Antibacterial and durable tooth filling composite material and preparation method thereof

Abstract

The invention discloses an antibacterial and durable tooth filling composite material and a preparation method thereof. The composite material is prepared from the following components in parts by weight: 30-40 parts of polymethyl methacrylate, 20-25 parts of hydroxyl calcium phosphate, 13-15 parts of acetoacetoxyethyl methacrylate, 3-8 parts of fimbrin, 1-3 parts of 2-thiol benzimidazole, 5-12 parts of a phase transfer agent, 12-30 parts of glycosaminoglycan, 5-10 parts of steamed bone meal, 4-8 parts of silver cyclohexylbutyrate, 3-5 parts of casein, 4-8 parts of hydroxy anisole, 3-8 parts of an antioxidant, 12-24 parts of sorbitol, 8-23 parts of benzyl alcohol and 25-45 parts of double distilled water. The composite material disclosed by the invention is capable of improving tissue compatibility and blood compatibility, and the composite material is antibacterial, capable of improving mechanical and physical properties, wear-resistant and durable to use; and the preparation method has the advantages of being simple in process, easy to operate, high in yield, low in pollution to environment and the like.

Description

Technical field [0001] The present invention involves a antibacterial durable tooth composite material and its preparation method. technical background [0002] Dental caries are commonly known as insect teeth and tooth decay. They are bacterial diseases. They can secondary toothitis and penetrated periarthritis, and can even cause alveolar bone and mandibular inflammation.If it is not treated in time, the lesions continue to develop, formation of caries, and eventually the crown completely destroys and disappeared. The final result of its development is the loss of teeth.Dental caries are characterized by high incidence and wide distribution.It is the main common disease of the oral cavity and one of the most common diseases of human beings. The World Health Organization has tied it with tumors and cardiovascular diseases as three key prevention and treatment diseases.1. The harm of dental caries to adults: ① often causes inflammation of the tip of the root of the teeth, and the...

AI Technical Summary

Problems solved by technology

②Bad tooth roots cannot chew food; increase the burden on the gastrointestinal tract

③ For the elderly, severe caries can cause most or all of the teeth to be lost, which is not conducive to the health of the elderly

2. Eight major hazards of dental caries in children: ① Tooth defect, involving multiple deciduous molars, can reduce the chewing function; ② Food residues in the caries cavities accumulate and bacteria accumulate, which deteriorates oral hygiene and affects the occurrence of caries in permanent teeth; ③ Apical periodontitis of deciduous teeth affects the germs of the inherited permanent teeth, causing enamel development and normal eruption obstacles; ④The premature loss of deciduous teeth due to caries causes the space between permanent teeth to shrink, and the position of the permanent teeth is abnormal due to insufficient space; ⑤The crowns of deciduous teeth are easily damaged Partial oral mucosal tissue; ⑥Serious caries of deciduous teeth, resulting in reduced chewing function, affecting children's nutritional intake, and affecting growth and development; Focal infection; ⑧ affecting the appearance and correct pronunciation

Among them, silver amalgam is strong, not easy to wear but not beautiful enough, and composite resin is beautiful and close to the natural color of teeth, but its strength is not as good as silver amalgam, and it is easy to wear. In most cases, the surface chemical composition and structure of existing composite resin materials are very different. It is difficult to meet the above requirements, and surface modification treatment, such as graft copolymerization, is usually used to improve its performance
