Non-surgical and Non-extraction Orthodontic Treatment of an Excess Reverse Bite with Anterior Open Bite

Abstract

This 13-year-old female had a severe Angle’s Class III malocclusion with an excessive negative overjet 7 mm, anterior open bite 2 mm, a prognathic chin and a concave lateral profile. But this patient and her parents refused orthognathic surgery. Finally, she was treated with a non-surgical and non-extraction approach. The treatment plan consisted of total distalization of mandibular dentition with bilateral temporary anchorage device (TAD) and maxillary incisor extrusion with vertical elastics. The active treatment period was 34 months. Normal overbite, overjet, and acceptable profile were achieved.
