口腔正畸矫正术中弓丝的应用方法与效果探讨

Discussion on the application method and effect of arch wire in orthodontics

目的探讨和研究在口腔正畸矫正术中弓丝的应用对口腔患者的临床效果。方法选取我院于2011年8月~2017年6月收治的60例错颌畸形患者作为研究对象,随机平均分为研究组、对照组,研究组运用镍钛合金弓丝,对照组采用普通不锈钢弓丝,两组患者采用不同材质弓丝进行口腔正畸矫正术后,比较治疗前1周和后1、3、6个月的菌斑指数(PLI)、牙龈指数(GI)的变化情况,以及比较6个月内两组患者的弓丝断裂、托槽脱落次数和VAS评分。结果采用镍钛合金弓丝研究组的菌斑指数、牙龈指数显著低于对照组,且6个月内两组患者的弓丝断裂、托槽脱落次数和VAS评分显著优于对照组,差异有统计学意义(P<0.05)。结论镍钛合金弓丝在口腔正畸矫正术中可显著促进患者口腔健康,提高患者生活质量,值得临床广泛应用。

Objective To investigate and study the clinical effect of the application of arch wire in orthodontic correction on oral patients.Methods Sixty patients with malocclusion admitted to our hospital from August 2011 to June 2017 were selected as the research objects and randomly divided into the research group and the control group on average.The study group was used nickel-titanium alloy arch wire,while the control group was used ordinary stainless steel arch wire.Two groups of patients were treated with orthodontics by using different material archwires.The changes of plaque index(PLI)and gingival index(GI)in the first week before treatment and the 1st,3rd and 6th months after treatment were compared,and the arch wire breakage,bracket shedding times and VAS scores of the two groups of patients within the 6th month were compared.Results The plaque index and gingival index of the study group were significantly lower than those of the control group.And in 6 months,arch wire breakage,bracket shedding times and the VAS score of the two groups were significantly better than those of the control group(P<0.05).Conclusion Nickel titanium arch wire can significantly promote oral health and improve the quality of life in orthodontics.It is worthy of wide clinical application.
