a minimally invasiveness philosophy, both the clinician and patient can benefit from more predictable and safer implant dentistry. Three-dimensional images help the implant surgeon plan the number, location, diameter, and length of the implants. The surgical stent guides the surgery, enabling the correct and precise placement of the implants to be able to load them with a fixed restoration at the same surgical session. IP

Digital smile design in implant dentistry Dr. Rory McEnhill examines the impact of digital technology on clinical dentistry and the patient experience

W

ith the rising tide of the digital workflow in all aspects of dentistry, the benefits of incorporating digital planning and digital smile design (DSD) into daily practice are considerable. The first and most important aspect is to motivate and stimulate the patient into making an emotional connection with the treatment plan. In cases where a considerable amount of treatment is required, the ability to offer patients a very clear indication of how their final prostheses could look is a very powerful tool. In addition, being able to fabricate provisional healing prostheses designed with digital smile design protocols allows the patient to have excellent esthetics from the start of treatment. In normal circumstances, the modification of a temporary denture into a healing bridge provides lessthan-perfect esthetics and potential patient dissatisfaction.

Great expectations Patient esthetic expectations are becoming increasingly stringent. With better education and more exposure to dental case reports on social media platforms, patients — quite rightly — wish to obtain a result that is realistic and lifelike. In the past, full arch implant cases would run in a linear

fashion, starting with tooth removal, implant placement, and final prostheses provision. Implants would be placed where the bone was ideal, and the final bridge would be manufactured to suit. However, with the onset of DSD, we can work backwards from an ideal esthetic result and assess where implants need to be placed to facilitate this ideal result. Using facial landmarks, we can ascertain ideal tooth spatial dimensions and confirm optimal prosthetic envelope for the teeth. This allows us to decide on the breadth of smile, the smile curvature relative to the lower lip, and the position of the upper teeth relative to the wet border of the lower lip. Once the

2D planning is complete, digital scans of the upper and lower arches are taken, and the STL files sent to the laboratory. From these, the 3D planning commences, and a digital wax-up can provide a diagnostic template that can be used to carry out a mock-up intraorally. Digital videos can be used to assess esthetics, function, and phonetics. Following mutual agreement regarding the esthetics, implant planning can then begin. The CT DICOM file and the 3D planning STL files can be superimposed, and this allows the clinician to ascertain where the implants are best suited to enable the dentist to fabricate the healing/permanent prostheses. From here, the surgical guides

can be milled and can offer partial or full surgical guidance.

Case study In this case, this patient presented with a partial denture that was uncomfortable, and its retention was compromised by the remaining mobile maxillary teeth. The patient was unequivocal in her demand that she should have a full arch implant solution as she did not want anything that was removable or to have palatal coverage. Volume 11 Number 2

Consequently, the implant planning stage considered six strategically placed implants, providing effective support for an immediately loaded milled healing bridge. The patient attended for a number of presurgical hygiene appointments while the DSD planning was taking place. The surgical appointment involved the positioning of a pre-surgical guide. The remaining teeth were used to locate a guide that allows us to precisely drill pilot holes. The teeth were removed atraumatically.

Following the removal of the teeth, the osteotomy surgical guide was placed into position, and the implant sites were prepared using guided surgery MegaGen osteotomy burs. A silicone matrix was prefabricated to ensure that the upper bridge was in the right position relative to the lower arch. Following this, multi-unit abutments were chosen, with 3 mm angled abutments (29 degrees) placed on the distal implants, while 3 mm straight abutments were placed on the anterior implants.

Digital dentistry: the benefits 1. Digital smile design can offer patients a clear indication of how their final smile will look. 2. Being able to visualize the entire treatment, step by step, provides excellent esthetics right from the start. 3. Digital videos can be used to assess esthetics, function, and phonetics. 4. Never underestimate the power of conventional techniques and methods with good quality lab work, but allow yourself to open up to the possibility of more accurate restorations and faster treatment times.

other finishing materials such as ceramics and composites. In addition, it is easy to mill and polish, which expedites laboratory turnaround, allowing the restoration to be fitted more expediently. Patients notice the decrease in weight of the bridge, while other attractive qualities such as no metal taste and no thermal or electrical conductivity are appreciated. In terms of the cantilever of the molar teeth on the bridge, Maló, et al. (2003; 2005), suggest that if there was an anteroposterior spread of 10 mm between the mesial and distal implants, then the cantilever can be 20 mm. In the maxilla, the cantilever is well within the remit as the screw holes are present at the UL5 and UR5. To provide further protection, a nighttime splint will also provide even and equitable occlusal forces. In addition, tooth wear will be limited by the wearing of a splint.

Final esthetics With regard to the final esthetics, I feel that the result is a very natural one. The incisal edges of the teeth mimic the lower

labial curve very nicely. The subtle graduation in colors in the crown’s esthetics with lovely incisal edge translucency adds to the overall result. Digital dentistry is the future, but it is also the present. While conventional techniques and methods aided by quality laboratory work will always provide top quality results, digital dentistry allows us to expedite treatment time and more accurate restorations — not to mention greater patient acceptance.

were then picked up in hard cure acrylic inside the milled bridge. Following 3 months of hard and soft implant healing and integration, a Pekkton® bridge (anaxdent North America and Cendre + Metaux) was fabricated. The Pekkton bridge is an interesting material to use for full arch bridgework. It has a large number of benefits. It is metal-free, biocompatible, contains low water absorption, and high strength-to-weight ratio. Another property that is very attractive in an implant bridge is the compressibility or the shock absorbency of the material. Due to the loss of proprioception in the articulatory apparatus, this is a welcome addition as it gives a little more flexibility in occlusion. This would be especially important in a full mouth case, where the author’s normal protocol is a porcelain bridge in the maxilla with a hybrid acrylic or composite bridge in the mandible. However, with Pekkton bridges, there is the potential to go for porcelain in both arches. Other attractive features with this material include its flexibility and compatibility with

SMALL TALK

A critical distinction: problem solver versus people developer Dr. Joel C. Small offers a technique for creative problem-solving

I

often encounter doctor clients who are frustrated by their team’s lack of ability to achieve a pre-defined, desired result. The scenario goes something like this: Coach: I hear that you are frustrated. Give me more detail. Doctor: Okay. Well, no matter how many times I tell my staff what I want them to do, they are unable to consistently get it right. Even worse, they are constantly coming to me with problems that they should be able to manage. It seems as if they can’t make decisions on their own. I’m too busy to keep repeating myself, and I get frustrated when they come to me needlessly to solve every simple problem. I’ve tried everything I know to change this situation, but to no avail. Coach: Everything? Have you tried becoming a “People Developer”? Doctor: I don’t know what that means. Tell me more please. Any coach, in any industry, will recognize this scenario because the premise knows no boundaries. The good news is that even though the problem is universal, so is the solution. The answer lies in understanding the distinction between a “problem solver” and a “people developer.” The doctor in the above scenario is a problem solver. By this I mean that he/ she issues directives without tying them to the foundational principles of the practice. Secondly, he/she has failed to create a practice environment that is conducive to ongoing personal development. How do I know this to be true? Simple. If the doctor had been a “people developer,” he/she would not be plagued with these problems. As we shall see, it is the doctor, not the staff, who has created the problem.

Almost invariably, problem solvers fail to define the purpose of their directives and how the specific purpose correlates with the fundamental practice purpose and values. This is assuming that the doctor has even defined and shared these ideals with the staff. This lack of communication leaves a void that is filled by each team member’s own interpretation of purpose. Purpose is a strong determinant of action, so we can only imagine the confusion and frustration when a team with varying interpretations of purpose tries to achieve a common goal. Furthermore, problem solvers will always be plagued with never-ending questions from their team. Frankly, the problem and solution revolves around our expectations of our staff. Do we expect them to be helpless? Are we okay with their unwillingness and apparent inability to answer even the simplest of questions? I would expect that even the most devout problem solvers would say “No!” and yet they fail to see that they impose the very environment that promotes these forms of learned helplessness. The more we continue to answer questions, the more we become entrenched in the problem solvers’ mentality, and the more our staff is willing to abrogate their creative ability to solve problems on their own. The answer is for us to commit to developing these God-given skills in those who serve our cause. We do this by seeking their input to creative problem solving. We do this by becoming people developers. I am reminded of the old Chinese proverb, “Give a man a fish, and you feed him for a day. Teach a man to fish, and you feed him for a lifetime.” And so it is with people developers. We must first believe that someone is able to fish, or

in this case, solve problems on his/her own. Believing that something can be done will eventually become an expectation that it will be done, and expectations have been shown to be powerful self-fulfilling prophesies. Our team looks to us for answers when we fail to develop their problem-solving skills. If we find ourselves in this situation, here’s a simple solution. First, let the team know that you will be seeking their input to problem solving; then immediately quit answering questions. When someone comes to you seeking a solution to a problem, tell him/her that you have a solution, but you would like to hear their solution first. In many cases, that staff member’s solution will work quite well or will require minimal adjustments. Always make a clear correlation between the solution and the guiding practice values and purpose. Over time, staff members will realize that you will not be answering questions without their input. More importantly, they will realize that their solutions are good solutions, and with your support and encouragement, they will begin to solve problems independently within the confines of the practices purpose and values. It is important at this juncture to be clear regarding decisions that you feel require your input. Surprisingly, as the people development process progresses, you will find that your input is required less and less. Fundamental to the people development process is a willingness by the leader to encourage input, acknowledge it when received, and affirm its value. People developers will tell you that they have grown to rely on their staff’s problemsolving capabilities. I can tell you that I have personally observed very positive changes in practices that have adopted a peopledevelopment mentality. IP Volume 11 Number 2

Recover, repair, and heal from super stress with BrainTap® Sandra Marlowe discusses how to nurture a relaxation response in everyday life and the dental office

N

ighttime sleeplessness may be a result of our minds and our bodies combined response to stress. A study in International Journal of Psychophysiology pointed out Chinese researchers’ discovery that our bodies are primed to stay awake when we perceive threats, and nighttime stress may amplify this response. Our bodies are responding to stress much like our ancestors did when they faced nighttime threats from predators — our brain thinks we’re in danger and keeps us on high alert, diminishing the possibility of a good night’s sleep. Most people experience “super stress,” in their everyday lives, so the brain has to cope by generating high-intensity brain waves, which overpower calming brain waves, especially at night. Once your brain becomes used to this hyper alert state, it can become very difficult to wind down again. Super stress often manifests in disorders such as ADHD, obesity, diabetes, insomnia, headaches, and high blood pressure, to name but a few. To obtain a state of homeostasis (balance) for recovery, repair, and healing to take place, try the following five simple steps to optimal health.

Tip No. 1: Breathe deeply Deep breathing sends a message to your brain to calm the body. Detrimental stress responses — such as increased heart rate, increased hormone production, and high blood pressure — all decrease as you breathe deeply to relax. Just a few minutes of deep breathing can calm you and put the body back into recovery mode. For this reason, every audio session in our BrainTap® Library includes deep, relaxing, guided breathing designed to bring your body to ultimate relaxation.

To obtain a state of homeostasis (balance) for recovery, repair, and healing to take place, try the following five simple steps to optimal health. 1. Breathe deeply. 2. Focus on the moment. 3. Reframe the situation. 4. Keep your problems in perspective. 5. Practice mindful meditation and visualization.

Sandra Marlowe has authored, co-written, or ghostwritten eight self-improvement books, including an award-winning bestseller. She has earned a Pushcart Prize nomination in literature. She regularly writes and speaks on topics related to brain health and self-development.

Once you enter this “relaxation response,” the brain sends out neurochemicals that neutralize the effects of stress on the body, allowing you to change your reactions to the stressful events going on around you. The sessions offered in the BrainTap Library are designed to help you reach the relaxation response.

state of deep rest that changes the physical and emotional responses to stress. Once you enter this “relaxation response,” the brain sends out neurochemicals that neutralize the effects of stress on the body, allowing you to change your reactions to the stressful events going on around you. The sessions offered in the BrainTap Library are designed to help you reach the relaxation response. In 20 relaxing minutes a day, you can reduce or eliminate brain fog and negative mind chatter, have more energy, relax and develop positive sleep habits, rid yourself of unwanted habits and behaviors, gain memory and focus, and improve the quality of your life. Fortunately, your BrainTap headset produces the relaxation response, which can help your brain relax and feel safe — giving your body precisely what it needs to get back in balance and reverse the effects of stress on the body. The BrainTap headset will help dental patients before, during, and after dental procedures as well. Regular use of BrainTap Technology will help rebalance your brain wave activity, allowing your brain to relax, rejuvenate and reboot itself — helping you to sleep more deeply and awaken refreshed. So, the next time you’re wide awake and feeling the stress, take comfort in knowing that your brain is doing exactly what evolution taught it to do, but you can take back control and ease into a great night’s sleep by using the BrainTap headset.

Tip No. 2: Focus on the moment When you are stressed and anxious, you may be worried about the future or regretting a past action. This can cause immense amounts of stress from which our bodies need recovery time. One way to lessen this type of stress is to bring yourself back to the moment. If you’re walking, feel the sensation of your legs moving your body. If you’re eating, focus on the taste, the smell, the sensation of the food you’re consuming. If you’re relaxing, be mindful of the heaviness of your limbs and the deep, rhythmic sound of your breathing. Rather than seeing only the negatives, focusing on the moment offers you a space to think differently about stress and respond in a more appropriate manner without past regrets or future worries.

Tip No. 3: Reframe the situation When you are stressed or overwhelmed, focus on a positive thought. (This is called “reframing” the situation.) It’s not as hard as you think. Look at the same situation in a new way that highlights the possibilities. Viewing our stressors as opportunities can help us stop feeling trapped and reduce 40 Implant practice

the physical effects of stress on our bodies almost immediately. Ways to reframe the situation 1. Look at what is actually stressing you. 2. Consider what you can change, if anything, about the situation. 3. Look for the positives. 4. Find the humor.

Tip No. 4: Keep your problems in perspective Don’t stress too much on a specific problem. It’s important to remind ourselves of the positives in our lives — we woke up this morning; we can see; we can walk; we have family and friends to support us. It might seem a little silly at first, but the next time you’re feeling stressed, consciously make the effort to think about the things you’re grateful for. This can be a surprisingly easy way to reduce the stress in your life.

hen challenging fixed-hybrid implant failures happen, a prosthesis emergency could result. In the past, replacing the prosthesis was the only option available as it was virtually impossible for the existing prosthesis to seat passively in the altered position of the screw-retained components at the replacement implant site. Zest Dental Solutions recently introduced the LOCATOR F-Tx Fixed Attachment System, revolutionizing the way clinicians think about fixed fullarch restorations by not requiring screws or cement to affix the prosthesis. The unique design of the LOCATOR F-Tx System also allows it to be the only immediate solution on the market today to rescue a fixedhybrid prosthesis when an implant fails. The unique design of the LOCATOR F-Tx Fixed Attachment System includes a

novel “snap-in” attachment that is picked up chairside, ensuring a passive fit, while working in harmony with existing screwretained abutments, and saving both clinicians and patients substantial time, money, and frustration. Zest Dental Solutions President and CEO Steve Scheiss, explains, “Now clinicians can not only offer a fixed full-arch restoration without using screws or cement to affix the prosthesis, they can also use the same technology to save a patient’s prosthesis when a fixed-hybrid emergency occurs. LOCATOR F-Tx arms clinicians with one product that provides multiple treatment solutions for fixed restorations.” “LOCATOR F-Tx represents another paradigm shift from Zest that allows clinicians to provide innovative treatment solutions to their edentulous patients,” Scheiss added.

Zest Dental Solutions is a global leader in the design, development, manufacturing, and distribution of diversified dental solutions for a continuum of patient care from the preservation of natural teeth to the treatment of total edentulism. The company’s product portfolios consist of Zest Anchors, Danville Materials, and Perioscopy with global distribution through OEMs, dealer/distributor networks, as well as a domestic retail sales operation for the Zest Anchors Portfolio.

PREAT Corporation introduces the Bidra Conversion Smart Polishing Cap PREAT Corporation has introduced a new and innovative tool for all implant professionals: the Bidra Conversion Smart Polishing Cap, a must-have for your next conversion from a removable to a fixed prosthesis. Existing polishing caps protect only the inside of the coping, not the outside. Avinash S Bidra, DDS, MS, FACP, Director, UCONN Post-Graduate Prosthodontics, designed this innovation with the dental professional in mind. With an extended metal rim, the Bidra Conversion Smart Polishing Cap fully protects both the inside and outside of the metal coping, preventing damage to the coping during pickup, trimming, polishing, and finishing the prosthesis. External rough areas attract food, plaque, and bacteria and may lead to soft tissue inflammation and bone loss around the implants. Eliminate the headaches with the easy-to-use Bidra Conversion Smart Polishing Cap from PREAT Corporation. For information, visit www.preat.com or call 800-232-7732.

Karl Schumacher Dental launches comprehensive suite of regenerative products Karl Schumacher Dental, LLC, marks its 70th year in business with the debut of a new family of regenerative products that includes allograft, xenograft, synthetic, collagen membranes, and dental wound dressings. The allograft particulate, putty, and paste are used in oral surgical applications, socket preservation, periodontal defect regeneration, dental implant bone regeneration, sinus lifts, and ridge augmentation procedures. It contains 100% human demineralized bone matrix and BMP-2, free from additive excipients required in other products for improved handling. All allograft tissue is recovered in the United States under the most stringent screening and testing protocols. The xenograft particulate is an osteoconductive, porous, anorganic bone mineral with carbonate apatite structure derived from porcine cancellous bone. The synthetic putty is a synthetic mineral-collagen composite bone graft matrix for use in bone repair during oral surgeries. Karl Schumacher’s collagen membranes and dental wound dressings offer the same high-quality as other Schumacher products. The membranes are ideal for guided bone regeneration, socket preservation, alveolar ridge reconstruction, and augmentation around implants placed in immediate extraction or delayed extraction sockets. When wound dressing is needed during dental surgery, the foam, plug, and tape dressing work in moist environments, controls bleeding, and protects the wound from further injury. For more information, visit www.karlschumacher.com.

ASI touts its White Silk handpiece tubing ASI’s White Silk handpiece tubing is now the standard instrument tubing on its dental systems. Because this new tubing is lighter, softer, and smoother, it provides cling-free use. When a handpiece is removed from the holder, it glides smoothly across neighboring tubing. The silky smooth texture reduces the risk of tangling or accidentally dislodging other handpieces. All new ASI dental systems in 2018 will be equipped with white silk handpiece tubing.

Ultradent Products, Inc., celebrates 40th anniversary

New product from Denali Corporation: Jazzy™ Dual Cure Acrylic Resin Denali Corporation, Hanover, Massachusetts announced Jazzy™ Dual Cure Acrylic, a dual cure acrylic resin for implant verification guides, abutment positioning, PFM copings, border molding, bridge repositioning, and many other operatory and lab uses. Jazzy™ is intended to replace the tedious, old powder and liquid “salt and pepper” technique. It allows for continuous addition of material with a self-cure time of about 1 minute and cures on demand with all wand-type curing lights in 20 seconds or less. For PFM copings and other castings, Jazzy™ burns out completely with no residue. Jazzy™ comes in a syringeable form that is easy to apply and is safe with no exothermic buildup — no pain. Jazzy™ also eliminates the use of dental curing ovens needing setting times of 5 to 40 minutes. Dental appliances can be fabricated in a matter of only a few minutes, compared to the 20-30 minutes for current materials. Jazzy™ bonds between layers, flows into place, and can be finished to a lustrous surface. Jazzy™ eliminates odor from open bottles of methyl methacrylate and offers enormous time and convenience advantages over other acrylic products, including no waste, no spills, and no clean-up.

Surviving implant failures Dr. Justin Moody reflects on how implant failures affect both the dentist and the patient

N

o one ever wants to hear the hygienist or the patient say, “Doctor, I think we have a problem with this implant,” yet if you place enough dental implants, you will indeed end up having this discussion. Complications and failures are part of the business and will happen to any dentist who places enough of them — the law of averages always wins. But why? We have taken all the precautions, are well educated, and the procedure went great, yet there is still an issue. If you really think about what we are asked to do with dental implants, it’s a small miracle that any of them survive. Being asked to place a cold piece of titanium metal into the dirtiest, most bacteria-infested part of the body, where motion occurs and foreign objects are placed all day long, is a lot to ask. I always tell my patients that although dental implants enjoy one of the highest success rates of any type of dental procedure, there is always the risk of complications and failure. How you handle these complications is your key to surviving the event and maintaining the positive relationship with the patient, but more importantly, we need to avoid giving implant dentistry a bad name. In my opinion, criticizing another dentist’s work when you see an issue is not only rude but also shameful; you have to believe that on that patient’s treatment day, the dentist was doing his/her very best. Will some patients just not understand? Yes, but in my experience, I have noticed that if you are honest with them and have a plan to resolve the issue, most will take comfort in that, and you may actually build more trust with the patient over how you handle the situation. There are three keys to surviving implant failures — first is education. You need to have a solid understanding of the science

Justin Moody, DDS, DICOI, DABOI, is a Diplomate of the American Board of Oral Implantology and of the International Congress of Oral Implantologists, Fellow and Associate Fellow of the American Academy of Implant Dentistry, and Adjunct Professor at the University of Nebraska Medical College.

Figure 2: Uncovering the site reveals nearly complete fibrous tissue encapsulation of the dental implant

Figure 3: When an implant fails, it almost always takes good bone with it, leaving a defect that will need to be rebuilt and managed

and clinical procedures involved with good implant treatment. Second, you need to know your patient and the risk factors associated with this case. Many of our complications can be avoided by just getting to know the patient’s medical and dental history. And third, it’s about only setting realistic expectations. I am not necessarily talking about esthetics but about the fact that somehow the public has the perception that all dental work should last a lifetime, and if it doesn’t, they are upset and expect the resolution to be free of charge. Simply telling your patients that nothing in dentistry is forever can go a long way, especially if you plan to practice for 30 to 40 years. Don’t let a dental implant failure derail your career. I have seen too many dentists back away from implant dentistry after having

Figure 4: No one likes to see the implant on the tray, but an understanding of why it happened will make it a valuable learning experience

a negative outcome. Remember that we learn more from our failures than we ever do from our successes. Take a step back when something like this does occur, be a detective, find out what really went wrong, and then fix the situation in such a manner that you can lower the risk factors and get a good night’s sleep. Always do the right thing; it’s just that easy. IP Volume 11 Number 2
