Abstract
This case report describes the use of Improved Super-elastic Ti-Ni alloy wire (ISW), developed by Tokyo Medical and Dental University, in managing a skeletal Class III malocclusion with anterior crossbite and a missing lower molar. A 26-year-old female presented with a chief complaint of poor dental alignment. Clinical and radiographic evaluation revealed Angle Class III malocclusion, anterior crossbite, a missing mandibular first molar (36), and a centric occlusion–centric relation (CO–CR) functional shift, consistent with a skeletal Class III pattern. Treatment involved the use of ISW for leveling and alignment of both arches and correction of the anterior crossbite, while maintaining space in the lower left quadrant for future prosthetic rehabilitation. Intermaxillary elastics were applied to enhance occlusal interdigitation. Treatment was completed over 22 months, achieving a stable occlusion and improved facial and dental aesthetics.
