Abstract

In the last two decades, medical and engineering specialists developed a more and more close cooperation. Dental and orthodontic sciences represent an excellent example of this synergic view. In particular, detailed information on stress distribution in the implant region may greatly help clinical experts to reduce risk of failures thus preventing the need for re implantations. Of course, modeling and analysis of biological/medical structures is often based on subjective information that may considerably change from patient to patient. In view of this, the present research aims to set up a framework for building reliable analysis models from geometrical information gathered with medical imaging tools. In order to check the feasibility of the procedure, we considered the case of a human mandible for which a virtual model is reconstructed from Computerized Tomography. This case is very indicative because of the very high complexity of the anatomical district analyzed. The mandible model thus reconstructed has been studied with FEM analyses simulating four different scenarios that may occur during mastication. The experimental part of this research is the processing of CT scan files which actually requires a very accurate study and special cares. The experimental work then prosecuted with the construction of the a stereolithographic model that can be utilized for photoelastic investigations.
