- This case report describes the orthodontic treatment of a 31-year-old woman who had a Class II molar relationship, anterior crowding, deep overbite, maxillary dental midline deviation, vertical maxillary asymmetry, and a hyperdivergent facial pattern. The maxillary right first premolar and the left second premolar were extracted asymmetrically to correct the anterior crowding and the maxillary dental midline deviation. The maxillary molars were intruded with a midpalatal miniscrew, which helped to correct the vertical molar asymmetry and close the mandibular plane. The palatal miniscrew in the maxillary tuberosity was also used to provide anchorage reinforcement for retraction of the anterior teeth. After orthodontic treatment, dental and facial esthetics were greatly improved by treatment of anterior crowding and deep overbite, correction of the dental and skeletal asymmetry, and closure of the mandibular plane. At the 3-year follow-up, most of the treatment results had been maintained
