Abstract. This article presents the results of a clinical study of the stability and process of osteointegration implants of 11 known implant dental systems. The effect of the microstructure of 3 types of implant surface (HSTTM, SLA and RBM) and their design features (shape, size, type of carving) on the indicators of their stability and osteointegration process during immediate and delayed implantation with immediate functional load is shown and analyzed. The stability of the implants and the
... ynamics of the quality of osteointegration were determined by the devices «Osstell Mentor» and «Periotest» in the process of treatment, starting from the moment of implant installation in different eras (2 weeks, 1 month, 2 months and 3 months). 414 patients between the ages of 20 and 70 were monitored. Of these, there are 249 and 165 male women. The average age of the operated patients was: for men – 54 years for women – 49 years. All patients were divided into two groups of the first – 109 patients who after extraction were directly implanted into the hole of the remote tooth with the subsequent immediate load, the second group – 305 patients who were delayed implantation with immediate load. A total of 1,302 implants were installed. The study revealed a link between the type of surface of the implant, primary stability and the time of its osteointegration during certain periods of clinical observation. The results of the study demonstrated the important role of combining microstructure of the surface, design and dimension features, the type of insertion of implants on their primary stability and the process of osteointegration in the conduct of both immediate and delayed implantation. Key words: frequency resonance analysis, damping, stability, osteointegration, fixation, implants, periotestometry, immediate implantation.
