Abstract

BACKGROUND:

The micro-osteoperforation can be used to increase the rate of tooth movement, simplify complex orthodontic movements, and also help adjust the anchorage but there are conflicting reports on the effectiveness and adverse effects of this intervention.

OBJECTIVES:

The aim of our systematic review and meta-analysis was to evaluate the effects of micro-osteoperforation on the rate of tooth movement in patients undergoing orthodontic treatment.

SEARCH METHODS:

A comprehensive search of MEDLINE, ISI web of science, EMBASE, Scopus, and CENTRAL online databases for studies measuring the effects of micro-osteoperforation on the rate of orthodontic tooth movement from inception to February 2019 was performed.

SELECTION CRITERIA:

Based on the PICO model, human studies which evaluated the effects of MOP on the rate of tooth movement in patients undergoing orthodontic treatment were selected for this review.

DATA COLLECTION AND ANALYSIS:

The relevant data from the eligible studies were extracted using piloted custom extraction forms. The data were combined and analysed using inverse-variance random-effect meta-analysis and the mean difference was used for comparing the outcome measures.

RESULTS:

Six randomized clinical trials were finally included in this meta-analysis. The rate of canine retraction per month was significantly higher in the MOP group [mean difference (MD) = 0.45 mm, 95% CI = 0.17-0.74]. These results were similar with regard to different malocclusions, the jaw on which it was performed, and MOP methods. The patients did not report any significant differences in terms of pain severity levels after MOP. With regard to the adverse effects, one study reported higher amounts of root resorption among patients undergoing MOP.

CONCLUSIONS:

The rate of tooth movement was increased after performing MOP but in at least one study higher root resorption was observed. Therefore, the use of MOP can be recommended after weighing the benefits and disadvantages this intervention can bring for each patient.

REGISTRATION:

The protocol for this review was registered via crd.york.ac.uk/prospero with the ID CRD42019115499.
