Application of Segmented Polyurethane Gel for Adhesion of Facial Prostheses

Abstract

Although implant-supported facial prostheses can achieve good outcomes for esthetic and functional rehabilitation of oral cancer patients, there are many limitations in the application of facial implants such as irradiated bone or cost. We must therefore consider an alternative method for retaining facial prostheses. In this study, the possibility of using a self-adhesive sheet of segmented polyurethane gel （GELRODE^Ⓒ, Takiron Co., Ltd., Japan） as an adhesive material for facial prostheses was investigated. The adhesive force of GELRODE to the silicone material （non coated, primer coated and bond coated） and the skin of the forearm was measured. The adhesive force of GELRODE to the bond-coated silicone was higher than that to skin, suggesting that GELRODE is useful for adhesion of facial prostheses.
