Currently, the use of non-precious metal alloys in fixed prosthetic restorations has warranted review of the work done sofar using precious metal alloys. One of the parameters exhibiting the success of castings done using non-precious metal alloys is porosity, which is evaluated through such methods as rod forms, waxing heat, to investing and other castability methods. The porosity ratios of cats similarly done employing different investment expansion methods have been evaluated. While there is no statistical difference due to different methods, the hygroscopic expansion method noted successful results.
目前，在固定义齿修复中使用非贵金属合金使得有必要对迄今为止使用贵金属合金所做的工作进行重新审视。体现使用非贵金属合金进行铸造成功与否的参数之一是气孔率，其通过棒状成型、蜡型加热、包埋及其他铸造性能评估方法来进行评估。采用不同包埋膨胀方法进行类似铸造的气孔率也已得到评估。虽然不同方法之间没有统计学差异，但吸湿膨胀法取得了成功的结果。
