title: Influence of the implant position on the aesthetics of the restoration.
abstract: Well-placed implants are a prerequisite to achieving functional as well as aesthetically successful implant-supported restorations. In addition to sufficient bone volume, a precise emergence profile is an important factor in obtaining the optimal result of the final restoration, presenting a natural gingival silhouette. Restorations with a ridge lap design are no longer acceptable. The learning objective of this article is to review implant placement with emphasis on the factors that influence implant position and angulation. Anatomic discrepancies between the natural tooth root and the implant are discussed in context of treatment planning, including the position and direction of the implants, determined by the anticipated prosthetic restorations. The sagittal plane of implant position is reviewed versus horizontal or vertical placement in the anterior as well as posterior region. Function, comfort, access for hygiene, and aesthetics are the four essential requirements for an implant-supported restoration.
