Abstract

Evaluation of occlusal contacts in the lateral sections of the dentition is the daily task of a dentist engaged in restorative dentistry or orthodontic treatment. Many ways of registering occlusal-articulatory relationships of dentitions have been proposed, but most of them involve significant financial and time costs, which is difficult to implement at a routine appointment. The aim is clinical testing of an easily reproducible, informative method of index evaluation of occlusal contacts of dentition without the use of expensive equipment. >. 306 people with a formed dental system were examined. Criteria for inclusion in the study: age 18—29 years, complete dentition, orthognathic bite (orthognathic ratio) with bilateral first class according to Engl, absence of severe somatic diseases. Based on the survey of 306 people, we identified 4 groups depending on the etiological causes of primary occlusive injury. In the future, three main groups and a control group were formed in the same way, in which a full range of diagnostic and therapeutic measures were carried out. Thus, the I, II, and III main groups included 45, 32 and 41 patients, respectively, the control group consisted of 45 people without occlusive articulation disorders. The assessment of the state of the oral organs was carried out according to a generally accepted method, using a traditional set of dental instruments. We have developed and tested the method of index evaluation of occlusal contacts of lateral teeth “Method of index evaluation of occlusal contacts of lateral teeth” (patent for invention No. 2684182 dated 04.04.2019). >. The data of index evaluation of occlusal contacts of lateral teeth in patients of the main groups were obtained in comparison with similar data of patients of the control group. It was found that the differences between the occlusal index indices in the I, II and III groups for each of the index components (canines, premolars, molars) before treatment were not significant, but there was a statistically significant difference (p<0.05) between the occlusal index indices before treatment in patients of the main groups and the comparison group. In the latter, there was no need to correct the occlusal-articulatory relationship and the occlusal index was 1.98/10.84/19.27 for canines, premolars and molars, respectively. After the treatment measures carried out in patients of 3 main groups, a significant positive dynamics of the index assessment of occlusion was revealed. >. Monitoring of occlusal relationships using the “Method of index evaluation of occlusal contacts of lateral teeth” (patent for invention No. 2684182 dated 04.04.2019), in our opinion, should be carried out for patients of therapeutic, orthopedic and orthodontic profile before, during and after treatment, which will allow not only to digitally register the initial state of occlusion, but also conduct dynamic monitoring. This approach is of particular importance during the initial examination of young patients with complete dentitions, when it is possible to carry out a small amount of dental interventions aimed at preventing complex dental diseases.
