Mould Filling of Ag-Pd-Cu-Au and Ag-Zn-Sn-In Alloy Castings made using a Rapidly Prepared Gypsum-bonded Investment Material

Abstract - Mandibular premolar-shaped wax patterns of full crowns with a marginal angle of 30° were prepared. Two semiprecious alloys were cast using a rapidly prepared gypsum-bonded investment material or a conventional gypsum-bonded investment. A precise impression was taken and cut into four segments. Scanning electron microscopy was used to evaluate the mould filling of each segment. The mould filling of the silver-palladium-copper-gold alloy was worse than that of the silver-zinc-tin-indium alloy. The mould filling of both alloys cast with the rapidly prepared gypsum-bonded investment material was superior to that using the conventional investment.
