Abstract

The invention relates to a nano fluorine-containing resin dental material and a preparation method thereof and belongs to the technical field of light-cured resin dental materials and power dispersion methods. The resin dental material consists of a methacrylate monomer, an initiator and an inorganic filler, wherein the inorganic filter contains fluorine-containing glass powder, nano silicon powder, a pigment, strontium glass or / and barium glass and may contain nano YbF3 and Bi2O3. The preparation of the nano fluorine-containing resin dental material involves the silylanization of the fluorine-containing glass powder and the nano silicon powder and the technology for the ultrasonic dispersion of the nano silicon powder in an organic medium. The resin dental material of the invention has bioactivity, can resist dental caries and has ideal radiation resistance, transparency, tensile strength, wear resistance, density, rheological behavior and the like. Particularly, due to the combination of the fluorine-containing glass powder and the methacrylate monomer, excellent fluorine-releasing and excellent dynamic performance is achieved at the same time.

Description

Technical field [0001] The invention relates to a novel light-curing 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 BisGMA monomer, this type of material has been developed rapidly. At present, it has been widely used in dental filling materials, tooth crowns, point bridges, admixtures, inlay materials, external inlay materials, and artificial teeth. Repair of porcelain teeth, etc. But as people gradually deepen their understanding of dental materials, the requirements for dental materials are getting higher and higher. It is not only required to have specific strength and other use functions, but also to have biological activity, anti-bacterial and anti-dental caries, so multifunctional resin m...
