Benefits of technology

"The present invention provides a composition for dental applications that contains a bifunctional polymerizable monomer and water. The monomer has polymerizable groups and hydroxyl groups, and the composition contains 6 to 2000 parts by weight of water per 100 parts by weight of the monomer. The composition has excellent curability and adhesive properties, and high penetrability into dentin and bond strength and durability with respect to tooth structures. The composition can be used as a dental composition, primer, bonding material, composite resin, or cement."

Problems solved by technology

This composition is, however, not necessarily excellent in penetrability into a collagen layer of dentin and may cause a reduction in bond strength, and therefore improvement in this respect has been desired.

Abstract

The present invention provides a composition suitable for a dental composition. The present invention is a composition containing: a polymerizable monomer (A) having an unconjugated carbon chain with at least four carbon atoms bonded continuously, at least two polymerizable groups, and at least two hydroxyl groups; and a water (B). The composition contains 6 to 2000 parts by weight of the water (B) with respect to 100 parts by weight of the whole amount of polymerizable monomer components. When suitable components are added to this composition, the resultant composition can be used suitably for dental materials such as a primer, bonding material, composite resin, and cement.

Description

TECHNICAL FIELD[0001]The present invention relates to a composition containing: a bifunctional polymerizable monomer having polymerizable groups and hydroxyl groups; and water.BACKGROUND ART[0002]When a lost part of a tooth is filled or covered with a restorative material, generally a dental adhesive is used. A known dental adhesive is one containing a polymerizable monomer having a polymerizable group and a hydroxyl group.[0003]For example, WO 2004 / 047773 describes a dental adhesive composition characterized by containing a polyfunctional polymerizable monomer that is an ester compound of polyhydric alcohol having 3 to 6 carbon atoms and a plurality of (meth)acrylic acids and that has one to two hydroxyl groups, a monofunctional (meth)acrylate having no hydroxyl group in the molecule, a polymerizable monomer having an acidic group in the molecule, an organoboron compound as a curing agent, and a filling material. This describes that the addition of a small amount of the above polyf...
