The results of the adhesion of microorganisms to the surface of the modified prosthetic obturator

t Obturator prostheses can be populated by microorganisms and function as a reservoir of infection. After resection of the upper jaw, the obturators are also exposed to microorganisms living in the nose and paranasal sinuses. The aim is to evaluate in vitro biofilm formation by various types of oral bacteria on titanium and polyesteresterketone (PEEK) samples from experimental groups.
