Background:
The use of impression copings to make the final impression results in a master cast in which the soft tissue configuration around the implant platform is circular. Therefore, any soft tissue sculpting developed clinically by the provisional restoration is squandered.
Purpose:
The purpose of this report was to present a method for the precise transfer of the peri-implant soft-tissue developed by a customized provisional restoration to an emergence profile cast.
Materials And Methods:
The emergence profile cast is obtained from an impression of the implant-supported provisional restoration and poured with a soft tissue model material. It is used for the fabrication of the emergence profile of the implant abutment and the cervical section of the crown.
Conclusion:
The technique described is simple, accurate, predictable, and does not require additional chair time for the customization of the impression coping or the fabrication of a new provisional restoration.
Clinical Significance:
This article describes a technique that results in an implant restoration that mimics accurately in its emergence profile that of the carefully crafted and customized provisional restoration. The reproduction of the soft tissue contour from the provisional to the final restoration results in an improved esthetic outcome of the final restoration.
