Abstract
Abstract
Implant assisted removable partial denture (IARPD) combined with implant surveyed prosthesis has been proposed as a treatment alternative to conventional removable partial denture when additional retention, support and stability are needed in partially edentulous patients. However, a few studies have investigated the implant surveyed crowns applied to IARPDs. This retrospective study was conducted to evaluate implants applied to IARPDs as surveyed crowns clinically and radiographically. This study was performed on patients who treated with IARPD combined with implant surveyed prosthesis from 2015 to 2021. A total of 74 implants applied to 27 IARPDs were evaluated. The factors such as implant location, Kennedy classification, and type of opposite dentition which possibly affected the prognosis of the implants were recorded. The survival rate of the implant and marginal bone resorption around the implant were investigated. The cumulative survival rate of implants applied to IARPD as abutments was 97.30%. The implant survival rates in the maxilla and mandible were 90.47% and 100% respectively and there was a significant difference (p = 0.044). In marginal bone resorption, there was no significant difference for each condition. Properly planned IARPD combined with implant surveyed prosthesis would be an alternative treatment option for partially edentulous patients.
