    摘要： Dental composite compositions, restorative compositions, and methods for their use are provided. The compositions can contain (a) from about 1 to about 35 weight percent of a monomer portion containing at least one monomer having a functional group capable of undergoing polymerization; (b) from about 75 to about 95 weight percent of a filler portion, the filler portion containing at least a spherical filler portion having at least one spherical filler particle component; and (c) from about 0.01 to about 10 weight percent of a polymerization catalyst portion containing at least one catalyst capable of assisting in the polymerization of the functional group of the monomer portion and hardening of the composite after application of the composite to a tooth surface or other dental surface. The spherical filler portion is present in an amount sufficient to reduce shrinkage of the composite after polymerization to about 1.8 percent or less. Compositions according to the invention are useful in Class I, II, IV, V, Core build-ups, and other types of dental restorations where maximum strength and polishability are desired. Methods for using such compositions in such restorative procedures are also provided.
