Practice-Based Evidence from 29-Year Outcome Analysis of Management of the Edentulous Jaw Using Osseointegrated Dental Implants
Abstrakt
The aim of this multi part retrospective study was to discuss the value of managing the treatment of edentulism as a "chronic condition" and to provide a practice based evidence example of the anticipated and unanticipated treatment outcomes edentulous patients treated with implant retained prosthesis with the original Braanemark protocol at the Mayo Clinic from 1983 to 1991. 264 patients with at least one edentulous jaw were rehabilitated with an implant retained prosthesis from 1983 to 1991. Anticipated and unanticipated prosthetic and biologic events were recorded.
The mean duration of follow up was 13.0 years. At least one prosthetic event was experienced by 148 (58%).
Individuals eighty-one (32%) experienced at least one biologic event. Overall survival rates at 20 years were: prosthesis - 86%, survival free of implant failure - 92%.
