Abstract
This case report describes the treatment of a 15-year-old girl showing Angle’s Class II Division 1 malocclusion with maxillary prognathism and marked labial inclination of the maxillary anterior teeth, which was characterized by a large overjet, overjet occlusion, and mild crowding in the lower jaw. Our treatment completed without root resorption as a result of the combined use of a wire mechanism and anchors has rarely been reported before. The left and right maxillary first premolars were extracted, a temporary anchorage device (TAD) was used for space closure, and oral hygiene maintenance guidance was provided. The total treatment time was approximately 2 years and 7 months. Ideal overjet and overbite relationships were established, and the facial profile improved substantially. The 2-year follow-up assessment showed a morphologically and functionally stable result. For patients with marked maxillary prognathism, orthodontic treatment using TADs enables simultaneous and efficient maxillary anterior tooth retraction and reduction of overjet. Moreover, this treatment has the potential to shorten the treatment duration and contribute to the long-term stability of excessive overjet correction.Keywords
