Prosthetic Rehabilitation of a Patient with an Orbital Defect: A Simplified Approach

Abstract

Large oro-facial defects consequences in serious functional as well as cosmetic deformities. Acceptable cosmetic results usually can be obtained with a facial prosthesis. This article describes prosthetic rehabilitation of a 35year-old female having a left orbital defect with HTV silicone material. A modified technique to fabricate an acrylic substructure in heat-polymerizing polymethyl-methacrylate to support silicone facial prosthesis was illustrated. The resultant facial prosthesis was structurally durable and esthetically acceptable with satisfactory retention. This technique is advantageous as there is no need to fabricate the whole prosthesis again in case of damage of the silicone layer because the outer silicone layer can be removed and repacked on the substructure if the gypsum-mold is preserved.
