Bone grafting can also be used to repair inadequate bone structure due to previous extractions, gum disease or injuries. Most grafting can be done with bone from a tissue bank, although in some cases bone taken from the patient can be used as well.
Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, past surgery or congenital defects. Large defects are repaired using the patient’s own bone. This bone is harvested from a number of different sites, depending on the size of the defect. The skull (cranium), hip (iliac crest) and lateral knee (tibia) are common donor sites. These procedures are routinely performed in an operating room and require a hospital stay.
