Clinical, stone-model, and radiographic photographs of a 19-year-old female patient who received orthodontic treatment by the aids of temporary anchorage devices and bilateral mandibular sagittal split osteotomies because of facial asymmetry, canted occlusal planes, and posterior bite collapse. (A) The pre-treatment extraoral photograph showing severe facial asymmetry with chin deviation to the right side. (B and C) The pre-treatment intraoral closed- (B) and open-mouth (C) views revealing the maxillary and mandibular occlusal planes canted toward the opposite directions. (D and E) Intraoral photograph from the buccal aspect (D) and the closed view of initial stone model from the lingual aspect (E) exhibiting the left buccal segment with complete buccal crossbite and vertical overgrowth of dentitions. (F, G, and H) Pre-treatment panoramic (F), lateral cephalometric (G), and posterior anterior cephalometric radiographs (H) of the patient. (I and J) Twenty-two months after the treatment, pre-surgical records showed that initially canted maxillary occlusal plane was corrected. (K, L, M, N, O, P, Q, R, and S) Post-treatment records demonstrated the significantly satisfactory clinical outcomes. (T, U, V, and W) The successful clinical outcomes persisted 10 years after the treatment.
