Abstract

Were conducted comparative tests of corrosion properties in artificial saliva precious metal alloys based on gold for metal-ceramic dentures Plagodent-plus, Plagodent (both of JSC «“SUPERMETALL” name E.I. Rytvin») and VitIriy (LLC «Medical company “Vital EBB”»). Tests included voltammetry and XRF analysis, showed that the alloy Plagodent-plus has a higher level of corrosion resistance compared with alloys Plagodent and VitIriy.
