摘要： 目的: 回顾性研究成年女性拔牙正畸治疗后软硬组织三维方向的改变,并分析其相关性以提供临床决策的循证证据。方法: 本研究共纳入40例女性患者,用Dolphin软件对正畸治疗前后的锥形束断层扫描(cone-beam computed tomography,CBCT)数据进行定量分析。结果: 上下唇以及鼻唇沟区软组织治疗前后在矢状向差异均有统计学意义,鼻唇沟区(nasolabial folds,NLF)软组织从上往下变化量逐渐增大(NFL3＞NLF2＞NFL1),从内往外逐渐减小(L2＞NLF2＞L1)。切牙内收量与唇组织变化之间存在中度正相关(r=0.52),上尖牙内收量与鼻唇沟区软组织变化之间也存在中度正相关(r=0.63)。结论: 成年女性拔牙正畸治疗可以有效改善凸面型和唇形态,其切牙和尖牙内收量可用于预测唇及鼻唇沟区软组织矢状向的改变。尽管鼻唇沟区软组织发生了负向改变,但鼻唇沟皱褶是否会加深仍需进一步研究。

Abstract: Objective: To evaluate the three-dimensional changes of soft and hard tissues in adult females after extraction orthodontic treatment. Methods: A total of 40 female cases were included, and the CBCT data before and after orthodontic treatment were quantitatively analyzed using Dolphin software. Results: There is statistically significant difference in the displacement of upper and lower lips, as well as the soft tissue around nasolabial folds along the sagittal direction. The changes of soft tissue around nasolabial folds showed a gradual increase (NFL3＞NLF2＞NFL1) and a gradual decrease from the inside to the outside (L2＞NLF2＞L1). There was a moderate positive correlation between incisor retraction and changes in lip tissue (r=0.52), as well as a moderate positive correlation between upper canine retraction and changes in soft tissue around nasolabial folds(r=0.63). Conclusion: The convex facial profile and lip morphology can be effectively improved after extraction orthodontic treatment in adult females. The retraction of incisors and canines can be used to predict changes of lips and soft tissue around nasolabial sulcus in the sagittal direction. Although the soft tissue around nasolabial folds showed negative changes, further research is needed to determine whether the folds in the nasolabial folds will deepen.
