 note = {application/pdf, Summary This case was a 10–years and 10–month–old girl who visited the hospital with a complaint of opposite anterior bite. Facial findings showed no anterior asymmetry, but lateral features showed a concave type. The molar relationship was Angle Class III on both sides,and the left side showed a more prominent class III relationship. Anterior cross bite and labial inclination of both upper and lower side anterior teeth were observed. The diagnosis was a case of skeletal mandibular protrusion with functional factors. It was decided to use a chin–cap type anterior traction device of the upper jaw that can promote the growth of the upper jaw and suppress the growth of the lower jaw. In the phase of adult treatment, it was decided to extract the maxillary right first premolar, the maxillary left second premolar,and the mandibular bilateral first premolar to establish Angle Class I. At the end of the dynamic treatment, the molar relationship showed Angle Class I on both the left and right sides, and a tight and stable cusp fitting was maintained. Although ANB did not change on the lateral cephalogram, labial inclination was observed on both upper and lower anterior teeth. The dynamic treatment period was 2 years and 11 months, and the end age was 18 years and 1 month. No problem was observed in the occlusal state 4 years after the device was removed, but it will be carefully observed in the future.},
