In vitro corrosion resistance of high-palladium dental casting alloys

Corrosion Behavior of As‐Received and Previously Cast Type III Gold Alloy

“…A 37°C standard temperature was chosen to represent the normal temperature of the oral cavity. Moreover, Fusayama solution has been considered the medium in which the electrochemical behavior of dental alloys most closely resembles that in natural saliva 19,28 . A cyclic polarization test that provides general information on the state of the electrode at various potentials was used.…”

“…Corrosion of dental alloys in the oral environment not only results in the deterioration of the restoration, but also involves a release of ions directly related to their biocompatibility 13,14 . Corrosion behavior of alloys depends upon their compositions, their electrode potentials, the stress over the metals, and surface roughness, in addition to the specific characteristics of different oral environments 15–22 …”

Influence of shape and finishing on the corrosion of palladium-based dental alloys

“…Nevertheless, the studies on the electrochemical properties of these alloys after casting reported satisfactory corrosion behavior. 11 , 15 Also, when testing high-palladium alloys, a spontaneous passive behavior in electrochemical conditions similar to those in the oral environment was shown 16 and a Ag-based Pd alloy could be recast up to 4 times with little effect on its corrosion susceptibility in artificial saliva. 17 …”

The Nallan–Nickel Effect: A Mechanistic Perspective on Burning Sensations and Lichenoid Reactions in Long-Serving Porcelain-Fused-to-Metal Restorations

“…Minor elements (iron, manganese, silicon, carbon) fine-tune mechanical performance [ 11 ]. Noble and high-noble alloys incorporate greater proportions of precious metals that enhance passivity and biocompatibility (e.g., palladium for hardness/corrosion resistance; gold for corrosion resistance/ductility) [ 12 , 13 , 14 , 15 ].…”
