Modification of an amalgam alloy may give rise to improved physical properties. The physical properties of a newly formulated, single-composition lathe-cut amalgam alloy were studied and found to be superior to those of a conventional lathe-cut amalgam alloy. However, such modification in formulation may result in changes in the clinical handling properties of the material. The high-copper amalgam alloy was assessed by a panel of general practitioners who found that the general handling properties of the material were similar to those of conventional lathe-cut amalgam alloys. The longer term performance of the high-copper alloy was assessed by means of a blind, controlled clinical trial carried out by two operators. A 1-year assessment of the resulting restorations and tooth replicas could not distinguish between the high-copper alloy and a conventional alloy. The two alloys had both given good clinical results.
汞合金的改性可能会带来物理性能的改善。对一种新配制的单成分车削汞合金的物理性能进行了研究，发现其优于传统车削汞合金。然而，这种配方上的改性可能会导致材料临床操作性能的变化。一组全科医生对高铜汞合金进行了评估，他们发现该材料的总体操作性能与传统车削汞合金相似。高铜合金的长期性能通过由两名操作人员进行的一项盲法对照临床试验进行评估。对所得修复体和牙齿复制品进行的为期1年的评估无法区分高铜合金和传统合金。这两种合金都取得了良好的临床效果。
