The disc-shaped samples were polished and kept in dry conditions or distilled water (37 °C, 7 days). The Vickers hardness was measured on a Duramin-20 microhardness tester (load 25 g, exposure 15 s). Statistical processing is the Student's t-test.Results: In the dry state, all materials showed similar hardness (19-22 HV). The smallest decrease in hardness after water was observed in Huge PMMA (<7%) and Sinma-M (~3%). Dental Sand Pro showed a decrease of 12.4%. The maximum drop was in Tempocor (by 17%: from 19.72 to 16.37 HV). Microstructurally, Dental Sand Pro and Tempocor have pores and inhomogeneities.Conclusion: It is most stable in the aquatic environment of Huge PMMA (CAD/CAM). Sinma-M (hot polymerization) also demonstrates high stability. Dental Sand Pro 3D printing material requires optimization of post-polymerization modes. Tempocor (cold curing) is the least water-resistant, and its use for long-term temporary restoration is limited. Surface hardness is an informative criterion for preclinical assessment of the reliability of temporary restorations.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 5","pages":"13-18"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246607","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}

Patients were divided into 2 groups: group 1 (n=9) and group 2 (n=7). Treatment involved surgical correction of gingival recession using a connective tissue graft. In group 1, the guided bone regeneration (GBR) technique with soft tissue plastic surgery was applied. In group 2, a modified coronally advanced flap (CAF) was used. Assessment methods included periodontal probing, intraoral scanning (TRIOS 3Shape), cone-beam computed tomography (CBCT), and photography.Results: In group 1, the mean percentage of gingival recession coverage was 95%, compared to 87% in group 2.

At the beginning of the study, rabbits from the experimental group underwent multiple measurements of the velocity of the ultrasound broadband complex-modulated \"split\" signal were carried out by coaxially fixed conical separate-combined piezoelectric transducers (PET) with a working part of the conical lenses of 1 mm and with adaptive acoustic cuffs. From each anatomical zone, measurements were obtained in the amount of n=30.

Forty implants were divided in two groups which included 10 implants of each type according to thread design. In the first group bone site preparation was conducted with spiral drills, in the second one - using stepped drill. Peek torque values were measured with surgical motor and dynamometric key and to assess implant stability quotient was used Osstell device with Smartpeg and Multipeg pins.Results: In the first group, there was no significant difference using any type of implant. In the second group, there was a significant increase in the studied parameters during the use of implants with «active» threads with a stepped drill. Torque values increased in 1.7 times. The increase in stability quotient for both Smartpeg and Multipeg pins in average was 8% and 7% respectively. When comparing cylindrical implants with non-aggressive threads with standard drills and conical implants with «active» threads with a stepped drill, the increase of maximum torque and stability quotient was 80%, 8% and 7% respectively.Conclusion: The use of cylindrical implants with non-aggressive threads when working in low density bone both when using spiral or stepped drills, is characterized by low values of torque and stability quotient.

The assessment of the development of 22 clinical and pedagogically justified practical skills by 5-year students, covering the key sections of periodontology, was carried out. The performance of each student's practical skills was evaluated by expert teachers using a special standardized checklist based on the principles of the Objective Structured Clinical Examination (OSCE) using a 5-point scale. An integral complexity index (ICI) was calculated, combining objective and subjective data.Results: The average expert ratings of the performance of the acquired skills ranged from 3.3 to 4.5 points (out of 5), while the average self-ratings of the difficulty of performing the same skills by students ranged from 3.0 to 4.5 points (where 5 means \"very difficult\"). The calculated indices of skill difficulty ranged from 0.71 to 0.88, which reflects a more pronounced differentiation in the level of difficulty of practical manipulations. Skills are stratified by IC: simple (IC ≤0.72), medium complexity (0.73-0.80), and complex (IC ≥0.81).Conclusion: The proposed complexity index allows for the optimization of training programs, focusing on the most difficult manipulations.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 5","pages":"77-81"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246570","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}

These drugs affect bone tissue, suppress the osteoclasts activity and, indirectly, osteoblasts, slowing down mineral metabolism in general. Denosumab is a monoclonal antibody against RANKL that blocks the differentiation and activation of osteoclasts. Despite their effectiveness in preventing bone loss, both classes of drugs can cause osteonecrosis of the jaw. The direct mechanisms of osteonecrosis are not completely understood, but it is believed that this process is associated with the suppression of bone remodeling, deterioration of bone trophism, and the microbial-induced inflammation, which is facilitated by the action of antiresorptive drugs. In addition to physical examination and X-ray imaging, various methods based on the effect of fluorescence are used for the precise visualization of necrotic tissue. Osteonecrosis is treated conservatively or surgically, depending on the stage of the disease. Understanding the mechanisms and specific morphological features of MRONJ is necessary to optimize treatment strategy and minimize possible complications.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 5","pages":"95-98"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246709","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}
