Abstract

The invention includes a new photopolymerizable resin system for dental restorative materials. The resin system utilizes a thiol-ene component as the reactive diluent in dimethacrylate systems. The ternary resin system comprises a thiol monomer, an ene monomer and a dimethacrylate monomer. The system of the invention has enhanced overall functional group conversion, improved polymer mechanical properties, and reduced shrinkage stress of the ternary system when compared to either traditional dimethacrylate or thiol-ene resin systems.
