Abstract
Cleft lip and palate(CLP) patients usually have midface deficiency and Class III malocclusion. Distraction osteogenesis (DO) has been used recently to correct the maxillary hypoplasia with stable and predictable result. Both external and internal devices that permit midface distraction are available, This case report describes intraoral DO for correction of the midface deficiency in a adult CLP patient with relapse following orthognathic surgery. The purpose of this report is to present advantages of the intraoral DO for the treatment of CLP, The relative and potential clinical indications, treatment planning, patient preparation, and possible vector control for DO are discussed
