“…As mentioned above in 12.4.1.2, Ag-Pd-Cu-Au alloys are most important dental metallic materials in Japan, and it is well known that these alloys exhibit age hardening behavior [12][13][14][15]. However, it has been reported that the mechanical strength of an Ag-20Pd-12Au-14.5Cu (mass%) alloy is significantly enhanced when the alloys are subjected to solution treatments at temperatures higher than 1,073 K and subsequent water quenching without being subjected to aging treatment [16].…”

In dental treatment, treatment for restoring teeth (crown restorations) and for compensating for missing teeth (prosthetic treatments for missing teeth) involves the appropriate selection of metallic, ceramic, polymer materials or a combination of these materials as necessary for each individual patient. These devices are often tailor-made by dental technicians. Metallic materials also play an important role in dental implants and orthodontic treatments. In this chapter, various types of treatment in clinical dentistry under the intraoral environment are introduced, and then an outline of the types and characteristics of metallic materials used in the dental devices required by the aforementioned treatments is provided. Further, a recent progress of research about Ag-Pd-Cu-Au alloys that are the most important dental metallic materials in Japan is reviewed.

“…Recent trends have shown that low-noble dental alloys (Ag and Pd alloys, known as white alloys) are attracting much attention as alternatives to Au alloys because of their lower price [6][7][8]. Thus, Ag-based alloys such as Ag-Pd-Cu-Au [9][10][11][12][13][14][15][16][17][18][19], and Ag-Cu-Pd-Au [20,21] alloys have reached commercial status. Alloys like Unique White 66Ag 22Pd 10Cu 1In (wt%) and Paliag 50Ag 30Pd 15 9Cu 3Au 1Zn have achieved large recognition on the dental alloy market [22].…”

Higher-noble dental alloys (Au, Ag, and Pd) are the most desirable for dentistry applications, but they are expensive. Low-noble (Ag, Pd, Cu) dental alloys are alternatives to higher-noble ones due to their lower price. In this regard, the paper supports the price lowering of dental alloy by increasing the Cu content, i.e., a new 58Ag24Pd11Cu2Au2Zn1.5In1.5Sn dental alloy. The increasing addition of the Cu leads to a complex structure consisting of a solid solution that engulfs compounds of micrometric and nanometric sizes. The 58Ag24Pd11Cu2Au2Zn1.5In1.5Sn has demonstrated a much better electrochemical corrosion behavior in artificial saliva compared to the Paliag and Unique White dental alloys. The improved corrosion behavior of the new alloy is supported by the diminishing of the Cu selective diffusion into the electrolyte due to its retaining into compounds and into Ag-Pd solid solution. Also, the synergic effects of Cu, Zn, In, Sn may improve the corrosion resistance, but they have strengthened the 58Ag24Pd11Cu2Au2Zn1.5In1.5Sn matrix. The main finding addressed in the paper consists in a new 58Ag24Pd11Cu2Au2Zn1.5In1.5Sn dental alloy with improved corrosion resistance in artificial saliva.
