Finite element models of dental titanium implants inserted in mandible region are
defined in order to evaluate the biomechanical response under the effect of different
loading types, such as masticatory or occlusal. The mechanical properties of bone tissue
surrounding dental titanium implants deeply influence the implant load carrying
capacity and must be carefully defined to obtain reliable numerical results. Anisotropic
configuration of the tissue and its limit strength in the transition region around the
implant must be evaluated, in order to estimate the response for the specific condition
considered. Assumptions made with regard to the properties of the tissue entails
different values of risk factor, showing the role of an effective definition of anisotropic
bone properties for numerical simulation of the functional response of dental implants
