<p>Organopolysiloxane elastomers comprising copolymers of dimethyl and methylvinyl siloxanes provide improved facial and dental prosthetic materials, and are especially useful in preventing and treating chronic tissue irritation due to hard dental polymers. They are effectively bonded to polymeric and metallic substrates as denture liners, obturators, maxillofacial prosthetic devices and appliances with a group of trifunctional silane coupling agents.</p> |
