The clinical techniques of the students were examined by analyzing the results of some measurements on the side wall inclination as a width and height of the full formed abutment of posterior fixed bridge, and the results of full covered crown data were compared. Significant differences in the inclination degree to the axis between upper and lower were not noticed in either premolars or molars on the mesio-distal side wall and bucco-lingual side wall, and were noticed between premolars and molars of the same jaw on both side walls. Margin diameter and height of diameter of the premolars showed a closer rank correlation than molars in mesio-distal side wall, but in bucco-lingual side wall, molars showed a closer rank correlation than premolars.
通过分析后牙固定桥全形基牙侧壁倾斜度（作为宽度和高度）的一些测量结果，对学生的临床技术进行了检查，并比较了全冠数据的结果。在前磨牙或磨牙的近远中侧壁和颊舌侧壁上，上下牙向轴的倾斜度均未发现显著差异，且在同一颌骨的前磨牙和磨牙之间的两个侧壁上均发现了差异。在前磨牙的近远中侧壁上，边缘直径和直径高度的等级相关性比磨牙更紧密，但在颊舌侧壁上，磨牙的等级相关性比前磨牙更紧密。
