The aim of this study was to analyse stress distribution in feline tooth during occlusal loading in order to accept or reject the hypothesis that dental resorptive lesions in cats might be caused by occlusal trauma. A solid model of feline tooth had to be created in order to perform the investigation. The idea was to gain data for tooth displacement (deformation) and stress and strain distribution under loading generally for any feline tooth using the finite element method. The results of the study contribute to the theory that occlusal overload might be one of the causes in multifactorial resorptive lesions in cats. Succession of tensile and compressive stresses and tooth displacement during occlusal loading might be a contributive factor in the pathogenesis of feline resorptive lesions. However, further research is required to confirm this statement.
