Management of alveolar cleft bone grafting--state of the art.
Bone grafting of the alveolus is an essential step in the reconstruction of the orofacial cleft deformity. Secondary grafting with iliac marrow consistently produces trabecular bone to unify the maxilla and provide odontogenic support. It requires preoperative maxillary alignment, well designed mucoperiosteal flaps, and good oral hygiene to be optimally successful. Its high success rate currently makes it the preferred approach at most centers. Primary grafting with rib results in a unified maxilla, eliminates the oronasal fistula, and does not adversely affect midfacial growth. It assists in preventing maxillary segmental collapse, particularly in the bilateral cleft patient. Whether it can produce enough alveolar bone to support long-term odontogenic needs awaits further clinical documentation in the limited numbers of centers that routinely perform this procedure.
