Introduction. The prevalence of total edentulism differs significantly between countries, cities and regions within the same country. It can be affected by various factors, such as age, sex, and socioeconomic factors along with lifestyle and health behavior. Data from the World Health Organization (WHO) and independent studies in 42 countries show that the prevalence of total edentulism is the lowest in Nigeria (1.3%) and the highest in Bosnia-Herzegovina (78%) among those aged >65 years. Nowadays, in the European Union, more than 50% of the population aged> 70 years suffer from total or partial edentulism. Material and methods. As part of this study, 7 patients aged between 50-78 diagnosticated with maxillary total edentulism, from the University Dental Clinic. During the treatment were used two technique of final impression, first by Herbst, second purpose by school of Bucharest. Results. All patients were informed about the study and signed an informed consent. The study was carried out over a one-year period, evaluating the success of prosthetic treatment of maxillary total edentulism using total dentures. The patients, who had the prosthetic field impressed according to Herbst's method, needed 3 corrections, which were carried out in the following days after the prostheses were delivered. And the patients who had the prosthesis impressed according to the Bucharest School's concept needed to have the edges of the prosthesis retouched 4 times. Conclusions. A comparative analysis of functional impression methods has shown that the difference between prostheses obtained by these methods is minimal and depends largely on the capabilities of the treating doctor.
