Analytical Assessment of Fatigue Strength of a Dental Crown

Abstract

With the accomplishment of new engineering science and technologies, machineries formulated by the the technocrats are utilized in medical field. Biomedical Engineering has thus gained a prominent status in the recent years. Few decades ago, it was considered as weird thing if any mechanical engineers performed studies on dental area, but in today’s scenario mechanical engineers are doing studies as well as research in the area of dental science. In this paper an attempt has been made to select best crown material for molar tooth, So that an appropriate material can be placed in the human body which is most difficult task .so for designing a molar crown, modeling is done in pro/engineer software, it is one of the parametric 3D CAD/CAM/CAE solution widely used by mechanical engineers for designing any product .this software creates a complete 3D Digital model of the product. For this extensive research, design for all crowns will be the same but only material properties will be different. After design, failure analysis is done. Loss of ability to function normally is the study of failure analysis. This is accomplished by considering various loading conditions .Here finite element analysis is used, the standard principle underlying the FEM are simple. The word finite is used to describe the limited, or finite, number of degrees of freedom used to model the behavior of each element, the element are assumed to be connected to one another but only at interconnected joints, known as nodes. Considering a body through which the distribution of a field variable I.e. displacement or stress is required, this body could be subjected to various loads. Problem is solved by two methods: static fatigue and dynamic fatigue
