Method for developing an optimal emergence profile using heat-polymerized provisional restorations for single-tooth implant-supported restorations.
This article describes a method for creating an improved emergence profile with single-tooth, implant-supported restorations. An easily trimmed silicone gingival substitute is used to allow polymerization of acrylic resin provisional restorations to achieve control of the emergence profile. Gingival trauma is minimized by eliminating intraoral use of monomer and minimizing surgical procedures. Provisional restorations can be assessed to ensure the contour is acceptable and the trimmed gingival substitute can be used to fabricate a similar profile in the definitive prosthesis. The provisional restorations may be used instead of standard prefabricated healing abutments to guide the healing contours of the peri-implant gingival tissue.
