Abstract

Background:  Frictional forces generated between bracket and arch wire have a significant effect on tooth movement. Conventional ligated brackets incur increased levels of frictional resistance via the elastomeric attachment between bracket and arch wire. Self-ligation eliminates the requirement for an elastomeric attachment and is associated with considerably reduced friction with different arch wires.  Materials and Methods: The first group (Group A) consisted of 10 patients who had undergone treatment with Ormco Damon Q Brackets. The second group (Group B) consisted of 10 patients who had undergone treatment with Conventional Brackets (MBT). The distances from the mesial aspect of the canine bracket to the distal aspect of the first molar bracket were recorded before (T1) and after space closure (T2), and an average rate of space closure per month was calculated.  Results: The overall rate of retraction using Damon Q Group and Conventional MBT Group were similar and there were no significant differences in the amount of anchorage loss. Conclusion: With Ni-Ti coil springs with the wire sequence and bracket prescription used in this study, there was no difference in the rates of space closure and anchorage loss between Damon Q and conventional MBT brackets.
