The current systematic review appraises the effectiveness of the types of tooth movements performed with Invisalign clear aligner on the maxillary incisors. An electronic literature search of published trials was performed through PubMed, LILACS, Scopus, Cochrane Library, and Web of Science databases, and selected journals, from 2009 to 2020. Out of 291 references, five relevant publications were identified for analysis: four studies were performed retrospectively and one prospectively, all non-randomized. Despite the limited set of selected articles, the sample size is significant, with 148 subjects included in the reviewed studies involving the orthodontic treatment of upper incisors. We concluded that movements with the Invisalign clear aligner on the upper incisors present distinct accuracy, possibly related with movement complexity; intrusion of the incisors has low accuracy (in some cases, 0% of accuracy was reported when the tooth extruded), while incisor extrusion exhibit some of the highest accuracy values reported in the included studies (45%-142%, when the achieved movement was greater than the predicted). Besides, axial (i.e., torque and tip) and horizontal (i.e., translation and rotation) movements are usually effective, with accuracy values between 39%-156% and 42%-79%, respectively. Overall, we determined that the efficiency of aligner to reach the desired movements in the upper incisors was low, as often refinements were required in the included studies. The use of aligner features must be more often considered to improve movement accuracy.
本系统评价评估了使用隐适美透明矫治器对上颌切牙进行的各类牙齿移动的有效性。通过PubMed、LILACS、Scopus、Cochrane图书馆和Web of Science数据库以及选定的期刊，对2009年至2020年发表的试验进行了电子文献检索。在291篇参考文献中，确定了5篇相关出版物进行分析：4项研究为回顾性研究，1项为前瞻性研究，均为非随机研究。尽管所选文章数量有限，但样本量可观，纳入综述研究的148名受试者涉及上颌切牙的正畸治疗。我们得出结论，使用隐适美透明矫治器对上颌切牙进行的移动具有明显的准确性，这可能与移动的复杂性有关；切牙的压低准确性较低（在某些情况下，当牙齿出现伸长时，报告的准确率为0%），而切牙的伸长在纳入研究中显示出一些最高的准确率值（当实现的移动大于预测值时，为45%-142%）。此外，轴向（即转矩和倾斜）和水平（即平移和旋转）移动通常是有效的，准确率分别在39%-156%和42%-79%之间。总体而言，我们确定矫治器在上颌切牙达到期望移动的效率较低，因为纳入研究中经常需要进行调整。必须更频繁地考虑使用矫治器的特征来提高移动准确性。
