To evaluate the facial aesthetic effects of orthodontic treatment performed with clear aligners and to compare it to an untreated control group, on lower third facial ageing in adult patients through the use of the Wrinkle Severity Rating Scale (WSRS) at the beginning (T0) and at the end (T1) of the study period.
A clear aligners treated group (TG) of 68 patients was compared to a control group of 33 untreated patients (UG). Each group was divided in 2 subgroups according to age: subgroup 1 if under 40 years of age and subgroup 2 if over. Facial aesthetics of the lower third was evaluated at T0 and T1 by a panel of five aesthetic experts with WSRS.
Statistically significant changes were found in all subgroups comparing WSRS scores at T0 and T1. The between group comparisons revealed that wearing clear aligners produces a statistically relevant improvement in lower third facial aesthetics both in younger (< 0.05) and older (< 0.001) patients.
The present retrospective cohort study has successfully shown that malocclusion therapy conducted through the use of clear aligners in a population of adults affected by dental crowding has beneficial effects on lower third facial ageing.

通过在研究开始时（T0）和结束时（T1）使用皱纹严重程度评定量表（WSRS），评估成年患者使用透明矫治器进行正畸治疗的面部美学效果，并与未治疗的对照组进行比较，以观察对下三分之一面部老化的影响。
将68例接受透明矫治器治疗的患者组成治疗组（TG），与33例未治疗患者组成的对照组（UG）进行比较。每组根据年龄分为2个亚组：40岁以下为亚组1，40岁以上为亚组2。在T0和T1时，由五名美学专家组成的小组使用WSRS评估下三分之一面部的美学效果。
比较T0和T1时的WSRS评分，所有亚组均发现有统计学意义的变化。组间比较显示，佩戴透明矫治器在年轻患者（<0.05）和老年患者（<0.001）中均能使下三分之一面部美学得到统计学上显著的改善。
本回顾性队列研究成功表明，在受牙列拥挤影响的成年人群中，使用透明矫治器进行错牙合畸形治疗对下三分之一面部老化具有有益效果。正畸学、透明矫治器、面部美学、面部皱纹、依从性。
