The choice of materials depending on the topography of partial dentition defects

A component of the integrity of the dentofacial system, ensuring its normal functioning, is the intactness of the dentition. Defects in the dentition arise due to untimely treatment of diseases of the hard tissues of the teeth and periodontal or other reasons. The absence of individual teeth and the formation of defects in connection with this not only lead to a violation of the function of chewing and speech, but also pose a threat to the existence of other parts of the chewing apparatus. To ensure normal functional activity of the dentition, defects in the dentition are restored by dentures. To study the depth of immersion of the prosthesis in the mucous membrane of the prosthetic bed, an ultrasonic research method was used. Upon receipt of the impression, differences were found in the immersion depth of the base of the removable prosthesis, depending on the compression of the mucous membrane of the prosthetic bed. The success of treatment and prevention with the use of removable and non-removable designs of dentures depends on the correct preparation of an orthopedic treatment plan, on the selection of an adequate design of dentures and especially on the hygienic condition of dentures that the patient has been using for a long time. Atrophic changes in the tissues of the prosthetic bed often lead to failure of the orthopedic design and can further complicate the repeated prosthetics of patients (V.A. Zagorsky, I.S. Redinov, 1993). Conducting regular follow-up examinations of patients using removable dentures helps to timely detect changes in underlying tissues and prevent or slow down unwanted processes (A.N. Ryakhovsky, 1992). Thus, hygienic care for various types of dentures is of particular importance for the normal structural and functional activity of the organs of the oral cavity. With thorough and proper hygiene of the oral cavity and dentures, the normal functioning of the various links of the three level barrier of the oral cavity is maintained, and the terms of use of dentures are increased.
