Patent ID: 8029286

Claim:
A method of bonding a dental material to a dental structure, the method comprising: applying a self-etching, non-aqueous adhesive to a wet, unetched dental structure surface under conditions effective to cause the adhesive to etch the dental structure surface; wherein the non-aqueous adhesive is substantially free of organic solvents, containing less than 1% by weight organic solvent, and wherein the non-aqueous adhesive comprises an ethylenically unsaturated compound with acid functionality, an ethylenically unsaturated compound without acid functionality, an initiator system, and a surfactant; drying the dental structure surface to form a first adhesive layer thereon; optionally applying a second adhesive over the first layer to form a second adhesive layer thereon; applying a dental material to the dental structure surface having the first adhesive layer and optionally the second adhesive layer thereon; and hardening at least one of the adhesive layers under conditions effective to form a bond between the dental material and the dental structure.
