The urethanes, PVC, acrylic resins, and silicones are still the most popular among a large number of materials being used to fabricate facial prostheses. Each material has advantages and disadvantages. The ideal material is not yet available. It was found that Silastic medical adhesive type A, a preparation of methyl triacetoxy silane crosslinked silicone, possesses a wide range of biologic, clinical, and technical advantages over other materials. However, the poor adheophilic properties of this material remain its most significant disadvantage. A processing technique for methyl triacetoxy silane crosslinked silicone is presented. Further investigations are being conducted to improve this material.
