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.

Abstract

The invention discloses a resin material for filling teeth. The resin material is prepared form the following components in percentage by mass: 20-30% of calcium hydroxyphosphate, 10-15% of polymethylacrylate, 5-10% of triethyl citrate, 5-10% of diethyldodecylphosphonate, 10-15% of calcium alginate, 2-8% of an antibacterial, 5-10% of an antioxidant, 1-3% of a stabilizer and 20-25% of double distilled water, and the sum of the mass percentages of the components is 100%. The invention further specifically discloses a preparation method of the resin material for filling the teeth. The prepared resin material for filling the teeth has good compressive strength and hardness, does not contain heavy metals, is environmentally friendly, has the simple and convenient preparation method, and is easy to popularize.

Description

technical field [0001] The invention belongs to the field of tooth restoration, and in particular relates to a resin material for filling teeth, and also relates to a preparation method of the resin material for filling teeth. Background technique [0002] Teeth are very important organs of human beings. Dental caries, also known as tooth decay or dental caries, is a bacterial disease. It is a decayed lesion of the teeth. A caries cavity is formed on the tooth surface. The caries will become larger and larger, which can completely destroy the tooth. If the caries is not With treatment, eventually the crown will be completely destroyed, and you will not be able to chew. [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 the tooth defect. Currently, silver amalgam and composite resin are commonly used. ,...
