Reasons for refusal of repeated prosthetics on implants according to the results of a patient survey

Abstract

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.
