Evaluation of model parameters in teeth stress analysis

Finite element modelling is the commonly used methodology for the analysis of stress concentration within tooth components. The main limitation of the technique is oversimplifications are usually required due to the complex conditions at which oral structures operate. Therefore, the aim of this study is to examine how assumptions and modelling practices, related to the internal tooth structure, material properties and loading conditions, affect the mechanical response within dental models. This was achieved by developing a generalised mandibular first molar tooth model and by performing an in-silico parametric study.
