Abstract

The invention discloses a high-bending-strength oral cavity repair material and a preparation method thereof, wherein the oral cavity repair material comprises the following components by the mass percentage: 8-12% of zinc oxide, 1-2% of cerium oxide, 0.5-1% of tantalum oxide, 0.2-0.5% of niobium oxide, 2-3% of borax, 1-3% of polyether-ether-ketone, 2-4% of sodium fluoride, 2-4% of sodium monofluorophosphate, 2-3% of sodium stannate, 8-10% of nano montmorillonite, 0.1-0.2% of triethylene diamine, 0.1-0.2% of resorcinol monobenzoate, and the balance zirconium oxide. With zirconium oxide as the main component, with zinc oxide as the supplement, with addition of cerium oxide, tantalum oxide and niobium oxide, the basic mechanical strength of the obtained oral cavity repair material is ensured, borax plays a bactericidal effect, polyether-ether-ketone enhances the wear resistance and corrosion resistance of the oral cavity repair material, sodium fluoride, sodium monofluorophosphate and sodium stannate synergetically enhance the bactericidal effect, nano montmorillonite helps all the components be evenly dispersed so as to improve the mechanical properties of the obtained material, and triethylene diamine and resorcinol monobenzoate help to improve the light stability of the product.

Description

technical field [0001] The invention relates to an oral restorative material, in particular to an oral restorative material with high bending strength and a preparation method thereof. It belongs to the field of dental technology. Background technique [0002] Oral restoration refers to the treatment of soft and hard tissue defects in the oral cavity and maxillofacial region using artificial restorations, and also includes the treatment of periodontal disease and temporomandibular joint disease through restoration methods. With the improvement of living standards and the diversification of diet, there are more and more patients with tooth loss caused by dental caries, periodontitis and tooth damage in my country. Therefore, the development of oral restorative materials and products has higher and higher requirements both in quantity and quality. [0003] The structure, color and texture of ceramic materials are similar to human teeth, and they have good biocompatibility. T...
