Abstract

The treatment methods of the partial edentulous patients are fixed partial denture, removable partial denture and implant supported fixed partial denture. Many physicians select implant fixed partial denture in a lot of partial edentulous cases base on its stable success rate. However this method cannot apply to all cases because of various reasons. so the removable partial denture is still used method. But removable partial denture has the rotation problem because of supporting ability difference between tissue and tooth. This problem causes malfunction and uncomfortable denture. Moreover, there are opinions that removable partial denture indicate continuous alvelolar bone resorption. Removable partial denture cannot apply in patients who have severe gag reflex. To solve these problems, several dentists attempted additional implantations on partial edentulous area and overdenture designs. Additional implantations have increased retention and stability of denture and produced successful results. Using implant to overcome problem of complete denture is more common than removable patiral denture. According to the 2002 McGill Consensus, recommendation about a full edentulous patient was the implant retained overdenture using two implants on the mandible. This clinical report describes the treatment of a patient with these prosthetic solutions
