Description
The patient was a 18-year 6-month female, and her chief complaint was mandibular protrusion with occlusal disturbance. Her facial profile was concave with a naso-maxillary hypoplasia and long anterior facial height, and the ratio of the upper, middle and lower facial height was 1:1.1:1.3. The upper right first molar and both the upper second premolars were missing and total crossbite was present. For the correction of skeletal mandibular protrusion with total crossbite, two-jaw surgery was required. After starting distal movement of the upper right second molar, multi-bracket appliances were placed on the upper and lower dentitions. After 1-year and 3-month of pre-operative orthodontic treatment, she received a surgery of LeFort I midfacial advancement for the maxillary and the bilateral intaoral vertical ramus osteotomy was also performed for the mandible. After 1-year and 6-month of post-operative treatment, an acceptable and stable occlusion was achieved and the multibracket appliances were removed. Overall facial balance was improved, and the ratio of facial height was changed into 1:1:1.1. At 3-year and 10-month after surgery, the acceptable occlusion was maintained.
