The goal of this split-mouth randomized clinical trial is to evaluate the effectiveness of corticotomy on maxillary canine retraction rate compared to conventional orthodontic techniques. Each participant acts as their own control. After bilateral maxillary first premolar extractions, one quadrant is randomly assigned to receive corticotomy before retraction, while the contralateral quadrant undergoes standard orthodontic retraction without corticotomy.

Rate of maxillary canine retraction
Linear distal movement of the maxillary canine measured on CBCT scans relative to a fixed anatomical landmark (e.g., the cusp tip, the center of the tooth (midpoint of the line joining the cusp tip and root apex), and the root apex) to compare the corticotomy-assisted side with the conventional side.
6 months
Overall rate of maxillary canine retraction
Baseline to Post-retraction (6months)
Comparison of amount of canine root resorption between the corticotomy- assisted side and the conventional side.
Baseline to Post-retraction (6months)
Corticotomy will be performed on one maxillary quadrant before initiating standardized canine distalization.
Conventional canine retraction will be performed on the contralateral quadrant without corticotomy under identical orthodontic mechanics.
