Three silver-base alloys containing varying amounts of tin and copper were prepared by induction melting and centrifugal casting, and their properties were evaluated and compared with those of the type III gold alloy, for their suitability for non-porcelain crown and bridge work in dentistry. Among these the alloy II (Ag−Sn−Cu−Zn) was found to possess the best combination of strength and ductility and highest corrosion resistance in artificial saliva. Also its wear resistance was found superior to alloys I and III and was comparable to that of natural tooth. Thus the alloy II was found to be quite a promising indigenous and economic silver-based cast alloy for crown and bridge prostheses.
