Yang, Kim, and Kim: Eight-year follow-up of two different removable prostheses using six implants in maxillary edentulous patients


An implant-supported fixed dental prosthesis (ISFDP) or an implant-supported overdenture (IOD) are good options when treating a completely edentulous jaw opposing natural teeth. However, an ISFDP for a full arch requires sufficient bone quality and quantity, which limits its application. Meanwhile, using an ISFDP as an abutment of a removable partial denture has been considered recently. This clinical report discusses the treatments applied to two patients with edentulous maxillas and opposing natural teeth: one was treated with an IOD and the other was treated with an ISFDP and removable partial denture. Follow-up and management were performed for 8 years.
