Patent ID: 7946850

Claim:
A single-part, light-curable, self-adhering dental restorative composition consisting essentially of: (A) one or more first polymerizable monomers selected from the group consisting of glyceryldi(meth)acrylate phosphate, bis{hydroxyethyl(meth)acrylate}phosphate, and a combination thereof; (B) one or more second polymerizable monomers having a molecular weight of 100-250, at least one hydroxyl group, and at least one ethylenically unsaturated group; (C) one or more third polymerizable monomers having a molecular weight of 270-900, at least two ethylenically unsaturated groups and no acidic functional group; (D) a photo-initiator system having at least one photo-initiator; (E) one or more fillers each having a mean particle size of more than 0.005 microns and less than 70 microns; and (F) optionally one or more ingredients selected from the group consisting of: a colorant, a stabilizer, a UV absorber, a solvent, a fluoride-releasing compound, an antimicrobial additive, and a surfactant; wherein the weight ratio of (A+B):(C) ranges from 30:70 to 90:10; the concentration of component (A) in the restorative composition, excluding fillers, is in the range of 10-50% by weight; the concentration of component (B) in the restorative composition, excluding fillers, is in the range of 15-60% by weight; and the composition has a shear bond strength of at least 10 MPa to both dentin and enamel after being light-cured.
