ZINC-PHOSPHATE CEMENT FOR FIXATION OF UNDETACHABLE CONSTRUCTIONS OF DENTAL PROSTHESES WITH ADDITION OF SILICON NANOPARTICLES

摘要

FIELD: medicine, pharmaceutics.;SUBSTANCE: invention relates to medicine, namely to orthopedic dentistry and can be used for fixation of undetachable constructions of dental prostheses. Composition for fixation of undetachable constructions of dental prostheses contains mixing liquid in percent by weight: phosphorus oxide -41%, zinc oxide - 10%, aluminium oxide - 4.5%, the remaining part - water to 100%, and mixture of powders, which contains in percent by weight: magnesium oxide - 10-11%, bismuth oxide - 3-3.5%, silicon oxide - 3-3.5%, aluminium oxide - 0.5%, chromium - 0.5%, silicon nanoparticles - 0.1-0.3%, zinc oxide - to 100%.;EFFECT: application of composition makes it possible to increase quality of fixation of undetachable constructions of dental prostheses due to increase of strength, increase of adhesive ability, resistance to oral fluid impact, reduction of film thickness and reduction of heat emission.;1 tbl
