With today’s focus on highly cosmetic restorations and appliances, patients want functional, natural-looking removable partial dentures. Proper material selection is a key part of ensuring patient satisfaction.
Rejuvenation dentistry is an approach based on a model of health that considers not only a patient’s teeth but the entire masticatory system, including jaw joints, nerves and head and neck muscles, and maintains that problems occur when these components aren’t working in biological harmony.

Step ToothMaster Bay, CDT, DTG, discusses his technique for restoring the six anterior teeth for a patient who wanted to replace discolored anterior teeth with crowns that matched her natural A1 shade.
By Renato Carretti
A female patient, approximately 65 years old, presented with tooth #10 fractured down to the root; it was extracted and an implant was seated. She had had a gold filling on tooth #9 for nearly 45 years, and couldn’t imagine her appearance without it.
Although the gap following implantation was not provisionally restored, the gingival situation was excellent (see Figure 1). During the intraoral try-in, the crown showed good results in the cervical gingiva as well as good fit and shade match.
Optimizing the Surface
It’s not possible to recreate the surface of a crown to mimic a natural tooth by means of a glaze firing alone. Consequently, the glaze firing was followed by manual polishing with pumice powder and a hand brush, resulting in a matte glaze (see Figure 2). This takes five to 10 minutes but with a little experience, the surface looks considerably more natural than with a glaze firing: the finer the structure of the ceramic—in this case, VM 13—the...

An approximately 50-year old patient presented with a fracture on tooth #9 (see Figure 1). Since the root was also fractured, the tooth was extracted and a clasp-retained provisional restoration was seated (see Figure 2).
The gingival papilla was prepared prior to placing the implant in order to ensure subsequent seamless progress of the case. After placing the implant, sufficient time was left for the gingiva to regenerate, which was in perfect condition after healing (see Figure 3).
The challenging aspect of this case was to match the transparency of tooth #8. During the first firing, the basis for the transparent appearance was created with VM 13 Base Dentine layering, first with a 1:1 mixture and then with a 1:2 mixture of Base Dentine and Neutral NT. To achieve a shade close to that of tooth #8, Interno shades were applied before the second firing, and fixed with intermediate firings.
Next, neutral powder in its pure state was applied, followed...

A patient who was approximately 45 years old presented with a devitalized tooth #10 with dark discolorations (see Figure 1). This was a classic case for a metal-ceramic restoration because the discolored tooth stump would show through an all-ceramic restoration and make the crown look grey.
With this VM 13 crown, the goal was to reproduce numerous small enamel cracks, mamelons and decalcification marks like those of the adjacent tooth #9 (see Figure 2). After the first firing, Interno 1 (white smoke) was inlaid for the small enamel cracks; Interno 2 (sand) was used to emphasize the mamelons. Akzent 17 (Niagara) was applied to emphasize the bluish glaze at the incisal edges; a glaze firing was performed.
A dark shadow below the gingiva was visible in the provisional restoration (see Figure 3) and still remained after seating the crown (see Figure 4). In this particular case, this unavoidable situation was probably due to the dark interior of the crown being reflected in...

Laboratory Owner Michael Suris has recently started using Strategy Milling©’s services to mill full contour gold crowns and bridges for Dental Professional Labs, Inc. in Merrillville, IN. He offers a step-by-step look at fabricating a milled gold posterior crown.
After watching technicians drop one too many crowns and losing productivity, Ceramist Tom Greggs invented Stabiliner, which reduces the risk of slippage of milled restorations during contouring/finishing procedures.

Jean Chiha, CDT, shares his step-by-step process for fabricating a posterior, three-unit, implant-supported bridge using Noritake KATANA Multi-Layered (ML) Zirconia.
The challenging aspect of this case was that one of the implants was improperly placed between #7 and #8. Steve Lee explains how he made a screw-retained zirconia framework with pink gingiva tissue to recreate the lost gingiva and then cemented on four single crowns made from IPS e.max to the framework.
