Objective To systematically assess survival, failure, and complication rates of all-ceramic implant-supported monolithic and micro-veneered FDPs (i-FDPs) in partially/completely edentulous patients compared to veneered restorations.Materials And Methods An electronic search identified prospective clinical studies on all-ceramic i-FDPs with at least one inter-implant pontic and a minimal follow-up of 1 year, with no restrictions in language and publication date.Results Only studies on posterior 3-4-unit and full-arch i-FDPs were identified. Twelve studies assessing monolithic, fully veneered, and micro-veneered restorations were included. Regardless of veneering design, the meta-analysis indicated a 3-year success rate of 89.36% for 3-4-unit and 75.56% for full-arch i-FDPs, and an estimated 3-year survival rate of 98.64% and 96.45%, respectively. Analyzing veneering design influence was feasible only for 3-4-unit i-FDPs. Monolithic and micro-veneered 3-4-unit restorations showed significantly lower chipping incidence than fully veneered ones (p 1000 MPa). No conclusions can be drawn for multilayer zirconia or other ceramics.
