MAJOR AND MINOR BONE GRAFTING
Missing teeth over a period of time can cause your jaw bone to atrophy, or resorb. This often results in poor quality and quantity of bone suitable for the placement of dental implants as well as long term shifting of remaining teeth and changes to facial structure. Most patients, in these situations, are not candidates for dental implants.
Fortunately, today we 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, 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 or hip . 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 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 repaired using the patient’s own bone. This bone is harvested from a number of different areas depending on the size needed. The hip (iliac crest), are common donor sites. These procedures are not routinely performed in an operating room and require a hospital stay.
MINOR BONE GRAFT
This could be available by a tissue bank , processed biological bone (Allograft) . In this case the procedure does not require a donor site which is a second remote surgical site.
Special collagen membranes may be utilized that dissolve under the gum to protect the bone graft as well as encourage bone regeneration .This is called guided bone regeneration and guided tissue regeneration.
