Abstract :

Background: Maxillofacial prosthetic materials must possess optimal physical, esthetic, and biological properties that remain stable over time to ensure patient acceptance and long-term clinical success. Silicone elastomers are the most commonly used materials due to their favourable characteristics; however, their performance remains limited by environmental degradation, particularly from ultraviolet radiation and thermal effects, leading to mechanical deterioration and color instability. Over time, various materials and technologies—including silicone copolymers, polyurethane elastomers, and more recently, three-dimensional (3D) printing with CAD integration—have been explored to enhance the durability, customisation, and esthetic outcomes of facial prostheses.

Aim of the Study: This study aimed to evaluate the effect of incorporating different weight percentages of pomegranate peel powder on the surface hardness of VST-50 room temperature vulcanised (RTV) maxillofacial silicone.
