Distraction osteogenesis (DO) has become a mainstream surgical technique for patients with jaw deformities. This case report describes the surgical orthodontic treatment of maxillary hypoplasia in two patients of 14-19 years with cleft lip and palate. They were treated with anterior maxillary DO using rigid intraoral distractor device. Distraction was started after the initial latency period with activation of 0.8 mm/day until positive overjet was gained. Cephalometric analysis was performed twice for evaluation: Before surgery (Pre-Rx) and after distraction (Post-Rx). Both the distractions completed smoothly and maxilla was distracted efficiently. Maxillary prominence increased in both the patients with a positive overjet after distraction. DO provided an effective way to correct maxillary hypoplasia secondary to cleft lip and palate.

A 14-year-old female presented with ectopically erupted upper and lower canines and Class I molar relation. First premolar extraction was planned to correct ectopic position of canines. Segmental titanium molybdenum alloy T-loop was used to retract the canines into an ideal position in the upper arch, and Mulligan's bypass arch was used in the lower arch. Post-treatment results showed a correction of ectopically erupted canines, bilateral Class I molar relation maintained, and inclination of incisors improved. At the end of treatment, the patient showed pleased smile with improved smile arc.
