The patient case outlined here describes the challenges that prostheses have to meet under high stress. The patient presented to the practice with pronounced abrasion and asked to have his natural dental appearance restored. Full-mouth restorations have their own challenges, and this was particularly so for this patient, who tended to relieve his daytime stress by grinding his teeth at night. After completion of pretreatment and splint therapy, the patient presented to us with the status shown in Figures 1 and 2.

KATANA Zirconia Block (Fig. 1) has hardly any features in common with the zirconia that was so popular in dental laboratories two decades ago and was used as a framework material. In many cases, this innovative zirconia serves as a functionally and aesthetically sensible alternative to high-strength glass-ceramics. Its flexural strength is higher than that of lithium disilicate, its translucency on a level with the low-translucency variant of the ceramic and its surface—if smoothly polished—antagonist-friendly, causing low wear.
