The aim of the study. Determination of the degree and quality of osseointegration of implants placed on the upper jaw in middle-aged patients, residents of the Transcarpathia. Materials and methods. 250 middle-aged people, residents of the Zakarpattia region, with defects of the upper dentition were studied. Evaluation of osseointegration of 450 implants installed on the upper jaw was carried out using the Periotest M device and computer tomography. The qualitative characteristics of the bone tissue around the implants were evaluated according to the recommendations of Linkevicius T (2020); Quantitative analysis of radiological examination results was assessed by measuring bone tissue level limits, quantifying the qualitative reactions of bone tissue. Mathematical analysis and verification of the reliability of the results, as well as calculation of arithmetic mean and mean square errors were carried out on the basis of the software «Statistica 6.0». Results and their discussion. After 36 months, mobility indicators corresponded to grade 0 in 85.9% of cases, grade I mobility in 9.4% of cases, grade II in 4.7% of cases. In the complex analysis of the quality of the bone tissue around the implants of all groups, positive bone tissue reactions were established, a stable bone level prevailed in all groups at all observation periods (p>0.05), the frequency of cases of progressive resorption did not exceed 15%. No significant difference between the incidence of progressive resorption (p>0.05) and demineralization (p>0.05) was reached after 12 and 36 months around the implants in patients of all groups. Conclusions. According to the obtained results of cone-beam computed tomography 6, 12 and 36 months after the fixation of the orthopedic structure with support on intraosseous dental implants on the upper jaw, a significant influence of structural features on the qualitative and quantitative state of the bone tissue around the implants was established.
