Micro-osteoperforations on the Rate of Canine Retraction

Study Overview
=================
Brief Summary
-----------------
the study aimed to clinically evaluate the effect of micro-osteoperforations on the rate of tooth movement, as evaluated by its effect on the rate of canine retraction.

Detailed Description
-----------------
Ten adult patients requiring maxillary first premolars' extraction were enrolled in this split-mouth randomized controlled clinical trial. Micro-osteoperforations were randomly assigned to one side of the maxillary arch at the canine-premolar region, and the contralateral side served as the control. Mini-screws were used for anchorage reinforcement, and canine retraction was performed using nickel-titanium closed coil springs, delivering a force of 150 grams per side. The primary outcome was the measurement of canine retraction rate throughout the study period from digital dental models obtained every 3 weeks. The secondary outcome was the detection of possible canine tipping during retraction.
