임프란트 지지 국소의치의 임상적 연구

Abstract

OBJECTIVE The purpose of clinical study was to evaluate the survival of dental implants used in restoring patients with implant supported removable partial dentures (ISRPDs) of different configurations. MATERIALS AND METHODS The sample consisted of 20 consecutively treated partially edentulous patients, who, between 2003 and 2008, had a total of 84 implants placed in different arch sites and who were treated with ISRPDs. The mean age was 57 years. Mean follow up time from delivery of ISRPDs was 3 years 2 months (range, 1 to 6 years). Osseointegration failure, postoperative complication of dental prosthesis, and the success rate of ISRPDs were retrospectively evaluated using clinical and radiographic examination. RESULT The overall implant survival rate was 100%. During follow up, the one clasp of removable partial denture was broken in 1 year 11 months after prosthesis delivery. All patients were satisfied with their prosthesis. CONCLUSIONS Implant supported removable partial dentures could serve as favorable prognosis. Careful patient selection, with an appropriate maintenance and recall system, is recommended to obtain satisfactory results.
