This randomized controlled trial examined the effectiveness of micro-osteoperforations (MOPs) in enhancing en-masse anterior retraction to reduce orthodontic treatment duration and minimize anchorage loss. The study involved 40 adult patients needing bilateral maxillary first premolar extractions, divided into MOPs and control groups. The primary outcomes measured were the rate of anterior retraction and total treatment duration, while secondary outcomes included anchorage loss and changes in incisor inclination and root length. Results showed a significant increase in retraction rate in the MOPs group (1.00 ± 0.20 mm/month) compared to the control group (0.72 ± 0.18 mm/month) over four months (P < 0.01). No significant differences in molar anchorage loss were found between groups (P > 0.05), indicating that MOPs can accelerate tooth movement without affecting posterior stability. The study concludes that MOPs are a safe and effective method for speeding up en-masse anterior retraction, thus enhancing the overall orthodontic treatment experience.
