ABSTRACT
In this work an advanced discretization meshless technique is applied to analyze the elastostatic behavior of implants inserted in the mandible bone. The natural neighbor radial point interpolation method (NNRPIM) is a flexible and efficient meshless method capable of predicting smooth and accurate stress fields. One of the advantages of meshless methods over the finite element method (FEM) is the complete freedom of the domain computational discretization, allowing to discretize biological structures with higher accuracy. In order to show the NNRPIM efficiency, two implant systems' numerical models are analyzed with the NNRPIM and the obtained results are compared with the FEM.
