The results from the literature regarding the influence of supplemental vibrational forces (SVFs) on orthodontic treatment are controversial. Therefore, this systematic review aimed to evaluate whether SVFs have positive effects, such as in accelerating tooth movement, alleviating pain, and preventing root resorption, in orthodontic patients.
Searches through five electronic databases (PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Central) were complemented by hand searches up to January, 2019.
Randomized controlled trials and controlled clinical trials reporting on the effects of SVFs in orthodontic patients in English were included.
Study selection, data extraction, and a risk of bias assessment were independently performed by two reviewers. Study characteristics and outcomes were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A qualitative analysis of the effects of SVFs on orthodontic tooth movement, pain experience, and root resorption was conducted.
Thirteen studies, including nine clinical trials, were eligible for inclusion in the systematic review. There was no significant evidence to support the positive effects of SVFs in orthodontic patients, neither in accelerating tooth movement nor in alleviating pain experience. According to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria, the quality of the evidence was very low for all the outcomes in the qualitative analysis.
The results of this systematic review are based on a limited number of studies and the methodological heterogeneity and non-comparability of original outcomes made it difficult to conduct a meta-analysis.
There is insufficient evidence to support the claim that SVFs have positive clinical advantages in the alignment of the anterior teeth. The potential positive effects of vibrational forces on space closure, pain experience, and root resorption in orthodontic patients are inconclusive with no sufficient information at present. High-quality clinical trials with larger sample sizes are needed to find more comprehensive evidence of the potential positive effects of vibrational forces.
The protocol for this systematic review was registered on PROSPERO (CRD42018098788).

关于补充振动力量（SVFs）对正畸治疗影响的文献结果存在争议。因此，本系统评价旨在评估 SVFs 是否具有积极作用，例如加速牙齿移动、减轻疼痛和预防牙根吸收，从而改善正畸患者的治疗效果。
对五个电子数据库（PubMed、MEDLINE、EMBASE、Web of Science 和 Cochrane Central）进行检索，并补充截至 2019 年 1 月的手工检索。
纳入研究包括报告 SVFs 对正畸患者影响的随机对照试验和对照临床试验，语言为英文。
两位评审员独立进行研究选择、数据提取和偏倚风险评估。研究特征和结果根据系统评价和荟萃分析的首选报告项目（PRISMA）声明进行报告。定性分析了 SVFs 对正畸牙移动、疼痛体验和牙根吸收的影响。
共有 13 项研究，包括 9 项临床试验，符合本系统评价的纳入标准。没有证据表明 SVFs 对正畸患者具有积极作用，无论是在加速牙齿移动还是减轻疼痛体验方面。根据推荐评估、制定与评价（GRADE）标准，所有定性分析结果的证据质量均为极低。
本系统评价的结果基于有限数量的研究，且原始结果的方法学异质性和不可比性使得难以进行荟萃分析。
没有足够的证据支持 SVFs 在矫正前牙排列方面具有积极的临床优势的说法。目前，振动力量对正畸患者的间隙关闭、疼痛体验和牙根吸收的潜在积极影响尚无定论，信息不足。需要高质量、大样本量的临床试验来寻找更多关于振动力量潜在积极作用的全面证据。
本系统评价的方案已在 PROSPERO（CRD42018098788）上注册。
本研究未从任何私人或公共资助机构获得任何贡献。
无。
