Tissue accumulation of nickel released due to electrochemical corrosion of non-precious dental casting alloys.
Specimens of four non-precious dental casting alloys intended for use in the ceramic-metal technique were implanted subcutaneously in the neck region of mice. The animals were killed after 5 months. Organs and tissues were tested as regards the concentration of nickel by means of atomic absorption spectrophotometry. The study showed that due to electrochemical corrosion nickel was released from implants and accumulated in some tissues and organs.
