. One of the most important social tasks is the protection and strengthening of people's health. In the modern world, there is a tendency towards an aging population that leads to an overall increase in disease and mortality. This situation is also directly associated with the deterioration of the oral health status of the population that leads to an increase in the number of patients with dentition defects. Especially marked morphological, functional and aesthetic changes in the maxillofacial region are due to anodontia. In dental practice, anodontia is usually corrected with complete removable dentures, and production of correct speech sounds is one of the main tasks when manufacturing and placing complete removable dentures. The purpose of this study was to investigate the peculiarities of the speech adaptation in patients wearing full removable dentures. Materials and methods. 2 groups of patients were created: the group A included patients having no dentition defects, and the group B, which involved patients with complete secondary adentia. The studies were carried out using the method of sound computer spectrography before prosthetic correction, immediately after the fixation of a complete removable denture, after in 3, 7, 30 days. Results and discussion. The method of sound computer spectrography enabled us to record the sound speech production in Ukrainian language by patients before prosthetic correction and during adaptation to the complete removable denture. The obtained graphs demonstrate qualitative differences between the sound production by the individuals having no dentition defects (control) and by the patients with complete secondary adentia. The graphs also demonstrate certain dynamic patterns of acoustic processes during the first 30 days of wearing the complete removable denture. Conclusion. Thus, the complete anodontia significantly reduces the force and clearness of most vowels. At the beginning of wearing the complete removable denture, usually in 3 days, the force of sounds [o], [u] and the sound frequency of [a], [o] are restored. Following the temporary deviation from the norm, the frequency and force of vowels are usually restored in 30 days.
