This case report involved the development of a rehabilitation system for patient with edentulism and an algorithm for diagnostic and therapeutic measures to be planned based on the patient's individual anatomical and physiological features. The results of treatment and rehabilitation made it possible to achieve the optimal distribution of loads on the dentition. It was shown that it is necessary to analyze casts in an articulator to reproduce a three-dimensional model of mandibular movements taking into account the individual features of the patient to obtain a satisfactory assessment and treatment planning of patients with edentulism requiring full mouth reconstruction. This case confirms that the developed algorithm is anatomically and pathogenetically justified, as it considers all changes and interrelationships of structures of the dentition. © 2020 Georg Thieme Verlag.
