Down syndrome (DS) is a genetic disease known as trisomy 21. Congenital cardiac anomalies are present in about 40% of DS patients. Dental anomalies are also common among DS patients. In DS patients, canine impaction is 10 times more frequent and transposition of maxillary canine and first premolar is 50 times more common than in general population. A female DS patient with congenital heart disease was diagnosed as having a transposed impacted maxillary canine. Sectional fixed appliance with Nance holding arch was used for the orthodontic treatment. After space was regained for the eruption of the canine, orthodontic button was attached using flap operation with closed technique. Traction and alignment of the tooth followed. To prevent endocarditis, prophylactic antibiotics were prescribed for the recommended dental procedures. Total treatment time was 25 months and no complication was found.
