Material and methods: Seventy-two maxillary right stainless steel canine brackets, with slot size 0.022x0.028-inch, were used. The brackets were equally divided into three groups; Group {u2160} for the fx SWLF brackets, group {u2161} for the Damon 3 MX (self-ligated) brackets, while group {u2162} was for Mini 2000 conventional brackets UR - http://172.23.153.220/th.pdf ER -
