Abstract

ABSTRACT
Mechanical complications may have a significant impact on the outcome of implantsupported restorations; however, few studies address the topic. This study investigated
the outcomes of implant supported restorations with mechanical complications. A total
of 378 patients with 378 restorations supported by 1283 implants were included. Results
demonstrated a prosthetic and implant cumulative survival rate at 5 years of 99.7% and
95.7%, respectively. Maxillary implants were a determinant for implant failure (hazard
ratio= 6.7), while a reduced risk was registered for single tooth restorations (hazard ratio= 0.1) after adjusting for other variables of interest.
