Abstract: Compared with the complete denture，edentulous implant restoration can improve the retention and stability of denture and improve masticatory efficiency and life quality，which has become an ideal treatment for edentulous patients. The concept of implant restoration in edentulous patients has changed from recovery of function only to recovery of both function and aesthetics. How to achieve expected aesthetic effect involves all the process，including aesthetic analysis，designing the implant planning and treatment. This article expounds the common aesthetic defects，design of implant restoration and common mistakes in the treatment of edentulous patients in order to provide some reference for clinicians in the edentulous implant restoration.
