Anti-bacterial resin composite material for dental department and preparation method of anti-bacterial resin composite material

Abstract

The invention discloses an anti-bacterial resin composite material for the dental department. The anti-bacterial resin composite material is prepared from the following raw materials in parts by weight: 30-45 parts of bisphenol A-glycidyl methacrylate, 10-30 parts of triethylene-glycol dimethacrylate, 4-12 parts of 1,6-hexanediol dimethacrylate, 2-8 parts of spiro orthoester, 0.5-2 parts of polytetrafluoroethylene, 1-3.5 parts of camphorquinone, 3-10 parts of tetrapod-like zinc oxide whiskers, 2-10 parts of modified nano titanium dioxide, 2-12 parts of chitosan, 1-2.5 parts of diethylenetriamine, 0.3-1 part of polyvinylpyrrolidone, and 1-2.5 parts of sodium p-tolylsulfinate. For the anti-bacterial resin composite material for the dental department and a preparation method of the anti-bacterial resin composite material for the dental department, the preparation method is simple, the operation is easy, and the obtained anti-bacterial resin composite material for the dental department is high in strength, has good attaching degree with teeth, and is excellent in antibacterial property.

Description

technical field [0001] The invention relates to the technical field of resins, in particular to a dental antibacterial resin composite material and a preparation method thereof. Background technique [0002] Dental caries is the lesion of tooth hard tissue caused by multiple factors in the oral cavity, in which the demineralization of inorganic matter and the decomposition of organic matter are its main manifestations. As the time of carious lesions increases, the teeth begin to change from initial color to final substantial lesions. Dental caries and some diseases caused by dental caries are basically not harmful to human life, so human beings tend to ignore these diseases, but if dental caries is not treated early, it may cause some diseases, such as pulpitis, periodontitis, etc., if Severe disease can lead to other diseases, further destroying human health. With the development of economy and technology, dental caries restoration becomes more and more serious, and the re...

AI Technical Summary

Problems solved by technology

Since the oral cavity is a bacterial environment, bacteria are easy to adhere and accumulate on the resin, forming plaque, leading to diseases such as mucositis or dental caries, thus making the filling treatment ineffective

As people have higher and higher requirements on the quality of dental resins, the antibacterial properties of existing dental resins are not very good, which limits the application of dental resins
