Abstract

The invention provides a composite tooth filling material and a preparation method thereof. The composite tooth filling material is prepared from, by weight, 20-40 parts of polyacrylic resin, 5-11 parts of polymethyl hydroxyethyl acrylate, 6-10 parts of dodecyl amine oxide, 15-18 parts of polymethyl hydroxyethyl acrylate, 2-5 parts of chitin, 10-11 parts of chitosan fibers, 10-12 parts of cystinediethyl ester, 1-3 parts of cyclohexylbutyric acid silver salt, 4-6 parts of nano-silver powder, 5-7 parts of paeonol, 5-10 parts of deep sea mud, 10-12 parts of antioxidants, 5-6 parts of nano-fillers, 2-3 parts of stabilizers and 15-20 parts of double distilled water. The tooth filling resin material has excellent surface hardness and good wear resistance, is free from heavy metal and environmentally friendly and has excellent antisepsis and anti-inflammation functions, surface polishing treatment is easily performed, and the preparation method is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of biomedical materials, and in particular relates to a composite dental filling material and a preparation method thereof. Background technique [0002] Teeth are the organs that humans use to chew food. Teeth are the hardest organ in the human body. Generally speaking, teeth are white and hard in texture. The various shapes of teeth are suitable for many purposes, including tearing, grinding food. Teeth are the hardest organs in the human body, and their main component is basic calcium phosphate. [0003] Dental caries, also known as tooth decay or tooth decay, is a bacterial disease, which can be secondary to pulpitis and periapical periodontitis, and even cause alveolar bone and jaw inflammation in severe cases. 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...
