Bioactive Glass

Bioactive glasses are a group of surface reactive glass-ceramic biomaterials and include the original bioactive glass, Bioglass. The biocompatibility and bioactivity of these glasses have led them to be investigated extensively for use as implant devices in the human body to repair and replace diseased or damaged bones. Bioactive glasses are considered highly reactive surfaces formed by melt or sol–gel techniques. Bioactive glass forms a hydroxy-carbonated apatite layer when immersed in biological fluid, which enhances protein adsorption to the surface of the implant and integration with surrounding bone. Bioactive glasses are amorphous silicate-based materials which are compatible with the human body, bond to bone and can stimulate new bone growth
