Cements from beta dicarbonyl polymers

摘要

The invention provides novel ionomer polymers and cements comprising beta -dicarbonyl groups. The invention has particular utility as filling materials for restoring teeth and for cementing inlays and crowns into place in the tooth, providing a base or a lining in a tooth cavity, and as adhesives or sealants. The invention provides ionomer cement systems that achieve increased resistance to water absorption and solubility.
