Abstract
A significant problem of the temporo-mandibular joint (TMJ) research is lack of data concerning geometry and position of TMJ discs. It leads to necessity of developing a driving method of the process optimization, which is based on chosen techniques of mechatronic design. In particular, the latter concerns a technique of experimentally supported virtual prototyping. On this stage, the research is characterized by well-verified constitutive characteristics of all components, engagement of real components of the research system, offline experimental identification of the TMJ system parameters, offline experimental determination of the appropriate parameters of the TMJ, online computation of the TMJ process of non-stationary model and assessment of the driving method’s efficiency. In case of the medium opening–closing jaw motion, results of the FEM are close to the experimental data and validate discs’ geometries and positions. Quality of the obtained solution is also verified by analysing the contact between discs and surrounding bones. In case of the immediate clenching simulation, a comparison of finite element model simulation and dental plaster mould occlusions testifies the correctly reproduced occlusal scheme. Values of the contact forces and the contact area surfaces enable calculation of the mean contact pressure values on the cranial and caudal faces of the discs. The obtained model allowed reproducing accurate anatomic mandible trajectories and also a physical occlusion.
