Abstract

This 16-year-old female presents with Class II Division 1 subdivision right malocclusion, complicated by gummy smile, large mandibular plane angle and the mandibular right first molar missing. Treatment consisted of 4 temporary anchorage devices (TADs) application and extraction of bilateral maxillary first premolars and the mandibular left first premolar. Bimaxillary anterior and posterior teeth were intruded by miniscrews for counterclockwise rotation of the mandible. A very favorable result was achieved due to reduction of gingival display and the mandibular plane angle was decreased successfully.
