Transitional Custom Abutments
Optimizing Aesthetic Treatment in Implant-Supported Restorations
Ernesto A. Lee, DMD
As the discipline of implant prosthodontics continues to evolve, additional emphasis has been focused on the role of adequate emergence profiles and peri-implant soft tissue contours. Despite the development of anatomically shaped healing abutments, currently advocated techniques exhibit clinical limitations. This video introduces the transitional custom abutment technique as a method of manipulating the supraimplant soft tissue contours so that optimal emergence profiles and increased restorative flexibility can be achieved in the treatment of patients with compromised fixture angulation.
