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. BruxZir™ Shaded Milling Blanks are available in four base shades that can be stained to match all 16 shades in Vident's VITA Classical Shade Guide range.
FABRICATION PROCESS: The case was scanned on the 3Shape D700 and milled with the BruxZir™ Milling System using a BruxZir™ Shaded Milling Blank 200 to achieve the base shade of A2. The pre-shaded blocks were sintered and finished using simple staining and glazing techniques.
Vuong was given multiple digital photos showing various shade tabs adjacent to the teeth; the challenge was to match the highly characterized adjacent natural tooth with staining. She used pink and violet BruxZir™ Coloring Liquid to tone down the value, and then used white to mimic the decalcification on the adjacent tooth. The final BruxZir® Shaded crown was cemented using Ceramir® Crown & Bridge luting cement.
