bioglass

(bī'ō-glas),
A fused silica-containing aluminum oxide that has a surface-reactive glass film compatible with tissues; used as a surface coating in some types of medical and dental implants.
A type of bioactive glass (45S5 glass), composed of calcium salts, phosphorous, sodium salts and silicates—essential elements of mineralized bone—which bonds with bone and promotes bone regeneration
Indications Mandibular augmentation, repair of damaged middle ear
Pros Low bioactivity
Cons Mechanical weakness, low fracture resistance
