THE EFFECT OF COMPLETE REMOVABLE DENTURES ON BLOOD MICROCIRCULATION IN THE TISSUES OF THE PROSTHETIC BED

A comparative study of the effect of hard and two-layer (with soft lining) bases of complete removable dentures on the tissues of the prosthetic bed was carried out using the method of laser Doppler flowmetry in 40 patients with complete secondary adentia. It has been established that the use of complete removable dentures affects the intensity of blood circulation in the microcirculatory bed of the mucosa of the prosthetic bed. Changes that occur in the blood supply of tissues under prostheses with rigid bases are reversible and return to their original values after at least 6 months, or even blood supply increases adaptively, however, on the other hand, it significantly and irreversibly impairs the blood supply to the tissues of the prosthetic bed, which in the long term can cause a dystrophic decrease in the volume of the bone base, and under a prosthesis with a rigid base, the changes are reversible and after 6 months the blood filling adaptively increases.
