What are Bioactive Glass Ceramics ?
Bioactive glass ceramics from the SiO2, CaO P2O5 family can develop a chemical bond with living hard tissues though the development of a surface layer of carbonated hydroxyapatite. When these materials are exposed to tissue fluid, bioactive glasses are covered by silica rich gel on top of which calcium phosphate rich layer is formed. The calcium phosphate rich layer promotes absorption and concentration of osteoblast cells to form an extra cellular matrix and mineralization.
