Abstract

A dental filling resin material and a preparation method thereof are provided. The material is made of the following components in parts by weight, 15 to 30 parts of polyvinyl chloride resin, 5 to 11parts of propylene glycol alginate, 6 to 10 parts of dodecylamine oxide, 15-18 parts of polyhydroxyethyl methacrylate, 10-15 parts of chitin, 2-5 part of fimbrin, 10-11 parts of chitosan fiber, 10-12parts of cystine diethyl ester, 5-6 part of anti-caries agent, 4-6 parts of nano silver powder, 5-7 parts of paeonol, 10-12 parts of antioxidant, 5-6 parts of nano filler, 2-3 parts of stabilizer and15-20 parts of double distilled water. The filling resin material has excellent surface hardness and good abrasion resistance, and is easy to be polished. An anti-caries agent is added into the filling resin material in the invention, which can effectively prevent dental caries; The dental filling resin of the invention is added with nano silver salt, which can effectively inhibit oral bacteria; The filling resin material does not contain heavy metals and is environmentally friendly; And the preparation method is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of biomedical materials, and in particular relates to a dental filling resin material and a manufacturing 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 i...
