Zverkhanovsky O. IMPROVEMENT OF THE DESIGN OF COMPLETE REMOVABLE DENTURES IN THE COMPLEX OF PROSTHETIC STOMATITIS PREVENTION

The thesis is devoted to improving the quality of orthopedic treatment of patients with complete lack of teeth by improving the design of a complete removable prosthesis and developing a method for the prevention of prosthetic stomatitis. Clinical studies involved 114 patients with complete absence of teeth who had prosthetics re-dented and had a history of prosthetic stomatitis. As a result of bench studies and analysis of the stress and deformed state of various design schemes of plate structures, the variant of plates of acrylic plastics with a rhombic grid is offered, which has the best qualities in terms of strength characteristics and parameters of plasticity characteristics. Thus, the strength of plates with a square grid was 0.302 ± 18.6 ∙ 10—3 MPa, rhombic — 0.58 ± 1.76 ∙ 10—2 MPa. The technology of production of complete removable dentures with the simultaneous appointment of a preventive course of amaranth oil deposited in the prosthesis is developed, which allows to restore the capillary stability and thereby prevent or drastically reduce the activity of prosthetic stomatitis in persons prosthetized with complete removable lamellar prostheses. The proposed use of a modifed base with the use of amaranth oil signifcantly reduced the degree of inflammatory response from the mucous membrane of the prosthetic bed by 24.46 The application of the developed modifed surface of the base of the prosthesis with amaranth oil leads to a decrease of atrophy processes by 43.6 %. compared to the non-prevention group at all. The rhizome of the prosthesis base in the form of rhombic grooves for amaranth oil flling was improved by 18.8 % fxation compared to the fxation of conventional prosthesis due to the improvement of cohesion forces. The thesis presents a theoretical generalization of the experimental and clinical studies, a new vision of the solution of the problem of prevention of prosthetic stomatitis, orthopedic treatment of patients with complete defects of the dental rows by improving the technology of manufacturing bases of prostheses and the introduction of methods of prevention of prostatitis using amaranth oil. Key words: denture stomatitis, complete removable dentures, amaranth oil, plate dentures, orthopedic treatment.
