Abstract
Purpose: This study was carried out to assess the effect of different types of ligatures on the rate of canine retraction. Materials and Methods: 14 participants requiring extraction of upper first premolars, were randomly assigned into 2 groups;  group 1 had passive self-ligating bracket on the upper right canine, figure of 8 module ligature on the upper left canine and group 2  also had  self-ligating bracket on the upper right canine, and slide-low friction elastic module on the left side. Canines retraction were done under 150 gm of force using a 9 mm nickel-titanium closed-coil spring .Alginate impression was taken at the onset of canine retraction(T0), and every month (T1T4). Study casts were fabricated and then scanned with a 3D scanner. Results: The statistical analysis showed no statistically significant difference in the rate of canine retraction between the 2 groups, and between the control and intervention sides within each group. Conclusion: The difference in rate of upper canine retraction between self- ligation brackets, figure of 8 elastic module and slide –low friction ligature was not statistically significant.
