Anterior Tooth Replacement Made Easy: A Conservative and Predictable Direct Technique

Often, patients and referring orthodontists have a preconceived idea that a cosmetic solution to a problem, such as congenitally missing lateral incisors, will be a very complex and clinically involved challenge. Fur­ther­more, it is often thought of as being a very expensive ordeal to solve. In many cases, when clinically indicated and if the appropriate materials and techniques are employed, nothing could be further from the truth! The following article will focus on a real-world clinical example that demonstrates how a conservative and predictable direct restorative technique can be used to successfully treat a case involving congenitally missing lateral incisors.

Diagnosis and Treatment Planning

Rachel, a 32-year-old mother of 4 and a third-year law student, had been struggling with congenitally missing lateral incisors since the removal of her braces at age 18 years. Her oral health was excellent. She has no other dentistry in her mouth. Her gingival and bone health were both very good.

In reviewing her intraoral photos (Figures 1 and 2) together at her initial consultation, Rachel had many concerns regarding her smile. She felt that her smile looked “run down,” and she complained of food getting stuck under the lateral incisor restorations. Furthermore, she stated that she disliked replacing the lateral incisor restorations every year because they would fall out at the worst times, and the only thing she could count on is that they would look different every time the dentist replaced them. To add to her distress, Rachel had never been happy with the different restorative/aesthetic outcomes. Rachel’s other concern during our initial discovery was that tooth No. 9 looked disproportional to No. 8 due to the poorly executed composite on No. 9. Also, gaps in the lower anterior teeth and the nonharmonious gray, white, and yellow appearance of her teeth were also issues she that she desired to have addressed.

It was determined that Rachel was not a candidate for an implant to replace tooth No. 7 due to space constraints between the central incisor (tooth No. 8) and canine (tooth No. 6) roots. An implant in the area of No. 10 was possible and would be considered in the future; however, Rachel was constrained by time and money at this point in her life.

Given Rachel’s time and financial constraints, and considering her desire to do something more permanent in hopes that her financial situation would change in 3 to 5 years, a conservative mid-range plan was presented to Rachel addressing all of her concerns. An intercoronal fiber-reinforced direct lateral incisor bridge was presented as a dependable solution that, in the author’s experience, could likely last approximately 3 to 5 years, giving Rachel the appearance of a natural-looking and normal-functioning tooth. Teeth whitening and direct composite fillings were also presented to Rachel for consideration in order to address the upper left central (tooth No. 9) and 2 lower incisors (teeth Nos. 24 and 25). Rachel was informed that this work could be accomplished in only 2 appointments, within her budget. One appointment would be used for the one-hour in-office whitening procedure, and the other appointment (estimated to take about 2.5 hours) for the new restorations to be completed. Rachel was surprised that she could get everything done so quickly and within her budget. Mostly, she was excited to begin confidently smiling again.

Clinical Protocol
Prior to the chairside fabrication of Rachel’s new smile, a review of the informed consent, clinical timeline, procedure outline, and any final questions from Rachel were addressed. A preliminary vinyl polysiloxane (VPS) alginate substitute (Algin-X [Dentsply Sirona]) impression was taken of the upper and lower arches along with a bite registration (Blu-Mousse [Parkell]). These would be used to create a wax-up of the new lateral incisors, and also for the fabrication of an incisal/lingual putty (Sil-Tech [Ivoclar Vivadent]) matrix to be used chairside during the restorative process.

A schematic diagram of the construction of the everStick C&B (GC America) fiber made up of an interpenetrating polymer network of polymethyl methacrylate and bisphenol A-glycidyl methacrylate.

Two weeks prior to the restorative work to be done, a one-hour, in-office whitening (Zoom [Phillips Oral Healthcare]) procedure was accomplished; in addition, take-home whitening trays were fabricated. The patient was given a 16% carbamide peroxide whitening gel (Pola Night [SDI North America]) so that a baseline whitening shade could be established.

Once satisfied with the whitening results, the restorative procedure was initiated by removing the existing lateral restorations. Pontic areas were created using a soft-tissue diode laser (Picasso Lite [AMD LASERS]) (Figure 3) in order to create a proper gingival contour and to help make the pontic appear as though it were growing out of the gingiva. Intercoronal fiber (everStick C&B [GC America]) (Figure 4) would be used for the reinforcement of the bridge. The everStick C&B fiber differs from others in its construction. Instead of fiberglass fibers, everStick C&B is made up of thin glass fibers surrounded by a proprietary interpenetrating polymer network. This network gives everStick C&B its unique characteristics. The fiber can be used intercoronally or extracoronally, and it is also repairable if debonded or fractured. In addition, when the fiber is reduced or contoured by a bur, no threads or roughness remain, leaving the fiber material completely smooth and strong.

A gingival pontic button was created prior to restoration initiation in order to ensure a smooth interface between the pontic and gingiva. This was accomplished by placing a small mound of flowable composite resin (G-ænial Universal Flo [GC America]) on a Palodent Plus Sectional Matrix (Dentsply Sirona) and light-cured for 20 seconds. Next, this cured mound of flowable composite was removed from the sectional matrix and set aside (Figure 5).
Preparations were then made on the lingual surface of the abutment teeth with a round-ended tapered diamond bur (1847KR-016C [DENTSPLY Midwest]). Occlusion on the abutment teeth should be noted when creating these preparations in order to avoid opposing occlusion interfering with the margin of the prepared teeth (Figure 6). The depth of the preparation should also be deep enough to accommodate the fiber when cured in the preparation, usually 1.5 to 2 mm deep, and should extend into the interproximal area so that the fiber will be invisible from the buccal view when the restoration is complete. Then, after preparation of the adjacent abutment teeth, the fiber should be measured, cut, and prepared for placement.

Figure 17. The final outcome.

The everStick C&B fiber is encased in a silicone package. Prior to removing the fiber, cut the package to the length needed by measuring the approximate length of the fiber with dental floss. To remove the fiber from the silicone, simply remove the paper covering on the silicone closest to the fiber, hold the fiber with a cotton forceps, then pull out (Figure 7). When ready to place the fiber, fill the preparations with flowable composite. Position the fiber into the preparations and press and hold with an instrument. Do not worry if the fiber is longer than needed, as the ends can be trimmed with a bur (Figure 8). Once satisfied with the positioning of the fiber, light-cure for 20 seconds. While positioning the fiber, make sure the fiber is bowed in toward the buccal in the pontic area; this positioning gives the clinician the ability to properly contour both buccal and lingual aspects of the restoration. Once the everStick C&B fiber is cured, cut back the lingual portion of the preps to the lingual contour of the adjacent tooth (Figure 9).

Next, the incisal/lingual putty matrix is tried in to ensure a proper seat.

In order to establish the lingual border, place flowable composite into the lingual of the putty matrix and position the matrix, then light-cure it from the buccal for 20 seconds (Figures 10 to 12). Position the pontic button on the gingiva leaving approximately 1.0 mm of space between the 2 adjacent abutment teeth (Figure 13). Remove the putty matrix and begin building the buccal portion of the restoration starting from the pontic button to the everStick C&B fiber so that everything is held in place. Using a compactable universal high-density composite (G-ænial Sculpt [GC America]) with a layering technique, start with an opaque dentin shade AO1 against the lingual border to mimic natural dentin (Figure 14). On top of these opaque layers, you can put staining or different enamel (translucent) shades to mimic the natural color of the surrounding teeth. In Rachel’s case, A2 was used on the outer enamel surface. A translucent shade was placed in the incisal portion concurrently with the placement of the enamel shade in this buildup to enhance the slight incisal translucency of the natural teeth.

After buildup of the desired shades of composite, shaping of the restoration was accomplished with a pointed carbide finishing bur (379-109 [DENTSPLY Midwest]), a pointed egg-shaped carbide finishing bur (389514 [DENTSPLY Midwest]), and a pointed cone-diamond bur (1859012C [DENTSPLY Midwest]) and finishing discs (Enhance [Dentsply Sirona]). Because of the unique size and consistency of the microfillers in G-ænial Sculpt composite, the finish and polishability of this material is very easy, and it will maintain its luster with daily brushing. In addition to this, excellent handling and wearability also makes G-ænial Sculpt a perfect composite choice for this particular application.

Once completed, Rachel could not get over how the teeth appeared to be a natural part of her smile (Figures 15 to 17). She said, “No more short teeth that catch food underneath! No more hiding my smile and trying not to laugh. Best of all, I feel great about my smile, and more confident!”

The clinician should realize that direct anterior tooth replacement is far from a perfect solution. Often, aesthetics can be compromised due to the amount of space and also depending upon the patient’s occlusion. However, if executed properly with the materials and techniques, these restorations are a reliable, affordable, conservative, aesthetic mid-range solution for patients who are in a holding pattern due to orthodontic care, other dental treatment related reasons, or budget limitations.

Techniques for Predictable Aesthetic Smile Designs

Predictable aesthetics can mean many different things. One definition of predictable is that it is an accurate predetermination of an outcome. As dentists, we can become better at predicting outcomes by understanding risk management.1 Predictable is not the same thing as perfect. Predictable aesthetics does not always translate to perfect outcomes, but rather an end point that lacks surprises. Outside of dentistry, predictable is not always a good thing. For example, when we go to the movies, predictable is bad. For our aesthetic dentistry to not play out like a suspenseful film (with twists, surprises, and scary moments), there are protocols that can be implemented by the clinician to make dental treatments as predictable as possible. In order to finish a case with the outcome being a happy and satisfied patient, expectations must be very well understood from the beginning. One expectation that a clinician may have is that every patient is going to cry tears of joy when they look at their new teeth for the first time in the mirror (Figure 1). While this is not always the case, we can do a better job of controlling the patients’ expectations during treatments. Careful review of pretreatment images from a patient’s photographic series enables the practitioner and the patient to visualize areas of the smile that could use improvement, giving the patient choices for options that minimize risk factors.

When doing aesthetic dentistry, consultations utilizing detailed photographs enable the clinician to emphasize areas of the mouth and smile that will improve significantly with certain courses of action. If patients chose not to undergo those actions to make overall aesthetic improvements, then, at a minimum, they can fully understand where any compromises may exist in the final aesthetics of their smile or in the outlook for the success of the restorations. After reviewing a series of photographs and mounted study models (Figure 2), the clinician should make time to meet with the patient to discuss the steps necessary to get the smile looking as ideal as possible. Taking time to determine the ideal placement of the gingival margins on all patients (high, medium, or low smile-line?) will minimize patient concerns over final results.2 Addressing limiting issues before treatment begins is a better way to add predictability to patient approval at the end of treatment. The patient should be given the opportunity to refuse or pursue treatment to idealize the situation prior to beginning any restorative work. Remember that patient expectations change dramatically when the tooth we treat is in the aesthetic zone versus in the posterior. Often, a patient may be satisfied with an occlusal composite filling that does not match the tooth exactly in the posterior. However, they may be completely unsatisfied with a treatment done to an anterior tooth that may be within the standard of care but falls short from an aesthetic standpoint if it fails to follow the proper principles of smile design.

Diagnosis and Treatment Planning

A 52-year-old female patient presented with a chief complaint of wanting a nicer smile. This is something she had been thinking about for quite some time. The patient was in good overall health and had a history of regular dental visits. Her consultation revealed that she wanted brighter teeth and a more youthful smile. She stated that some cosmetic dentistry had been done more than 10 years ago to help make her upper central incisors look straight before her wedding. The dentist improved her smile using direct composite veneers.

Figure 1. Patients can have unrealistic expectations; doctors can too, thinking that the patient will cry tears of joy when they see their new smile for the first time. Figure 2. Pre-aesthetic visualization should include well-taken digital photos, study models, and a checklist to review before discussing the case with the patient.

A photographic series was taken of the patient at the first appointment in the photo studio. Then, the images were reviewed with her in the consultation room on a large, wall-mounted, flat-screen television. Evaluating the smile with her, while referencing principles of smile design, enabled the clinician and the patient to review all areas of immediate and potential concern (Figure 3). While the aesthetic issues were addressed in the consultation room using the photo series, other risk factors were identified and evaluated using a clinical exam which consisted of radiographs, clinical charting, and a temporomandibular joint exam.

The first step in treatment planning is determining the aesthetic end point, then the clinical exam will help determine the modality for achieving the desired results. Just like understanding what constitutes health when evaluating a patient for occlusal dysfunction, the dentist must understand what constitutes ideal aesthetics in order to provide suggestions for creating a more ideal smile. Treatment planning should start with the goal of making sure the anterior teeth are located in the correct position of the face. This can be accomplished by using incisal edge positions of the maxillary central incisors or maxillary canines with lip at rest.3

Figure 3. (a) Full-face and (b) smile images are a couple of many views used to discuss different aspects of the patient’s smile.
Figure 4. A lip at rest, or repose, is taken to help determine the ideal maxillary incisal edge position. The author utilizes photography and video to analyze the smile. (a) A picture is a static image in time, but (b) a video is more dynamic and can be paused during playback for careful observation.

Both pictures and videos of the patient are used to analyze principles of smile design to assist in finding the most relevant values (Figure 4).4 In evaluating this patient’s full-face-at-repose image, she was informed that the average amount of incisal display with lip at rest is 3.0 to 4.0 mm for a 30- to 40-year-old woman, but that this parameter is quite variable depending on age, lip length, and gender. It was decided that showing slightly more incisal edge was more ideal and in center of the bell curve.

In reviewing her retracted images, discrepancies in tooth proportions of her maxillary anterior teeth were noted (Figure 5). When the previously done aesthetic treatment had been completed to make the central incisors look straight, the width-to-height proportions (W/H) of the centrals had gotten too narrow. This is common when treating cases with crowding. A more ideal W/H proportion of the central incisor is 80%; and the lateral incisor should be about 60% of the width of the central incisor.5 A graphic drawing can relate the ideal proportions based on the width of the teeth from distal of canine to distal of canine. The technique used in digital smile design enables the clinician to determine proportions of anterior teeth when viewed from the front.6 The equation [y = 3.92x] can recreate a graphic drawing in any scenario to assist in finding proportions of central incisors, lateral incisors and canines, where y = (distance from distal of maxillary canine to distal of maxillary canine) and x = (new width of the central incisor) (Figure 6).

In this patient, the central incisors were about a 70% W/H ratio and the laterals were 90% of the width of the central incisors. This relationship creates a violation of a smile design principle that makes the patient appear to have 4 central incisors.7 Restoring or maintaining central dominance in the smile is paramount to aesthetic success.

Figure 5. When viewed from the front, the lateral incisors should be about 60% the width of the central incisors and the canines should be about 60% the width of the lateral incisors. Figure 6. A graphic drawing can relate the ideal proportions based on the width of the teeth, from distal of one canine to the distal of the other canine.
Figure 7. The necessary space would need to be created by directional preparation of the teeth toward the patient’s left side. The gingival zeniths must also be relocated slightly to the patient’s left.

The patient was also informed about the midline, plane of occlusion, incisal plane, buccal corridor, and color of her teeth. She had asymmetric gingival display that was hidden under the lip at full smile. The gingival margins were discussed with the patient and, together, we determined areas that could be improved by soft- or hard-tissue contouring and grafting. A referral was given to her for a periodontist with whom to consult for soft-tissue grafting of tooth No. 6 to make it more symmetrical with the gingival margin height of tooth No. 11. We also discussed some minor tissue contouring of teeth Nos. 9 and 10. The option for orthodontic treatment was also presented as a way to prerestoratively idealize the positions of the teeth. The patient immediately denied tooth-straightening options and also elected not to have the periodontal surgery.

A laboratory wax-up was ordered to represent a prototype of the final restorations. A wax-up serves as a valuable tool to indicate the preparation type and margin placement needed to complete the case. Additionally, communication with the dental laboratory team was facilitated with well-taken photos and videos; these communication tools allow the clinician to play a significant role in designing the case.

Figure 8. (a) A bis-acryl (Venus Temp 2 [Heraeus Kulzer]) mockup was done using a silicone impression matrix of the diagnostic wax-up (Sil-Tech [Ivoclar Vivadent]). (b) The mockup should be an accurate representation of the final product, before depth cuts are made to start the preparations.
Figure 9. In this case, the first set of provisionals lacked the wow factor. The proportions were more ideal and the color was brighter, but the smile could still be improved for the patient by making the teeth whiter, the shapes more accurate, and correcting the facial morphology and incisal canting. Figure 10. Nanohybrid composite (Venus Pearl Bleach Shade [Heraeus Kulzer]) was used as to directly veneer the anterior teeth in a brighter color, changing the shapes and correcting the cant.
Figure 11. (a) The patient returned for a postoperative appointment and digital photo series in the studio. (b and c) The patient was pleased with her new brighter smile and improved teeth proportions.

In order to correct the proportions of the anterior teeth, it was determined that this could not be treated as a conservative preparation smile design. Re­viewing the laboratory wax-up confirmed that the necessary space would need to be created by directional preparation of the teeth toward the patient’s left side (Figure 7). When complex preparation cases present themselves in our offices, the attention to details during the preparation appointment is even more important.

Clinical Protocol
A silicone impression matrix (Sil-Tech [Ivoclar Vivadent]) of the completed diagnostic wax-up was loaded with a bis-acryl provisional material (Venus Temp 2 [Heraeus Kulzer]) and then seated over the patient’s unprepared teeth; this was done after only removing enough enamel (enameloplasty) to properly seat the matrix over the teeth. The resulting bis-acryl overlay closely resembled the finished product of the provisionals and was prepared into using ideal depth cuts for the finished ceramics (Figure 8). When case preparation is more complex and requires direction preparation, the initial mockup may not provide the most ideal final provisional design; this is due to the need for more enameloplasty (or arch realignment) prior to placing the depth cuts. In such cases, the operator suggests doing a second mockup toward the end of the preparation stage of the appointment, prior to making a final impression. The second mockup can then be prepared into for ideal prep design similar to the first mockup. This provides a double check for the ideal reduction needed for cases that have any uncertainty prior to impressioning and provisionalization.

After the teeth were prepared, a final impression was taken using a vinyl polysiloxane impression material (Virtual [Ivoclar Vivadent]) and a preparation bite in silicone bite registration material (Futar D [Kettenbach LP]). Preparation shades were recorded for the laboratory using a preparation shade guide (IPS Natural Die Material Shade Guide [Ivoclar Vivadent]).

Once the records were completed, the provisionals were fabricated using a shrink-to-fit technique. The operator performs this technique as follows: the teeth were isolated (OptraGate [Ivoclar Vivadent]), then the preparations were cleaned with a 2% chlorhexidine gluconate disinfecting solution (Consepsis [Ultradent Products]). (In preparations where the operator breaks contacts, no “spot” etching is necessary to help retain the provisionals.) After the 2% chlorhexidine gluconate was rinsed and the teeth dried, a glutaraldehyde-containing desensitizer was scrubbed onto the teeth (GLUMA Desensitizer [Heraeus Kulzer]) for its desensitizing and bacterial static properties. Next, the desensitizer was suctioned off the tooth and blot dried, rather than blown onto the soft tissues. The preparations were then wet with a primer solution (OptiBond FL Primer [Kerr]). It is the author’s opinion that the primer helps to add some adhesion and adaptability of the bis-acryl to the preparations in the shrink-to-fit technique. The prepared teeth in the matrix were then filled with the correct color of bis-acryl material (Venus Temp 2, bleach shade) and seated over the teeth for 2 minutes. After 2 minutes, the matrix was removed and any bis-acryl flash cleaned away. Any voids were filled with a flowable composite resin (Venus Diamond Flow [Heraeus Kulzer]), light-cured, and the margins trimmed with a Safe End Needle Carbide (H134 ET6 014 [Brasseler USA]). The contact areas were then opened up with a mosquito diamond (8392.31.016, Fine Needle Mosquito Diamond [Brasseler USA]) and checked with floss threaders (Super Floss [Oral-B]) to confirm that the patient could carry out proper hygiene at home.

While the provisional design corrected the proportions of the anterior teeth in this case, there was a lack of wow factor. This was determined to have come from the patient’s desire for a brighter color, slight cant in the incisal plane, as well as some shape improvements that could be made to the existing provisionals (Figure 9). Rather than simply assuring our concerned patient that she would like the lab-fabricated ceramics and sending her home, she was brought back to the office for a contour session to directly add some composite and to contour the provisionals until a result that was more pleasing had been achieved. Nanohybrid composite (Venus Pearl [Heraeus Kulzer]) was added to the provisionals in a direct veneering method. This was performed without the need to etch or place adhesive to the bis-acryl material. We were able to create slightly more volume, brighten the color, and change the shapes (Figure 10). An impression was then taken of the approved provisionals for the laboratory team to follow closely as they created the restorations in all-ceramics.

The pressed lithium disilicate (IPS e.max [Ivoclar Vivadent]) restorations were created in a way to closely resemble the new provisionals, with only slight improvements detailed in the laboratory script. IPS e.max was chosen for its strength, aesthetics, and its optimized translucency. In the posterior, it is routinely chosen by the author due to its flexural strength (360 to 400 MPa) when fabricated as a full-contour monolithic restoration.8

At the cementation appointment, the provisionals were removed, the preparations cleaned, and the all-ceramic restorations were tried in to check the fit and contacts. Next, the aesthetics were evaluated using try-in pastes that resembled the final color of the restorations. Digital photos were taken in the studio before bonding in the restorations to allow the patient to see what the before and after would look like. It should be noted that the patient evaluation part of this process can take up to 45 minutes to ensure that there has been adequate time to see the restorations in the mouth and to address all of the patient’s concerns. The ceramics were bonded in with a light-cure resin cement (Variolink Esthetic LC [Ivoclar Vivadent]) utilizing the tack-and-wave technique. The excess cement was then removed, the occlusion adjusted, and the ceramics polished. In one week, the patient returned for a postoperative visit to address any remaining potential aesthetic concerns, check for any excess cement, finalize the occlusion, and to complete a post-op digital photo series in the studio (Figure 11).

While it is true that the clinician should not expect all patients to cry with happiness upon seeing their new smile in the mirror, we do have the ability to control patient expectations. This is done by first analyzing the principles of smile design with the patient and then thoroughly discussing any areas of limitation that may prevent us from achieving an ideal smile. Although surprises can sometimes be a good thing related to matters outside of dentistry, the patient and the entire dental team benefit from more predictable outcomes.

Service With a Smile

As dentists, we provide services that can transform smiles and lives. We have the ability to solve problems and challenges for our patients that give them the basic ability to smile again, function normally and, best of all, feel good about themselves, both inside and out.

Diagnosis and Treatment Planning

Recently, SueAnne presented for a consultation, motivated by what was glaring at her in the mirror (Figures 1 and 2). At 54 years of age, having lived with veneers that had been placed in stages during the last 20 years, her first stated concern was about the obvious recession that had been slowly taking place. SueAnne then discussed her next issue with great intensity and frustration, using descriptive words like yellow, bulky, and huge. She could see that there was nothing proportional or cosmetic about her existing restorations. She said, on the verge of tears, “I take pride in my appearance and have spent a lot of money on my smile over the years, but my teeth are making me look like I don’t care at all!”

Figure 3. Preparations, left side. Figure 4. Final bite registration (Blu-Mousse [Parkell]).
Figure 5. The completed preparations.

Due to her previous dental experiences, SueAnne also expressed her fear of “pain” and “countless hours” in the dental chair. Also, she was certain this would “take months” to accomplish and wanted a timeline so she could adjust her travel schedule.

Equipped with a full set of digital x-rays, perio­dontal probings, and digital intraoral photos, I was able to “show and tell” SueAnne that she was periodontally healthy and had a stable bite with the exception of some anterior interference. In reviewing the photos with her, confirmation was given that both the color and proportion of her smile could be greatly improved. And, because of the new all-ceramics that we have available today, the bulkiness issue could be addressed as well. During our conversation, SueAnne responded positively to words like longer, leaner, broader, cleaner, and fuller. I could tell that we were on the right track.

SueAnne was informed that we could have everything completed in 2 appointments, within a 2-week time frame. Within those 2 weeks, she would be wearing her prototype smile, which would permit her to evaluate how her new smile could look. If she wanted to change or adjust anything during this phase, she would have the ability to do so. I assured her that this process would be totally painless, and that we would set aside 2 hours for the first appointment and one hour for the second appointment. I reassured her that during these 2 weeks, and immediately after the first appointment, she would be able to eat and drink as she pleased without any restriction. SueAnne calmly asked, “When can we start?”

With the patient in an upright sitting position, a facial plane relator device (Symmetry Facial Plane Relator [CLINICIAN’S CHOICE Dental Products]) was used so the lab team would be able properly mount the case in the correct horizontal and vertical planes for the patient.

After reviewing the informed consent and answering any final questions, a preliminary vinyl polysiloxane (VPS) impression (Silginat [Kettenbach LP]) was taken of the upper and lower arches and sent out with detailed instructions (including smile design) to the dental laboratory team for a diagnostic wax-up, provisional stent fabrication (of the wax-up), a bite stent, and a prep reduction guide.

Clinical Protocol
Upon receipt of the wax-up, preparation of teeth Nos. 4 to 13 was initiated (Figure 3). The previously placed porcelain veneers on teeth Nos. 9 to 13 were removed (1847KR016C [DENTSPLY Midwest] and the preparations were minimally revised. A diode laser (Picasso Lite [AMD LASERS]) was then used to establish a more pleasing soft-tissue architecture. After tooth preparation and the minimal soft-tissue revisions were completed, an initial VPS bite registration (Blu-Mousse [Parkell]) was taken in centric occlusion. Next, the previously placed porcelain veneers on teeth Nos. 4 to 8 were removed and minimally prepared. Again, the diode laser was used to establish a more pleasing soft-tissue architecture. The previous bite was then reinserted and finalized to include the preparations on the right (Figures 4 and 5). After all of the preparations and soft-tissue architecture were evaluated, the bite was evaluated for adequate prep reduction in preparation for the temporaries and eventual restorations. Taper, marginal integrity, and prep design were also taken into account.

With the patient in an upright sitting position, a facial plane relator device (Symmetry Facial Plane Relator [CLINICIAN’S CHOICE Dental Products]) was used so that the lab team would be able properly mount the case in the correct horizontal and vertical planes for the patient. It is critical that one get the vertical component of the Symmetry bite to bisect the face in half and be vertical to the long axis of the face. Front and side view digital photos were then taken of the Symmetry device in place to sharing with the lab team (Figures 6 and 7). Prior to final impressions, the dentin shade was evaluated and noted. A shade of the desired restoration was noted as well. A photograph of all of the selected shades next to the preparations was taken (Figure 8). A shade map of the desired final restoration was also drawn and sent to the lab team.

A final VPS impression was taken only after final evaluation of the margins, tissue, line angle of preparation, and complete field of vision of all of the above. A digital photograph was taken for evaluation as well. The final VPS impression (Aquasil Ultra Xtra [Dentsply Sirona]) was taken using a heavy-body/light-body technique with the patient sitting in an upright position. As the assistant loaded the heavy-body material into an already fitted stock tray, the doctor placed the light body around all of the teeth in the upper arch, covering them completely. It is important to keep the material flowing, maintaining it against the tissues in order to capture less air. Once the tray was filled, the assistant handed the tray to the doctor and then it was inserted into the patient’s mouth, making sure that the lips were worked over the tray. Care was taken when seating the tray so that none of the teeth were touching any part of the tray. A timer was used to follow the setting process to the end, according to the manufacturer’s specifications, and the tray was removed for visual evaluation. Evaluation of the impression under loop magnification should reveal all of the landmarks evaluated in the preparations prior to taking the final impression. It is critical that the clarity of all of the margins, as well as the integrity of the preparation within the final impression, are verified. It is also critical that the clinician identify any voids, bubbles, pulls, or tooth/tray interferences. Any of these issues within the final impression could seriously compromise the final restoration fit and, of course, would require taking another final impression.

Temporization was accomplished with a bis-acryl temporary material (Integrity [Dentsply Sirona]) using the provisional stent that the lab team created from the diagnostic wax-up fabricated prior to doing the tooth preparations. Before placing the material, the teeth were cleaned with a solution containing 2% chlorhexidine (CAVITY CLEANSER 2% Chlorhexidine Digluconate solution [BISCO Dental Products]). Due to the nature and shrinkage of the bis-acryl provisional material around the preparations, a temporary cement is rarely needed. The minimal excess material present after seating the provisionals was removed using hand instruments and then a polishing wheel, disc, and/or cup (Enhance [Dentsply Sirona]). (Note: No high-speed rotary drill instrumentation should be used at this point.) The temporaries were characterized as needed with stain, then a clear unfilled resin glaze (PermaSeal [Ultradent Products]) was painted onto the facial surfaces of the temporaries and light cured (Figures 9 and 10). Finally, instructions were given to our patient along with a Waterpik Cordless Waterflosser (Water Pik). (The author gives all his large cosmetic case patients Waterflossers along with detailed instructions for home care. The author figures this cost into the overall cost of care for the patient.) SueAnne was then given an appointment to return 2 weeks later for the delivery of the final restorations.

When the lithium disilicate (IPS e.max [Ivoclar Vivadent]) final restorations were returned from the lab team, they were inspected for marginal integrity, contact integrity, color, and design prior to try-in. Then, at the seating appointment, the temporaries were removed, and the teeth were cleaned with a solution of hydrogen peroxide and 2% chlorhexidine (CAVITY CLEANSER) and then rinsed. The final restorations were tried in with water only. The parameters noted above were all found to be excellent. The patient was then given a chance to look at the color, shape, and overall look in order to approve the final placement of the restorations.

Once approved, the restorations were removed and cleaned with 37% phosphoric acid gel, then rinsed with water (Figure 11) and thoroughly dried. Next, silane (BIS-SILANE [BISCO Dental Products]) was applied to the internal surfaces of the restorations for 60 seconds then dried with water- and oil-free air. Then the restorations were readied for the resin bonding procedure by placing them in order (Figure 12). Once bonded properly into place using a light-cured resin cement (Calibra Veneer Kit [Dentsply Sirona]), excess cement was removed, and then the bite was checked and adjusted as needed. Digital radiographs were taken to ensure complete seat and to be sure that any excess cement had not been left behind. The final lithium disilicate restorations can be seen in Figures 13 and 14.

SueAnne was ecstatic about her new smile, crying and hugging everyone as she walked out our office door. She continues to refer other patients to our practice and lets us know that, every time she smiles, she is thankful for the care that we provided. With proper training that allows us to expand and perfect our technical skills, the choices in modern dental materials, and excellent communication between the doctor and patient and the doctor and dental laboratory team, our patients’ smiles and lives can be changed forever!
