Subperiosteal Implants in Treatment of Total and Partial Edentulism - A Long Term Follow Up

In 73 cases with advanced alveolar bone loss we placed 93 subperiosteal implants. The implants were observed for 5 to 17 years after placement. The mean period of observation was 7, 63 years. The mean survival rate of the implants for the entire observation period is 74.7 %. The survival rate of the subperiosteal implants for a 5-year observation period is 94.5 % and the complication rate is 22.2 %. The survival rate of the subperiosteal implants for the entire period of observation (5-17 years) is 96 %.
