Polymeric dental composites modified with carboxy phosphazene methacrylates

Abstract

Oligophosphazenes containing carboxy and polymerizable methacrylate groups were prepared by the reaction of hexa-p-carboxyphenoxycyclotriphosphazene with glycidyl methacrylate. Introduction of these oligomers in an amount of up to 10 wt % into methacrylate filling dental composites enhances their adhesion to tooth tissues and metals by a factor of 5–7 and the compression strength by 20–30%.
