preparation example Construction

[0029] In the preparation method of the above-mentioned bioactive glass composition, the target product can be obtained by grinding and pulverizing each component in a set mass ratio. Among them, in order to ensure that the formed water-soluble silicic acid gel has a loose structural state to more effectively induce the formation of hydroxycarbonate crystal nuclei, the bioactive glass gel in this embodiment is the bioactive glass that has been acid-washed and dried in advance. processed. At the same time, in order to facilitate the use and preservation of the bioactive glass composition, it can be further uniformly dispersed in the gel.

[0030] The above-mentioned bioactive glass composition can be applied to oral care products, especially having the effect of tooth restoration and material regeneration. Applicable oral care products include toothpaste, tooth cleaner, mouthwash, functional tooth strips, etc., for example. And, it can be understood that when the bioactive gla...

Abstract

The invention provides a bioactive glass composition, a preparation method and application thereof, comprising 40-70wt% bioactive glass, 30-60wt% bioactive glass silica gel, 0.5-1.5wt% calcium salt and 0.01 wt% ~0.1 wt% phosphate. The technical solution of the present invention can induce the formation of hydroxycarbonated apatite crystal nucleus more effectively through the addition of bioactive glass silica gel. The components with "rapid mineralization" properties are combined into a bioactive glass composition with better rapid mineralization effect, which has a better application prospect in oral care products and other products.

Description

technical field [0001] The invention belongs to the technical field of oral biomedical materials, and in particular relates to a bioactive glass composition, a preparation method and an application of the composition. Background technique [0002] In recent years, more and more bioactive materials have been used in oral care products, greatly enriching the functions and efficacy of these products. Commonly added active materials such as: fluorine-containing salts, active calcium phosphate, bioactive Glass, strontium strengthened glass and other ingredients can effectively improve oral caries, dentin sensitivity and other problems. For example, the preparation and application of a hydrolyzable potassium calcium phosphosilicate active material disclosed in the Chinese authorized patent CN102862985B mentions that the hydrolyzable potassium calcium phosphosilicate material is used in oral care products. [0003] In the prior art, there have been toothpastes that add bioactive g...
