Abstract

The invention provides a dental resin adhesive containing unsaturated fatty acid polyphenolic amide derivatives. The dental resin adhesive is prepared from 20-70 parts by mass of core functional monomers, 20-70 parts by mass of an auxiliary functional monomer, 10-30 parts by mass of an initiating system and a dissolved quantity of solvent, wherein the core functional monomers comprise N-(3,4-dihydroxyphenethyl) methacrylamide, N-(3,4-dihydroxyphenethyl) acrylamide, N-3,4-dihydroxybenzoyloxy ethyl methacrylamide, N-3,4-dihydroxybenzoyloxy ethyl acrylamide, N-3,4,5-trihydroxybenzyl methacrylamide, N-3,4,5-trihydroxybenzyl acrylamide, N-3,4,5-trihydroxybenzoyloxy methacrylamide and the like; the auxiliary functional monomer is methacryloyloxyethyl phosphorylcholine or acryloyloxyethyl phosphorylcholine. The dental resin adhesive is high in adhesion strength and good in stability.

Description

technical field [0001] The present invention relates to an adhesive, in particular to a dental resin adhesive. Background technique [0002] The minimally invasive restoration of tooth defects based on composite resin bonding is one of the characteristics of the development of modern dentistry. Composite resin not only has good wear resistance, but also has excellent color, which is close to the color of tooth tissue after curing; and has good immediate and short-term bonding effect; widely used in restoration. [0003] Dentin is composed of about 50% (volume fraction) of inorganic matter and 30% (volume fraction) of organic matter, and the organic matter mainly contains a large amount of type I collagen fibers. During resin bonding, the dentin is first removed to expose the collagen fiber network, and the resin penetrates into the collagen fiber network to solidify, that is, a "hybrid layer" is formed. This mechanical locking force is the main component of the bonding for...
