ОЦЕНКА ПЛОЩАДИ ОККЛЮЗИОННЫХ КОНТАКТОВ У ПАЦИЕНТОВ С ПАРАФУНКЦИЯМИ ЗУБОЧЕЛЮСТНОЙ СИСТЕМЫ ДО И ПОСЛЕ СПЛИНТ- ТЕРАПИИ С ПОМОЩЬЮ ЦИФРОВОГО АППАРАТА T-SCAN

Abstract

Abstract. Currently, dentists in the treatment of patients are increasingly encountering manifestations of parafunctions in the dental system. Most often, this manifests itself unconsciously in the form of daytime or nighttime bruxism and clenching. However, there is no reliable easily feasible method for diagnosing parafunctions. Digital dentistry is actively developing, which opens up new opportunities for assessing occlusive contacts. One of the most functional devices in this field is the T-scan. The aim of the study was to assess the area of facets of tooth erasure in patients with parafunctions before and after the use of occlusive splints using data from a digital T-scan device. In the study, occlusal contacts were registered, the sums of the facet areas of tooth erasure at the beginning of treatment and 6 months after splint therapy were calculated from the occlusiograms obtained. The results of the study showed that at the very beginning of the study, the values of the occlusal parameters of the right and left sides in patients in the group with bruxism and clenching prevail values of the left side of the dentition. The average sum of occlusal contact areas in patients with parafunctions was 310.02 mm2 on the left and 234 mm2 on the right. Upon repeated measurement, after splint therapy, the sum of the areas of occlusal contacts was 305.1 mm2 and 289.04 mm2 on the left and right, respectively. Thus, it is proved that the sum of the areas of occlusal contacts in patients on the left side of the dentition before the use of an occlusal splint significantly prevails over those after splint therapy. Occlusal forces between both sides of the lower jaw after the treatment have become more symmetrical and are close to a uniform distribution of force. This technique allows screening and monitoring of patients with bruxism and clenching.
