Abstrakt: Background: Orthodontic management of an ectopically erupted canine requires substantial amount of bodily movement which is difficult to perform and often results in root resorption.
Case Presentation: A 9 year old girl presented with Class I malocclusion with crowding and ectopically positioned upper left canine (23). Treatment involved extraction of all first premolars. The alignment of the upper left canine was achieved by the modified 2 by 1 appliance.
Conclusion: The design of this modified 2 by 1 appliance allows individualized bodily tooth movement of canine, it provides light and continuous force for physiological orthodontic movement with minimal root resorption.
