Non-prosthetic treatment using segmental osteotomy and bone grafting in a patient with cleft lip and palate

This case report aimed to present the course of surgically combined comprehensive orthodontic treatment of a male adult with cleft lip and palate, showing a left alveolar cleft, lateral deviation of the major segment of the maxilla, and palatal transposition of the lateral incisor. Preoperatively, the midline of the upper central incisors was shifted by 7.0 mm to the right, the right lateral incisor showed palatal transposition, and the residual alveolar cleft was 6.5 mm. Segmental Le Fort I osteotomy of the major segment, and simultaneous bone grafting into the extended alveolar bone and former cleft region were performed at 18 years and 4 months of age. Thus, midline correction, alignment of the right lateral incisor, and cleft closure were achieved; no further prosthetic treatment was required
