Abstract
Finite element method (FEM) is an important tool used in our days even in medicine was the relationship between the human body and artificial structure can be predicted. This work presents a numerical study performed with FEM of new dental implant system. A conventional dental implant system was redesigned and an artificial periodontal ligament was interposed between the implant and the alveolar bone. The aim was to attenuate the stress in the bone surrounding the implant. The new system was assessed and the interface stresses compared with the ones provoked by the conventional implant. In general, the novel dental implant provoked lower interface stresses due to the stress shielding effect of the artificial periodontal ligament.
