Description of finite element models, finite element mesh and boundary condition. A: Models A, B, and C. B - Model B with the removable partial denture (RPD). C: Model C with RPD and implant. Areas (1 to 6) selected to perform the analysis in all models. D:- The beam elements used to build the non-homogeneous periodontal ligament (PDL). E and F: Mesh refinements for tooth apex and implant, respectively. L shows the distributed loading scheme. The entire right and left sides were fixed on the x axis. The bone at the bottom of the model was fixed on the x and y axes
