STUDY OF STABILITY OF OCCLUSAL BALANCE IN PATIENTS AFTER TOTAL RECONSTRUCTION OF TEETH OCCLUSION

Subject. The distribution of occlusal forces in the dentition (occlusal balance of the dentition). Objectives. To study the nature of changes in the distribution of occlusal forces in the sections of the dental arches in patients after a total reconstruction of the dentition using the developed method for assessing the occlusal balance of the dentition. Methodology. The study was carried out at the Department of Orthopedic Dentistry with a course of clinical dentistry at the Volgograd State Medical University (clinical base – Dental Polyclinic No. 3, Volgograd). The study involved 15 men and 17 women in need of a total reconstruction of the dentition. The mean age of participants in the clinical study was 33.4 ± 5.3 years. The occlusal balance was assessed on the basis of electronic occlusiography data according to the author's method. Stages of observation: before treatment; 2 weeks after fixing temporary dentures; the next day after the fixation of permanent prostheses; 6 months after prosthetics. Results. Before treatment, the indicators of the occlusal balance of the dentition in patients varied to a large extent depending on the presence of defects in the dentition, their location and extent. Fixation of temporary and then permanent dentures is accompanied by alignment of the occlusal balance of the dentition. 6 months after the total reconstruction of the dentition, there is a pronounced increase in occlusal imbalance in all parts of the dental arches, mainly on the right. Conclusions. The change in the occlusal balance after the total reconstruction of the dentition, which is a consequence of the changing tone of the muscles of the stomatognathic and postural systems in the process of their adaptation to the new position of the lower jaw, must be taken into account when organizing the monitoring of patients after orthopedic dental treatment in order to prevent post-prosthetic complications.
