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 which is unsuitable for the placement of dental implants and may also casue shifting of remaining teeth and changes to facial structure. Most patients, in these situations, are not candidates for dental implants unless bone grafting is done first.

Fortunately, today we have the ability to rebuild bone where it is needed in most cases. 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.

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 typically and may also be taken from small areas from your jaws. 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.
