Introduction: Extraction is one of the most commonly used orthodontic tools in the treatment of many orthodontic problems such as; relief of anterior crowding, reduction of dento-alveolar protrusion, improving facial esthetics and correction of dental arch mal-relationships by dental camouflage.The first premolar extraction followed by distal canine retraction is considered the most frequently used tactics to solve the previously mentioned orthodontic problems. Aim of this study: The aim of this study was to 1- Compare the rate of canine retraction between self-ligating brackets resembled by low friction device (clear snap) and conventional brackets. 2- Evaluate the position of the canines in the two bracket systems regarding the torque, tip and rotation using cone beam computed tomography in a split mouth technique. Materials and methods: This study was carried out to compare, the rate of canine retraction between self-ligating brackets resembled by low friction ligture (clear snap) and conventional brackets ligated by st. st. ligature. Also to three dimensionally evaluate the position of the canines after its retraction in the two bracket systems regarding the torque, tip and rotation using cone beam computed tomography. After extraction of maxillary first premolars, levelling and alignment were established. Using Ni-Ti. pull coil sprig, canines retraction on both sides were started and the rate of canine movement was measured every month until at least one of them do contact with the second premolar. CBCT images were taken before and after canine retraction to evaluate the three-dimensional changes in the positions of maxillary canines. Results: 1.The canine’s bonded with conventional bracket where the arch wires were ligated with clear snap device showed higher rate of canine retraction than those conventional brackets ligated with st.st. ligature wire. The former showed mean monthly rate 1.28 mm/month while the later showed only 1.08 mm/month. 2. Insignificant increased in the mean change values were established for canine’s brackets attached with clear snap device than those ligated by st. st. ligature wire as regard to torque, tip and rotation.Conclusion: Using self-ligating bracket system might not add advantage as regard to treatment duration as the shorter duration gained from canine retraction with self-ligating bracket system could be consumed by the more time needed to correct the combined increase in tip and rotation.
