Description

technical field [0001] The invention relates to the technical field of bioactive glass, in particular to a bioactive glass used as a filling in dental operations and a preparation method thereof. Background technique [0002] Bioactive glass is a type of silicate glass with special composition and structure, which has good bioactivity, osteoconductivity and biocompatibility. Glass ceramics is a polycrystalline solid in which the glass phase and crystal phase are uniformly distributed by controlling the crystallization of the matrix glass. Through the heat treatment process, the crystal phase is precipitated. The ceramic material has a certain strength and toughness, and at the same time contains a certain amount of glass phase, which makes it have better light transmission performance, and can better simulate and restore the color and light transmission of natural teeth. Fluorapatite crystals are similar to hydroxyapatite crystals in natural tooth enamel and are excellent d...
