Influencing factors and esthetic considerations of emergence profile of implant dentures in the anterior teeth area

Abstract

The emergence profile of implant restorations plays an important role on the final esthetic outcome. This article intends to review the emergence profile design of implant restorations in the anterior teeth area, and analyse the factors that affect the emergence profile of implant restorations: implant neck design (non-platform-switching bone level implants, platform-switching implants, and soft tissue level implants), implant position and inclination (implant depth, buccal-lingual position, mesiodistal position, and axial inclination), the type of the abutment, quality and quantity of peri-implants soft tissues. The article aims to provide clinical guidelines for the emergence profile design of implant prostheses based on existing literatures and clinical experiences.
