Bone Grafting

Major and Minor Bone Grafting For Dental Implant Placement

Over a period of time, the jawbone associated with missing teeth atrophies is reabsorbed. 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.

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 esthetic appearance. Dr. Koul frequently carries out bone grafting of tooth extraction sockets to insure that the bone will regenerate for eventual implant placement. This is also called site preservation, meaning preserving the site for eventual implant placement. The tooth is carefully extracted or surgically removed, the socket cleaned out of infection, grafted with bone bank bone and covered with a slowly resorbable membrane. Non-resorbable sutures are placed, which are kept in three or four weeks. Six months later a dental implant can be placed.

Major Bone Grafting

Bone grafting can repair potential 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. 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 traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone or bone bank bone.
