目的：对比观察在急性年轻恒前牙脱位中，直丝弓片段弓与传统牙弓夹板两种固定技术的临床疗效。方法在口腔科急诊就诊的年轻恒前牙脱位患者共64例，随机分为两组。A组32例（46颗患牙），采用直丝弓片段弓固定技术；B组32例（38颗患牙），采用传统牙弓夹板固定技术。常规复位固定后，随访观察1年，对比两种固定方法的临床效果。结果采用直丝弓片段弓固定技术的32例患者（46颗患牙）中，成功43颗，有效3颗，失败0颗，总有效率为100%；采用传统牙弓夹板固定技术的32例患者（38颗患牙）中，成功30颗，有效3颗，失败5颗，总有效率为86.84%。对两组的总有效率进行显著性检验，P<0.05，两组间差异有统计学意义。结论急性年轻恒前牙脱位进行再植固定，直丝弓片段弓固定技术效果良好，明显优于传统牙弓夹板固定技术，是目前临床上较为理想的固位方法，值得临床推广应用。“,”Objective To compare the clinical curative effect of straight wire segment arch and traditional dental arch splint fixation techniques in resetting and fixing acute dislocated young permanent anterior teeth. Methods Sixty-four patients, aged 8~18, with young permanent anterior teeth dislocation who visited department of stomatology emergency in Meitan General Hospital in between 2007 and 2012 were selected and randomly divided into two groups, group A of 32 patients (46 teeth), of which straight wire segment arch fixation techniques was adopted;group B of 32 patients (38 teeth) of which the traditional dental arch splint fixation techniques was adopted. A comparison on clinical effect was made between the two fixation techniques in the one year follow-up visit. Results It reflected 43 successful replantation and 3 acceptable (100%effectiveness) in group A, while 30 successful replantation, 3 acceptable, and 5 failing (86.64% effectiveness), carrying out a statistical difference (P<0.05). Conclusion Comparing with the traditional dental arch splint fixation techniques, the straight wire segment arch fixation techniques is considered being more effective with a higher successful rate. It is more preferable and recommended for clinical practice.
