A research on Canine movement by using sliding approach with or  without hook

Abstract

Canine retraction was done for 19 patients. Movement , Tipping and rotation of canine and molar movements was done by two approaches of sliding hook and sliding mechanics using 16% wire and 18% twin edgewise brackets and were compared. 350 g force via elastic chin was applied and measurements were done both intra- and extraorally. There was not any significant statistical difference between canine and molar movements in both approaches. Canine Tipping and rotation in two approaches showed significant difference. In fact, both were lower in sliding hook approach than sliding mechanics. As lower tipping results were obtained in sliding hook approach, it is suggested to apply this method to bodily retract canine.
