Analisi BEM delle sollecitazioni a carico del nervo trigemino causate da impianti dentali multipli

In this work an elastic-static analysis is developed in order to assess how the masticatory loads, applied on a system of multiple independent implants in a mandible, are transferred to the trigeminal nerve. The simulation is based on the Boundary Element Method (BEM) and consider a perfect osteo-integration between implant and bone (continuity condition for traction and displacement at the implant-bone interface). The analysis considers the mandible segment containing two adjacent implants at different distances, each one loaded with a vertical load. Both the cortical and spongy bone are modeled as transversally isotropic. A non linear contact analysis is needed in order to properly model the nerve-canal interactions. The results obtained show the pressure on the trigeminal nerve against a varying distance between implants. Such information is useful for a correct surgical planning.
