[The morphofunctional characteristics of the blood supply to the oral mucosa in the absence of teeth and their prosthesis].

Morphofunctional features of blood supply to the buccal mucosa were studied by rheography, polarography, light and electron transmission microscopy and stereo-morphometry in patients with partial adentia and after they were fitted with prostheses. Adentia changed the functional parameters, this being indicative of reduced circulation. Morphologically it manifested by microvessel stasis, red cell sludging, stromal edema and polymorphonuclear infiltration. Endothelial ultrastructure and ultrastructure of other microvessel components indicated impaired permeability. Fitting with prostheses resulted in recovery of the functional parameters and of the buccal mucosa morphology. All the parameters sooner normalized if bridge prostheses were implanted. Circulatory functional parameters and buccal mucosa microvessel structure were in good correlation.
