Fatigue algorithm for dental implant

Restorations with the application of implants are effective and commonly used in dental treatment. The computer simulation of implant fatigue life employing FEA is considered in the paper. For the simulation of implant structure behavior a 3D model including a spiral thread is applied, which allows for the full simulation of the kinematics of the implant, describing the multiaxial state of stress and, in consequence, the possibility of screw loosening. The cyclic scheme of the physiological occlusal loading and fatigue changes of dental material, bone loss phenomenon and changeability of boundary conditions are investigated. The valuable results for fatigue life which may be applied in modern prosthodontics are presented.
