Abstract
This clinical study assessed the corrosion behaviour of 4 types of nickel- chromium casting alloys commonly ušed in prosthodontic practice. The aim of study was to verify deposition of nickel and chromium into saliva after the dental product insertion into the mouth, to determine their exact concentrations by ET - AAS method.
Our project demonstrated that all analysed dental alloys - Remanium G soft, Wiron 99, Wirolloy and Heraenium NA could be ušed for dental dentures producing. Laboratory testing showed, comparing both nickel and chromium releases, Heraenium should be afraid of in the group of patients with the allergy inclination, compared to Remaium G soft and its lowest nickel and chromium concentrations can be considered as secure as possible.
