摘要由于缺乏研究，部分义齿在功能上的确切行为尚未确定。也没有人知道牙医通过修改义齿设计可以影响力的分布和分散。本研究是在实验室条件下进行的，以确定部分义齿设计对基牙受力分布的影响。虽然测试情况与口腔中存在的情况不完全相同，但结果表明，牙齿的负载和移动受到诸如支托的数量和位置、连接体的轮廓和刚度以及义齿基托的延伸等因素的强烈影响。毫无疑问，其他可变因素，如功能基础，应力破坏，以及直接和间接固位体的应用，也同样重要。有必要沿着物理和生物两条线继续进行调查。它们最终将为义齿设计的发展提供信息，这些义齿设计与残留口腔结构的生理公差完全兼容。
Abstract Because of the lack of research studies, the exact behavior of partial dentures in function has not been determined. Neither has it been learned how much the distribution and dispersal of the force can be influenced by the dentist through modifications in denture design. The present studies were conducted under laboratory conditions to determine some of the effects of the design of partial dentures on the distribution of forces to the abutment teeth. Although the testing situations were not identical with those existing in the mouth, the results indicate that the loading and movement of the teeth are strongly influenced by such factors as the number and location of rests, contour and rigidity of connectors, and extension of denture bases. Undoubtedly other variable factors, such as functional basing, breaking of stress, and the application of direct and indirect retainers, are equally important for consideration. Continued investigations are necessary along both physical and biologic lines. They will yield information ultimately for the development of denture designs which are wholly compatible with the physiologic tolerances of the residual oral structures.
