a Virtual simulation based on cephalometric prediction. Although midline correction was achieved (red line), the contour correction was inadequate (arrows). b The maxillomandibular complex was yawed, maintaining the anterior midline as a hinge, i.e., the posterior part of the complex was rotated toward the direction indicated by the dotted arrow. c More yawed than in (b). In this case, b was selected as the best reposition
