ABSTRACT:
Disclosed is a dental composition comprising a (meth)acrylic ester compound as the principal component and containing a polymerization initiator, which is characterized by having incorporated therein a grafted rubber obtained by polymerizing at least one ethylenically unsaturated monomer in the presence of a rubber. This dental composition can be cured to yield a cured product having excellent strength properties and, therefore, is particularly useful in applications such as a molar restoration material and a denture base resin.
