Embodiment 1

[0025] Embodiment 1: A light-cured ceramic material for dental restoration, in parts by weight, includes the following components:

[0026] 166 parts of nano-ceramic powder from Nanjing Xiaoke Nano Ceramic Technology Development Co., Ltd.; 5 parts of dispersant; 2 parts of photoinitiator from BASF Group; 20 parts of main monomer; 30 parts of diluted monomer; 1 part of colorant; filler 35 parts; 0.15 parts of fluoride ion source;

[0027] The filling material is composed of silanized and zirconated calcium phosphate, nano zirconia, and nano diamond, and the parts by weight of each component in the filling material are: 0.07 part of calcium phosphate, 0.09 part of nano zirconia, and 0.07 part of nano diamond.

[0028] The invention provides a light-cured ceramic material for dental restoration. The invention adopts nano-ceramic powder, which can effectively enhance the strength, toughness and superplasticity of the material, and add silanization and zirconium during the curing p...

Embodiment 2

[0033] Embodiment 2: A light-cured ceramic material for dental restoration, in parts by weight, includes the following components:

[0034] 177 parts of nano-ceramic powder from Nanjing Xiaoke Nano Ceramic Technology Development Co., Ltd.; 6 parts of dispersant; 1 part of photoinitiator from BASF Group; 40 parts of main monomer; 37 parts of diluted monomer; 1 part of colorant; filler 46 parts; 0.1 part of fluoride ion source;

Abstract

The invention relates to the field of dental restoration materials, in particular to a dental restoration photocuring ceramic material and application thereof. The material is used for restoration of dental caries and tooth defects. The dental restoration photocuring ceramic material is prepared from, by weight, 166-187 parts of nanometer ceramic powder, 5-8 parts of a dispersing agent, 1-2 parts of a photoinitiator, 15-45 parts of a main monomer, 15-45 parts of a diluting monomer, 1-2 parts of a coloring agent, 27-55 parts of fillings and 0.5-1 part of a fluorine ion source, wherein the fillings are prepared from silanized and zirconated calcium phosphate, nano-zirconia and nano-diamond. The material has the advantages of being high in strength and curing speed, stable in curing effect and capable of effectively prolonging the service life.

Description

technical field [0001] The invention relates to the field of oral restorative materials, in particular to a light-cured ceramic material for oral restorative and its application. Background technique [0002] Restorative materials used to repair tooth defects caused by dental caries, trauma, etc. are mainly divided into three categories: alloy materials, porcelain materials and composite resins. Because light-curing composite resin is one of the commonly used filling materials and repair materials in the department of stomatology, and it has a beautiful appearance and is easy to operate clinically, it is more and more widely used in the field of stomatology. [0003] However, with the development and application of ceramic restoration materials in recent years, the properties of oral ceramics have been greatly improved, and they have superior performance in many aspects. However, the molding of ceramics is more complicated, and it is inconvenient to solidify. Can not meet t...
