In a long-term in-vitro test the wear of enamel fossae, amalgam restorations and their opposing enamel cusps in the occlusal contact area was evaluated, qualitatively and quantitatively. The wear of enamel cusps differed from the wear of enamel fossae. The amalgam restorations wore down more rapidly than enamel fossae, but they were less destructive against their opposing enamel cusps. The wear of all tested materials was not linear. The results will serve as reference data for future long-term in-vitro tests of posterior restorative materials.
在一项长期体外试验中，对牙合接触区域的釉质窝、银汞合金修复体及其相对的牙釉质尖的磨损情况进行了定性和定量评估。牙釉质尖的磨损与釉质窝的磨损不同。银汞合金修复体的磨损比釉质窝更快，但它们对相对的牙釉质尖的破坏性较小。所有测试材料的磨损都不是线性的。这些结果将作为未来后牙修复材料长期体外试验的参考数据。
