Observations of 'Economical' Fixed Prosthodontic Alloys,

Abstract

Composition, microstructure, heat treatment characteristics and mechanical properties of four alternatives to conventional high noble fixed prosthodontic alloys were studied. The materials exhibited a broad range of compositional and mechanical property differences. As cast tensile properties of three of the materials paralleled those of type III casting golds. Precipitation and order-disorder transformation appear to be the principal mechanisms of hardening. These alloys exhibit properties suggesting their potential usefulness in fixed prosthodontics; however, the silver-palladium and silver-indium materials require meticulous attention to melting and casting technique to minimize the incidence of overheating and casting porosity.
