Improvement of Alveolar Bone Morphology by Alignment of Microdontia in the Unilateral Cleft Lip and Alveolus

This case report describes a successful orthodontic treatment with orthognathic surgery of a 17-year-old girl with skeletal Class III and unilateral cleft lip and alveolus on left side. The treatment included extraction of the maxillary premolars and asymmetric mandibular setback surgery. To induce regeneration of buccal alveolar bone on upper left lateral incisor, the palatal positioned left lateral incisor was aligned. After orthodontic treatment with orthognathic surgery, the patient had an improved facial profile, improved alveolar bone appearance on the cleft alveolus area, and favorable occlusion.
