Impression in fixed prosthesis: fabrication of impression cap

Abstract

The aim of this manuscript was to describe the technique for manufacturing an individual impression cap for tooth preparation impression on the processing of full-contour prosthetic restorations, besides discussing factors and principles involved on this topic. In the present technique, first, a stone partial model is obtained, considering the region to be restored, and then a wax relief is created on its axial region to grant space for the impression material. After applying a resin isolator, the impression cap is obtained by incremental technique using a brush with chemically activated acrylic resin. Finally, a retention portion is created on the top of the obtained cap, the vestibular face is marked and then finishing and polishing are executed.
