PROSTHETICS OF PATIENTS WITH UNFAVORABLE CLINICAL CONDITIONS FOR FIXATION AND STABILIZATION OF REMOVABLE DENTURES

The article is devoted to the study of prosthetics in patients with unfavorable clinical conditions for the fixation and stabilization of removable dentures. The authors substantiate the relevance and significance of the research topic. The relevance of the study is justified by the introduction of digital dental technologies for modeling and manufacturing dentures into dental practice. The most accessible digital method for the manufacture of removable dentures is 3D printing, however, questions remain about the physical-mechanical, toxicological and microbiological properties of structural materials, photopolymer resins used in the additive manufacturing of dental structures. There is a complete lack of data in the scientific literature on the adhesive strength of removable dentures made by volumetric printing to dental adhesives for their fixation in the oral cavity. The traditional methods of fixing removable plate prostheses in patients with complete absence of teeth are considered; the factors complicating the processes of dental (orthopedic) prosthetics treatment are clarified. The materials for the study were fundamental (dissertations, laboratory research reports) and non-fundamental (scientific articles) works by Russian and foreign authors devoted to the problem of prosthetics of patients with unfavorable clinical conditions for fixing and stabilizing removable dentures. A set of research methods was used, combining general scientific (analysis and synthesis of literary data, comparative analogy, extraction of information from scientific sources) and special methods (systematic and comparative analysis). A review of the literature and an analysis of the experience gained in international clinical practice in the field of the use of additional means of fixation and stabilization of removable plate prostheses – mechanical and chemical is presented. The conclusion is that it is necessary to further study adhesive creams for fixing removable dentures in patients with unfavorable clinical conditions, to develop and confirm the effectiveness of methods for determining their adhesive ability to modern structural materials used in additive manufacturing technologies.
