This article highlights the problem of assessing the operational contamination of the surface of a post-resection removable maxillary obturator denture. Scientific works and developments devoted to cleaning removable dentures outside the oral cavity are rare and do not address the issues of maxillofacial prosthetics after jaw resection due to cancer. Acrylic plastics as a material for obturator dentures have the following disadvantages: a small amount of monomer may remain in the final product, and the surface of the denture contains micropores. This contributes to the accumulation of food debris, bacteria and their metabolites, which has an adverse effect on the chemical composition of saliva, metabolic processes in the prosthetic bed tissues, as well as on the hygiene of the oral cavity and the dentures themselves in patients of this category. The aim of the study is to improve the efficiency and reliability of an objective quantitative assessment of the contamination of the surface of these dentures during their use by patients using digital technologies. To achieve this goal, the authors developed a technique for quantitative assessment of operational contamination of the surface of a post-resection removable maxillary obturator denture, tested in the process of dynamic clinical dispensary follow-up for up to 36 months in 8 patients with maxillary post-resection defects formed as a result of combined treatment of midface tumors. The proposed technique allows to increase the objectivity and reliability of the quantitative assessment of the hygienic condition of removable orthopedic dental structures through the use of modern digital technologies that visualize and evaluate parameters automatically. This improves the ergonomics of conducting research and increases the quality of diagnostic measures, eliminating the subjectivity of the human factor thanks to automation.
