目的：评价锥形束CT（ CBCT）和光固化粘接技术在上颌埋伏前牙正畸矫治中的应用效果。方法选择2006年3月-2012年10月在我院正畸科诊治的上前牙埋伏阻生患者28例，根据患者埋伏阻生牙检查定位方法分为传统X线片组和CBCT组，传统X线片组采用37％磷酸酸蚀剂和津京牙釉质粘接剂严格按照使用说明进行埋伏牙托槽的直接粘接和脱落后再粘接；CBCT 组采用3M公司生产的TransbondTM PLUS MIP耐湿性处理液和TransbondTM PLUS光固化粘接剂严格按照使用说明进行托槽的直接粘接和脱落后再粘接。分别记录2组患者埋伏牙牵引至正常位置所需时间及牵引过程中埋伏牙托槽的脱落情况，比较其差异。结果 CBCT组埋伏牙托槽脱落次数及矫治时间均少于传统X线片组（ P＜0．05）。结论 CBCT和光固化粘接技术的结合在上颌前部埋伏阻生牙的正畸矫治过程中发挥了积极有效的作用。

Objective To analyze the clinical use of CBCT and light cure adhesive system in treatment of anterior maxil -lary impacted teeth in orthodontics .Methods Patients with impacted teeth were divided into two groups according to methods of examination .Brackets of traditional X-ray group were bonded and rebonded with Tianjin-Beijing enamel adhesive system while brackets of CBCT group with Transbond TM PLUS MIP and Transbond TM PLUS light cure adhesive system .Treatment dura-tion and rates of bond failure of the two groups were collected and analyzed .Results For the traditional X-ray group,the fail-ure rate was higher(P<0.05)and the treatment duration was longer (P<0.05) than that of the CBCT group.Conclusion The clinical use of CBCT and light cure adhesive system is of great value in the orthodontic treatment of anterior maxillary im -pacted teeth .
