摘　　要：目的探讨应用黏结型玻璃离子在埋伏牙正畸牵引中黏结正畸附件以提高黏结效率。方法选择2005年3月～2011年12月于我院口腔科行埋伏牙正畸牵引的患者46例（共有46颗黏结正畸牵拉附件埋伏牙），将46颗行闭合牵引助萌手术的埋伏牙分为两组，实验组应用黏结型玻璃离子黏结正畸牵拉附件，对照组常规使用牙釉质黏合树脂黏结牵拉附件，比较两组的首次黏结成功率和半月后正畸牵拉附件脱落率。结果首次黏结成功率：实验组为100％，对照组为52％。半月后脱落率：实验组为0％，对照组为25％。首次黏结成功率及半月后脱落率两组比较均有统计学意义（P〈0．01）。结论行闭合牵引助萌手术后的埋伏牙应常规应用黏结型玻璃离子黏结正畸牵拉附件，以提高黏结成功率和降低术后脱落率，避免二次手术。Objective To study the treatment for orthodontic traction of the impacted tooth with glass ionomer cement to improve adhesion efficiency. Methods A total of 46 orthodontic traction of the impacted tooth cases （46 bonded orthodontic attachments impacted teeth pulled） were selected from March 2005 to December 2012 with traction of impacted tooth in our hospital of stmatology department, 46 orthodontic patients were divided into two groups randomly. Following closed-eruption surgery. Experimental group were bonded with glass ionomer cement, the control group with enamel adhesive resin. Compared the failure rates for the first time and after half months. Results The success rate of the first bond, the experimental group was 100%, the control group was 52%. The expulsion rate after half months,0 for the experimental group, the control group was 25%. Initial success rate and after half months expulsion rates were significantly different between the two groups （P〈0.01）. Conclusion Impacted teeth should be routinely applied glass ionomer cement bonded orthodontic attachments to improve the success rate and reduce postoperative loss rate, to avoid the second surgery.
