Face mask therapy and conventional orthodontic treatment for anterior crossbite with cleft lip and palate: a case report.

Objective: To demonstrate a conventional orthodontic approach to anterior crossbite with unilateral cleft lip and palate.

Methods: Initially, maxillary expansion and face mask therapy was provided to widen the maxilla and improve the sagittal skeletal relation. Bone grafting to the maxillary left alveolar cleft then was performed, prior to treatment with a multibracket appliance. A multibracket appliance and intermaxillary elastics were used to align the dentition and establish a Class I relationship.

Conclusions: The combined orthodontic treatment of maxillary expansion, face mask therapy, bone grafting, and tooth alignment with a multibracket appliance resulted in a stable occlusion. The mandibular growth appeared after face mask therapy in adolescence; however, positive overjet and overbite were maintained throughout the retention phase.
