Bionic SiO2 tooth veneering and preparation method thereof

The invention discloses a bionic SiO2 tooth veneering and a preparation method thereof and belongs to the field of dental restoration materials. The method includes: uniformly mixing silicon carbide,epoxy resin, light calcium carbonate, SiO2, Al2O3, silicone powder, BaCO3, B2O3 and ZnO, and performing compression moulding; freeze-drying and pulverizing the mixture, adding carrageenan, chitin, algae fiber, phillygenin, calcium fluoride and hydroxyapatite, adding water and ball-milling the mixture to make slurry; spray-granulating the slurry, and performing compression moulding to prepare a green body, and drying the green body; sintering the green body at 800-1200 DEG C for 1-10 h. By adding the phillygenin, the bionic SiO2 tooth veneering has good adhesive force and stable shape, has smooth surface and is free of irritation on oral cavity. By means of the silicone powder, the bionic SiO2 tooth veneering is improved in bending strength and has better anti-wearing effect. 本发明公开了种仿生二氧化硅牙齿贴面及其制备方法，属于牙齿修复材料领域。该方法包
