Bone Grafting

What is bone grafting?

Over a period of time, the jaw bone formerly supporting teeth now missing is resorbed (atrophy).  This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.

In many cases today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and aesthetic appearance.

What is 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 and 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 periodontal disease, infection, traumatic injuries, tumor surgery, or congenital defects. Large defects usually are repaired using the patient’s own bone to some extent. This bone is harvested from a number of different sites depending on the size of the defect, but we try to limit surgical procedures to other areas of the mouth.
