摘要
目的探讨自锁托槽非拔牙矫治牙列拥挤的临床效果。方法选择2013年10月-2014年10月本院收治的64例牙列拥挤患者作为研究对象,随机分为试验组与对照组每组32例,对照组采用传统MBT直丝弓托槽非拔牙矫治方法进行治疗,试验组采用自锁托槽非拔牙矫治治疗,对比两组的治疗效果。结果两组患者治疗前后第一磨牙及尖牙间宽度水平无显著差异(P>0.05),试验组患者前磨牙间宽度改善程度显著好于对照组(P<0.05);两组患者治疗后上前牙凸度均有明显提高,其中试验组较对照组提高更加明显(P<0.05)。结论自锁托槽非拔牙矫治牙列拥挤疗效显著,对于提高患者前磨牙间宽度以及上前牙凸度效果显著,适合进行推广。
Objective To investigate the clinical effect of self ligating brackets in the treatment of dental crowding. Meth- ods Selected 64 cases of tooth from October 2013 to October 2014 in our hospital were crowding patients as the research object, randomly divided into experimental group and control group with 32 cases in each group, the control group used the traditional MBT straight wire bracket with non extraction treatment, experimental group was treated with self ligating nonextraction treat- ment, compared two groups of treatment.Results There was no significant difference between the two groups before and after treatment in patients with first molar and canine width level （P〉0.05）, test group of patients with premolar width between the degree of improvement was significantly better than the control group （P〈0.05）; the two groups of patients after treatment of anterior teeth crown were significantly improved, the experimental group than the control group increased more significantly （P 〈 0.05）.Conclusion Self ligating brackets are effective in the treatment of crowding, and it has a significant effect on improving the width of the premolars and the convexity of the anterior teeth.
