The criteria for inclusion of patients in the study were the presence of a complete dentition and the absence of removed teeth in the upper jaw. A total of 50 patients participated in the study. Determination of the optimal zone for bone autograft sampling was carried out using cone-beam computed tomography (CBCT) of the upper jaw.Results: The optimal area for bone autograft sampling is the area of the palatine surface of the alveolar process in the projection of the frontal group of teeth and the area of the upper jaw mound. When taking bone autograft in he projection of the frontal group of teeth and the area of the upper jaw mound with a probability of 95.11%, a 4 mm long trepan can be used. In 39.6% of cases, the parameters of the alveolar process allow the use of standard trepans with a diameter of 3.5 mm, which makes it possible to obtain a bone cylinder with a diameter of 3 mm. At the same time, in the area of the alveolar process of the frontal group of teeth, it is possible to pick up bone autograft more by 16-23 mm3 than in the the area of the upper jaw mound.Conclusion: The palatine surface of the alveolar process can be used for bone autograft sampling when planning to eliminate limited defects of the upper jaw. The CBCT method makes it possible to determine the optimal bone autograft sampling zone and the available bone volume, which minimizes injury to the patient.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"102 5","pages":"40-49"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71486882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Criteria were proposed for comparing the results of AFM scanning of tooth enamel surface samples and, based on them, the nature of the main structural disorders of the enamel surface in the affected area was determined.Results: For all the samples studied, the healthy enamel surface was smoother compared to the enamel in the area of the clinically visible «white spot» and in the immediate vicinity of it. The heterogeneity of the enamel surface in the center of the white spot» for all the samples studied was at least 60% higher than at the edge of the process. It was revealed that the heterogeneity of the surface outside the clinically visible white spot at a distance of less than 1 mm from its perimeter is at least 30% higher than that of healthy tissue of the same tooth. It is shown that the heterogeneity of the enamel surface in the center of the caries area in the white spot stage is at least 4 times greater than the heterogeneity of the surface of the healthy enamel of the same tooth, which indicates its demineralization.Conclusion: The established features of the spread of the initial carious process can be used in clinical practice for the diagnosis and dynamic observation of the processes of enamel demineralization.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"102 5","pages":"20-26"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71486883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2007-2008, 354 implants were inserted in 27 patients. The age of the patients was 61.31±5.08 years. Mombelli index criteria (mBI [modified Sulcus Bleeding Index]) were used. The plaque index was determined using a modified Löe & Silness method. The state of the peri-implant bone (ΔMBL) was determined by a series of OPG. The Geriatric Oral Health Index (GOHAI) was used to assess oral health in the elderly.Results: Metal-ceramic full-arch implant prostheses with a gold-platinum alloy framework, based on a sufficient and optimal number of implants (6-8), showed high survival rate (100%) after 15 years. Marginal bone loss (ΔMBL) after 15 years was -1.44±1.27 mm. The survival rate of implants was 99.4%. Scores on the GOHAI scale were higher in patients after orthopedic rehabilitation (from 52.7±7.1 to 54.1±8.4, p<0.001).Conclusion: After 15 years, all prostheses had mechanical defects, which at the same time allowed them to be used without restrictions. Screw fixation of full-arch implant prostheses, although it was associated with mechanical complications, nevertheless made it possible to perform surgical interventions in a timely manner and stop the development of inflammatory complications. Thus, we do not see any grounds for removing metal-ceramic prostheses and replacing them with new implant prostheses even after a 15-year period of operation. At the same time, it is necessary to take into account the reduction in the possibility of individual oral hygiene in elderly patients, as well as possible restrictions on self-visiting a dentist or dental hygienist.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"102 6","pages":"22-27"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138300214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depending on the tactics of conservative treatment of CGP, patients were divided into two groups of 50 people.
