摘要：研究间接粘接技术在正畸托槽粘连结中的强度。选取正畸患者共50例，需要1 000个托槽，随机分成A、B组，各组25名患者（500个托槽）;A组选择间接粘接技术，B组选择直接粘接技术，采用相同的方法进行粘接托槽，进行分析比较2个组在粘接后托槽的脱落率、粘结剂残留、抗剪切强度。结果表明：A组的脱落率小于B组，说明A组间接粘接法比B组直接粘接法牢固（P

Trength analysis of indirect bonding technique

in orthodontic bracket bondingXU Dan

（Department of Stomatology， Tangshan Hongci Hospital， Tangshan 063000， Hebei China）Abstract：To study the strength of indirect bonding technique in orthodontic bracket bonding， total of 50 orthodontic patients in Beijing Peoples Hospital who needed 1 000 brackets were selected and randomly divided into group A and group B with 25 patients （500 brackets） in each group. Indirect bonding technology was selected for group A， and direct bonding technology was selected for group B. The same bonding method was used for bonding brackets. The shedding rate， binder residue and shear strength of the brackets after bonding were compared between the two groups. Results show that the shedding rate of group A was lower than that of group B， indicating that indirect bonding method in group A was stronger than direct bonding method in group B， and the difference was statistically significant（P
