The example represented in Fig. 1 shows the response of a threaded cylindrical implant in case of detachment between bone and implant surface. Different elastic properties are assumed for the cortical and trabecular bone. Different values of the Young's modulus are assumed in the periimplant bone region. In particular, the Young's modulus is set at 0.6 GPa. A gap is considered at the level of the bone-implant interface to simulate the poor mechanical properties of the material surrounding the implant. An intrusive force of 200 N and a transversal force of 20 N are applied to the implant. Yellow arrows show the direction of intrusive and vertical force. The magnitude displacements field on a section of the mandible is shown, highlithing compression regions (red arrows) and tension regions (green arrows) of bone.
