Relevance: Before starting the treatment, the patient's medical history should be carefully studied. Special attention should be paid to the presence/absence of diseases of the cardiovascular system, kidney disease, endocrine pathology, and the psychological state of the body. These diseases can directly affect the dental status and worsen the clinical picture. Psychoemotional stress and inflammatory post-prosthetic complications are reciprocal risk factors. Psychophysiological disorders can lead to the development of dental complications in the oral cavity and vice versa, mucositis can cause a stress reaction in a person. This assumption served as the purpose of this study. Materials and methods: During implant treatment, the analysis of the psychophysiological state in patients with inflammatory post-prosthetic complications was carried out according to 3 parameters (the results of the questionnaire, based on heart rate variability and using software), parallel to the assessment of the dental status in 30 patients. Stress and mucositis should be treated simultaneously, with sedation support where necessary. Outcomes: All patients showed a high level of stress. During the dental examinationthe presence of inflammation of the parotid tissue was detectes. Conclusion: Psychoemotional stress can be one of the initiating factors in the development of inflammatory complications during dental implantation. The main task of a dentist is, first of all, to identify the early stages of the development of the disease, and secondly, to provide not only symptomatic, but also pathogenetic treatment, taking into account the factors that facilitate the development of this pathology.
