Outcome Measures

Primary Outcomes (1)

Rate of canine retraction
The rate of canine retraction will be calculated by "the amount of canine retraction (in millimeters) divided by the time interval". The amount of canine retraction will be assessed by measuring the distance from the canine cusp tip to the mesio-buccal (MB) cusp tip of the 1st molar with a calibrated caliper at the time of placement of loops and at every month by a single calibrated clinician. The duration will be measured as a time interval and each time interval will be 4 weeks.
From enrollment till end of treatment at 4 months

Secondary Outcomes (3)

Change in canine angulation at start of canine retraction and at the end of canine retraction
From enrollment till end of treatment at 4 months
Change in anchorage loss before and after completion of canine retraction
From enrollment till end of treatment at 4 months
Change in molar rotation at before and after completion of canine reatraction
From enrollment till end of treatment at 4 months
