Evaluation Of Anchorage Control Using Arch Wire Stopper Versus Mini-Screws

The study begins with patient selection according to inclusion and exclusion criteria, followed by treatment planning, and then bonding of orthodontic brackets of the upper and lower arches, including the second maxillary molars. After leveling and alignment for all participants, the extraction of the maxillary first premolars will be performed. • In the "Intervention Group" Canine retraction will be performed on 0.017×0.025 ss archwire with an archwire stopper mesial to the upper first molar. Afterwards, anterior segment retraction will be done using T-loop on 0.017x0.025 TMA archwire • In the "Comparator Group" Canine retraction on 0.017×0.025 ss archwire with the upper first molars indirectly anchored to inter-radicular mini screws Afterwards, anterior segment retraction will be done using T-loop on 0.017x0.025 TMA archwire Lastly, the anchorage control in both groups and the secondary outcomes will be assessed using the obtained digital models and lateral cephalometric radiographs.
