The Elimination of Dental Crowding and Development of a Proper Dental Arch by Maxillary Anterior Segmental Distraction Osteogenesis for a Patient With UCLP.

OBJECTIVE: This report describes the case of a male patient with a complete unilateral cleft lip and palate who presented with midface deficiency and an anteroposteriorly constricted maxilla. DESIGN: Case report Interventions: Correction involved anterior distraction of the segmented maxilla. RESULTS: The present case demonstrates that elongation of the maxilla with anterior distraction is an effective way to develop a proper dental arch, correct anterior and posterior crowding, and improve a midface deficiency.
