Porous bioactive glass bone repair material and preparing method thereof

Abstract

The invention relates to a porous bioactive glass bone repair material and a preparing method thereof. The repair material is prepared from 50-65 parts of glass micro powder, 20-36 parts of urea, 8-18 parts of polyethylene glycol and 6-10 parts of starch. During preparation, the glass micro powder is used as a raw material, a urea, polyethylene glycol and starch mixture is used as a pore-forming agent, a small amount of a binding agent is added, and the porous bioactive glass bone repair material is prepared through compression molding of a performing machine and high-temperature calcination. The prepared repair material has uniform pores, is applied to bone defect repair and bone tissue loss regeneration, increases autogenous bone healing speed and improves bone repair efficiency.

Description

technical field [0001] The invention belongs to the field of bioactive materials, and in particular relates to porous bioactive glass for bone defect tissue repair, filling and tissue engineering repair and a preparation method thereof. Background technique [0002] Bioactive glass has good bioactivity and biocompatibility, and can be used as a material for human tissue repair and regeneration. In the clinical application of bone tissue repair and bone tissue engineering, it can promote the differentiation and proliferation of osteoblasts by activating some genes of osteoblasts, so as to have a good bone repair effect. However, traditional bioactive glass is a dense material with low strength and high brittleness, which affects its wide application in the field of bone repair. Medical research shows that the bioactive glass used for bone filling and repair needs a three-dimensional porous and interconnected pore structure of appropriate size to facilitate the penetration of...
