Silicone Prosthesis Silicone Prosthesis is a common chin pad material, which is suitable for a variety of filling plastic surgery including chin plastic. The manufacturing technology of silicone prosthesis has been developed. The silicone prosthesis made of chin plastic material is non-toxic and harmless, and the human body has little rejection, so it can be used for chin pad. The silicone prosthesis fixed by special methods is not easy to be infected and displaced, and the material itself is easy to carve and shape, and the internal micropores are conducive to the growth of fibrous vascular tissue, which can be fixed on the bone surface with titanium nails.
