The Effectiveness of Double-slot Brackets Versus Single-slot Brackets on the Rate of Canine Retraction
Sponsor: Cairo University
Summary
The aim of this Randomized clinical trial is to compare the efficacy of the double slot brackets compared to single slot-brackets in producing a controlled rate of upper canine retraction into premolar extraction space. patients will be randomly divided into one of the two groups, CBCT (cone beam computed tomography) and dental models will be taken for each patient Pre-retraction and following the study completion. The rate of retraction will be evaluated for both groups as well as Amount of canine root movement and molar anchorage loss will be also assessed.

Double-slot brackets
Miniscrews will be inserted in the buccal alveolar bone between first and second molars bilaterally and ligated to second premolar. Canine Retraction using Nickel titanium closed-coil springs delivering a force of 150 gram, extending the spring between the canine and first molar hooks. retraction on double 0.016'' Stainless steel round wires in both slots of the double slot brackets. Re-activation of the coil spring will be done in the follow up visits to maintain a constant force through the study.
Single-slot brackets
Miniscrews will be inserted in the buccal alveolar bone between first and second molars bilaterally and ligated to second premolar. Canine Retraction using Nickel titanium closed-coil springs delivering a force of 150 gram, extending the spring between the canine and first molar hooks. retraction on single 0.017x0.022'' Stainless steel wire. Re-activation of the coil spring will be done in the follow up visits to maintain a constant force through the study.
