Purpose To retrospectively assess complications and clinical and radiographic outcomes of edentulous patients treated with double full‐arch implant‐supported fixed complete dental prostheses (IFCDPs) after a mean observation period of 5.1 years. Materials and Methods The single‐visit clinical and radiographic examination included medical and dental history review and clinical assessment of biologic and technical complications encountered with all implants and IFCDPs. Life table analysis and Kaplan‐Meier survival curves were calculated. Analysis was conducted to evaluate the association between prosthesis survival and several risk factors such as type of opposing occlusion, nightguard use, and presence of bruxism. Results Nineteen edentulous patients restored with 38 IFCDPs were included. A total of 249 implants were placed and 2 implants failed after a mean observation period of 5.1 years (range: 1‐12 years), yielding an overall implant survival rate of 99.2% and prosthesis survival rate of 92.1%. Three out of 38 IFCDPs were lost, 1 after implant losses and 2 due to technical complications. The most frequent minor biologic complication was soft tissue recession with an estimated 5‐year rate of 45.5% (95% CI: 39.4‐57.5), while the most frequent major complication was peri‐implantitis with an estimated 5‐year implant‐based rate of 9.5% (95% CI: 6.7‐11.3). The most frequent minor technical complication was wear of the prosthetic material with an estimated 5‐year rate of 49.0% (95% CI: 37.4‐76.4), while the most frequent major technical complication was fracture of the prosthetic material with an estimated 5‐year dental unit‐based rate of 8.0% (95% CI: 6.6‐10.1). Conclusions After a mean use time of 5.1 years, high implant and prosthesis survival rates were observed. The most frequent major biologic complication was peri‐implantitis, and the most frequent major technical complication was fracture of the prosthetic material. The 5‐year estimated cumulative rates for “prosthesis free of biologic complications” was 50.7% (95% CI: 33.7‐65.4) and for “prosthesis free of technical complications” was 57.1% (95% CI: 39.3‐71.5).
