Problems solved by technology

[0003] The existing patent document CN 108904894 A discloses an antibacterial dental brace, which has a certain antibacterial effect, but about 2-8% of activated carbon powder is added to the raw material, which makes the color of the brace black and cannot achieve a good invisible effect. On the contrary, it will make the color of the teeth more prominent, and the added acrylic resin will irritate the skin after contact with the skin, causing symptoms such as rash, cough, and nausea. Although it inhibits the growth of bacteria in the mouth, it will still cause oral discomfort.

Abstract

The invention mainly relates to the technical field of medical equipment processing and discloses an antibacterial and wear-resistant invisible brace. The antibacterial and wear-resistant invisible brace is prepared from raw materials as follows: 87-91 parts of modified gum dammar, 65-67 parts of polyurethane resin, 14-16 parts of stearic acid, 11-13 parts of Ag-tricalcium phosphate, 8-10 parts ofsodium carboxymethyl cellulose, 3-4 parts of nano-zinc oxide, 2-3 parts of nano-titania and 2-3 parts of polyhexamethylene guanidine. According to the antibacterial and wear-resistant invisible braceprovided by the invention, a method is simple, the raw materials are easy to obtain, the cost is low, and the brace is white, does not affect image during wearing, has high strength and wear resistance, is not required to be taken off during eating and can effectively inhibit germ breeding, so that the brace is simpler and more convenient to use and wear; and after the modified gum dammar and thepolyurethane resin are mixed and molten, the stearic acid is added, the fluidity and smoothness of the material can be improved, and the brace is easy to mold, has higher similarity to real teeth andis attractive and comfortable to wear.

Description

technical field [0001] The invention mainly relates to the technical field of medical equipment processing, in particular to an antibacterial and wear-resistant invisible brace. Background technique [0002] With the improvement of people's quality of life, more and more attention is paid to teeth and oral care. Therefore, the technology of tooth shaping, whitening and oral care is getting higher and higher. Tooth shaping is mainly to correct teeth, and braces are needed during the correction process. Braces are also being continuously improved as a basic tool for correction. In order to consider the aesthetics of patients during the correction process, more and more invisible braces are being prepared and used. [0003] The existing patent document CN 108904894 A discloses an antibacterial dental brace, which has a certain antibacterial effect, but about 2-8% of activated carbon powder is added to the raw material, which makes the color of the brace black and cannot achieve...
