An alveolar distraction is recognized to be a surgery in the preparation of future implant site.
This technique can be used for not only implant treatment, but also for the natural teeth. It is "dentulous distraction" that the osteotomized bone block including teeth can be repositioned based on orthodontic criteria. This technique allows the alignment of ankylosed half-impacted tooth not treatable by orthodontics and can also use the surgical assisted orthodontics for the treatment of anterior open bite.
Dentulous distraction was performed in two patients, a 8 years old girl who had a ankylosed half-impacted maxillary central incisor and a 21 years old lady who had a dento-alveolar deformity with anterior open bite. In both cases, successful repositioning to the ideal teeth position was achieved. Dentulous distraction can be used for surgical assisted orthodontic treatment.
