Abstract

Basic principles of predicting the fatigue life of implants of various types made from titanium nick-elide-based alloys are determined. They include an analysis of the results of preliminary clinical tests for determining the change in the implant shape during the functional displacements of a patient, the calculation of the strain from the change in the implant shape, the determination of conditions for rapid fatigue tests of implants, and the prediction of the fatigue life of the implants using the results of rapid fatigue tests of the implant material.
