Bioactive glasses have many applications but these are primarily in the areas of bone repair and bone regeneration via tissue engineering:[1]
Synthetic bone graft materials for general orthopaedic, craniofacial (bones of the skull and face), maxillofacial and periodontal (the bone structure that supports teeth) repair, chronic osteomyelitis (S53P4 is the only bacterial growth inhibiting bioactive glass). These are available to surgeons in a particulate form
Cochlear implants
Bone tissue engineering scaffolds. These are being investigated in many forms, in particular as porous (contains pores into which cells can grow and fluids can travel) 3-dimensional scaffolds
Treating dentine hypersensitivity and promoting enamel remineralization
