Abstract

A 20-year-old female presented with concerns about poor dental alignment and a tendency to bite on her lip easily. Clinical examination revealed a concave and brachy facial profile, accompanied by a deep overbite and a moderate overjet. Radiographic examination showed skeletal Class III with a low mandibular plane angle. Correction of the deep bite was achieved by using the Improved Super-elastic Ti-Ni alloy Wire (ISW) and Intermaxillary elastics (IMEs). To correct the moderate overjet, interproximal reduction (IPR), the Multi-bend Edgewise Archwire (MEAW) technique, and arch lengthening of the lower arch were applied. The active treatment duration took approximately 54 months, resulting in significant improvements in appearance and dentition alignment.
