Patent ID: 7498367

Claim:
A method for adhering a prosthetic device to a tooth comprising (1) applying a primer/adhesive with a pH less than 4.5 to a surface of a tooth prepared to receive a prosthetic device, wherein the primer/adhesive comprises (a) an acidic compound, (b) a polymerizable monomer having at least one ethylenically unsaturated group selected from the group consisting of vinyl, acrylate, and methacrylate, and (c) at least one solvent selected from the group consisting of acetone, ethanol, methanol, water, and methyl ethyl ketone, (2) adhering the prosthetic device to the primer/adhesive coated tooth surface using a dental cement composition, and (3) hardening the dental cement composition, wherein the dental cement composition is a two-part composition which comprises (A) 5% (w/w) to 90% (w/w) of at least one polymerizable monomer having at least one ethylenically unsaturated group selected from the group consisting of vinyl, acrylate, and methacrylate; (B) 0.01% (w/w) to 10% (w/w) of at least one compound of structure where each of R1, R2, and R3 may be the same or different and is independently selected from the group consisting of H, alkyl, alkoxyl, aryl, acyl, allyl, pyridyl, —OH, alkenyl, aralkyl, cycloalkyl, and heterocyclic structure containing O, S, or N; (C) 0.01% (w/w) to 10% (w/w) of at least one hydroperoxide compound with at least one hydroperoxide group attached to a tertiary carbon; (D) 5% (w/w) to 95% (w/w) of at least one finely divided filler having a mean particle size less than 50 microns; and (E) 0% (w/w) to 25% (w/w) of at least one component selected from the group consisting of a solvent, a photoinitiator, a stabilizer, an antimicrobial agent, and combinations thereof, wherein component (B) is in a first part of the two-part composition, component (C) is in a second part of the two-part composition, and components (A), (D), and (E) are independently in either the first part and/or the second part wherein the at least one compound of component (B) does not include 1-(2-pyridyl)-2-thiourea.
