Abstract
The dental resin modified glass-ionomer composition includes an acidic polymer; an acidic polymerizable monomer selected from 4-(meth)acryloxyalkyltrimellitic anhydride, 4-(meth)acryloxyalkyltrimellitic acid, and a combination thereof; a non-acidic polymerizable monomer; a fluoroaluminosilicate glass filler; water; and at least one polymerization initiator system. The dental resin modified glass-ionomer composition is useful for a dental restorative composition, an endodontic composition, and/or an orthodontic composition, and provides significantly enhanced adhesive property toward tooth structure.
Claims20
