Abstract
Superior surgical techniques by oral and maxillofacial surgeons should be required for obtaining stability on patients' prognoses. Furthermore, the coordination between the maxillary and mandibular arch forms should be attained by preoperative orthodontic treatment, that would enable smooth osteotomy.
However, many different factors of each patient would sometimes make the preoperative orthodontic treatment difficult to obtain an ideal relationship between the maxillary and the mandibular arch forms.
In the present study, a patient with a skeletal Class III malocclusion and severe deep overbite was treated by surgical orthodontic treatment. In this case, a prominently narrow mandibular arch and closed occlusion was made to interrupt preoperative orthodontic treatment in order to attain coordinated arch widths between the maxilla and the mandible. Furthermore, we discussed the procedures for rasing vertical dimension, correcting arch form disharmony between the maxilla and the mandible, and obtaining stability on patients' prognoses, as in this case.
