Over a period of time, the jawbone associated with missing teeth atrophies or shrinks. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants.
Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place dental implants of proper length and width, it also gives us a chance to restore functionality and aesthetic appearance.
Bone grafting can increase the amount of bone available for a dental implant. The bone is either obtained from a tissue bank or your own bone is taken from the jaw to be used as the bone graft. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special barriers 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.
