Maxillary Canine Retraction Using Stainless Steel and Titanium-molybdenum Alloy Wires in TAD-supported Segmental Mechanics
Sponsor: Tanzila Rafique
Summary
The goal of this randomized clinical study is to compare the effectiveness of stainless steel (SS) and titanium-molybdenum alloy (TMA) wires for maxillary canine retraction using TAD-supported segmental mechanics. The main question it aims to answer is: Which wire material, stainless steel or titanium-molybdenum alloy, provides better outcomes in maxillary canine retraction when used with TAD-supported segmental mechanics? Researchers will compare SS reverse-closing loops with TMA reverse-closing loops to evaluate differences in the rate of canine retraction and canine angulation changes during orthodontic space closure. Participants will: * Receive mini-implants/TADs on both sides of the maxillary arch. * Receive a stainless steel reverse-closing loop on one side and a TMA reverse-closing loop on the contralateral side. * Receive the same standardized force of 150 g on both sides. * Visit the clinic every 4 weeks for a total duration of 4 months. * Undergo OPG radiographs before retraction and after the 4-month study period to assess canine angulation.

Interventions
A titanium-molybdenum alloy reverse-closing loop
A titanium-molybdenum alloy reverse-closing loop will be placed on one side of the maxillary arch, and a stainless steel reverse-closing loop will be placed on the contralateral side of the maxillary arch and activated with a 150 g force to retract the canine.
A stainless steel reverse closing loop
A titanium-molybdenum alloy reverse-closing loop will be placed on one side of the maxillary arch, and a stainless steel reverse-closing loop will be placed on the contralateral side of the maxillary arch and activated with the same 150 g force for canine retraction.
