The long-term goal of this thesis is to develop a tool to assist in the surgical planning of lingual surgery. This tool is based on a 3D biomechanical model of the tongue allowing to evaluate the functional consequences of a surgery on the lingual mobility. Our work attempts to lay the theoretical and methodological foundations for the creation of such a tool.
The first part of this thesis was devoted to the creation of a 3D biomechanical finite element (FE) model of the oral cavity. This model has a refined and converged mesh and a precise definition of the anatomical structures leading to more realistic and quality simulations.
The second part of the thesis focuses on obtaining a clinician-usable model of the language in interactive time using model reduction methods. The results of a model reduction method "DRB" based on machine learning applied to our 3D biomechanical model of the human tongue.
The last part consists of preliminary work concerning the creation of a prototype of pre-operative simulator.
