The aim of the study was to consider the contact interaction of a pair of opposing teeth with and without taking into account the three-layer mouthguard. The strain-stress analysis of the biomechanical model was undertaken within the framework of the elastoplastic stress-strain theory. 7 geometric configurations of the mouthguard were considered within a wide range of functional loads which were varied from 50 to 500 N. We obtained the distribution of the stress and strain intensities in a pair of opposing teeth during contact interaction at a different level of physiological load. The dependences of the maximum level of stress intensity and the intensity of plastic deformations in the biomechanical model were established. Contact parameters were considered near the zone of dental occlusion.
