DENTAL ADHESIVE COMPOSITION

摘要

Disclosed is a dental adhesive composition containing a polymerizable monomer having an acidic group, which is applicable to a dental adhesive material or a primer.  The dental adhesive composition has more improved adhesion strength and adhesive durability, and therefore enables the more strong and long-lasting adhesion of a tooth substance to a composite resin or a prosthetic material with excellent adhesive durability. The dental adhesive composition comprises a polymerizable monomer component and an ion of a Group-IV element as basic components, wherein a polymerizable monomer having a hydrogen phosphate diester group (e.g., bis(2-methacryloyloxyethyl) hydrogen phosphate, 2-methacryloyloxyethyl phenyl hydrogen phosphate) makes up at least 10 mass% of the polymerizable monomer component, and wherein the content of the ion of the Group-IV element (e.g., a titanium ion, a zirconium ion) in the composition is 0.1 to 1.0 by mole relative to the content of the hydrogen phosphate diester group of the polymerizable monomer having the hydrogen phosphate diester group.
