Major & Minor Bone Grafting
Missing teeth over a period of time can cause your jaw bone to atrophy, or resorb. This often results in a poor quality and quantity of bone that is not suitable for the placement of dental implants as well as long term shifting of remaining teeth and changes to facial structure. Often patients in these situations are not candidates for dental implants.
Fortunately we often have the ability to grow bone where it is needed. This not only gives us the opportunity to place implants of proper length and width in the correct restorative positions, but it also gives us a chance to restore functionality and aesthetic appearance.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip or tibia (below the knee). Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum tissues to protect the bone graft, as well as 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, tumor surgery, or congenital defects. Large defects are often repaired using the patient’s own bone. This bone is harvested from a number of different areas depending on the size needed. The skull (cranium), hip (iliac crest), and lateral knee (tibia), are common donor sites. These procedures are often performed in an operating room in a hospital setting, but sometimes can be completed in our office with our Ambulatory Surgery Center.
