ABSTRACT

In this study, a new surgical technique for the insertion of implants in atrophic maxilla (4-On-Pillars) was numerically analysed, using the Finite Element Method (FEM) and a meshless method—the Radial Point Interpolation Method (RPIM). Based on anonymized radiographs, a 2D model was constructed. In order to simulate the surrounding structural environment, natural and essential boundary conditions were calculated and imposed into the model. The results showed distinct stress distribution for the two methods used. It was possible to observe that meshless methods produce smoother stress distribution when compared to FEM.
