This single-blinded, split-mouth randomized controlled trial investigates whether micro-osteoperforations (MOPs) can accelerate maxillary canine retraction in orthodontic patients requiring bilateral premolar extraction. The study also evaluates postoperative pain levels using the Visual Analog Scale at 1, 3, and 7 days.
MOPs are a flapless, minimally invasive surgical technique that stimulates bone remodeling and may reduce orthodontic treatment time. In this trial, one side of each patient receives MOPs while the contralateral side serves as control. Canine retraction is performed using miniscrews, power arms, and NiTi coil springs. Outcomes include the rate of canine movement over 16 weeks and pain assessment using VAS.

Rate of Maxillary Canine Retraction
Distance of maxillary canine retraction measured on 3D digital dental models using intraoral scanning.
Time frame: Baseline, 4, 8, 12, and 16 weeks
Pain Level (VAS Score)
atient-reported pain intensity measured using a 10-cm Visual Analog Scale (VAS), with scores ranging from 0 (no pain) to 10 (worst pain imaginable).
Time frame: Day 1, Day 3, Day 7 after intervention
