Abstract

The invention discloses antibacterial monomer-containing repairing composite resin for dentistry and a preparation method thereof. The composite resin comprises 1-25% of bisphenol A-glycidyl methacrylate, 1-20% of carbamic acid ester dimethacrylate, 4-15% of triethylene glycol dimethacrylate, 1-10% of methylacryloyl oxygen dodecylpyridinium bromide, 55-80% of silicon dioxide, 0.5-1% of camphorquinone and 0.5-1% of N, N-dimethylamino ethyl methacrylate. The methylacryloyl oxygen dodecylpyridinium bromide in the composite resin is an antibacterial bonding monomer synthesized from antibacterial quaternary ammonium dodecylpyridine and polymerizable methylacryloyl groups and can be polymerized with other monomers, so that the composite resin has an antibacterial effect, and the bonding effect between the resin and teeth can be enhanced.

Description

technical field [0001] The invention relates to a dental restoration material, in particular to a dental restoration composite resin containing an antibacterial monomer and a preparation method thereof. Background technique [0002] The World Health Organization lists dental caries, cardiovascular and cerebrovascular diseases, and tumors together as the three major non-communicable diseases that need to be prevented and controlled in the 21st century. Caries is a bacterial disease, the main common disease of the oral cavity, and one of the most common diseases of human beings. It can be secondary to pulpitis and periapical 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. [0003] Dental restoration materials have a history of hundreds of years, and ...
