Bone Grafting

Bone Grafting

Major and Minor Bone Grafting

Damage to the jawbone can be caused in areas where there are missing teeth. The jawbone can deteriorate and change the facial structure and make it unsuitable for a dental implant. Today’s technology can repair the inadequate bone in preparation for dental implants, restoring functionality and esthetic appearance.

Major bone grafts repair implant sites where a previous extraction has taken place, one had gum diseases, or injury has caused deterioration of the bone. The bone is obtained from a tissue bank taken from the jaw or larger bones like the hip. To replace bone in the upper jaw, sinus bone grafts are performed. Special membranes are sometimes used to dissolve under the gum to protect the bone graft and encourage regeneration.

Minor bone grafts are used to repair defects in the jaw. These defects are usually caused by traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. If the jaw has a significant amount of deterioration, areas of bone harvest will be the skull, hip, or lateral knee.

Ridge Expansion

A patient will need a ridge expansion when the ridge is reabsorbed and need an increase in height or width. The bone graft will restore lost bone dimension when the ridge is too thin to place an implant. The ridge of the jaw is expanded by mechanical means in this procedure. The bone graft will need to be placed and mature for a few months before the implant can be placed.
