ABSTRACT
Introduction: The long passing time for tooth movement (TM) is one of the challenges in orthodontic. complications such as gingival recession, root resorption, and caries are common in orthodontic. To address this, there is an increased tendency to find safe and effective methods to accelerating tooth movement. A surgical method such as micro-osteoperforations (MOP) accelerating the TM. The current meta-analysis aims to investigate the outcome of MOP in accelerating TM in animal studies. Methods: In the present meta-analysis, we evaluated 6 studies that focused on the effect of MOP on TM with the following keywords: (((MOP* OR micro-osteoperforations*) AND (("accelerating tooth movement " OR " tooth movement" AND " orthodontic tooth movement " OR " orthodontic ") until May 2021. Results: The results have shown there is significant difference in TM after using MOP (MD: 0.31, 95%CI: 0.20, 0.42, P < 0.00001, I2 = 76%). Subgroup analysis revealed that though experimental duration in both less than 4-week and more than 4-week, the TM were significant difference between MOP and controls. Besides, in both force subgroups including less than 100 g and more than 100g, the TM was a significant difference between MOP and controls. Conclusion: This meta-analysis found that generally MOP has a positive effect on TM.
