Mixed Use of 3 Different System Implants for a Fixed Detachable Prosthesis in the Resorbed Edentulous Maxilla：Report of a Case

Abstract

It is frequently difficult to treat a resorbed edentulous maxilla with a conventional removable prosthesis, and then an application of dental implant is required. We reported a case of a 52-year-old man with a chief complaint of a poorly fitting maxillary full denture where previous dentists tried to restore the case using the fixed implant bridge with 8 ITI and 5 IMZ implants. He had experienced failures of implant treatments two times, but he requested an implant bridge again. We restored his maxilla with an implant-supported fixed detachable prosthesis using 4 Brånemark implants, and also supplementally the remaining other system implants, one ITI and two IMZ implants, previously placed by his dentists.
