Treatment of Class II open bite complicated by an ankylosed maxillary central incisor.

Ankylosed teeth in growing patients cause troublesome dentoalveolar problems and require special therapeutic care for accomplishing long-term esthetic and functional results. The various treatment modalities for ankylosed teeth include reconstruction after extraction, surgical extrusive luxation, individual segmental osteotomy or corticotomy, and alveolar distraction osteogenesis. This report describes a case of a 13-year-old boy with anterior open bite complicated by an ankylosed maxillary central incisor that was managed by corticotomy-facilitated orthodontic treatment.
