Surfaces of amalgam-fillings (Germadent) applied to extracted human teeth were treated in four variants. The adaptation of the fillings to the cavosurface margins was measured with SEM before and after thermal stress. Burnishing lead to a clear reduction of leakages, in contrast to carving. Fillings polished after carving, and especially after burnishing, have smallest marginal leakage. Thermal charges cause a small deterioration of marginal adaptation.
应用于拔除的人牙上的汞合金填充物（Germadent）表面采用四种变体进行处理。在热应力前后，通过扫描电子显微镜测量填充物与洞缘的贴合情况。与雕刻相比，打磨可明显减少渗漏。雕刻后尤其是打磨后进行抛光的填充物边缘渗漏最小。热负荷会使边缘贴合度略有下降。
