Abstract

The nanometer fluorine-containing resin dental material and the preparation method thereof belong to the technical field of photocurable resin dental material and powder dispersion method. The resin dental material is composed of methacrylate monomers, initiators and inorganic fillers. The inorganic fillers contain fluorine-containing glass powder, nano-silica powder, dyes, strontium glass or / and barium glass; nano-YbF3 and Bi2O3 can also be included. The preparation involves silanization treatment of fluorine-containing glass powder and nano-silicon powder, and ultrasonic dispersion technology of nano-silicon powder in an organic medium. The resin dental material of the present invention has biological activity, can resist dental caries, and has relatively ideal effects in properties such as radiation resistance, transparency, tensile strength, wear resistance, density, rheology and the like. In particular, the combination of fluorine-containing glass powder and preferably methacrylate monomers has the best effect on fluorine release and mechanical properties at the same time.

Description

technical field [0001] The invention relates to a novel photocurable resin dental material and a powder dispersion technology used in the preparation of the material. technical background [0002] Modern dental materials generally use polymerizable monomers, most of which are composite materials composed of methacrylates, inorganic fillers and polymerization initiators. Since Rafael L. Bowen invented the BisGMA monomer, this type of material has been developed rapidly. At present, it has been widely used in dental filling materials, crowns, point bridges, admixtures, inlay materials, external inlay materials and artificial teeth and Restoration of porcelain teeth, etc. However, as people's understanding of oral materials gradually deepens, the requirements for dental materials are getting higher and higher. Not only is it required to have specific strength and other functions, but it is also required to be biologically active, anti-bacterial, and anti-dental caries. Theref...
