结局指标
主要结局
Change in Apical Root Length After Canine Retraction
时间窗: Baseline (prior to canine retraction) and 6 months after retraction
Measurement of apical root length (in millimeters) using CBCT images at T1 and T2 to assess root resorption on both retraction methods.
Change in Alveolar Bone Thickness After Canine Retraction
时间窗: Baseline (prior to canine retraction) and 6 months after retraction
Quantitative measurement of alveolar bone thickness (in millimeters) using CBCT images taken at baseline (T1) and post-treatment (T2) in both NiTi closed-coil spring and elastomeric chain sides.
次要结局
- Change in Probing Depth(Baseline and 6 months post-treatment)
- Change in Plaque Index(Baseline and 6 months post-treatment)
- Change in Bleeding Index(Baseline and 6 months post-treatment)
