A new method to prevent the corrosion of dental metals, during disinfection using functional water: Sacrificial protection

Abstract

Purpose: This paper demonstrates a simple method using sacrificial protection for preventing the corrosion of dental metals.
Methods: Dental metals are directly connected or/and wound with a pure commercial aluminum/zinc wire/plate with high ionization tendency, before their immersion into oxidizing functional water.
Conclusion: Dental materials such as Co–Cr alloy wires, stainless steel, and Au–Ag–Pd alloys did not corrode when this method was used. Thus, this method is very simple and effective for preventing corrosion of dental metals during disinfection using functional water.
