On the issue of hygienic maintenance of post-resection maxillary obturator prostheses (literature review)

Abstract

Based on literature data, this article reviews a range of problems associated with hygienic care after obturation prostheses and the oral cavity after combined treatment of malignant neoplasms. At the present time, replacing prosthetic care after maxillary resection due to malignant neoplasms using obturator prostheses is the main method for rehabilitation of oncological patients. Such methods as dental prosthetic care based on dental implants and removable dentures for elimination of partial and complete edentulism is impossible in such conditions. A defect in the maxilla, an oronasal fistula, post-operative and post-radiation jaw contracture as well as hyposalivation, impair the hygiene of the oral cavity. Acrylic plastics used for production of obturator prostheses have such substantial flaws leading to development of inflammation and progression of atrophy in the supporting tissues of the basal seat. This reduces short-term and long-term efficacy of orthopaedic dental rehabilitation procedures after replacing dental prosthetics. A conclusion has been drawn on the necessity of development and practical introduction of a special complex of dental hygienic procedures — professional and individual — adapted for oncological patients that would be implemented within the framework of dynamic dispensary observation in the setting of a dental polyclinic.
