Implant-Supported Fixed Complete Prostheses: Survival and Complications

Phillip Bonner, DDS


A study published in Clinical Oral Implants Research assessed the rate of biologic complications and implant survival in edentulous patients treated with implant‐supported fixed complete dental prostheses (IFCDPs) after a mean observation period of 5.2 years (range: 1 to 12 years).

Single-visit clinical and radiographic examination was performed to assess types and rates of biologic complications with ceramic IFCDPs (Group 1) and metal‐resin IFCDPs (Group 2).

The study found that of 457 rough surface dental implants supporting 71 IFCDPs (52 patients), 6 had failed, yielding an implant survival rate of 98.7% after a mean observation period of 5.2 years after definitive prosthesis insertion. The 6 implant failures in 3 patients occurred after 5 years and affected the prosthesis survival.

Soft tissue recession was the most frequent minor biologic complication, whereas peri‐implantitis was the most frequent major biologic complication. A 10‐year implant‐based mucosal recession rate of 77% (7.7% annual rate) and a 10‐year implant‐based peri‐implantitis rate of 20% (2% annual rate) were found.
