| 摘要 |
The present invention provides a resin-based dental restorative that exhibits high condensability, low volumetric shrinkage and low shrinkage stress. To this end, one or more of a rheological modifier, dispersant and fluorocopolymer are 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.
