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 that 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 unerupted 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 (premaxilla), if a bilateral cleft is present
Bone grafting is a useful procedure and is most successful in patients under 10 years of age and as early as 5 to 6 years of age, as the front incisor teeth are erupting. The overall erupting varies from child to child, but usually is completed between the ages of 10 and 12. If the bone graft is placed after the permanent teeth have erupted, it will be too late to achieve goal number one above, although it may be useful toward achieving the remaining three goals.
Older patients may benefit from a bone graft, but have less chance of total success. If the patient is a smoker, has a systemic disease such as diabetes, or has poor oral hygiene, the risk that the graft may fail increases even more.
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:
- Moving adjacent teeth into the bone graft
- Prosthetic replacement (dental bridge)
- Dental metallic bone implants
The best bone grafting options are best decided by dental specialists on a cleft palate team who can determine what the benefits and risks are for individual patients.
