Impact of Material and Design on the Mechanical Behavior of Implant-Supported Hybrid Fixed Prostheses

Despite the favorable long-term outcomes reported with implants-prosthetic rehabilitations, biological and technical complications may be frequent. This review aimed to describe the different implant-supported hybrid prostheses, assessing the frameworks designs, materials, mechanical behavior, and prosthetic complications. A search was done using Medline/PubMed and Scopus databases from January 1985 to December 2022. The most relevant papers were selected for the review from the retrieved papers. Manual search for list of references was also added. Mechanical complications are not unique to metal-acrylic resin HPs and have been documented with other metal-based implant-supported reconstructions and zirconia frameworks. Prosthetic complications including ceramic veneer chipping and framework failures have been reported with ceramic veneered zirconia complete arch frameworks. The design, fabrication method, material and misfit of implant-supported frameworks significantly influence the rate of prosthetic complications associated with full-arch HPs.
