Summary

The study aims to compare the anchorage control using arch wire stopper versus mini-screws in post-pubertal patients with maxillary dentoalveolar protrusion

Detailed description

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.

Conditions

• Orthodontic Appliance Complication

Interventions

Type	Name	Description
DEVICE	archwire stopper mesial to the maxillary first molar group	canine retraction after the extraction of the maxillary first premolars with archwire stoppers is mesial to the maxillary first molars.
DEVICE	inter-radicular mini-screw	canine retraction after the extraction of the maxillary first premolars, with the maxillary first molars indirectly anchored to the inter-radicular mini-screw.
