This study aims to evaluate the effectiveness of various supplementary vibrational frequencies with orthodontic force on the rate of canine movement.
A literature search was conducted in PubMed, Embase, Cochrane, Scopus, ClinicalTrials.gov, and Google Scholar, with the final search on February 17, 2025. Randomized controlled trials (RCTs) involving participants undergoing orthodontic treatment with upper first premolar extraction, assessed the effect of different vibration frequencies on canine movement rate were included. Study quality was assessed using the Risk of Bias (RoB) 2. A random-effects model (DerSimonian and Laird method) for pairwise meta-analysis (PMA) and a frequentist-based network meta-analysis (NMA) estimated relative effects, with mean difference (MD) and 95% confidence interval (CI) calculated for all comparisons. The certainty of evidence was assessed using the Confidence in Network Meta-Analysis tool.
Ten RCTs examined the effects of five vibration frequencies. The RoB ranged from low to high. The PMA found vibrations significantly increased tooth movement (MD = 0.084 mm, 95% CI [0.004, 0.164]). Conversely, NMA showed no significant differences across all comparisons. The Surface Under the Cumulative Ranking Curve ranked 125 Hz as the most effective, followed by 100, 60, 30, and 0 Hz. The confidence in evidence ranged from low to moderate.
The use of supplementary vibration in conjunction with orthodontic force statistically effectively accelerates tooth movement, with higher frequencies showing a tendency to yield better acceleration results.
While vibration therapy demonstrated a statistically significant effect on canine movement, the magnitude of this effect was not sufficient to be considered clinically significant for orthodontic treatment. Further research is required to optimize the effectiveness.
本研究旨在评估正畸力作用下各种辅助振动频率对犬齿移动速率的有效性。
在PubMed、Embase、Cochrane、Scopus、ClinicalTrials.gov和谷歌学术进行文献检索，最后一次检索时间为2025年2月17日。纳入涉及接受拔除上颌第一前磨牙正畸治疗参与者的随机对照试验（RCT），评估不同振动频率对犬齿移动速率的影响。使用偏倚风险（RoB）2评估研究质量。采用随机效应模型（DerSimonian和Laird方法）进行成对荟萃分析（PMA）和基于频率学派的网络荟萃分析（NMA）估计相对效应，所有比较均计算平均差（MD）和95%置信区间（CI）。使用网络荟萃分析置信度工具评估证据的确定性。
10项RCT研究了5种振动频率的影响。RoB范围从低到高。PMA发现振动显著增加牙齿移动（MD = 0.084 mm，95% CI [0.004, 0.164]）。相反，NMA显示所有比较均无显著差异。累积排名曲线下面积将125 Hz列为最有效，其次是100、60、30和0 Hz。证据的置信度范围从低到中等。
正畸力联合使用辅助振动在统计学上有效加速牙齿移动，较高频率显示出产生更好加速效果的趋势。
虽然振动疗法对犬齿移动显示出统计学上的显著效果，但这种效果的大小不足以在正畸治疗中被认为具有临床意义。需要进一步研究以优化有效性。
