Three-Year Follow-Up of a Patient With Unilateral Cleft Lip and Palate Treated With Maxillary Protraction and Alveolar Bone Grafting: An Approach Exploring the Potential Power of Growth

Clinically, patients with operated unilateral cleft lip and palate always present with a concave profile, depressed midface, maxillary hypoplasia, narrow upper dental arch, and class III malocclusion. In this clinical report, the authors describe the successful orthodontic treatment of a patient with unilateral cleft lip and palate. A boy, 7 years 11 months of age, with a history of unilateral cleft lip and cleft palate presented with a Class I malocclusion on Skeletal Class III base. A satisfactory occlusion and a favorable lateral profile were achieved after maxillary protraction (face mask) combined with fixed appliance treatment, including alveolar bone grafting surgery. An acceptable occlusion and facial proportion were maintained after a 3-year retention period. These results suggest orthodontic treatment with growth interference is an effective option for a patient with cleft lip and palate.
