Abstract
Effect of the Addition of Polyamide (Nylon 6) Micro-Particles on Some Mechanical Properties of RTV Maxillofacial Silicone Elastomer Before and After Artificial Aging
Highlights
Patients with facial defects may suffer from embarrassment and always feel constrained and diminished on both physical and psychological levels
The aim of this study was to evaluate the effect of adding Polyamide-6 (Nylon-6) on the tensile strength, elongation percentage, tear strength, hardness and surface roughness of A-2186 room temperature vulcanized (RTV) silicone elastomer before and after accelerated artificial aging
This study investigated some mechanical properties of A-2186 Platinum RTV silicone elastomer (Factor II Inc., Lakeside, AZ, USA) before and after accelerated artificial weathering
Summary
Patients with facial defects may suffer from embarrassment and always feel constrained and diminished on both physical and psychological levels. Prosthetic restoration for patients suffering from facial deformities may work as a psychological therapy and considered satisfactory, allowing these. The goal of prosthodontic rehabilitation is not expanded by the restoration of function and esthetic ; a tremendous increase in using different types of maxillofacial materials is noticed to improve these goals.[3,4] Silicone elastomer can be considered as the most appropriate material for fabricating facial prostheses; it gained a wide clinical acceptance due to its biocompatibility, low chemical reactivity, ease of manipulation, and optical transparency which facilitates the pigmentation of silicone for simulating skin tone.[5] its mechanical properties do not fulfill the ideal requirements, resulting in a reduction in the clinical longevity of the prosthesis fabricated from this material. Reinforcement of this material may become mandatory to overcome its deficiencies.[6]
