The castability of two low-gold and two silver-palladium alloys was evaluated, using a Type III gold alloy as reference. Six castings from each alloy were subjected to a castability test, in which the marginal sharpness of simulated crowns--that is, the edge diameter--was used to assess the castability. The mean crown edge diameters of the silver-palladium alloys were three to four times the corresponding diameters of the gold-based alloys. The differences between these two groups were statistically significant. It is concluded that the castability of the low-gold alloys studied was comparable to that of the Type III alloy, whereas the silver-palladium alloys studied had a castability that may result in technical and clinical problems.
以一种III型金合金作为参照，对两种低金合金和两种银钯合金的可铸性进行了评估。每种合金制作六个铸件并进行可铸性测试，其中用模拟牙冠的边缘清晰度（即边缘直径）来评估可铸性。银钯合金的平均牙冠边缘直径是金基合金相应直径的三到四倍。这两组之间的差异具有统计学意义。得出的结论是，所研究的低金合金的可铸性与III型合金相当，而所研究的银钯合金的可铸性可能会导致技术和临床问题。
