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.

Interventions

OTHERMicro-osteoperforations (MOPs)

MOPs included shallow perforations of the buccal cortical plate surrounding the tooth that requires orthodontic tooth movement, with no flap reflection was performed using a surgical bur using the special calibrated device called PROPEL

OTHERConventional canine retraction

using nickel-titanium (NiTi) closed coil-springs delivering a force of 150 grams per side
