Abstrakt:	The load distribution over the turns of an implant–bone threaded joint is studied. Such a joint is modeled by a rod structure in which the functional axial force is transferred from the compressed-rod–implant system to the stretched-rod–bone system through thread turns. The turns are modeled by cantilever beams attached to the implant and bone rods. Differential equation describing the intensity of distribution of the axial force is derived in a closed form. The proposed approach to determining the distribution of the load over the thread of the implant–bone joint can be used to determine the stress state of the joint, improve its design, and increase the service life of dental prostheses.
