Bone Grafts
A Bone graft transplants bone tissue. Surgeons use bone grafts to repair and rebuild diseased bones in your hips, knees, spine, and sometimes other bones and joints. Grafts can also repair bone loss caused by some types of fractures or cancers. Once your body accepts the bone graft, it provides a framework for growth of new, living bone. If the transplanted bone comes from another person, it is called an allograft. Most allograft bone comes from donors who have died. Tissue banks screen these donors and disinfect and test the donated bone to make sure it is safe to use. If the transplanted bone comes from another part of your own body, it is called an auto graft. Auto graft bone often comes from your ribs, hips or a leg.
Once the Bone graft has been placed, there are three options that may be considered to replace any missing teeth in the area of the graft. These are:
1) Moving adjacent teeth into the bone graft
2) Prosthetic replacement (dental bridge) or
3) Dental metallic bone implants. The best option for an individual patient is best decided by the dental specialists on the cleft palate team.
Bone Grafting the Cleft Maxilla
Bone grafting in the dental ridge of the upper jaw (maxilla) is now standard, reliable treatment for patients with facial clefts. Bone grafting is an operation which involves taking a small amount of bone from one place (usually the hip, head, ribs, or leg) and placing it in the area of the cleft near the teeth.
The procedure is employed to accomplish the following four goals:-
• To provide support for erupted teeth and teeth next to the cleft.
• To provide support for the lip and nose and to improve symmetry.
• To form a continuous upper gum (alveolar) ridge, creating a more natural appearance and stability to the ridge.
• To improve the stability of the front part of the roof of the mouth, if a bilateral cleft is present.
