Brief Summary
Various malocclusions require the extraction of the first premolars and retraction of the canines with the need for maximum anchorage. If the canines are pulled into the extraction space using the molar teeth for support, unwanted tooth movement occurs. This study aims to evaluate the effect of temporary anchorage devices and power arms, which are auxiliary orthodontic appliances in reducing undesirable tooth movements.

Outcome Measures
Primary Outcomes (2)
Canine retraction
Amount of canine movement in millimeters measured on digital models. . The change in the vertical distance from the canine cusp tip to a line connecting the medial points of the third palatal rugae
Baseline to 6 months
Molar mesial drift
Amount of molar movement in millimeters measured on digital models. The change in the vertical distance from the mesiobuccal cusp tip to a line connecting the medial points of the third palatal rugae
Baseline to 6 months
Secondary Outcomes (2)
Canine tipping
Baseline to 6 months
molar rotation
Baseline to 6 months
Study Arms (1)
Canine retraction
EXPERIMENTALThe canines will be retracted by extending short silver elastomeric chains between the power arms in the canine brackets and the TADs. The applied force will be checked and adjusted to 150 g.
Interventions
Canine retraction using elastomeric chains activated every 4 weeks, using power arms to direct force through the center of resistance and TADs for direct anchorage.
