Abutment teeth have been treated as the elastic behavior at the supported conditions and apportionment loads are depended upon the elastic properties of the pontics and abutment teeth. So, this paper shows the apportionment loads of dental bridges and the dependence of the elastic constants of abutment teeth. Abutment teeth are rotated and sinked with digestive power on the pontics. So, the elastic constants of abutment teeth are given with k and K, which k, K are the sinked and rotated coefficients, which are expressed the elastic properties of these abutment teeth. Apportionment loads to be connected with the flexural rigidity of the pontics are calculated for two numerical examples (for the values of 3.6 x 10(3) kg-mm2 and 3.6 x 10(8) kg-mm2 of the concentrated and distributed loads).
基牙在支持条件下被视为具有弹性行为，分配载荷取决于桥体和基牙的弹性特性。因此，本文展示了牙桥的分配载荷以及基牙弹性常数的相关性。基牙会因作用于桥体上的咀嚼力而发生旋转和下沉。所以，基牙的弹性常数用k和K表示，其中k、K分别为下沉系数和旋转系数，它们体现了这些基牙的弹性特性。针对两个数值示例（集中载荷和分布载荷的值分别为3.6×10³ kg-mm² 和3.6×10⁸ kg-mm²），计算了与桥体抗弯刚度相关的分配载荷。
