A systematic review of the survival and complication rates of implant‐supported fixed dental prostheses (FDP s) after a mean observation period of at least 5 years

Survival of implants supporting FDPs of 95.6% after 5 years and 93.1% after 10 years. When machined surface implants were excluded from the analysis and only rough surface implants included, the survival rate increased to 97.2% after 5 years.

The survival rate of implant-supported FDPs was 95.4% after 5 years and 80.1% after 10 years of function.

The survival rate of metal–ceramic implant-supported FDPs was 96.4% after 5 years and 93.9% after 10 years.

Only 66.4% of the patients were free of any complications after 5 years.

The most frequent complications over the 5-year observation period were

Fractures of the veneering material (13.5%)
Peri-implantitis and soft tissue complications (8.5%)
Loss of access hole restoration (5.4%)
Abutment or screw loosening (5.3%)
Loss of retention of cemented FDPs (4.7%).
