Is made of hydroxyapatite, calcium phosphate, calcium sulfate, bioglass or the combination of the above substances. The material does not contain recombinant human bone morphogenetic protein -2(rhBMP-2). Bioglass bone filler is used to fill bone defects caused by trauma or surgery in limbs, spine, pelvis and other parts, and will not affect the stability of bone structure. When bioglass bone filler comes into contact with other liquid drugs, it will generate similar components with silicate and other substances in human bones, such as silicon, sodium and calcium, so as to achieve the purpose of filling.
