Comparison of canine retraction rate between miniscrew assisted micro-osteoperforation and conventional technique–a systematic review and meta-analysis

Background: One of the major challenges of orthodontics is to reduce the treatment time by achieving maximum results in a specific timeline. The current review aimed to systematically gather data for the synthesis of results to increase evidence. Objective: To determine the difference in canine retraction rate between micro-osteoperforation (MOP) and conventional technique (CT) in patients Methods: Online databases (PubMed, Dental and Oral Science, CINAHL, and Cochrane Central Register of Controlled Trials) were looked up for articlesuntil July 2022. MOP was considered as an intervention whereas the CT was taken as a control to assess the rate of tooth movement. Eligibility Criteria: Six randomized control trials (RCT) were included in this study which reported the canine retraction rate with MOP and CT over the period of 3 months. Data Collection and Analysis: Online databases were used to extract the data. The risk of bias in clinical trials was assessed with (RoB) 2.0. The meta-analysis was conducted using the RevMan software V.5.3.5.22. The outcome was estimated using weighted average difference and 95% confidence intervals (CIs). The studies’ heterogeneity was assessed using Cochrane’s heterogeneity test (I² Test). Results: The rate of tooth movement was assessed at pre- and post-canine retraction in 125 patients who underwent canine retraction under MOP versus conventional technique. There was a statistically significant difference in canine retraction rate between miniscrew assisted MOP and conventional technique (95% CI: 0.05, 0.19). Conclusion: Micro-osteoperforation can be used clinically to accelerate orthodontic tooth movement by reducing the treatment time. Registration: PROSPERO (CRD42022331904).
