Figure 12.

An adult patient with Class II dysgnathy and deep bite (skeletal). The correction of skeletal Class II and the skeletal deep bite is performed via combined orthodontic surgical treatment. Posterior rotation of the mandible during surgical mandibular advancement caused bite elevation and lengthening of the lower facial height. (A–C) show orthodontic surgical treatment. (D) shows the over-positioning of the pre-treatment (black) and post-treatment (red) radiographs due to the changes in sagittal and vertical dimensions. The surgical rotation of the mandible caused the opening of the mandibular angle, which led to the lengthening of the lower facial height. (E–G) show after orthodontic treatment.
