Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. However, in some situations the bone loss is severe and requires more advanced bone grafting techniques prior to implant placement. This often occurs when teeth have been missing for years and the jaw has atrophied or when the patient has experienced facial trauma.
In these situations, the bone is either obtained from a tissue bank or your own bone is taken from the jaw.
In addition to this bone, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration. When proteins are utilized, we call this tissue engineering.
