Contact cure dental post cement and method of placing a dental post

Abstract

Securing a dental post or a crown or bridge onto the dentin portion of a prepared tooth by utilizing a no-mix, two component, self-curing cement wherein the first component of the cement is applied to the interior dentin surfaces of a post hole, or onto the dentin surface of the tooth receiving the crown or bridge, and applying the second component of the cement onto the surface of a post, or crown or bridge so that when the post or crown or bridge is fitted onto the exposed dentin of a prepared tooth, the complementary components of the cement immediately chemically set to firmly secure the post, crown or bridge onto the prepared tooth. The respective components of the no-mix, two component, self-curing cement formulation for practicing the method require that each include a methacrylate resin. One of the components also includes an aromatic tertiary amine and the other component includes an organic peroxide. At least one or both of the components also includes hydroxyethyl methacrylate or hydroxypropyl methacrylate or other hydrophilic monomers. Additives such as thickeners, fillers, fluoride salts, and polymerization inhibitors may also be included in one or the other component.
