Randomized Clinical Trial of Implant‐Supported Ceramic–Ceramic and Metal–Ceramic Fixed Dental Prostheses: Preliminary Results

Abstract

Although there were no significant associations between connector height, curvature of gingival embrasure, core/veneer thickness ratio, and material system and the survival probability of implant-supported FDPs with zirconia as a core material, the small number of fractures precludes a definitive conclusion on the dominant controlling factor.
