Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often results in a condition in which there is poor bone quality and/or quantity suitable for the 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 aesthetic appearance.
Bone grafting can repair future 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 encouraging bone regeneration. This is called guided bone regeneration or guided tissue regeneration.
