Abstract

The invention discloses an oral repair material and a preparation method thereof. The oral repair material comprises the following components in percentage by mass: 8-12% of zinc oxide, 1-2% of cerium oxide, 0.5-1% of tantalum oxide, 2-3% of borax, 1-3% of polyetheretherketone, 2-4% of sodium fluoride, 2-4% of sodium monofluorophosphate, 2-3% of sodium stannate, 8-10% of nanometer montmorillonite, 0.1-0.2% of triethylene diamine, 0.1-0.2% of resorcinol monobenzoate and the balance of zirconium oxide. The zirconium oxide is used as a main material, the zinc oxide is used as an auxiliary material, and the cerium oxide and the tantalum oxide are also added, so that the basic mechanical strength of the obtained oral repair material is ensured; the borax achieves a bactericidal effect; the polyetheretherketone improves the wear resistance and the corrosion resistance of the oral repair material; the sodium fluoride, the sodium monofluorophosphate and the sodium stannate are coordinated to improve the bactericidal effect; the nanometer montmorillonite facilitates uniform dispersion of the components so as to improve the mechanical properties of the obtained material; the triethylene diamine and the 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 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. They are the most commonly u...
