目的探讨正畸弓丝固定前牙外伤的临床效果。方法回顾性分析某院自2008年1月～2010年10收治的因外伤前牙需进行正畸固定的患者32例,共计牙齿53颗,53颗牙齿均用正畸固定技术进行前牙固定,其中应用不锈钢方丝25颗,镍钛圆丝28颗,比较其临床疗效,操作时间及并发牙周炎的情况。结果不锈钢方丝组总有效率为80.0%,镍钛方丝组总有效率为71.4%,两组总体疗效比较,P﹥0.05。不锈钢方丝组,镍钛方丝组发生牙周炎及手术时间,两组比较,P﹤0.05。结论应用不锈钢方丝与镍钛方丝正畸技术固定外伤前牙均可取得一定的临床疗效,但两种弓丝临床应用特点不同,可根据临床具体情况进行选择。
Objective To investigate the clinical effect of orthodontic arch wire fixation of anterior tooth trauma. Methods A retrospective analysis of a hospital from January 2008 to 2010, 10 patients admitted to orthodontic treatment of traumatic anterior teeth required for 32 cases, a total of 53 teeth, 53 teeth orthodontic fixation techniques for anterior teeth fixation, The application of stainless steel square wire 25, nickel-titanium wire 28, compare its clinical efficacy, operation time and concomitant periodontitis. Results The total effective rate of the stainless steel square wire group was 80.0%, the total effective rate of the nickel titanium square wire group was 71.4%, the overall curative effect of the two groups was compared, P> 0.05. Periodontitis and operation time occurred in stainless steel square wire group and nickel titanium square wire group, P <0.05. Conclusion The application of stainless steel square wire and nickel-titanium square wire orthodontic technique to fix the anterior trauma can achieve some clinical curative effect. However, the clinical application of the two kinds of arch wire is different and can be selected according to the clinical situation.
