A Comparative Evaluation of the Change in Hardness, of Two Commonly Used Maxillofacial Prosthetic Silicone Elastomers, as Subjected to Simulated Weathering In Tropical Climatic Conditions

Abstract

Abstract - Silicone elastomers have become the materials of choice for fabrication of facial prostheses. However such prostheses need periodic replacement due to the degradation of their physical properties due to weathering of polymers. The effect of environmental factors, disinfection solutions and skin secretions on weathering of silicones has been reported. However, the literature does not report on the comparative evaluation on the change in hardness of two commonly used maxillofacial prosthetic silicone elastomers, cured by different techniques and subjected to tropical climatic conditions. This study provides improved insight and understanding into the behavior of such materials for better material selection and treatment results
