The present invention provides a resin-based dental restorative that exhibits high condensability, low volumetric shrinkage and low shrinkage stress. To this end, a fluorocopolymer of a fluoroolefin, a cyclohexyl vinyl ether, an alkyl vinyl ether and a hydroxyalkyl vinyl ether is mixed with a methacrylate resin and a fine mineral filler in amounts effective to improve the condensability of the resulting composite to achieve amalgam-like condensation, to reduce the volumetric shrinkage to less than about 2% during polymerization, to improve wear resistance, and to provide a composite with generally improved physical properties.
