Problems solved by technology

[0008] The technical problem to be solved by the present invention is to solve the problem of unstable release of fluorine from inorganic fluorine salts in the existing fluorine-doped composite resins for caries filling, and the impact on the composite resin caused by the naked doping of inorganic fluorine salts. In order to solve the problem of reducing the overall strength, toughness and wear resistance, a new fluorine-doped composite resin material for caries filling is developed to help prevent secondary caries

Abstract

The invention relates to a fluoridated dental composite resin material contributing to resisting secondary caries, and belongs to the field of dental preparations. The conventional simple villiaumite-blended composite resin caries-filling material has the problems of too quick fluorine release, poor interfacial compatibility and no rigid support for a caries-filling body, and the scheme aims to solve the problems. The fluoridated dental composite resin material comprises the following components in percentage by weight: 20 to 85 percent of nano inorganic powder of which the surface is modified by a silane coupling agent, 8 to 70 percent of bisphenol A glycidyl methacrylate resin monomer, 5 to 25 percent of triethylene-glycol dimethacrylate diluent, 0.25 to 2 percent of camphorquinone photoinitiator, and 0.5 to 3 percent of dimethylamino ethyl methacrylate coinitiator; and importantly, the nano inorganic powder comprises 10 to 80 weight percent of fluorine-carrying mesoporous silica microspheres which can slowly release fluorine and strengthen the composite resin.

Description

Technical field [0001] The invention relates to a fluorine-containing dental composite resin material that helps resist secondary caries and belongs to the field of A61K medical and dental preparations. Background technique [0002] In view of its comprehensive advantages, composite resin is a dental caries-filling material that has gradually become popular clinically. [0003] Composite resins for caries filling can be roughly divided into two types: single-paste type composite resins and double-paste type composite resins. The difference between them is only in the initiation of the cross-linking curing reaction. Both types of composite resins are in the curing process. Accompanied by a certain volume shrinkage, no matter which composite resin is used for caries-filling operations, micro-cracks are prone to occur at the edges of the caries-filling body, and this causes micro-leakage at the edges, which in turn leads to secondary caries. [0004] Many studies have shown that if the...
