Abstract

The invention relates to a calcium borate silicate biological material as well as preparation method and application thereof. Pure-phase calcium borate silicate Ca11Si4B2O22 powder is synthesized by a solid-phase synthesis method or a wet chemical synthesis method; the calcium borate silicate powder is pressed and moulded to obtain a calcium borate silicate ceramic block; the calcium borate silicate powder or the calcium borate silicate ceramic block is soaked in a simulated body fluid (SBF) for certain time and mineralized; after a while, a bone-like apatite layer can deposit on the surface of the powder or the ceramic block; researches find that the thickness of mineralized hydroxyapatite increases along with the increase of the soaking time. The calcium borate silicate powder or the ceramic material prepared through the preparation method has good biological performance, is a biological and medical material with very high potential, and can be used as a bone tissue repairing and filling material and a tooth repairing material.

Description

technical field [0001] The present invention relates to calcium borosilicate biomaterials, preparation methods and applications thereof, in particular to a biomineralization material capable of adsorbing hydroxyapatite (HAP) and inducing remineralization of hydroxyapatite and a preparation method thereof It belongs to the interdisciplinary field of material science, bionics and biomedicine. It involves a method that simulates the internal environment of the human body. The biomineralization method is used to spontaneously deposit hydroxyapatite in aqueous solution. The obtained coating not only has good Biological activity, but also can significantly improve the binding force of the coating. Background technique [0002] With the improvement of people's awareness of oral health, the demand for clinical technology to treat dental diseases caused by demineralization has increased rapidly. Organic matrices such as enamel matrix protein and dentin phosphoprotein in the human bo...
