Problems solved by technology

[0003] The method of treating dental caries is mainly to use filling materials for filling, that is, firstly remove the damaged caries, use tools to make a certain shape, fill the filling materials and restore the shape of tooth defects. Currently, silver amalgam and composite resin are commonly used. , due to the toxicity of mercury in amalgam, the commonly used dental filling materials are resin materials. Compared with amalgam filling materials, resin has excellent biocompatibility, mechanical, aesthetic and other properties, and has become a popular choice for various dental tissues. The main way of damage, but because the dental resin is easy to be worn out during use, the caries symptoms will appear again in the caries repair position, so it is necessary to develop a new type of resin material with a long service life and a volume that is not easy to shrink.

Description

technical field [0001] The invention belongs to the field of tooth restoration, and in particular relates to a resin material for tooth filling, and also relates to a preparation method of the above-mentioned resin material for tooth filling. Background technique [0002] Teeth are very important organs of human beings. Dental caries, also known as cavities or tooth decay, is a bacterial disease. If the treatment is carried out, the crown will eventually be completely destroyed and disappear, and you will not be able to chew. [0003] The method of treating dental caries mainly uses filling materials for filling, that is, first remove the damaged caries, use tools to make a certain shape, fill the filling materials and restore the shape of the tooth defect. At present, amalgam and composite resin are often used. , Due to the toxicity of mercury in amalgam, the commonly used dental filling materials are resin materials. Compared with amalgam filling materials, resin has exc...
