Objective: This study was to compare the rate of canine retraction with two commercially
available straight wire brackets. Materials and methods: A sample of 10 patients
with an age range from 15 to 18years, requiring orthodontic treatment. The study was designed clinically (split mouth technique) in the same patient right side bonded by Ormco Roth orthodontic brackets while in the left side were bonded byIMD Roth orthodontic brackets . Canine retraction was measured four times every 28 day till complete
retraction of canine occurred. Results: the rate of canine retraction was non significantly
different from right and left side, also monthly, weekly and daily rate of canine retraction was non significantly different in the right and left side. Conclusion: The rate of Canine retraction using (IMD brackets is insignificantly different from (Ormco)brackets, both of them have the same rate, during the first ,second, third and fourth interval no significant difference on the rate of canine retraction between the 2 groups
