Summary

This clinical trial evaluated the efficacy of micro osteoperforations in accelerating the retraction of maxillary incisors.

Detailed description

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.

Conditions

• Orthodontic Tooth Movement

Interventions

Type	Name	Description
PROCEDURE	Micro-osteoperforations	All micro-osteoperforations were performed only one time in the experimental group on the same day of the installation of the upper incisors' retraction mechanics. Perforations were performed with an individualized surgical guide and a 1.6 mm diameter stainless steel surgical drill perpendicular to the alveolar bone, 3 mm deep on the buccal surface, and 5 mm, on the palate. The depth of the perforations was controlled and standardized by a cursor developed and patented by the research group. Two micro-osteoperforations were aligned vertically distally from each upper incisor. Due to the proximity of the roots in the cervical third, only the most apical perforation was performed between the two central incisors. The first perforation was performed 6 mm away from the gingival margin, and the second, 5 mm from the first, in the vertical direction.
