[Damage from galvanic corrosion of dental alloys]. 1979

H Zitter, and P Pitner

Failure analysis reveals, that using different materials for expansion screws and fixing elements may cause severe galvanic corrosion or pitting corrosion. Such failures can easily be avoided by using only one alloy with good passivation characteristics instead of different alloys.
