Abstract

The invention relates to the technical field of materials, in particular to a dental adhesive composition as well as a preparation method and application thereof. The dental adhesive composition does not contain a polyfunctional (meth) acrylic polymerizable monomer and an expanding monomer of an acidic group; the mass-volume percentage content of the polyfunctional (meth) acrylic polymerizable monomer containing no acidic group is 30-70%, and the mass-volume percentage content of the expanding monomer is 5-30%. Aiming at the problem that the dental adhesive taking methacrylate resin as a resin matrix is easy to generate micro-leakage and secondary caries, the expansion monomer, the fluoride and the mineralizer are added into the adhesive, so that the polymerization shrinkage of a system is effectively reduced, the acid resistance and antibacterial ability of teeth are improved, and the micro-leakage and secondary caries phenomena are remarkably improved.

Description

technical field [0001] The present invention relates to the technical field of materials, in particular to a dental adhesive composition and a preparation method and application thereof. Background technique [0002] Adhesive restoration is a common method in dental treatment, which specifically uses dental adhesives to repair permanent damage such as broken teeth and caries. Dental adhesives can adhere various restorative materials (such as composite resins), restorations (such as crowns, inlays, fixed bridges, etc.), appliance accessories (such as orthodontic brackets), etc. to the pretreated tooth surface Or in the cavity to restore the normal shape and function of the tooth. The use of adhesives can allow doctors to repair teeth without removing too much healthy dental tissue from patients, providing more protection to patients, and the restoration effect is more realistic. Therefore, oral adhesive materials have always been paid attention to. It is one of the importan...
