Purpose: to analyze the frequency and causes of failures of patients with removed implants from repeated prosthetics on dental implants. Material and methods: The consent or refusal of repeated prosthetics on implants was analyzed in 256 patients with indications for implantation and with previously removed implants. Among the prostheses were both removable and non-removable. 46 patients needed covering prostheses on implants, 14 – non-removable dentures with complete absence of teeth, 58 – non-removable dentures with partial absence of teeth. If the patient refused to perform implantation, he filled out a specially designed questionnaire of 16 questions. Results: The failure rate of patients with removed implants from re-implantation and prosthetics on implants reaches 46.1%. The main reasons for the refusal of patients from re-implantation are: insufficient period of functioning of prostheses on implants (62.7%) due to the development of chronic inflammation around the implants (55.9%); high cost of prosthetics on implants (44.1%); insufficient good health, constraining the decision on surgical interventions and complex prosthetics (43.2%). Significant factors for refusing implantation can be considered the duration of the prosthetics process on implants, the reluctance of additional bone-plastic surgery, insufficient aesthetics of fixed prostheses on implants. In the complete absence of teeth, the impossibility of permanent prosthetics due to the lack of conditions for installing the proper number of implants causes more than half of the refusals from implantation. The results obtained on the frequency and reasons for rejections of re-implantation among people with previous experience of using prostheses on implants, in fact, reflect a subjective assessment of the effectiveness of prosthetics on implants. According to the survey data, the directions of the necessary improvement of the implantation method and the organization of dental implantology were revealed. In particular, measures are required to effectively prevent chronic periimplant inflammation as a reason for reducing the service life of prostheses on implants; it is necessary to reduce the cost of prosthetics on implants and the implants themselves; to improve the methods of non-removable prosthetics in the complete absence of teeth.
The main purpose of this study was to analyze the reasons for refusal of repeated prosthetics on implants of patients with removed implants. The analysis of the causes of such failures was carried out in 118 patients with removed implants with a period of 5—20 years of previous use of prostheses on implants. For 46 patients with repeated prosthetics were shown covered dentures on implants, 14 — fixed dentures with complete absence of teeth, 58 — fixed dentures with partial absence of teeth. To analyze the reasons for refusal of prosthetics on implants, a questionnaire of 16 questions was developed and used. As a result of the study, it was found that the main rea sons for the refusal of patients from re-implantation are the insufficient period of functioning of prostheses on implants due to the development of chronic inflammation around the implants, the high cost of prosthetics on implants and insufficient good health, constraining the decision on surgical interventions and complex prosthetics are a problem. Significant factors for refusing implantation were also noted: the duration of the prosthetics process on implants, the reluctance of additional bone-plastic surgery, insufficient esthetics of fixed prostheses on implants. More than half of the refusals from implantation in the complete absence of teeth are due to the impossibility of non-removable prosthetics.
