Major & Minor Bone Grafting
Over a period of time, the jawbone associated with missing teeth and lack of use will reabsorb. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. It used to be that most patients with jawbone degeneration were not candidates for placement of dental implants.
With today’s technology however, we have the ability to grow bone where needed. This not only aids an implant placement of proper length and width, but also allows for the restoration of dental functionality and aesthetic appearance.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure, brought on by previous extractions, gum disease or injury. The bone is either obtained from a tissue bank or other sites in the patient’s mouth. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. For additional protection of the bone graft, guided bone regeneration may be encouraged. In this process, special membranes are utilized that dissolve under the gum and encourage bone 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 birth defects. Large defects are repaired using the patient’s own bone. This bone may be harvested from a number of different sites, depending on the size of the defect.
