The article gives a detailed analysis of oral cavity microbiocenosis features of 36 patients with type II diabetes for 5 years. These data reflects microbiocenosis features before and after orthopedic treatment with metal-ceramic and pressed crowns. These results indicate that frequency of occurrence and the number of microorganisms of the genus Streptococcus, Staphylococcus (including S. aureus), Peptostreptococcus and Candida is significantly higher in patients after orthopedic treatment with pressed crowns than with metal-ceramic crowns. A high percentage of normal microflora, particularly lactobacilli (60%), was revealed on gingival mucosa in patients after orthopedic treatment with metal-ceramic crowns.

The lack of personalized dispensary registration after prosthetics of dentition is the cause of many complications and a decrease in the quality of life of patients. Purpose: To develop and justify the timing of dispensary follow-up among patients with partial and complete loss of teeth, prosthetics with removable and bridge dentures. Material and methods. A three-year prospective study was conducted of 364 patients with missing teeth who received appropriate treatment. According to the existing scheme, the control group included 199 patients who underwent dispensary follow-up after prosthetics. The study group included 165 patients observed according to the newly proposed terms. Face-to-face and telephone interviews using the SF-36 quality of life questionnaire were used as research methods, complications of the treatment were taken into account and analyzed. Results: Based on the conducted studies, such factors as the presence of vital teeth as prosthesis supports, the presence of periodontitis in the anamnesis, the presence of supporting teeth restored with fillings, many somatic diseases in the anamnesis, the factor of repeated/primary prosthetics were statistically significant for the correction of the terms of dispensary observation. Each of the factors is assigned a certain number of points. Considering the above reasons, we have identified three dispensary groups for patients after dental, orthopaedic treatment of partial and complete loss of teeth. When comparing the study group and the control group, it was found that in the near and distant periods, there was an increase in the quality of life of patients on the scales of “mental health”, “role functioning due to physical condition”, “social functioning” and “vital activity” in the study group. Conclusion: The introduction into practice of orthopaedic dentists of the proposed terms of dispensary observation of patients after prosthetics of dentition will improve patients’ quality of life according to the indicator “mental health” and reduce the risk of conflict situations.

The adhesion of oral microorganisms to the surface of teeth and dental restorative materials is often the starting point in the developments of caries and periodontal disease. Formation of biofilm on the surface provisional acrylic bridge is especially quickly and can potentially generate decay or periodontal disease on the teeth. Occlusion trauma and occlusion disorders effects on increasing of injure regional periodontal tissues. Using ultrasonic doppler diagnostics oral mucosal blood flow was measured in 79 patients with periodontitis of medium severity with different hygiene conditions before and during orthopedic treatment by provisional fixed dentures was model by different methods. According to the results of this study was stated optimization of oral mucosal blood flow after pre-prosthetic treatments and the supportive hygiene periodontal care during the treatment. Results was used for reduce of functional stress in the in periodontal tissues during the orthopedic alignment by the use of fixed dentures. Specific prosthodontic hygiene protocol and model by individual articulator must be used to treat patients with widespread chronic periodontitis by interim prostheses.
