| 摘 要： | 目的:探讨Twin-block矫治器早期矫治对安氏Ⅱ类骨性错患者软、硬组织的影响。方法:前瞻性选择60例安氏Ⅱ类骨性错患者为研究对象,应用随机数字表法将患者分为2组,每组各30例。实验组采用Twin-block联合直丝矫治器治疗,对照组采用直丝矫治器治疗。观察2组矫治前、矫治后12个月、36个月硬组织指标（SNA、SNB、ANB、U1-NA夹角、U1-NA距离、L1-NB距离、L1-NB夹角、U1-L1夹角）和软组织测量指标[UL-U1、LL-L1、覆盖（over jet）、覆（overbite）、上唇突点至E 线的垂直距离（E-upper-lip）、下唇突点至E 线的垂直距离（E-lower-lip）、颏沟倾角、颏软组织厚度]的变化。采用SPSS 25.0软件包对数据进行统计学分析。结果:实验组矫治后12个月、36个月U1-NA、U1-NA、L1-NB、L1-NB、覆盖、覆、E-upper-lip、E-lower-lip显著小于对照组（P<0.05）,U1-L1、鼻唇角、颏沟倾角、颏软组织厚度显著大于对照组（P<0.05）。结论:Twin-block联合直丝矫治器可显著改善安氏Ⅱ类骨性错患者口颌以及面部软、硬组织关系,远期效果良好。 |

| Abstract: | PURPOSE: To investigate the effect of early correction with Twin-block appliance on soft and hard tissues of patients with Class Ⅱ skeletal malocclusion. METHODS: Sixty patients with Angle Class Ⅱ skeletal malocclusion were prospectively selected. The patients were divided into 2 groups, 30 cases in each group, by random number table method. Patients in the experimental group were treated with a Twin-block appliance combined with straight wire appliance, while patients in the control group were treated with a straight wire appliance. The soft and hard tissue indexes(SNA, SNB, ANB, U1-NA angle, U1-NA distance, L1-NB distance, L1-NB angle, U1-L1) before, and 12 months after treatment were measured. Soft tissue measurement indicators included UL-U1, LL-L1, over jet, overbite, E-upper-lip from the upper lip to the E-line, and the lower lip to the E-line, changes in the vertical distance (E-lower-lip), the dip angle of the sulcus, and the thickness of the soft tissue. SPSS 25.0 software package was used for statistical analysis of the data. RESULTS: U1-NA, U1-NA, L1-NB, L1-NB, overjet, overbite, E-upper-lip, and E-lower-lip were significantly less than the control group at 12 months and 36 months after treatment in the experimental group(P<0.05). U1-L1, nasolabial angle, sulcus angle, and soft tissue thickness of the experimental group were significantly greater than those of the control group(P<0.05). CONCLUSIONS: Twin-block appliance combined with straight wire appliance can significantly improve the relationship between the jaw and the soft and hard tissues of patients with Class Ⅱ skeletal malocclusion, and the long-term effect is good. |
