Emergence profile considerations of implant abutments.

Osseointegration of oral implants is well recognized and accepted, and the procedures governing fixed prostheses, occlusion, and aesthetics have also been sufficiently described. One major point for achieving optimal results still warrants further discussion and lies in the fabrication and management of the transgingival junction elements between the neck of the implants, the prostheses, and the surrounding periodontal tissues. The objective of this article is to review the transgingival junction elements for the practitioner with recommendations for achieving optimal clinical results. Three cases are used for illustration.
