Purpose of the study. To assess the prevalence of early dental implants failure due to the violation of their osseointegration by means of stratification provided for targeted indicators within the structure of studied samples of different sizes. Research methods. In order to form a sufficient research sample of dental implants, data was collected from 10 dentists who specialized in dental implantation procedures, regarding the total number of placed dental implants, the total number of dental patients, who undergone dental implantation, and number of clinically registered cases of intraosseous fixtures loss during the early observation period (within 1 year after placement). Additional analysis was conducted for those cases of early dental implants failures, which were approved by the results of radiological examinations conducted at the time of clinical signs registration associated with impaired osseointegration of the implant according to the medical records data, in order to identify the characteristics of radiological changes within the bone tissue at the area of compromised intraosseous fixtures. Scientific novelty. The overall prevalence of dental implant loss during the early follow-up period was 4,60% (143 reported cases among 3106 placed implants), with the mean prevalence of early implant loss among the study samples of different sizes being 5,58±1,33%. Most often, cases of dental implants osseointegration disruption (45 cases out of 94 properly documented/47,87%) were identified by signs of intraosseous fixture mobility at the second stage of rehabilitation during the unscrewing of the cover screw and fixation of the healing abutment, which were not associated with pain or discharge from peri-implant area. Only on 8 two-dimensional images (12,5%) out of 64, it was not possible to verify clear signs of bone tissue changes in the peri-implant area, which could suggest a violation of the osseointegration of dental implants. Conclusions. Based on analysis provided among different sized samples of placed dental implants, it was noted that the increase in the absolute number of cases of early dental implants loss is associated with an increase in the number of placed implants in general, although the relative prevalence of this complication was practically similar in the structure of samples of different sizes. In 65,73% of clinical cases of dental implants loss during the early observation period, those were properly documented in the patients' dental charts, and in 61,54% of cases they were also confirmed by the radiological data.
