Artificial bone
Artificial Bone
Artificial bone (pronunciation: /ɑːrˈtɪfɪʃəl boʊn/) is a type of biomaterial used to replace human bone in various medical procedures.
Etymology
The term "artificial bone" is derived from the Latin word "artificium" meaning "craftsmanship, craft, or art" and the Old English word "bān" meaning "bone".
Definition
Artificial bone, also known as bone graft substitute, is a synthetic, lab-grown material that mimics the structure and function of natural bone. It is primarily used in orthopedic surgery to replace or augment damaged or diseased bone tissue.
Types
There are several types of artificial bone, including:
- Ceramic-based artificial bone: These are made from calcium phosphate ceramics like hydroxyapatite and tricalcium phosphate.
- Polymer-based artificial bone: These are made from biodegradable polymers such as polylactic acid and polyglycolic acid.
- Composite artificial bone: These are made from a combination of ceramics and polymers to mimic the natural composition of bone.
Applications
Artificial bone is used in a variety of medical applications, including:
- Bone grafting: Artificial bone is often used as a graft material in orthopedic surgeries to replace missing bone or to stimulate bone growth.
- Spinal fusion: In spinal fusion surgeries, artificial bone is used to fuse together vertebrae to improve stability and reduce pain.
- Dental implants: Artificial bone can be used in dental procedures to replace missing bone in the jaw.
