Dental filling material of bioactive glass material, and filling method for dental filling material

Abstract

The invention belongs to the technical field of dental filling materials, and particularly relates to a dental filling material of a bioactive glass material and a filling method for the dental filling material. The dental filling material comprises the following raw materials in parts by weight: 36-45 parts of di-methylacrylic acid esters, 18-20 parts of inorganic fillers, 20-22 parts of a lecithin modified porous bioactive glass and chitosan compound material, 15-18 parts of graphene embed modified nanometer zirconium oxide, 1.5-3.5 parts of a photoinitiator and 0.5-1.5 parts of a stabilizer, wherein the mass ratio of lecithin modified porous bioactive glass to chitosan in the lecithin modified porous bioactive glass and chitosan compound material is 1-1.5:1-2. The dental filling material prepared by the invention has high bending strength and elasticity modulus strength, a friction coefficient is lowered to a high extent, interface bonding strength of the bioactive glass powder andthe chitosan is high, and meanwhile, the dental filling material is endowed with good bacteria resistance and bacteriostasis performance and biocompatibility.

Description

technical field [0001] The invention relates to the technical field of dental restorative materials, in particular to a dental filling material of bioactive glass material and a filling method thereof. Background technique [0002] Dental restoration is to prepare the tooth according to the principles of retention, resistance and protection of the pulp-dentin organ on the basis of removing the damaged or severely weakened tooth tissue; finally, restore its inherent shape and Features. Dental restoration materials are an indispensable material in the process of tooth restoration. This kind of material is not only required to be implanted in the oral cavity, but also required to function stably for a long time in the specific environment of the oral cavity. [0003] After the 1960s, UV curing technology was used in the field of dental restoration materials. UV curing is a curing process that uses ultraviolet light as an energy source to trigger a chemically active liquid for...
