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.

Abstract
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.Pubblicazioni consigliate
