COMPARATIVE ASSESSMENT OF THE STATUS OF PERI-IMPLANT AND PARODONTAL TISSUES

One of the controversial issues of modern dentistry is the assessment of how parodontitis arises or aggravates in the area of own teeth the severity of its course after installing orthopedic structures with support on dental implants affects the state of peri-implant tissues. Using clinical, R-genological, molecular genetic methods of research, to give a comparative assessment of the condition of parodontal tissues of own teeth and peri-implant tissues in patients who have been using fixed orthopedic constructions with support on dental implants for the treatment of partial secondary adentia for more than 5 years. To achieve this goal, we formed two groups of patients. Group 1 consisted of 34 patients (19 female and 15 male) who did not have secondary biological complications of dental implantation. The average age of patients in this group was (m. 61.3±7.8 years, f. 58.4±8.1 years) the average service life of orthopedic structures with support on dental implants was 8.3±2.3 years. The 2nd group consisted of 27 patients (15 f., 12 m.) who, on the basis of a clinical examination, R-gene examination, were diagnosed with: peri-implantitis in the area of one or more implants serving as a support for a fixed orthopedic structure. The average age of patients in this group was (m. 63±8.2 years, F 59.6±7.7 years). The average service life of an orthopedic construction was 8.8±2.5 years. In a comparative analysis of the species composition of microorganisms in the tissues of pathological parodontal pockets and peri-implant sulcus, the quantitative and species composition of microorganisms is identical in 75% of the examined patients and is individual for each patient. Based on a clinical examination, analysis of panoramic R-graphs data, parodontal diagnosis was made to patients of the 1st and 2nd groups. Based on a comparative assessment of the status of parodontal peri-implant tissues, their microbial contamination, in patients who successfully used fixed orthopedic constructions supported by dental implants to replace partial dentition defects for more than 5 years, it was found that the resistance of microbial invasion of peri-implant tissues is higher than the parodontal tissues of own teeth.
