Problems solved by technology

However, the bonding property of light-cured composite resin is poor, and the volume and thermal expansion coefficient of light-cured composite resin are inconsistent with those of the tooth body, so it is prone to instability between teeth, gaps on the periodontal edge, etc., which will cause subsequent pulpitis and tooth decay. Body looseness and other issues
Glass ionomer cement can reduce the occurrence of subsequent pulpitis, but its own low hardness and poor wear resistance limit its application to a certain extent

Abstract

The invention discloses a dental repairing and filling composition and the preparation method thereof. The dental repairing and filling composition is prepared from the following components: fluorapatite, calcium phosphite, epoxy acrylate, diethyl(2-oxopropyl)phosphonate, poly(ethylene glycol) diacrylate, HEDP, tobermorite, hyaluronic acid, polyether-ether-ketone, strontium hydrogen phosphate, bismuth oxide, beryllium oxide, talcum powder, barium sulfate, benzoyl peroxide, methylated beta-cyclodextrin, sodium carboxymethylcellulose, gelatin, phosphorylcholine and boron trifluoride amine. The bending intensity of the dental repairing and filling composition can reach 86-94 MPa, the flexural modulus can reach 9.8-11.3 GPa, the modulus of compression can reach 6.9-7.5 MPa, the mechanical property is excellent, appearance and color stability to strong tea is higher than 4.5, the appearance beauty can be kept enduringly, the comprehensive performance is excellent, and the dental repairing and filling composition is very suitable for serving as a dental repairing and filling material to be popularized and used extensively.

Description

technical field [0001] The invention belongs to the technical field of biomedical materials, and in particular relates to a dental restoration filling composition and a preparation method thereof. Background technique [0002] Nowadays, with the changes in people's life, eating habits and structure, the wear and tear of oral teeth is becoming more and more serious, and it is more and more common for people to suffer from oral diseases. In many dental restorations, a restorative filling is used. At present, the restoration and filling materials mainly include light-curing composite resin and glass ionomer cement. Among them, the main mechanism of light-curing composite resin is to perform acid etching and decalcification treatment on the surface of dentin and enamel, and then use resin to fill and restore the tooth, and then light-cure layer by layer to form a tooth body with a natural tooth appearance. However, light-cured composite resins have poor adhesion, and the volum...
