[Peculiarities of stapes functioning in the patients presenting with otosclerosis from the standpoint of biomechanical modeling].

The objective of the present study was to elucidate, in the framework of a biomechanical model, the biomechanical prerequisites for the development of osteodystrophic changes in stirrup bones in the case of their osteodystrophic fixation. The comparative analysis of the biomechanical models of mobile and ankylotic stapes demonstrated that the mild enough strain-stress state under the normal conditions turns into the rigid state in otosclerosis. The main dampher in case of load application to the adequately mobile stapes footplates is the round ligament.

[Biomechanical fundamentals of the dentofacial anomalies treatment].

The results of biomechanical investigations of the central incisor having the formed root by mathematical modeling methods are presented. The centre of resistance of a tooth, the optimal horizontal forces of action and reaction were determined. The advantage of discontinuous forces due to amortization influence of periodontal ligament fluid was biomechanically proven.

[Biomechanical problems of the maxillodental system in children].

The biomechanical regularities of the function of anatomic blocks of the maxillodental system were studied using mathematical simulation and mathematical models. The biological concept of the structure and biomechanics of human masticatory system is presented. Methods of rapid diagnosis, based on the anthropometric characteristics of the face, and a mathematical model of the function of the maxillodental system intended for the orthodontic treatment of maxillodental abnormalities in children have been developed.
