A special questionnaire for gathering information about the psycho-emotional status, pathogenetic factors and the clinical picture of dental hard tissues abrasion was developed, which allows to assess the severity of symptoms, the presence, severity and risks of disease progression in patients. The occlusal table was modified to determine the position of the occlusal plane in three mutually perpendicular planes, which is important for the full analysis of occlusion and optimization of the occlusal surface of dentures. The technique of computer calculation of the areas of occlusive contacts, registered with the help of clinical and digital control of occlusion of teeth, which contributes to the efficiency of dental rehabilitation measures, is developed.
