Abstract in English
Nickel metal may cause systemic toxicity and allergy
The compatibility of dental casting alloys correlates with
their release of elements .The aim of this study was to
specify the relationship of the release of nickel from Ni-
Cr dental alloys with their composition , and to
determine the effects of thermal treatment of Ni-Cr
alloys during porcelain firing process on the release of
nickel .
Ranging Five Ni-Cr alloys commonly used in clinical
practice were used, They have different nickel
percentage Ranging between ٥٩،٣ and ٨١ % , two of
them containing beryllium .
