摘要： 目的: 研究在进食时隐形矫治器佩戴与否对后牙垂直向高度的影响,探讨进食时佩戴隐形矫治器的必要性。方法: 选择使用隐形矫治器治疗的60例非拔牙矫治患者进行前瞻性研究。根据进食时是否佩戴隐形矫治器分为实验组和对照组,每组各30例。实验组进食时佩戴隐形矫治器,对照组进食时不佩戴隐形矫治器。比较两组治疗前后上下颌第一恒磨牙(U6、L6)垂直向位移距离及上下颌骨垂直向骨性改变。所有统计分析均使用SPSS 25.0软件进行。结果: 两组间相比,治疗前后上下颌磨牙高度、S-Go/N-Me(%)、FMA(°)、OP-FH(°)、MP-OP(°)差值无显著差异(P>0.05)。结论: 进食时是否佩戴隐形矫治器对后牙垂直向高度的影响无明显差异。

Abstract: Objective: To investigate the difference between eating with aligners (EWA) and eating without aligners (EWOA) on the vertical height of posterior teeth. Methods: A prospective study was performed on 60 subjects selected for treatment with invisible appliance, all of whom were treated without tooth extraction. The patients were divided into the experimental group and control group according to whether or not they wore the invisible appliance while eating, with 30 cases in the experimental group and 30 cases in the control group. The experimental group was suggested to wear the invisible appliance to eat, while the control group did not wear the invisible appliance to eat. The vertical displacement distance of the first maxillary molars (U6 and L6) and the bone changes of the upper and lower mandible were compared between two groups before and after treatment. Results: There were no significant differences between two groups in molar height, S-Go/N-Me (%), FMA(°), OP-FH(°), and MP-OP(°) before and after treatment (P>0.05). Conclusion: There was no effect on the vertical height of posterior teeth by wearing an invisible orthodontic device when eating.
