Abstract
This case report describes a successful orthodontic treatment of a 17-year-old adolescent male patient with unilateral cleft lip and palate on the right side. He showed collapsed posterior segment due to severely constricted maxilla of the affected side, missing of right maxillary lateral incisor, and severe crowding in the both maxillary and mandibular arches. The maxillary arch expansion was performed slowly using quad helix to enable the soft tissue to be lengthened. And then, comprehensive orthodontic treatment with first premolar extraction was proceeded. For the upper left quadrant, the canine was extracted instead of the first premolar to prevent gingival recession. After the orthodontic treatment, the congenital missing maxillary lateral incisor was rehabilitated with crown and bridge. The patient achieved improved facial profile with favorable occlusion, which maintained well until 2.5-year retention.
