A flexible moulage for the fabrication of an orbital prosthesis

A technique is disucssed by which a flexible three-piece moulage may be fabricated. This procedure is a useful aid in the modeling of an orbital prosthesis. It permits the continued transfer of a wax pattern from the moulage to the patient utilizing the tissue undercuts for the retention and stabilization of the pattern. The critical task of properly positioning the ocular prosthesis is simplified by the increased stability of the entire pattern. This is of the utmost importance since even a slight error in the alignment of the eye can entirely negate the effect of an otherwise accurate prosthesis. In addition, the retention of the wax pattern simplifies the carving procedure, and accurate detail is easily secured. The acrylic resin surface on which the final silicone prosthesis is cured has proven to be accurate. Well-adapted, thin margins of the facial prosthesis have been consistently obtained.
