Abstract

The invention provides a tooth bracket-free invisible orthodontic accessory material and a preparation method thereof. The accessory material comprises the following components, by mass, 12-24 parts of hydroxylapatite, 3-10 parts of crystal whiskers, 0.5-5 parts of calcium fluophosphate, 3-11 parts of zirconium oxide, 6-15 parts of amino glucose, 2-7 parts of collagen fibers, 5-13 parts of polylactic acid, 2-9 parts of 2-methyl-1,3-dithiane, 4-12 parts of stannous pyrophosphate, 5-16 parts of PVC resin, 0.3-0.9 parts of calcium stearate, 0.2-0.7 parts of strontium chloride, 0.5-1.5 parts of phosphine oxide, 3-11 parts of benzyl alcohol and 13-23 parts of double distilled water. The accessory material has excellent mechanical performance and integration, has good anti-moth and decorative effects, and has strong toughness, anti-wear property and flexure strength.

Description

technical field [0001] The invention relates to the field of medical dentistry, in particular to a toothless invisible orthodontic accessory material and a preparation method thereof. Background technique [0002] Tooth decay is a bacterial disease, which can be secondary to pulpitis and periodontitis, and can even cause alveolar bone and jaw inflammation. If it is not treated in time, the lesion will continue to develop, forming cavities, and eventually the crown will be completely destroyed and disappeared. The final result of its development is tooth loss. Dental caries is characterized by high incidence and wide distribution. It is the main common disease of the oral cavity and one of the most common human diseases. The World Health Organization has listed caries as one of the three major human diseases for prevention and treatment along with tumors and cardiovascular diseases. [0003] Tooth decay will not only affect the appearance of people, but also cause toothache ...
