Artificial bone is a type of medical device that is used to replace parts of a person's real bones that have been damaged or broken. It is made out of a special type of material that looks and works like real bone, so doctors can use it to help people heal. Artificial bones can be used to help people who have fractures, cracks, or other damage to their bones caused by injury or disease. They can also be used to help people who have had some of their bones removed because of cancer or infection. Artificial bones are usually placed inside the body and can help the damaged bone heal faster and stronger.
