Micro-osteoperforations for accelerating tooth movement during canine distalization, split-mouth study. Case report

Abstract

Recent publications done in well-recognized journals of orthodontics, assure that micro-osteoperforations (MOP) enhance the process of bone remodeling and accelerate dental movement. Its application is easy, fast and can be performed by the orthodontist. Objective: The objectives are to evaluate and compare canine distalization time in young patients, by using both an acceleration technique through MOP and a conventional technique in a split-mouth design. 1. Find the best procedure to accelerate an orthodontic treatment with extractions. 2. Decrease treatment time. Material and methods: Canine distalization was performed on 10 young patients whose treatment plan included fi rst premolar extractions. MOP was performed in the first premolar extraction zone of the right quadrant. A mini-implant was placed between the second premolar and the fi rst molar in order to obtain absolute anchorage. Traction was applied by using power chains on both sides. In the left quadrant canine distalization was performed through conventional methods. Results: The obtained results in the side where MOP was performed, show a signifi cant reduction in the procedure time when compared with conventional treatment. Conclusions: Canine distalization acceleration using MOP in patients with extractions leads to highly effective results; up to 41% faster space closure. This results in a shorter and more comfortable orthodontic treatment for the patient.
