Primary Research On Reconstruction And Application Of The Fine 3D Tooth Structure FEA Model

The Finite Element Method(FEM) is a powerful numerical technique to solve boundary value problems. A continuos domain is discretized to simple geometrical elements which are related to each other through nodal points. Application of the governing equations, loading and boundary conditions results in a system of equations which could be solved to find an approximate solution. Because finite element methods can be adapted to problems of great complexity and unusual geometry, they are an extremely powerful modern tool in biomechanics. It shows us great superiority and potential since introduced to the dentistry in 1973. And has been widely used in many different fields of oral biomechanics. The accuracy of the FEM results...
