An 18.7-year-old female patient with an anterior open bite and an ankylosed left maxillary central incisor was referred from a private orthodontic clinic. Canine relationships were Class II and molar relationships were Class I. The open bite was closed with the multiloop edgewise archwire and up-and-down elastics. The maxillary left central incisor was extruded by dentoalveolar distraction assisted with mini-implants. Active treatment took 2 years and 1 month, and the treatment result remained stable 14 months after debonding.
