Camouflage Orthodontic Treatment of Skeletal Class II Malocclusion with Missing Mandibular Incisors Using Improved Superelastic Ti–Ni Alloy Wire

This article presents a camouflage orthodontic treatment utilizing the improved superelastic Ti-Ni alloy wire (ISW) to address a case of skeletal Class II malocclusion with two missing mandibular incisors. A 28-year-old female patient with a chief complaint of poor dental alignment sought orthodontic evaluation. Clinical examination revealed a Class III molar relationship, mild crowding, and lingually positioning of tooth 35. Radiographic analysis confirmed a skeletal Class II pattern. The treatment plan included the application of an ISW curve over the maxillary arch to control anterior tooth inclination. Canine distal drive and anterior retraction were performed following the extraction of bilateral upper first premolars. Additionally, the ISW inside-out technique was employed to expand the mandibular arch, facilitating the alignment of the lingually positioned tooth 35 into normal occlusion. By the end of the treatment, a pleasant improvement in the patient’s profile was observed, along with the establishment of a stable occlusion, preserving the two remaining mandibular incisors.
