This single-centered randomized clinical trial evaluated the effects of micro-osteoperforations in the retraction of maxillary incisors in patients who required the extraction of the first premolars to correct malocclusion. The canine retraction was performed in a previous step. The possible effects of micro-osteoperforantions in the following parameters were evaluated in the upper arch: anteroposterior incisors and first molars displacement, space closure, inclination and length of central incisors.
This clinical trial evaluated the efficacy of micro osteoperforations in accelerating the retraction of maxillary incisors.
