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.

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...January 13 at 11:06 am in How to Use VITA VM 13 for Challenging Anterior Metal-Ceramic Restorations
By Renato Carretti
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...January 13 at 10:56 am in How to Use VITA VM 13 for Challenging Anterior Metal-Ceramic Restorations

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.

How to Match Central Incisors Using a Jacket Crown and Laminate Veneer Made With Noritake EX-3 Porcelain
Mismatched central incisors are a relatively common scenario, and a source of distress to the patient. Despite the high occurrence of these cases, it remains technically challenging for the technician and dentist alike to restore two central incisors that are esthetically balanced while being true to form and function. In addition, the complexity of the case is magnified by the fact that very often, each incisor requires different treatment.

DENTAL TEAM: Scott Atkin, Creative Dental Laboratory and Dr. Michael Foley, both in Scottsdale, AZ
RESTORATIVE PROBLEM: A 79-year-old male patient with an existing PFM full mouth rehab needed a classic A3 shade replacement bridge for teeth #11 through #15.
TREATMENT PLAN: A five-unit Crystal Diamond full contour bridge was prescribed. Crystal Diamond was chosen for its excellent translucency and strength, ideal for highly esthetic anterior and posterior metal-free restorations.
FABRICATION PROCESS: The case was scanned using a 3Shape D710 scanner and milled using Delcam software on a DentMill...
DENTAL TEAM: Ken Upright, Oxford Crown & Bridge, LLC and Dr. Shelley Olson, DDS, FICD, Granville Family Dentistry, both in Oxford, NC
RESTORATIVE PROBLEM: A female patient fractured the entire facial surface and buccal cusp of tooth #4, which had an old MOD amalgam restoration. Due to a 2mm diastema, the entire mesial aspect of the crown would be exposed in the patient's smile, so shade quality was a foremost concern.
TREATMENT PLAN: Because of her positive experiences with the material, Dr. Olson prescribed a Delta Zirconia full contour crown to restore tooth #4. High Translucent Delta Zirconia,...
DENTAL TEAM: Gyu Cho, CDT, 3D BioCAD Milling Center, Renton, WA and Dr. Ronald Bryant, Seattle
RESTORATIVE PROBLEM: The patient presented with severe occlusal wear on his natural teeth; the lower anterior teeth were also very crooked and discolored. The existing crowns also exhibited wear, tissue retraction, dark margins and uneven shades from one crown to the next. Teeth #5, #12 and #14 were missing, requiring implants.
TREATMENT PLAN: A full-mouth restoration with 28 units was proposed and had full compliance from the patient. The team opted to use gold-hue abutments to provide a very natural,...
DENTAL TEAM: Cindy Vuong and Dr. Michael DiTolla, both of Glidewell Laboratories, Newport Beach, CA
RESTORATIVE PROBLEM: The patient presented with a pre-existing discolored PFM restoration on tooth #8.
TREATMENT PLAN: Dr. DiTolla prescribed a full contour BruxZir® crown, and decided to take the opportunity to test the translucency of Glidewell Laboratories' new BruxZir™ Shaded material, which offers complete color penetration all the way through the restoration for greater shade consistency. The new material also prevents shade changes or white "show-through" after occlusal adjustment....

RESTORATIVE PROBLEM: A young female patient lost teeth #7 through #14 in a car accident and was already wearing a provisional restoration that had resulted in pronounced jawbone atrophy.
TREATMENT PLAN: The team opted for a fixed superstructure supported by six implants at sites #7 and #8 and #11 through #14. Due to inadequate bone structure, the restoration would be an occlusally...
