Clinical example of predicting the time of using Ni-Ti machine tools

Abstract

Endodontic treatment of root canals of teeth is always a very complex and long process, which requires the dentist not only practical training, but also the search for new techniques and technologies. As is known, instrumental treatment of root canals of teeth is very often accompanied by a complication in the form of fracture of endodontic instrument. We performed endodontic treatment with prediction of time of safe use of nickel-titanium instruments. In the course of our investigation we used the computer program ANSYS and the virtual model of Ni-Ti instruments as well as graph of the behaviour of Nickel-titanium alloy in terms of mechanical loads. Analyzing the results of clinical trials of endodontic instruments such as Profile, it was predicted his work from the beginning of deformation to fracture, depending on the amount of stress that occurs in the structure of the alloy tool.
