For the full-fledged work of a dentist-implantologist working in the field of replenishment of dentition with the help of dental implants and prostheses based on them in the modern realities of excessive variability of implant systems and suprastructures for them, the clinician needs to understand the criteria that various structural elements must meet, regardless of whether the structure is a single tooth, a bridge, or a full dentition restored with the above structure. In accordance with modern scientific concepts, the long-term survival of implants and teeth restored with their help is influenced by various mechanical and biological factors, such as: switching platforms, the type of connection of the abutment to the implant body, including the cone, its angle, internal or external polyhedron, the type and shape of the thread, the coating of the screw fixing the superstructure to the shaft of the dental implant (DI), the condition of the soft tissues and other factors disclosed in this article. The article will be useful for dentists involved in the restoration of dentition using various types of prostheses based on DI to become familiar with modern trends and scientifically proven facts about various elements of the implant-prosthesis complex. The article will also be useful for the clinician to select an implantological system that meets modern criteria of reliability and efficiency among the many variations presented on the medical device market. The team of authors recommends that the article be read by senior students and residents studying at the dental faculties of medical universities for a deeper understanding of the conditions that in the near future they will have to take into account when following the path of an orthopedic dentist or dental surgeon.
在种植体系统和种植体上部结构千变万化的现代社会中，牙科医生-种植体学家要想在借助种植体和以种植体为基础的义齿修复领域全面开展工作，就必须了解各种结构元素必须满足的标准，无论该结构是单颗牙齿、牙桥，还是用上述结构修复的全口牙齿。根据现代科学理念，种植体和在其帮助下修复的牙齿的长期存活受到各种机械和生物因素的影响，例如：转换平台、基台与种植体的连接类型，包括锥体、其角度、内部或外部多面体、螺纹的类型和形状、将上部结构固定在牙科种植体轴上的螺钉（DI）的涂层、软组织的状况以及本文披露的其他因素。这篇文章将有助于牙医在使用基于 DI 的各种修复体修复牙齿时熟悉现代趋势和有关种植体-修复体复合体各种要素的科学事实。这篇文章还有助于临床医生从医疗器械市场上的众多产品中选择符合现代可靠性和效率标准的种植系统。作者团队建议在医科大学牙科学院学习的高年级学生和住院医师阅读这篇文章，以便更深入地了解在不久的将来，他们在成为矫形牙医或牙科医生时必须考虑的条件。

Importance Currently, the prevalence of various diseases of the oral mucosa in the world has increased significantly (from 15.2% to 49.1%). Oncological pathology should be attributed to a separate group of diseases. In order to actively identify precancerous processes of the oral cavity, along with traditional methods of examination of the maxillofacial region, oncoscreening of the mucous membrane and organs of the oral cavity is mandatory. One of the possible methods of oncoscreening is autofluorescence stomatoscopy. Objectives To clarify the effectiveness of autofluorescence stomatoscopy as the main method of early diagnosis of precancerous diseases of the oral mucosa, its advantages and disadvantages. Methods In the process of investigating the effectiveness of autofluorescence stomatoscopy, methods of qualitative analysis and synthesis of available scientific literature on autofluorescence stomatoscopy were used. Conclusions It is concluded that the use of autofluorescence stomatoscopy for the early diagnosis of precancerous diseases of the oral mucosa remains controversial. Some clinicians believe that the introduction of autofluorescence stomatoscopy into the practice of a dentist as an additional method of oncoscreening of the oral mucosa is not only relevant, but also necessary; and the analysis of the light glow corresponds to the results of a biopsy. However, other researchers have concluded that the AFS-method will not replace the gold standard of histological examination, due to the low specificity of the method, the study can lead to overdiagnosis, and it can only be used by experienced clinicians to find the boundaries of precancerous lesions of the oral cavity for taking a biopsy in an altered mucous membrane.

The article is devoted to the analysis of the volume of dental orthopedic care for patients in the system of paid medical services in a multidisciplinary medical organization. Various epidemiological surveys conducted abroad and in our country have revealed an unsatisfactory condition of the organs and tissues of the mouth in the majority of the Russian population. Among dental pathology, tooth loss with subsequent functional disorders occupies a significant place [2–4]. One of the important indicators of dental health of the adult population, characterizing the level of dental care, is to ensure the need for prosthetics. According to WHO, the main causes of missing teeth are periodontitis and caries. Periodontitis is noted in 75–80% of the population, of which 90% are elderly and senile people. According to A. K. Kuryanov and L. N. Babenko (1988), 75% of 1,000 examined at the age of 60 needed dental prosthetics, and complete loss of teeth in the jaw was detected in 225 cases [1]. An analysis of the volume of dental orthopedic care for patients in the provision of paid medical services in orthopedic dentistry showed that for 5 years, among all manufactured orthopedic structures, removable plate prostheses with partial absence of teeth accounted for the largest volume, single crowns in second place, removable plate prostheses in the third place with complete absence of teeth. For each type of orthopedic structures manufactured, there is a growth trend from 2018 to 2022. There was a slight decrease in the volume of orthopedic dental care in 2020, due to the unfavorable epidemiological situation in the country at that time.
本文专门分析了在多学科医疗机构的有偿医疗服务体系中为患者提供的牙科矫形治疗量。国外和国内进行的各种流行病学调查显示，大多数俄罗斯人的口腔器官和组织状况不尽人意。在牙科病理学中，牙齿脱落和随之而来的功能障碍占有重要地位 [2-4]。成年人牙齿健康的重要指标之一是确保修复需求，这也是牙齿保健水平的特征。根据世界卫生组织的资料，造成牙齿缺失的主要原因是牙周炎和龋齿。75-80% 的人口患有牙周炎，其中 90% 是老人和老年人。根据 A. K. Kuryanov 和 L. N. Babenko（1988 年）的研究，在 1 000 名 60 岁的受检者中，有 75% 的人需要进行牙齿修复，其中 225 例发现下颌牙齿完全缺失 [1]。在牙科矫形有偿医疗服务中，对患者牙科矫形治疗量的分析表明，5 年来，在所有制造的矫形结构中，部分缺牙的活动板式义齿数量最多，单冠位居第二，完全缺牙的活动板式义齿位居第三。从 2018 年到 2022 年，生产的每一类矫形结构都呈增长趋势。2020 年，牙科矫形的数量略有下降，原因是当时国内的流行病状况不佳。

Objective. To improve technically the diagnostic analysis of 3D-cephalometric parameters of the skull and 3D-odontometric and 3D-biometric parameters of the complete dentition with distal occlusion during the period of permanent dentition according to extended cone-beam computed tomography. Methodology. 134 patients aged 17–35 years with a “distal occlusion” diagnosis were 3D-cephalometrically and 3D-biometrically examined.The parameters of the tragus width and diagonal of the skull on both sides were studied using virtual dynamic 3D-reformats of the skull. The gnathic skull index was calculated and the mesognathic, dolichognathic and brachygnathic skull types were determined. The width, thickness and height of permanent teeth crowns were measured using virtual dynamic 3D-reformats of diagnostic jaw models. Dental types (normodont, microdont, macrodont) of the complete dentition with distal occlusion were determined and abnormal forms (V-shaped, saddle-shaped, triangular, trapezoid, asymmetric) of dentition were pictured. The arcade index was calculated and gnathic types (mesognathic, dolichgnathic, brachiagnathic) of dentition were determined. Severity of the sagittal occlusal curve of Spee was determined on both sides. Results. Mesognathic and dolichognathic types of skull were diagnosed most often; the brachygnathic type was the least common. The combined dental type was in the lead, followed by the microdont and normodont types, the macrodont type was the least common among the dental types of dentition. Analysis of the abnormal shapes of dentition showed a trapezoidal shape predominance in both jaws. The dolichognathic type was most often to be found smong the gnathic types of dentition on both jaws. When analyzing the severity of sagittal occlusal Spee curves, the sharply concave curve was the leader on both sides. Conclusion. Individual 3D-cephalometric and 3D-biometric parameters obtained from extended cone-beam computed tomography can be used to simplify diagnosis, prognosis and to improve the effectiveness of orthodontic treatment.

Periodontitis is the most common inflammatory disease that leads to the destruction of the supporting tissues of the tooth. Therapeutic treatments aimed at reducing the effects of matrix metalloproteinases (MMPs) may be an effective adjunct to the treatment of periodontitis. The review examines the role of proteolytic enzyme inhibitors in the treatment of inflammatory periodontal diseases. General information about the ability of tetracyclines to inhibit MMPs is discussed. The purpose of the study was to examine the use of MMP inhibitors as a treatment for periodontal disease. Material and research methods. A scientific review of studies was carried out in Russian and English using information portals and platforms eLIBRARY.ru, Web of Science, PubMed and Scopus. The search was carried out using the following keywords: matrix metalloproteinases; oral diseases; tissue inhibitors of metalloproteinases. Of the 55 initially identified articles, after the initial analysis, 19 publications devoted to the study of MMP inhibitors associated with periodontal diseases were selected. Results of the study. Analysis of the literature allows us to conclude that the elimination of local irritants of periodontal tissues, the use of a therapeutic and prophylactic complex of measures using MMP inhibitors will have an advantage over traditional methods of treatment, will contribute to longer remission and prevent the progression of the inflammatory process in periodontal tissues, positively influence its course and reduce treatment time. The use of metalloproteinase inhibitors is an effective therapeutic strategy in the treatment of periodontal diseases. Conclusions. The therapeutic potential of metalloproteinase inhibitors may help prevent tissue damage in inflammatory periodontal diseases.

Subject. Xerostomia. Objectives. To analyze risk factors, to identify the incidence of xerostomia and a healthy lifestyle of students of the Faculty of Dentistry of the Ural State Medical University (USMU). Methodology. The work was carried out at the Department of Therapeutic Dentistry and Propaedeutics of Dental Diseases, at the Department of General Chemistry of USMU, at the Department of Controlled Systems Modeling of UrFU. The objects of the study were: a questionnaire consisting of two parts and volunteers – students of the Faculty of Dentistry of USMU. The first part of the questionnaire is based on the questionnaire "List of cases of xerostomia" modified by the authors of this study to 12 questions. The second part of the questionnaire (author's) consists of 29 questions on a healthy lifestyle (HLS), which also affect the development of xerostomia. Thus, the total number of questions in the questionnaire was 41. Statistical processing of the results was carried out on a personal computer using the Microsoft Excel 2007 application software package; the reliability of the differences was assessed by the Student's t-distribution using the Statistica 6.0 software package; the confidence interval for mathematical expectation M ± m was determined, where M is the sample average. The differences are considered. Conclusions. Students of the Faculty of Dentistry of USMU adhere to the rules aimed at maintaining the health of the oral cavity: they change their toothbrush (from 3 to 5 times a year – 85%), brush their teeth for at least three minutes (more than 48%) twice a day (77.7%) and use additional means of interdental hygiene (76.7%). 38% indicate dry lips.

Subject. Changes in the mineralization of hard tissues of teeth under the influence of radiation factor. Objectives. To study the effect of radiation factor on the level of mineralization of hard dental tissues by Raman fluorescence. Methodology. The study was conducted at the Department of Orthopedic Dentistry and Orthodontics of the SUSMU. The study was conducted on clinically removed teeth. All teeth were divided into three groups depending on the amount of radiation exposure (2 Gy, 70 Gy, 110 Gy). The main research method was the study of raman fluorescence of tooth sections on the hardware and software complex "InSpectr" with diagnostic sensitivity for the integral concentration of aerobic-anaerobic microbial suspension up to 109 CFU/ml. Teeth were examined in three areas (neck, equator, cutting edge) before and after radiation exposure. Results. Raman fluorescence diagnostics of the tooth surface made it possible to visually see the difference in mineralization in digitized indicators. For example, according to the indicators before and after exposure to the radiation factor, it is clear that the mineralization indicators, regardless of the dose, had no significant differences. At the same time, there are significant differences in the level of mineralization in the area of different tooth settings (equator, cervical region, cutting edge). Conclusion. In different areas of the tooth surface, the level of mineralization of hard tissues differs. The smallest is observed in the area of the neck of the teeth (incisors, y = 145 ± 1.5, x = 963 cm-1, canines, y = 141 ± 1.1, x = 963 cm-1, premolars, y = 142 ± 1.8 , x = 963 cm-1, molars, y = 143 ± 1.3, x = 963 cm-1), middle, in the area of the cutting edge and occlusal surface (incisors, y = 374 ± 1.7, x = 963 cm-1, canines, y = 377 ± 1.3, x = 963 cm-1, premolars, y = 375 ± 1.2, x = 963 cm-1, molars, y = 375 ± 1.1, x = 963 cm-1), and maximum, in the equator region (incisors, y = 413 ± 1.1, x = 963 cm-1, canines, y = 414 ± 1.9, x = 963 cm-1, premolars, y = 415 ± 1.7, x = 963 cm-1, molars, y = 419 ± 1.6, x = 963 cm-1). The method of Raman-fluorescence diagnostics makes it possible to detect changes in mineralization due to the potential difference in the areas of hard tooth tissues in various areas (neck, equator, cutting edge) of all functional groups of teeth (incisors, canines, premolars, molars) both before and after direct radiation exposure, direct radiation exposure does not significantly change the level of mineralization of hard dental tissues, regardless of the dose applied in all functional groups (incisors, canines, premolars, molars), in all areas of the teeth (equator, cutting edge, cervical region).

Subject. Today, the use of splint therapy is an essential part of specialized dental treatment, since in recent years the number of patients with dysfunctional conditions of the dentofacial apparatus, has increased significantly. In addition, according to recent research, the use of occlusal splints as part of complex therapy is effective in the treatment of neurological diseases, such as bruxism, chronic tension-type headache, and neuromuscular syndrome. Traditionally used designs of occlusal splints have some disadvantages, such as fragility of use, insufficient rigidity, and the impossibility of relining if the patient's dental status changes. The article provides a description and clinical and laboratory stages of manufacturing the developed new design of an occlusal splint reinforced with a titanium frame. Objectives. Increasing the effectiveness of treatment of patients with functional disorders of the dentofacial system through the development and implementation of a new prosthetic construction – a combined occlusal splint with a titanium frame, using modern intellectual and medical 3D technologies. Materials and methods. Titanium alloy (Rematitan®) was chosen as the material for the frame of the occlusal splint. Manufacturing method implies the use of additive technologies, in particular, 3D-printing for obtaining a high-precision structure with a minimum cross-sectional thickness. Hot-curing acrylic plastic was used to cover the parameterized frame; it is also possible to use a light-curing composite. Results. During the study, the expediency of introducing a reinforcing component in the form of a metal frame into the construction of the occlusal splint was determined. A new design of a combined occlusal splint and a method for its manufacture were developed. Conclusion. By reinforcing the occlusal splint with a titanium frame, high structural strength, durability of use, maintainability or relocation if necessary are ensured; at the same time, due to 3D-printing, the frame has a minimal cross-sectional thickness, which practically does not affect the thickness of the structure as a whole.

The literature provides information on the high prevalence of periodontal diseases and hard tooth tissues in patients in a psychiatric hospital. The relationship between periodontal microbiota and psychiatric pathology and the need to maintain oral health among this group of patients is discussed. The aim of the investigation was the study of the structure of periodontal diseases in patients of a psychiatric hospital, in various age groups. Material and methods of research. In the Republican Clinical Psychiatric Hospital named after V.N. Bekhterev (Kazan) in the period from 2014 to 2018, 200 patients (95 women and 105 men) aged 35 to 65 years (average age 56,26 ± 6,74) were examined. The questionnaire recorded the patient's age, sex, diagnosis of the underlying disease, dental formula, a standard periodontal diagram was filled in. The maximum depth of the periodontal pocket was determined by sequential measurements. The results of the study. In 100% of patients in a psychiatric hospital, periodontal tissue damage was detected, of which 86.5% in the form of chronic periodontitis. The maximum number of patients with periodontitis was detected in the age group of 51–60 years. The largest number of teeth removed in patients over 70 years of age. There was a direct strong correlation between age and the number of teeth removed (rp = 0.923; p < 0.001). The maximum depth of the periodontal pocket was also in the age group of 51–60 years and amounted to 4,25 ± 1,14 mm. A direct strong correlation of the depth of the periodontal pocket with the number of teeth removed was revealed. The deeper the patient has pathological pockets, the more teeth are removed (rp = 0.892). Conclusions. The results of the study suggest the need to develop training programs for patients and psychiatric hospital staff to improve the quality of life of patients and general health.
