Int J Periodontics Restorative Dent 35 (2015), No. 3 28. Apr. 2015
The aim of this study was to evaluate the performance of monolithic zirconia in function and minimally veneered zirconia (feldspathic ceramic, not in function, on the facial surface to enhance tooth esthetics or replace gingival structures) on both teeth and implants. This open-ended consecutive case series involved 238 patients between the ages of 16 and 92 years, 1,022 restoration units, and 365 cases in all categories of tooth and implant restorations in a private practice clinical environment for up to 68 months. The restoration parameters monitored in the patient base were fracture, cracking, or chipping of the zirconia structure and/or the minimally veneered feldspathic ceramic. There were no observed complications with respect to these parameters associated with any of the restorations included in this study.
