Many patients, particularly adults, may prefer clear aligner treatment due to its esthetics and ease of use. Some studies have shown that mechanical vibration can affect the rate of tooth movement and other aspects of orthodontic treatment. The purpose of this systematic review was to substantiate the effects of vibration as an adjunct to clear aligner treatment. A comprehensive search of the PubMed, Embase, Cochrane library, and Scopus and also hand searching of reference lists was conducted for finding published studies up to March 2021. Two authors reviewed the titles and abstracts independently to select relevant studies and the full texts where there was some skepticism. Seven papers were included in this study following removing duplicates and irrelevant studies, four of which were randomized controlled trial and three were retrospective studies. In the majority of studies, High-Frequency Vibration (HFV) has shown to be effective in accelerating tooth movement and reducing the exchange interval of aligners. Little data have advocated that HFV can increase bone density, reduce pain or root resorption. It seems that HFV is more effective than low frequency vibration in patients treated with clear aligners. Based on a low level of certainty, HFV can increase the rate of tooth movement and decrease the exchange interval of clear aligners. Further investigation is necessary to clarify the effects of vibration on pain and discomfort, bone density, and root resorption.
许多患者，尤其是成年人，可能会因隐形矫治器的美观性和易用性而更喜欢这种治疗方式。一些研究表明，机械振动会影响牙齿移动速度和正畸治疗的其他方面。本系统评价的目的是证实振动作为隐形矫治器治疗辅助手段的效果。对PubMed、Embase、Cochrane图书馆和Scopus进行了全面检索，并人工检索参考文献列表，以查找截至2021年3月发表的研究。两位作者独立审查标题和摘要，以选择相关研究以及存在疑问时的全文。在去除重复和不相关研究后，本研究纳入了7篇论文，其中4篇为随机对照试验，3篇为回顾性研究。在大多数研究中，高频振动（HFV）已被证明在加速牙齿移动和缩短矫治器更换间隔方面有效。很少有数据表明HFV能增加骨密度、减轻疼痛或减少牙根吸收。在接受隐形矫治器治疗的患者中，HFV似乎比低频振动更有效。基于低确定性，HFV可提高牙齿移动速度并缩短隐形矫治器的更换间隔。有必要进一步研究以阐明振动对疼痛和不适、骨密度以及牙根吸收的影响。
