ABSTRACT:
Flexible dental composite compositions and restorative compositions are provided comprising (a) about 2 to 15 weight percent of a flexible monomer portion comprising one or more flexible comonomers of the general formula and R.sup.3 are acrylate or methacrylate functional groups, R.sup.2 is selected from the group of hydrogen, methyl and ethyl, n is from 3 to 5 and z is from about 3 to about 20 and the monomers have average molecular weights from at least about 300 or higher, (b) about 30 to about 80 weight percent of a filler portion, (c) about 18 to 60 weight percent of a comonomer portion comprising one or more comonomers capable of polymerizing with the flexible monomer portion, and (d) a polymerization catalyst system for polymerizing and hardening the composition. Compositions according to the invention are useful in Class V and other types of dental restorations. Methods for using such compositions in such restorative procedures are also provided.
