The influence of finishing and size of the restorations using five amalgam alloys (Aristaloy, Dispersalloy, Oraloy, Sybraloy, and Tytin) was evaluated at 30 mo. when size of the restoration was considered, Dispersalloy displayed the best margin performance. Oraloy, Sybraloy, and Tytin were inferior to Dispersalloy and were grouped together. Aristaloy was inferior to all other alloys in the study. When the aspect of finishing was considered, Dispersalloy and Sybraloy evidenced excellent margin performance when unfinished. Aristaloy showed the worst margin performance of all the alloys in the study when unfinished, but showed remarkable improvement in margin performance when finished.
在30个月时评估了使用五种银汞合金（Aristaloy、Dispersalloy、Oraloy、Sybraloy和Tytin）进行修复体修整和尺寸的影响。当考虑修复体尺寸时，Dispersalloy显示出最佳的边缘性能。Oraloy、Sybraloy和Tytin不如Dispersalloy，并被归为一组。Aristaloy在该研究中比所有其他合金都差。当考虑修整方面时，Dispersalloy和Sybraloy在未修整时表现出优异的边缘性能。Aristaloy在未修整时是该研究中所有合金中边缘性能最差的，但在修整后边缘性能有显著改善。
