目的:探讨Begg矫治器和直丝弓矫治器联合治疗安氏Ⅱ类1分类错颌畸形的临床疗效。方法:采取回顾性分析方法,调阅2010-2013年徐州矿务集团总医院安氏Ⅱ类1分类错颌畸形患者病历资料,选择病历资料完整且符合本研究要求的正畸病人病历44例进行分析,实验组22例为Begg矫治器和直丝弓矫治器联合治疗组,对照组22例为单纯直丝弓治疗组。对治疗前后的头影测量片进行扫描分析,对治疗时间及辅助支抗应用情况进行统计分析。结果:治疗完成时,Begg矫治器和直丝弓矫治器联合治疗组和单纯直丝弓治疗组的前牙覆合覆盖均减少,上切牙切缘均向远中移动,上下磨牙均伸长,前下面高度均增加,两组治疗结束后硬组织的变化无统计学差异(P>0.05)。Begg矫治器和直丝弓矫治器联合治疗组与单纯直丝弓治疗组相比,治疗时间短,使用辅助支抗少,差异具有统计学意义(P<0.05)。结论:Begg矫治器和直丝弓矫治器联合矫治安氏Ⅱ类1分类错颌畸形是临床上一种速度快,费用低,效果优的治疗方法。
Objective: To investigate the clinical effect of Begg orthotic and straight wire appliance in the treatment of Class Ⅱ division 1 malocclusion. Methods: A retrospective analysis method was used to refer to the medical records of patients with Class Ⅱ division 1 malocclusion in the General Hospital of Xuzhou Mines from 2010 to 2013. 44 cases of orthodontic patients were selected according to the data of the medical records. Analysis, experimental group, 22 cases of Begg appliance and straight wire appliance combination therapy group, control group, 22 cases of simple straight wire treatment group. Before and after treatment of cephalometric measurement of the scanning analysis of the treatment time and the application of auxiliary support for statistical analysis. Results: At the end of treatment, the coverage of anterior teeth in Begg and Straight wire appliance group and straight wire appliance group were all reduced, the incisor margin of upper incisors moved to the far, the upper and lower molar teeth were all elongated, There was no significant difference in hard tissue between the two groups after treatment (P> 0.05). Compared with the simple straight-wire treatment group, the treatment time of Begg orthotic and straight-wire appliance was shorter, and the number of auxiliary braces was less, the difference was statistically significant (P <0.05). Conclusion: The combination of Begg appliance and straight wire appliance in the treatment of Class Ⅱ division 1 malocervical deformity is a fast, cheap and effective method in clinical practice.
