45S5 bioactive glass
Bioactive glass is a kind of important inorganic non-metallic bone, tooth and skin wound repair materials
Bioactive glass is a kind of important inorganic non-metallic bone, tooth and skin wound repair materials, which has achieved good therapeutic effect in clinical application. Micro/nano bioactive glass has significant ectopic osteogenesis characteristics. Through the release of Si and Ca ions in glass particles, it promotes the differentiation of bone progenitor cells into osteoblasts, thus accelerating the formation of new bone, which can be applied to the repair and filling of oral cavity and bone defects.
