Bone Graft
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone that is obtained is your own bone taken from the jaw or the hip. Sinus bone grafts can be performed to replace the bone in the posterior upper jaw. On occasions, special membranes may be utilised that dissolve under the gum but protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration. Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumour surgery, or congenital defects. Large defects are repaired using the patient’s own bone. The bone is harvested from a number of different sites depending on the size of the defect. The skull (cranium), hip (iliac crest), and ribs are common donor sites. These procedures are routinely performed in an operating theatre and require a hospital stay of usually 48 hours.
