目的:对比研究钢丝-树脂夹板固定与牙弓夹板固定在半脱位恒前牙固定方式的临床效果.方法:收集2008 ～ 2012年就诊于我院的132例牙外伤患者的152颗半脱位恒前牙完整病例资料,进行回顾性研究,并进行统计学分析.结果:152颗半脱位恒前牙中有钢丝-树脂夹板固定93颗,牙弓夹板固定59颗,两种固定方法成功率分别为95.69％和88.13％,钢丝-树脂夹板固定技术在控制牙外形、牙弓形态、远期效果上优于牙弓夹板技术,差异有统计学意义(P＜0.05).结论:两种方法在半脱位恒前牙固定中均疗效肯定,但钢丝-树脂夹板固定技术应其预后效果良好,更宜在临床推广.%Objective: To study the clinical effect of ultrastrength textile fiber in the fixation of dislocated tooth. Methods Collecting material of 152 subluxation of permanent anterior teeth from 132 patients with dental trauma during year 2008 to 2012. A retrospective study was carried out, and statistical analysis. Results 93 teeth used steel wire resin splint fixation in 152 permanent anterior teeth, 59 teeth were dental arch splint, the success rate of two different fixation methods were 95.69% and 88.13%, steel wire resin splint fixation technology in the control of dental arch form, shape, long-term effect is better than that of dental arch splint technique, the difference was statistically significant (P< 0.05). Conclusion Two kinds of treatments of Subluxation of permanent anterior teeth fix are effective, but Steel wire resin splint fixation technique attended with good results,suitable for clinical application.
