Cerâmicas bioativas: estado da arte Bioactive ceramics: state of the arts
<abstract language="eng">Bioactive glasses undergo corrosion with leaching of alkaline ions when exposed to body fluids. This results in the spontaneous formation of a layer of hydroxyapatite (HA), the mineral component of natural bone, which in turn can induce bone growth in vivo. T...
