A young male (14 years old) came to our clinic with a chief complaint of maxillary protrusion and not being able to chew food well with his right posterior teeth. Clinical examination revealed Class II division 1 malocclusion with unilateral scissors bite on the right side. With successful molar upright on the right lower arch by bracket upside-down, adding crown buccal torque on the archwire and ISW(Improved Super-elastic Ti-Ni alloy wire, developed by Tokyo Medical and Dental University) Expansion Arch technique, scissors bite was corrected quickly. Treatment was completed within 15 months and a desirable occlusion after the active treatment was achieved.
