Alveolar bone grafting (ABG) is an essential part of the surgical management of cleft lip and palate patients. This procedure could obliterate oronasal fistula, stabilize dental arch, offer bone matrix for adjacent teeth eruption. Moreover, by obliterating oronasal fistula, we stop the chronic irritation of nasal mucosa by oral content. Hence, the symptoms of rhinorrhea or nasal obstruction could be improved. This dental arch defect could predispose further dental arch medial collapse. Without alveolar bone grafting the dental arch is not stable, dental movement during orthodontic treatment is limited and dental arch expansion is not possible. Previous to operation, the patient suffered from dental crowding and dental inclination toward to the cleft. This produces a difficult dental hygiene and predispose to dental caries and gingivitis. Pre-operative orthodontics treatment is advised in many centers. By aligned the teeth previous to surgery, with a better dental hygiene, we purpose that the infection rate will be reduced and success rate will be better. The Purpose of this study is to determine whether pre-operative orthopedic treatment will affect secondary alveolar bone grafting outcome and to assess the nasal change after alveolar bone graft.
