Diagnostic Value of Von Willebrand Factor on Changes in Tissue Oxygenation during Dental Implantation in Persons with Previous Coronavirus Disease

Abstract

On the background of the wide introduction of dental implants into the dental practice, according to the data of some authors, the rate of complications at the different stages of dental rehabilitation of patients with dental implants is increasing. At present the scientists of the world pay more attention to the problem of pandemic-Covid-19. The whole population living on the Earth was exposed to a mild to moderate coronavirus infection, 58% of the Earth's population suffered from this infection in a severe form and 27% were fatal. From the implantologist's point of view, it is important that with prolonged arterial hypertension, reduced immunity with Covid-19 and regular administration of hypotensive, anticoagulant drugs, the phenomenon of "rarefaction" or "rarefaction" occurs, which is expressed in a reduction of the total surface of the exchange vessels [Jablonski D, 2014]. The von Willebrand factor (vWF) can serve as a prognostic and diagnostic marker of insufficient oxygen delivery to the tissues during recuperation and an indicator of the need to correct the ongoing therapy aimed at normalization of hemostasis disorders.
