Dental FEA consists in a dental application of finite element analysis. The dental prosthesis area can be identified and pointed out with the highest stress generated allowing the technical analyst to riduce or eliminate it by varying dental prosthesis morphology and thickness and improving material characteristics. This way an optimal prosthesis can be realized without iatrogenic damage, in particular in complex implant projects. An FEM model of the dental prosthesis has been developed taking into account shape and material characteristics of the different parts of the prosthesis. The model was developed starting from patient specific raw data and CAD representations. A FEM linear static analysis has been carried out in order to compute stress and displacements on specific contact tooth areas and connecting parts of the project. Boundary conditions and loads have been defined and applied following an at present normally used patient specific simulation in personal medicine, with a reproduceable accuracy of contact bite areas and vectorial loads from meta analysis and statistical-experimental values. More realistic load values in the contact bite areas could be experimentally measured and acquired by means of on purpose designed load cells and assigned patient test conditions in a near future for a better FEM simulation results validation. The aim of the study here presented would be that of showing the capabilities of a convincing medical and technical methodology in order to develop a dental prosthesis forecast model and a simulation tool with state-of-the-art acceptable validation. This method could be open and shared with European Community experties by means of a cross fertilization idea in International and interdisciplinary community. This new predictive approach in the medical field seems interesting as patient specific with advances in prevention, diagnosis and therapy of a lot of pathologies in personal dental medicine, surgical planning and medical device design.

Abstract
Dental FEA consists in a dental application of finite element analysis. The dental prosthesis area can be identified and pointed out with the highest stress generated allowing the technical analyst to riduce or eliminate it by varying dental prosthesis morphology and thickness and improving material characteristics. This way an optimal prosthesis can be realized without iatrogenic damage, in particular in complex implant projects. An FEM model of the dental prosthesis has been developed taking into account shape and material characteristics of the different parts of the prosthesis. The model was developed starting from patient specific raw data and CAD representations. A FEM linear static analysis has been carried out in order to compute stress and displacements on specific contact tooth areas and connecting parts of the project. Boundary conditions and loads have been defined and applied following an at present normally used patient specific simulation in personal medicine, with a reproduceable accuracy of contact bite areas and vectorial loads from meta analysis and statistical-experimental values. More realistic load values in the contact bite areas could be experimentally measured and acquired by means of on purpose designed load cells and assigned patient test conditions in a near future for a better FEM simulation results validation. The aim of the study here presented would be that of showing the capabilities of a convincing medical and technical methodology in order to develop a dental prosthesis forecast model and a simulation tool with state-of-the-art acceptable validation. This method could be open and shared with European Community experties by means of a cross fertilization idea in International and interdisciplinary community. This new predictive approach in the medical field seems interesting as patient specific with advances in prevention, diagnosis and therapy of a lot of pathologies in personal dental medicine, surgical planning and medical device design. Orthodontic and maxillo facial applications could also be improved by means of dental FEA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
