[Clinical significance of zinc phosphate cement microstructure for permanent denture fixation].

Electron microscopic study of the structure of zinc-phosphate cement fixing artificial crowns detected its porous structure: isolated cavities and connected 0.3-10 mcm microspaces. These formations in the cement structure are stable and do not depend on the duration of permanent fixation of dentures.

[Changes in the mixed salivary indices during orthodontic treatment].

The function of the blood-salivary barrier at different stages of orthodontic treatment of secondary partial adentia depends on the psychoemotional status of a patient. Such a conclusion was made after investigation of mixed human salivary pools. Total sialometry was carried out for objective evaluation of the level of salivary secretion.

[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).
