Técnicas de moldagem da máscara facial

Abstract

INTRODUCTION: There are described in the literature several techniques for shaping the face mask in order to develop models for fabrication of maxillofacial prostheses. OBJECTIVE: This article aims to describe two techniques used for facial moulage, the conventional technique and conventional technique with modification, highlighting their advantages and disadvantages. CASE REPORT: In the first technique, the impression material is deposited over the region of interest and then a reinforcement layer of plaster type II is putting to cover the impression material. The modification of the conventional technique begins with a relief with cotton over the facial tissue, applying a layer of plaster type II in order to construct the reinforcement layer and, after its crystallization, the application of impression material over the area to be molded, followed by its plaster mask contention. CONCLUSION: The choice of impression technique and materials used will depend on the ability of the professional. The important thing is to make a moulage in order to get an accurate facial cast for the prosthesis' success.
