摘要： 目的比较双层透明压膜片法间接粘结托槽时, 使用全牙弓转移托盘及分段牙弓转移托盘所耗时间及粘结效果,为临床提供参考。方法选择45例正畸固定矫治病例,根据粘结方法及转移托盘不同随机分为3组,每组15例,共计270个托槽,120个颊管。A、B组均使用双层透明压膜片法间接粘结托槽,其中A组为全牙弓托盘,B组为分段牙弓托盘,C组为直接粘结托槽。后牙垫高以咬合时不影响下颌托槽为准。记录A、B组口外托槽粘结耗时T1（口外托槽定位粘结及光固化结束）,转移托盘制作时间T2（从压膜开始到转移托盘制作结束备用）,A、B、C各组平均椅旁时间T3（从口内开始酸蚀到口内托槽全部粘结固化结束）,比较A、B组各阶段耗时及 A、B、C各组即刻托槽脱落率及即刻颊管脱落率。采用SPSS 22.0软件包对数据进行统计学分析。结果经均值方程t检验,A、B 2组的T1及T3 之间无显著差异（P均>0.05）。A、B 2组T2比较,A组显著小于B组（P<0.05）,A、B、C 3组间颊管即刻脱落情况及托槽即刻脱落情况为A组显著大于B、C组,各组间差异显著（P<0.05）。结论双层透明压膜片法粘结托槽简单便捷,分段牙弓转移托盘较全牙弓转移托盘耗时多,但托槽即刻脱落率较低。

Abstract: PURPOSE: To compare the time-consuming and bonding effectiveness of full dental arch and segmented dental arch, when double transparent pressure diaphragm technology was used for indirect bracket bonding. METHODS： Forty-five orthodontic cases were selected, and classified into 3 groups according to different bonding methods and arches. There were 15 cases in each group, a total of 270 brackets and 120 buccal tubes were used. Patients in group A and B received double transparent pressure diaphragm technology to bond brackets indirectly. Among them, full dental arch tray was applied in group A, segmented dental arch tray was applied in group B; the brackets was bonded directly in group C. High posterior teeth pad did not affect the mandibular bracket during occlusion. The amount of time to bond brackets in group A and B (started from brackets bonding to the end of light-cure) was recorded as T1, the time of making arches was recorded as T2 (started from pressed film to the end of the arches made) and the average chair-side time of group A, B and C (started from acid etching in the mouth until all brackets are finished bonding and curing). Time-consuming of each stage in group A, B, immediate bracket failure rate and immediate buccal tube failure rate in group A, B, C were compared. SPSS 22.0 software package was used for statistical analysis. RESULTS: There was no significant difference in T1 and T2 between group A and B (P>0.05). T2 in group A was significantly less than in group B (P<0.05). Immediate buccal tube and braces failure rate in group A was significantly greater than in group B and C. CONCLUSIONS: Using double transparent pressure diaphragm technology to bond bracket indirectly is convenient and simple. The segmented dental arch is more time-consuming compared to full dental arch. However, the immediate bracket failure rate is lower.
