Technical report demonstrates a streamlined relining workflow for provisional restorations on feather-edge abutments, suggesting improved chairside efficiency and biocompatibility.
This article describes a simplified technique for relining provisional prostheses on natural abutments that can be applied to this specific type of tooth preparation with feather-edge finish line. Starting from a diagnostic wax-up, a provisional fixed restoration is constructed, containing all the correct structural information. This includes the controlled depth of the prosthetic margin into the gingival sulcus, the emergence profile, and the area from the emergence profile to the gingival third. Chair time is saved during the clinical procedures because the finishing and polishing steps are shortened, and the resulting provisional restoration is precise and highly biocompatible. This technique allows for a simple and quick relining and finishing procedure and for the delivery of an esthetic and biocompatible provisional restoration.
