目的:分析牙齿畸形患者通过直丝弓与方丝弓矫治器治疗的效果。方法:研究来自我院在2014年3月至2015年3月接诊的牙齿畸形的患者,将患者分为直丝弓组和方丝弓组各40例,分别采用直丝弓与方丝弓矫治器治疗,而后分析两组或治疗前后PAR指数差异的效果对比。结果:通过直丝弓矫正的患者后排牙齿排列的PAR指数要少于方丝弓矫正患者,其效果要优于方丝组,而其余各指标在治疗前后两种方式没有显著性差异,同时在治疗疗上,直丝组时间得到了有效的缩短。结论:对于牙齿排列畸形通过直丝弓矫正可以达到更快的治疗效果,同时在后牙的排列定位效果上有更优质的效果。
OBJECTIVE: To analyze the effect of orthodontic treatment on patients with dental malformations by means of straight wire arch and square wire appliance. Methods: The patients with dental malformations from March 2014 to March 2015 in our hospital were studied. The patients were divided into 40 cases of straight-line arch group and square-arch group, respectively. Straight-line arch and square arch Appliance treatment, and then analysis of the effect of PAR index difference between the two groups or before and after treatment. Results: The PAR index of posterior teeth arranged by straight wire arch was less than that of orthodontic arch wire, the effect was better than that of square wire group, while the other indexes had no significant difference before and after treatment In the treatment of treatment, straight wire group time has been effectively shortened. CONCLUSIONS: Faster treatment can be achieved for orthodontic tooth alignment through straight wire arch correction with better results in arranging posterior teeth.
