摘要:
目的：探讨安氏Ⅱ类1分类错牙合畸形患者应用Twin-block功能矫治器（TB）联合自锁托槽后的临床效果。方法：前瞻性选取2015年10月-2018年10月笔者医院收治的102例安氏Ⅱ类1分类错牙合畸形患者。按治疗方式的不同分为对照组和观察组，每组51例。对照组采用传统MBT直丝弓矫治器进行治疗，观察组采用TB联合自锁托槽进行治疗。比较两组临床疗效、头影测量指标、软组织变化情况及同行评估等级（PAR）指数。结果：观察组总有效率（94.12%）高于对照组（80.39%），差异有统计学意义（P＜0.05）。两组上齿槽座角、下齿槽座角、上下齿槽座角、下颌平面角、下中切牙长轴与下颌平面间夹角、上切牙的倾斜度比较，差异均无统计学意义（P＞0.05）；观察组下切牙的倾斜度高于对照组（P＜0.05）；两组上唇基角、下唇基角比较，差异均无统计学意义（P＞0.05）。观察组全面凸角、软组织面角均高于对照组，差异有统计学意义（P＜0.05）。治疗前，两组PAR指数总分比较，差异无统计学意义（P＞0.05）；治疗后，观察组PAR指数总分低于对照组，且治疗前后差值高于对照组，差异有统计学意义（P＜0.05）。结论：安氏Ⅱ类1分类错牙合畸形患者应用TB联合自锁托槽具有良好的矫正效果，可调整上下颌关系，纠正软组织畸形。
Abstract:
Objective To investigate the curative effect of Twin-block functional appliance combined with self-ligating bracket in the treatment of angle Class Ⅱ division 1 malocclusion. Methods Total of 102 patients with angle Class Ⅱ division 1 malocclusion in our hospital from October 2015 to October 2018 were prospectively selected. According to the different treatment methods, the patients were divided into the control group (n=51) and the observation group (n=51). The control group was treated with a traditional MBT straight wire appliance, and the observation group was treated with a Twin-block functional appliance combined with self-ligating bracket. The clinical efficacy, cephalometric indicators, soft tissue changes and peer assessment rating (PAR) index were compared between the two groups. Results The total eff ective rate of the observation group (94.12%) was higher than that of the control group (80.39%), and the diff erence was statistically significant (P＜0.05). There was no significant difference between the two groups of upper alveolar seat angle, lower alveolar seat angle, upper and lower alveolar seat angle, mandibular plane angle, the angle between the long axis of the mandibular incisor and the mandibular plane, and inclination of upper incisor (P＞0.05).The inclination of lower incisor in the observation group was higher than that in the control group, and the difference was statistically significant (P＜0.05). There was no significant diff erence between the two groups of upper lip base angle and lower lip base angle (P＞0.05). The overall convex angle and soft tissue face angle of the observation group were higher than those of the control group, and the diff erences were all statistically significant (P＜0.05). Before treatment, there was no significant diff erence in the total score of PAR index between the two groups (P＞0.05). After treatment, the total score of PAR index in the observation group was lower than that of the control group, and the difference before and after treatment in the observation group was higher than that of the control group, and the differences were all statistically significant (P＜0.05). Conclusion The application of Twin-block functional appliance combined with self-ligating bracket has a good corrective effect for patients with angle Class Ⅱ division 1 malocclusion, which can adjust the relationship between the upper and lower jaw and correc t soft tissue deformity
