Problems solved by technology

In recent years, a large amount of research work has been carried out around these defects of composite resins. However, the relatively poor mechanical properties and wear resistance of composite resins and the shortcomings of polymerization shrinkage have also been the main factors that limit their wider application.
In most cases, the surface chemical composition and structure of existing composite resin materials are difficult to meet the above requirements, and surface modification treatment, such as graft copolymerization, is usually used to improve its performance

Abstract

The invention discloses a composite material for tooth restoration and a preparation method thereof. The composite material is prepared from the following compositions in parts by weight: polyurethane, calcium hydroxyphosphate, styrene-acrylic emulsion, polyvinylpyrrolidone, a phase-transfer agent, polyglycolic acid fiber, 2-methyl-2-propenoic acid-2-(phosphonooxy)ethyl ester, silver cyclohexanebutyrate, an anti-oxidant, steamed bone meal, zirconia, silica, casein, methoxyphenol, ethanol and double distilled water. Compared with the prior art, the technical scheme comprises the following beneficial effects: the composite material for tooth restoration can be extremely well fused with human teeth, and is high in soundness and not easy to fall off; the composite material is simple to use, free of any toxic and side effects, safe and free of health hidden trouble; and the preparation method is relatively short in flow, simple to operate, low in cost, friendly to environment and high in economic benefit.

Description

technical field [0001] The invention relates to a composite material for tooth restoration and a preparation method thereof. technical background [0002] Tooth cavity treatment is called cavity filling, commonly known as tooth filling. The purpose of caries treatment is to stop the development of caries, restore the shape of the tooth, such as the reconstruction of the cusp and adjacent points; restore the function of the tooth; and protect the pulp tissue at the same time. If caries in the neck of the tooth is not treated in time, it will be allowed to develop under the gingival margin, and after the formation of brown-black caries, because the edge is not neat and sharp, it will often stimulate the gums, causing ulcers and bleeding. Cavities are one of the local causes of bleeding gums. According to the different conditions of caries, carious tissue grinding method, drug therapy, remineralization method, filling method and restoration method are adopted respectively. Th...
