Fig. 5. Pretreatment, posttreatment lateral cephalometric radiographs (A) and superimposition analysis (B). (A) Pretreatment (1), posttreatment (2) radiographs and cephalometric analysis (3). (B) Superimposition of pretreatment and posttreatment. B-1, Superimposition of the maxilla and mandible based on the cranial base (Nasion-Basion line). B-2, Superimposition of the maxilla based on palatal plane (ANS-PNS). B-3, Superimposition of the mandible based on Xi-Pm line (Xi, the point placed in the center of the mandibular ascending ramus; Pm, point where curvature of the anterior contour of the symphysis changes from concave to convex). During orthodontic treatment, the vertical position of the mandibular posterior teeth was maintained and the mandibular anterior teeth were intruded and labioversion. However, the maxillary molar was mildly extruded during the leveling process, and a slight clockwise rotation of the mandible was observed (gray line: pretreatment, red line: posttreatment).
*, **, ***, indicates that the value is beyond one, two or three times of the standard deviation.
