Abstract

This case report describes a successful orthodontic treatment in an Angle Class II division 1 malocclusion with severe space deficiency by temporary anchorage device (TAD) in a 15-year-old male patient. The skeletal analysis showed mandibular retrognathism and slightly hyperdivergent growth pattern. The treatment plan included four first premolars extractions combined with TAD application which used for anteroposterior and vertical anchorage control. The orthodontic treatment was to achieve the effect of counter-clockwise rotation of mandible for the patient who still has remaining growth. After 23 months of orthodontic treatment, Angle Class I molar relationship was achieved. The patient was satisfied with his facial appearance.
