Retrospective 2‐ to 7‐Year Follow‐Up Study of 20 Double Full‐Arch Implant‐Supported Monolithic Zirconia Fixed Prostheses: Measurements and Recommendations for Optimal Design

Abstract

The results of this study indicated that full-arch MZ-FPs without cutback, or with partial digital cutback and veneering ceramic, were a therapeutic option. Recommendations regarding the thickness of zirconia at the level of the distal screw access openings, the crown height spaces, and the lengths of the cantilever segments were recorded. Additional in vitro and clinical studies will be required for more scientific analysis of the criteria for design of this type of prosthesis to minimize prosthetic complications. Long-term and multicenter studies are needed to corroborate the findings discussed in this report.
