The Aesthetic Contour Graft - Enhancing peri-implant soft tissue contours and pontic sites with guided bone regeneration

Abstract

Objective: In this article, we will discuss strategies for enhancing peri-implant soft tissue contours and pontic sites with hard tissue augmentation. Clinical consideration: One of the keys to the esthetic illusion of an implant-supported restoration is to create an ideal emergence profile. A critical part of any emergence profile is based on the height and thickness of the tissue surrounding the restoration and whether there are any defects in this tissue. Even when there is adequate bone in which to place implants, if any irregular ridge anatomy that supports this tissue is not corrected, then an unesthetic appearance of the restoration can result due to the lack of soft tissue with which to develop a proper emergence profile. Conclusion: Most peri-implant soft tissue deficiencies represent an underlying bony defect that can be corrected or enhanced through bone augmentation. Clinical significance: Traditional methods of enhancing soft tissue emergence profiles around implants and pontic sites mostly involve the use of soft tissue augmentation techniques. Although there are few reports of the use of bone augmentation for this purpose, soft tissue contours can be enhanced by augmenting the underlying bone contours and, in many instances, may obviate the need for subsequent soft tissue augmentation.
