Arms & Interventions

Group1: Elastomeric chains will be used on the right side, and NiTi closed-coil springs will be use

Experimental

Intervention: Twenty-Two adult Patients who indicated for bilateral maxillary first premolar extraction will be randomly assigned into two equal group. (Procedure)

Group1: Elastomeric chains will be used on the right side, and NiTi closed-coil springs will be use

Experimental

Intervention: Canin retraction with NiTi Closed-Coil Springs and elastomeric chains (Procedure)

Group2: NiTi closed-coil springs will be used on the right side, Elastomeric chains will be used on

Experimental

Intervention: Canin retraction with NiTi Closed-Coil Springs and elastomeric chains (Procedure)

Outcomes

Primary Outcomes

Change in Apical Root Length After Canine Retraction

Time Frame: 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

Time Frame: 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.

Secondary Outcomes

  • 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)
