Preparation for alveolar bone grafting
Patients with cleft lip and palate often present with alveolar clefts or missing bone in the areas of the gum ridge opening and teeth beside it. Alveolar bone grafting (ABG) aims to provide bone into these areas to allow for healthy permanent tooth eruption.
The need and appropriate timing of alveolar bone grafting is often assessed at age 6. Timing of surgery coincides with eruption of the permanent lateral incisor or canine at ages 7 to 12. These two teeth are the teeth most often adjacent to the gum ridge cleft. Bone is required to maintain these teeth for the long term.
Your surgeon and orthodontist work closely together to coordinate your care. Prior to the ABG, an orthodontic expander and braces may be recommended to provide better outcomes for the graft and dental alignment. The surgeon will then be able to use bone, most often from the hip, to fill the alveolar cleft. Either the orthodontic expander or a retainer will be used on the teeth to hold it in place for a few months while the graft heals. During this time, good oral hygiene is important to improve graft success. X-rays are provided six months after the graft to evaluate its healing.
