Abstract

The invention relates to a method for preparing an anti-secondary caries cavity repairing material, which belongs to the field of medical and dental preparations. The prior fluorine-containing anti-secondary caries composite resin caries filling material has the problems of over-quick fluorine dilution, poor interface compatibility and no rigid support to a caries filling body. The method in the invention aims to solve the problems and comprises the following steps: utilizing a silane coupling agent to perform surface modification on nanometer inorganic powder; under a dark condition, uniformly mixing the modified nanometer inorganic powder with monomers of a bisphenol A glycidyl methacrylate class, diluents of a dimethacrylate triethylene-glycol ester class, light triggers of a camphorquinone class, coinitiators of a dimethylamino ethyl methacrylate class and other materials; and removing bubbles under a vacuum condition. The method of the invention has the key point that the nanometer inorganic powder comprises a fluorine-containing zirconium dioxide nanometer tube which takes up 10 to 80 percent of the percent by weight of the nanometer inorganic powder, and the fluorine-containing zirconium dioxide nanometer tube integrates the functions of fluorine slow release of fluorine anti-secondary caries and structure reinforcement.

Description

technical field [0001] The invention relates to a method for preparing an anti-secondary caries cavity restoration material, which belongs to the field of A61K medical and dental preparations. Background technique [0002] Composite resin is a caries filling material that has been gradually popular in clinical practice. Composite resins for caries filling can be roughly divided into two categories: single-paste composite resins and double-paste composite resins. Accompanied by a certain volume shrinkage, no matter what kind of composite resin is used for caries filling, micro-cracks are likely to occur on the edge of caries-filled fillings, which will cause edge micro-leakage and cause secondary caries. Many studies have shown that if the cavity filling material has the ability to release fluoride ions, the secondary caries at the edge of the cavity filling will be significantly reduced, because the released fluoride ions can diffuse into the adjacent hard tissue of the too...
