[Drawbacks of technological processes used for making permanent dentures].

The quality of dentures is most fully evaluated by corrosion resistance of their polished surfaces. The main drawback of steel dentures is due to the structure of stainless steel as a metallurgical alloy: it possesses carbide and titanium nitride microclots (liquations). Other shortcoming of technological processes of permanent denture making are such operations as chemical etching and soldering.

[The clinical manifestations of the electrochemical processes due to the finishing treatment of dentures made from stainless steel].

The authors propose to treat stainless steel dentures by grinding on organosilicon binding followed by 2 polishing procedures: with diamond paste and paste based on ultradispersed aluminum oxide powder. This technology improves the corrosion resistance of dentures and eliminates signs of diseases caused by electrochemical processes in the oral cavity more effectively than basic technology (vulcanite grinding and polishing with GOI paste).

[The finishing treatment of dentures made from corrosion-resistant steel].

Validates the new technology of processing dentures made of corrosion-resistant steel. The method is based on using modern abrasives (synthetic diamonds and spheric corundums), polymers, and organosilicon compounds for grinding and polishing instruments.

[Nonspecific resistance factors of the body in middle-aged and elderly patients with denture stomatitis].

Various manifestations of intestinal dysbacteriosis, from latent to diffuse ones involving the entire gastrointestinal tract, were detected in elderly and senile patients wearing removable dentures; in 36% of them nonspecific bacteremia was detected. These manifestations were most expressed in patients with allergic stomatitis. Patients wearing removable dentures and suffering from prosthesis-induced stomatitis should be followed up by gastroenterologist.

[Enhancing the performance properties of dentures made from corrosion-resistant steel by improving the polishing technology].

Presents electron microscopic data on the metal surfaces polished with paste TOI and diamond+ultradispersion (DUD) paste. Polishing with TOI paste leaves craters on metal surface, whereas after polishing with DUD paste the surface is smooth. A hypothesis on the mechanism of these phenomena is proposed.

[The physical modelling of the process of dental material wear].

The regularities of 12X18H9T corrosion-resistant steel wear were studied in relation to denture movement rate, pressure, and artificial environment characteristics. The factors responsible for steel wear were found to be contact pressure magnitude, the interacting crowns relative movement rate and acceleration, and salivary composition.
