Abstract

The invention relates to a tooth filling material and a preparation method thereof. The tooth filling material includes, by mass, 15-35 parts of glycidyl methacrylate, 10-25 parts of Arabic gum, 5-20 parts of glass powder, 5-15 parts of silicon dioxide, 3-12 parts of nano montmorillonite, 1-6 parts of calcium carbonate, 0.5-3 parts of 1,6-hexanediol diacrylate, 0.8-3.5 parts of dicumyl peroxide, 0.3-1.5 parts of triethylene diamine, 0.2-1 part of EDTA, 0.2-1.2 parts of an organic tin stabilizer, 3-10 parts of zinc phosphate cement, and 0.1-0.5 parts of resorcinol monobenzoate. The tooth filling material has excellent mechanical performance and polishing performance, has the similar gloss and the similar coefficient of thermal expansion of a tooth, can effectively prevent edge micro-leakage and heat conductivity, has a good hole filling effect and is long in service life.

Description

technical field [0001] The invention relates to the technical field of dental materials, in particular to a tooth filling material and a preparation method thereof. Background technique [0002] In life, many people are facing dental problems, such as tooth decay, dental plaque, tooth fracture, etc. are common situations. Clinically, doctors often choose different materials to fill the cavity according to the location of the affected tooth, the location of the cavity, the magnitude of the occlusal force, as well as the patient's health and aesthetic requirements. Currently, the commonly used materials are: silver amalgam, composite Resin and glass ionomer complex. [0003] Composite resin materials are mainly composed of resin matrix and inorganic fillers. It has greater tensile strength and less expansion, shrinkage and deformation during curing. Its most prominent advantage is aesthetics, which can provide the best color matching with adjacent teeth. In the past, compos...
