Patent ID: 8162665

Claim:
A single-part, light-curable, self-adhering dental restorative composition consisting essentially of: (A) one or more first polymerizable monomers consisting of (A1) a first phosphate selected from the group consisting of hydroxyethyl (meth)acrylate phosphate, hydroxypropyl (meth)acrylate phosphate, hydroxybutyl (meth)acrylate phosphate, dipentaerythritol penta(meth)acrylate phosphate, pentaerythritol tri(meth)acrylate phosphate, phenyl (meth)acryloxyethyl phosphate, and a combination thereof, and optionally (A2) a second phosphate 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; (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; and the composition has a shear bond strength of at least 10MPa to both dentin and enamel after being light-cured.
