随机选择６０名无牙患者，各制作两副全口义齿，分别采用圆形曲面板排牙和平面板排牙，在其他相关条件一致的前提下进行自身对照和双盲法检验，本文报告了实验方法及其设计原理，比较了两法排牙义齿的正中平衡效果。通过正中咬合印数的多少及两侧印对称性观察，显示两法排牙具有显著性差异（Ｐ＜０．００１），说明圆形曲面板排牙法的正中平衡效果优于平面板排牙法。 Sixty toothless patients were randomly selected, and two complete dentures were made. Self-control and double-blind test were performed under the same conditions as other related conditions, using circular curved plate row teeth and flat plate row teeth respectively. This paper reports the experiment Method and its design principle, the median balance between two denture dentures was compared. Through the number of median bite print and impression of symmetry on both sides, it shows that there is significant difference between the two methods (P <0.001), which shows that the center balance effect of circular curved plate rowing method is better than that of flat plate rowing law.
