Expanding Horizons: A Case Report of Cleft Expansion in the Mixed Dentition Stage.

A nine-year-old boy with a cleft lip and palate had midface retrusion as a result of maxillary complex growth inhibition. He sought treatment for total crossbite with a Class III skeletal pattern. The maxillary expansion widened the maxilla to improve the sagittal and transverse skeletal relationship. In skeletal Class III patients with a repaired cleft lip and palate, maxillary expansion and protraction usually provide effective improvement. The individual growth of the maxilla and mandible is crucial to the success of the orthopedic procedure.
