Напряженное состояние резьбового соединения в системе дентальный имплантат – кость

Abstract

The distribution of load over a thread implant-bone joint has been studied. The thread joint is modeled by a rod structure in which an axial force is transferred from therod-implant to the stretched rod-bone through threads. The last ones are simulated by cantilever beams attached to the implant rods and bone. A closed-form differential equation describing the intensity of the axial force distribution is derived. The approach to solving a problem on distribution of the load over the thread joint of the implant with bone can be used as the basis to determining its stress state and improving the implant structure with an aim to increase service life of orthopedic constructions.
