METHOD FOR INDEX DIAGNOSTICS OF CHANGES IN OCCLUSAL SURFACES OF TEETH AND SEVERITY OF IATROGENIC FACTOR ON CHANGE IN FUNCTIONING OF STRUCTURAL COMPONENTS OF MAXILLOFACIAL REGION

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to the field of dentistry, and can be used for therapeutic and orthopedic treatment of individual teeth of patients, for replacing dentition defects in total reconstruction of occlusal relationships during prosthetics in dental and orthopedic hospitals. The occlusal contacts are marked with articulating paper with the designation of the contact points on the teeth and artificial tooth surfaces. After marking, photographing of the dentition is carried out with the determination of the presence or absence of points of statistical and dynamic contacts on artificially created surfaces of the teeth, while the marking of occlusal contacts is performed using articulation paper 40 microns thick in blue, 8 microns thick in red and 8 microns thick in green. in this case, the contact visualized on the patient's dental surface, characterized by a blue area with a red dot inside, is schematically denoted as static contact with an increasing density to the center of the red contact point, and the contact visualized on the patient's dental surface, characterized by a green dot, is schematically designated as dynamic contact. After photographing the dentition of the patient's lower and upper jaws and converting the resulting images into digital form, an analytical identification of teeth is performed, on which static and dynamic contacts are detected on teeth with artificially created surfaces as a result of orthopedic and therapeutic interventions in the form of various types of crowns, onlays, veneers, etc. sealed surfaces. According to the results of the performed analytical analysis, the surface of the tooth, on which the occlusal contacts are located on an artificially created area, is taken as a unit without considering the presence of contacts on the own tissues of the tooth, and orthopedic structures on the teeth, missing and restored teeth by crowns or bridges are also taken for a tooth with a modified anatomical surface in case of occlusal contacts. At the same time, according to the results of the analysis performed, the total number of teeth participating in the occlusal-articulatory relationship is determined, while the total number of teeth does not consider the teeth on which there are no occlusal contacts and which do not affect the occlusal-articulatory relationship. Then the index of changes in occlusal surfaces is calculated as the ratio of the number of teeth with a changed anatomical surface to the number of teeth participating in the occlusal-articulation relationship. At the same time, when the value of the index of changes in the occlusal surfaces is established in the range from 0 to 0.14, a mild degree of the index of changes in the occlusal surfaces is diagnosed, which indicates a lesser degree of iatrogenic intervention and, accordingly, a more natural functioning of the occlusion, when the value of the index of changes in occlusal surfaces is established in the range from 0.15 to 0.5, the average degree of the index of changes in occlusal surfaces is diagnosed, which indicates an average degree of iatrogenic intervention and, accordingly, less natural functioning of the occlusion, when the value of the index of changes in occlusal surfaces is established in the range from 0.15 to 0.5, the average degree of the index of changes in occlusal surfaces is diagnosed, which indicates an average degree of iatrogenic intervention and, accordingly, less natural functioning of the occlusion, when the value of the index of changes in occlusal surfaces is established in the range from 0.51 to 1.0, a significantly pronounced degree of the index of changes in occlusal surfaces is diagnosed, which indicates a significant degree of iatrogenic intervention and, accordingly, an unnatural functioning of the occlusion.;EFFECT: invention allows quantitatively assessing the degree of iatrogenic intervention in a patient, drawing conclusions about the need for additional instrumental examination methods and the degree of risk of pathology from uncontrolled intervention.;1 cl, 3 ex
