Abstract

Orthodontic tooth movement is greatly influenced by the characteristics of the applied force. And the characteristics of the applied force depend on the orthodontic appliance used.
Crowding of dental arch often required extraction of 1st premolar to resolve the arch-length to tooth material discrepancy. Obviously, the creation of space in the dental arch through extraction therapy requires some mechanism to consolidate this space to achieve the desired treatment objectives.
Orthodontic space closure has always been a challenge for the orthodontist. With the preadjusted appliance, sliding mechanics is the most preferred method of closing extraction spaces. So this is a comparative clinical study between power chain and active tie-back to compare the canine movement in maxillary arch over the 4 month of continuous retraction using implant as a reference point because implant provide stable reference points for serial superimposition. And 45* oblique cephalometric radiograph for evaluate changes in right and left side separately.

Keywords: Implant, Stable reference point, Superimposition, Power-chain.
