Introduction. The increase in life expectancy means that the number of patients requiring prosthetic rehabilitation using removable dentures is still increasing. Prosthetic treatment aims to rebuild lost teeth and restore these functions, eliminate parafunctions, prevent prosthetic conditions and disorders of the stomatognathic system (US). Reports from the literature say that correctly made removable dentures have a positive effect on improving the quality of life among the examined patients and it does not depend on the technique of making dentures. Aim. The aim of the study was to analyze the quality of clinical and laboratory performance of removable dentures and to assess their impact on the acceptance of dentures and the quality of life of patients. Material and Methods. 56 people participated in the study. Each patient underwent a test to assess the type of deficiencies, to assess the type of prosthetic base (for toothless patients), the time of use of existing prostheses, scope, retention and stabilization, as well as the resting and short-circuit height of old and new prostheses. A QoL assessment survey was also used. The results were statistically analyzed. Results. The analyzes show that patients do not attach importance to the parameters determined at the stages of occlusion registration. Retention and stabilization of restorations have the greatest impact on the positive reception of dentures. Conclusions. The proper retention of the jaw prosthesis has an impact on the satisfaction of using removable dentures.

Key words: satisfaction with dentures, laboratory workmanship, retention, stabilization.
