A total of 100 working dies for fixed partial denture (FPD) abutments were prepared to fit 50 three-unit fixed-fixed conventional FPDs. For each FPD, the axial convergence angles between the mesial and distal axial walls of the abutment teeth were measured. For all FPDs, there were no statistically significant differences between the mesial and distal convergence angles of abutment teeth measured, regardless of their location within the oral cavity. The distal convergence angle of posterior FPD abutments was the highest angle, while the lowest was recorded for the mesial convergence angle of the anterior FPD abutments.
共制备了100个用于固定局部义齿（FPD）基牙的工作模型，以适配50个三单位固定-固定传统FPD。对于每个FPD，测量基牙近中壁和远中壁之间的轴向聚合角。对于所有FPD，无论其在口腔内的位置如何，所测量的基牙近中聚合角和远中聚合角之间均无统计学显著差异。后牙FPD基牙的远中聚合角最大，而前牙FPD基牙的近中聚合角最小。
