[Simulation of stressed status of dental abutment tissues in normal and abnormal position of teeth]

Based on the final elements method, the authors simulated the stressed-deformed state of dental abutment tissues in normal and abnormal position of the teeth. The distribution of normal and tangent tensions in dental transverse sections and their contact interactions with the alveolar process (periodontium-periosteum) were studied. The effect of the inclination angle of abnormally positioned teeth in various force of occlusion was demonstrated and maximum values of this force were established from the strength viewpoint. The results confirm the efficiency of the proposed scheme for estimation of the stressed-deformed status of dental abutment teeth in practical orthodontics.
