Two independent research groups evaluated marginal failure and conducted creep tests on 10 commercial amalgam alloys. Correlation data determined that both laboratory tests and clinical results were essentially the same between the two studies. The 2-year clinical results indicate that five alloys, Cupralloy, Dispersalloy, Indiloy, Phasealloy, and Tytin give best results. Creep correlated with the rate of marginal failure within a study when all alloys were assessed; however, for the seven gamma-2-free alloys, there was no significant relationship between in vivo and in vitro data. Since creep tests did not predict marginal failure of the gamma-2-free alloys, the results of clinical studies should be the guide to selection of the better amalgam alloys.
两个独立的研究小组评估了边缘性破坏情况，并对10种市售汞合金进行了蠕变试验。相关性数据表明，两项研究中的实验室测试和临床结果基本相同。两年的临床结果表明，Cupralloy、Dispersalloy、Indiloy、Phasealloy和Tytin这五种合金的效果最佳。在评估所有合金时，一项研究中蠕变与边缘性破坏率相关；然而，对于七种不含γ-2的合金，体内和体外数据之间没有显著关系。由于蠕变试验无法预测不含γ-2合金的边缘性破坏，临床研究结果应作为选择更好汞合金的指导。
