RESTORATIVE PROBLEM: The patient had a full cast crown on tooth #30 but wanted a more esthetic appearance.
TREATMENT PLAN: The dental team opted for a full contour zirconia restoration using the new Katana Zirconia ML, a gradational multilayered zirconia disc with four layers of color--35% enamel, 15% of the first gradation layer, 15% of the second gradation layer and 35% dentin--that offers the look of layered porcelain.
The pre-colored multilayered shades...

RESTORATIVE PROBLEM: A 36-year-old patient presented with a request to have teeth #30 and #31 restored as recommended by his general dentist. These molars had existing large pin-retained amalgam buildups that were starting to show signs of occlusal wear.
TREAMENT PLAN: Dr. Sy-Munoz prescribed monolithic crowns made from Zenostar full contour zirconia because of its strong physical properties, pleasing esthetics and optimal biocompatibility.
DENTAL TEAM: Sven Jesse, Jesse & Frichtel Dental Labs and Dr. Edward Narcisi, DMD, both of Pittsburgh, PA
RESTORATIVE PROBLEM: The patient—the wife of one of the laboratory owners--had an existing all-ceramic restoration on tooth #30 that cracked (she had previously had a PFM crown that also chipped).
TREATMENT PLAN: Since functionality and esthetics were a priority, a Zirlux FC2 full contour zirconia crown was chosen. The laboratory prefers to use Zirlux FC2 because of its flexural strength and low wear against opposing dentition. The Zirlux FC2 system consists of five pre-shaded...

RESTORATIVE PROBLEM: The patient was missing a second bicuspid (#12), didn't want an implant crown and was also concerned about the reduction of the adjacent healthy teeth.
TREATMENT PLAN: To address the patient's desire for the most minimally invasive solution, the team opted for a full contour bridge with minimal retention, using ORIGIN LIVE Plus zirconia since the case required both high strength (for minimal enamel removal) and high translucency (for full contour). Dr. Barker...

RESTORATIVE PROBLEM: A 62-year-old female presented with implants on teeth #3, #4 and #5 and a PFM bridge placed by another dentist. The implants had been placed too far buccally and the patient was unhappy with the esthetics and thickness of the bridge. The patient's occlusal planes were also uneven, and she had another large-span anterior bridge on teeth #6 through #11 that was starting to show signs of decay at the margins.
TREATMENT PLAN: The team opted to remove both bridges and the remaining...

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...

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....
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: 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,...

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...
