This study investigates the biomechanical performance of T-loop designs with helices in orthodontic applications, focusing on their load deflection rate at varying activation levels. The results demonstrate a reduction in the load deflection rate at 1 mm, 2 mm, and 3 mm activations, highlighting the enhanced control and efficiency of force delivery in orthodontic treatments. The incorporation of helices in T-loop designs contributes to improved biomechanical behavior, offering clinicians a more predictable and effective tool
for tooth movement. These findings underscore the potential of T-loop designs with helices to optimize orthodontic mechanics, particularly in cases requiring precise force application. Further research is recommended to explore their clinical implications and long-term performance in diverse treatment scenarios.
