The level of oral hygiene among many patients with implants is insufficient. In the absence of clinical examination and occupational hygiene, there is an averagely frequent development of inflammation in peri-implant tissuesperi-implantitis, which can cause implant disintegration. It is necessary to control hygiene indicators at the different stages of implantation. Objective: to analyze changes in hygiene and periodontal parameters during implant treatment. Materials and methods: At the stages before implantation, during osseointegration and the year after prosthetics on implants, the hygiene indicators and periodontal and microbiota status of 60 patients with dental implants were analyzed. Control methods used include Oral Hygiene Index Green J.C., Vermillion J.R. (OHI-S); gingivitis index Loe H., Silness J. (GI); Muhllemann index modified by Cowell; and PMA index modified by Parma. The level of halitosis was determined using the organoleptic index and the Halimeter instrument. Molecular genetic diagnosis of periodontopathogenic bacteria in the periodontal and peri-implant space was carried out. Results: Hygiene and periodontics after preimplantation tooth restoration, and periodontal deterioration by the time the implants open, then before replacing the temporary prostheses with permanent ones and after three months of functioning of the prostheses on the implants, which necessitates professional oral hygiene before these stages. Conclusion. Occupational hygiene every three months provides a stable adequate level of hygienic and periodontal indicators for users of prostheses on implants, and also reduces the detection of peri-implantitis.

The causes of mucositis or peri-implantitis may be insufficient oral hygiene, overload of implants. Recently, the attention of implantologists has been drawn to the design of the abutment connection node with the implant, which is able to accumulate the microflora of the oral cavity and maintain inflammation in the gum. The purpose of this work was to find out the opinion of dentists about the causes and methods of prevention of mucositis and peri-implantitis based on the results of many years of experience in prosthetics on implants. At the Department of Clinical Dentistry and Implantology of the Academy of Postgraduate Education of the FMBA of Russia, a survey was conducted of 48 orthopedic dentists who had at least 5 years of experience working with dental implants. The questionnaire contained 15 questions about the causes of peri-implant inflammation and its prevention methods. The above results of the questionnaire contain data on the frequency of use of 11 implant systems used in Russia; the detectability of inflammation in peri-implant tissues, bone resorption and gum recession when using various implant systems; the causes of inflammation in periimplant tissues; the role of the implant-abutment junction node. According to the results of the questionnaires, the importance of personal and professional hygiene in the care of installed implants was particularly noted, as well as the advantages of a deep cone connection of the abutment with the implant for the prevention of inflammation.

The purpose of the study: Comparison of indicators of dental status in athletes of the Olympic national teams and the population of Moscow of the same age.Material and methods: Dental examination of 132 athletes of the Olympic national teams and 104 residents of Moscow, males aged 2035 years was carried out using the modified World Health Organization Dental Status Assessment Card.Results of the study: Analysis of the prevalence and intensity of dental diseases showed that the dental status of athletes is worse in such areas as the detection of previously performed endodontic treatment and its unsatisfactory quality (with more endodontically treated teeth), the detection of large fillings and poor-quality fillings among existing fillings, prevalence pathological abrasion, the prevalence of periodontitis, the detection of unsatisfactory levels of oral hygiene, yyavlyaemost pathology of the temporomandibular joint. The obtained patterns reflect the untimely and insufficient quality of dental care for adolescents-athletes in the regions, as well as indicate higher psychophysical loads in athletes compared to peers. This necessitates special therapeutic and preventive approaches in the implementation of dental care aimed at reducing the parafunctional overload of the dentition in athletes.
