The corrosion resistance of a new cobalt-chromium-molybdenum-ceramic alloy.

Cobalt-chromium alloys are extensively used for removable partial dentures and implants. Recently, this type of alloy has been introduced for porcelain-fused-to-metal crown and bridgework. The objective of this in vitro study was to evaluate the corrosion behaviour of such a ceramic alloy (Vicomp) and compare it to a cobalt-chromium alloy for removable partial dentures (Vitallium). A 0.9% saline solution and an artificial saliva were used as electrolytes. Results indicate a similar, adequate, corrosion resistance.
