摘　　要：目的:比较可拆卸式托盘和传统托盘对固定义齿制作的精度的影响。方法:在临床随机选取固定义齿修复的牙体缺损及牙列缺损病例,分别用新型可拆卸式托盘和传统托盘取模,灌注模型,双盲法制作固定义齿,粘接于模型上,高压水射流切割后测量粘接层厚度。结果:新型可拆卸式托盘组粘接层厚度小于传统组,两者差异有统计学意义(P<0.05),表征前者适合性好于后者。结论:采用新型可拆卸式托盘制作的固定义齿精度优于传统托盘,可作为临床新型托盘使用。Objective：Compare the effects of detachable and traditional pallet on the manufacture precision of fixed partial denture. Methods：Select clinical patients randomly,and make impression model with new detachable pallet and traditional pallet,perfuse the model,manufacture fixed partial denture in double-blind method and bond it to the model,then measure the thickness of bonding layers under somatotype microscope after incising it by high pressure water jet. Results：The thickness of bonding layer of new detachable pal-let is less than the traditional group,and there is a statistic difference between them （P〈0. 05）. The representation of suitability of the former is better than the latter. Conclusion：The fixed partial denture precision manufactured by new detachable pallet is better than the traditional. The new detachable pallet can be used as clinical new type of pallet.
