A 19-year-old female came to our department with the chief complaint of facial asymmetry. Clinical examination showed skeletal class III relationship with mandibular prognathism, large reverse overjet, lower right mild crowding, and left hemimandibular elongation. After a thorough discussion with the patient, she accepted the proposal of orthognathic surgery and mandibular setback by bilateral sagittal split osteotomy (BSSRO), and therefore, tooth extraction was performed for 18, 28, 38, and 48 before the surgery. An improved superelastic Ti-Ni alloy wire (ISW wire), developed by Tokyo Medical and Dental University, was then used to facilitate the correction of lower crowding. Involved mechanism included intermaxillary elastics for a better interdigitation and jaw relationships. Adequate overbite and overjet were achieved after treatment completion.

Keywords: Improved superelastic Ni-Ti alloy wire, Orthognathic surgery-first approach, Skeletal class III.
