「Case」 A 16-year-old female presented her chief complaint was an impacted upper left canine. Clinical examination showed dental Class II division 2 with deep bite and upper midline deviation. Her both lateral incisors were diagnosed with pulp necrosis and apical periodontitis. Periapical radiography showed the impacted canine was buccally positioned with mesial tilting. Radiolucent lesion was significant larger in size and external root resorption of lateral incisor was noted. Treatment plan was root canal treatment of bilateral lateral incisors combined with surgical exposure and orthodontic traction of the impacted canine. In the final results, successful orthodontic traction of the impacted canine with complete healing of cystic lesion, normal overjet, overbite, canine and molar class I relationship were achieved.
