Bioactive glass
Bioactive Glass
Bioactive glass (pronunciation: /ˈbaɪoʊˈæktɪv ɡlæs/) is a type of glass that has a unique ability to bond with living tissues. This property makes it an important material in the field of biomaterials and tissue engineering.
Etymology
The term "bioactive glass" is derived from the Greek word "bios" meaning life, and the English word "active", referring to its ability to interact with living tissues. The word "glass" comes from the Old English "glaes", referring to the material's transparent nature.
Definition
Bioactive glass is a type of glass that, when implanted in the body, triggers a biological response at the interface of the implant which results in the formation of a bond between the tissues and the implant. This is due to the release of ions such as silicon, calcium, and phosphorus which stimulate the body's natural healing process.
Related Terms
- Bioglass: A specific type of bioactive glass that was the first man-made material to bond with living tissues.
- Hydroxyapatite: A naturally occurring mineral form of calcium apatite that is often used in conjunction with bioactive glass in bone grafts.
- Osseointegration: The process by which an artificial implant anchors to bone, a process that bioactive glass can facilitate.
- Silicate glass: A type of glass that is a major component of bioactive glass.
Applications
Bioactive glass is used in a variety of medical applications, including bone grafts, dental implants, and as a coating for orthopedic implants. It is also used in drug delivery systems due to its ability to be modified to release specific ions.
