Abstract
The present application relates to a polymerizable dental adhesive system formulated for effective and durable bonding of zirconia based materials and restorations to dental resins and dental surfaces. According to one embodiment, a polymerizable dental adhesive system comprises a first acidic monomer comprising an ethylenically unsaturated polymerizable group or moiety of the general formula CH═C—C(O)— wherein X is hydrogen, methyl or a lower alkyl group, and the first polymerizable monomer further comprises a phosphoric or phosphonic acid group of general formula —OP(O)(OH), —OP(O)(OH), —C—P(O)(OH)and —C—P(O)(OH), and a second polymerizable acidic monomer comprises an ethylenically unsaturated polymerizable group or moiety of the general formula CH═C—C(O)— wherein X is hydrogen, methyl or a lower alkyl group, and wherein the second polymerizable acidic monomer further comprises a carboxylic acid group of the general formula —C(O)OH.
