BACKGROUND
With the popularity of medical aesthetic programs, some female adults who will or are undergoing orthodontic treatment often wonder whether orthodontic treatment has adverse effects on the nasolabial folds (NLFs). The aims of the study were to investigate any potential changes in the NLFs and associated peripheral soft tissues after orthodontic treatment of female adults.
METHODS
This study compared changes in the NLFs and peripheral soft tissues in female adults undergoing orthodontic treatment using the 3dMD Face system (3dMD, Atlanta, Ga). A total of 52 adult female patient cases (24 teeth extraction, 28 non-teeth extraction) were included to evaluate the effects of different orthodontic treatment regimens on the NLFs and peripheral soft tissues.
RESULTS
In the NLFs area, the landmarks of the extraction group were all significantly negatively changed (P < 0.001; the NLF2s average value was - 0.72 mm), and the upper and middle parts of the landmarks were negatively changed in the non-extraction group (P < 0.05; the NLF2s average value was - 0.22 mm). Compared to the non-extraction group, the negative changes in the extraction group were more pronounced (P < 0.005). In the lip region, all landmarks in the extraction group were negative changes (P < 0.05; upper lip (ULP) = - 0.93 mm, lower lip (LLP) = - 1.46 mm), and most landmarks in the non-extraction group were positive changes (P < 0.01; ULP = 0.55 mm). In the cheek area, the left and right buccal of the extraction and non-extraction groups were all negatively changed (P < 0.05), and there was no significant difference between the two groups.
CONCLUSION
After orthodontic treatment, the NLFs showed negative changes, which were more obvious in the extraction group. The lip soft tissue had a negative change in the extraction group and a positive change in the non-extraction group, indicating that orthodontic treatment affected the soft tissue around the nasolabial sulcus, and that tooth extraction would lead to more negative changes.
背景
随着医美项目的普及，一些即将或正在接受正畸治疗的成年女性常常想知道正畸治疗是否会对面中部鼻唇沟（nasolabial folds，NLFs）产生不良影响。本研究旨在探讨女性成人正畸治疗后 NLFs 及其相关周围软组织的潜在变化。
方法
本研究使用 3dMD Face 系统（3dMD，亚特兰大，GA）比较了正畸治疗的女性成年人的 NLFs 和周围软组织的变化。共纳入 52 例成年女性患者（24 例拔牙，28 例非拔牙），以评估不同正畸治疗方案对 NLFs 和周围软组织的影响。
结果
在 NLFs 区域，拔牙组的标志点均显著负向改变（P<0.001；NLF2s 平均值为-0.72mm），非拔牙组的标志点中上部分负向改变（P<0.05；NLF2s 平均值为-0.22mm）。与非拔牙组相比，拔牙组的负向改变更为明显（P<0.005）。在唇部区域，拔牙组的所有标志点均为负向改变（P<0.05；上唇（ULP）=-0.93mm，下唇（LLP）=-1.46mm），非拔牙组的大多数标志点均为正向改变（P<0.01；ULP=0.55mm）。在颊部区域，拔牙组和非拔牙组的左右颊部均为负向改变（P<0.05），但两组间无显著差异。
结论
正畸治疗后，NLFs 呈负向改变，拔牙组更为明显。唇软组织在拔牙组中出现负向改变，在非拔牙组中出现正向改变，提示正畸治疗会影响鼻唇沟周围的软组织，拔牙会导致更明显的负向改变。
