The effect of micro-osteoperforation (MOP) in molar distalization treatments: an exploratory systematic review and meta-analysis of RCTs.

This article systematically reviews and meta-analyzes the effects of micro-osteoperforation (MOP) on molar distalization, a common orthodontic procedure for correcting Class II malocclusions. Based on four randomized clinical trials involving 71 adult participants, the analysis found no significant difference in the rate or amount of molar distalization between patients treated with MOP and those without. However, MOP was associated with significantly increased pain on the day of the procedure, which subsided within a week. The review highlights that while MOP may cause transient discomfort and mild root resorption, it does not substantially accelerate tooth movement, suggesting its use should be limited to complex or prolonged cases where other methods are insufficient. Limitations include the small number of studies and variability in MOP protocols, indicating a need for standardized approaches and further research on specific clinical scenarios.
