Introduction : For patients with Kennedy Class I and II partially edentulous alveolar ridges, implant-supported prosthetic appliances (ISPAs) can achieve denture stability and help recover the masticatory function of patients better than conven tional removable partial dentures. In this paper, we report the clinical results for eleven patients with Kennedy Class I and II partially edentulous ridges treated with ISPAs, and also review the literature.
Case description : Eleven patients were treated with ISPAs. Their mean age was 64.5 years. The patients consisted of nine females and two males ; three were treated in the mandible and eight in the maxilla. The number of missing teeth ranged from 8 to 11. Thirty-three implants were placed in the 11 cases, and five types of attachment system were used (magnets : 3 cases, locator attachments : 2 cases, milled healing abutments : 2 cases, bar and clip attachments : 2 cases, and extra-crown attachments : 2 cases). Follow-up periods ranged from 41 to 183 months (mean 97 months). There were no failed implants and therefore the implant survival and prosthesis survival rates were 100％ for the 97-month mean observation period. Three cases had no prosthetic complications. Eight cases had problems, such as fracture of denture bases, wear of artificial teeth, and removal of magnets, and only two abutment teeth were extracted. However, both prosthetic complications could be re paired.
Conclusion : The results of this study suggested that ISPAs therapy is a predictable and minimally invasive treatment method for patients with multiple tooth loss.
