Problems solved by technology

However, although this dental adhesive composition has excellent initial adhesiveness, the adhesive layer and the resin-impregnated layer may deteriorate due to water absorption, and there is room for improvement in long-term adhesive durability.

Abstract

Disclosed is a one-pack dental adhesive composition wherein each component is uniformly mixed, which has excellent adhesive properties and bond durability for tooth material (particularly dentin) and is also highly stable when exposed to ambient light. The composition comprises a polymerisable monomer containing an acidic group (A), a polymerisable monomer containing a fluorocarbon group as shown in Formula 1 (B), water (C) and a polymerisation initiator (D), wherein the content of the polymerisable monomer containing an acidic group (A) is 5.5-35 parts per 100 parts of the total weight. (In the formula, R1 represents a hydrogen atom or a methyl group, and Rf represents a fluoroalkyl group with 1-20 carbon atoms.

Description

technical field [0001] The present invention relates to a composition containing a polymerizable monomer used as a one-component type (one-component type) dental adhesive material. In detail, the present invention relates to a one-component dental bonding material composition, which is used to bond tooth structure (dentin) with dental composite resin, dental resin base component (compomer), dental Bonding of dental restorative materials such as resin cement. Background technique [0002] Dental cements are often used to fill or cover restorations in missing parts of teeth. When the dental bonding material is applied to the tooth structure, especially the dentin, it is important to have a decalcification action for dissolving the dentin surface with an acidic component, a soaking action for the monomer component to penetrate into the collagen layer of the dentin, and a soaking action. The solidification of the monomer components to form a mixed layer with collagen (hereinaf...
