In the view of the patients, Galvano-Inlays fulfil esthetic requirements in contrast to cast restaurations. However, it was decided to evaluate the fine gold margins. The marginal seal of Galvano-Inlays in different stages of production was evaluated by means of light microscopy, and scanning electron microscopy. In addition Galvano-Inlays which had been in the mouth for two years, were evaluated in the same way. Besides good contact of the fine gold to the tooth, marginal discrepancies in the range of 60 to 160 microns were found which can hardly be improved by means of burnishing. After all, the insufficiency results from the inevitable gap of cementation or from breaking failure of the polished and thus hardened margin of the fine gold.
在患者看来，与铸造修复体相比，电铸嵌体符合美学要求。然而，决定对纯金边缘进行评估。通过光学显微镜和扫描电子显微镜对不同生产阶段的电铸嵌体的边缘封闭性进行了评估。此外，对已在口腔中使用两年的电铸嵌体也进行了同样的评估。除了纯金与牙齿的良好贴合外，还发现边缘差异在60至160微米范围内，通过打磨几乎无法改善。毕竟，这种不足是由不可避免的粘固间隙或纯金抛光硬化边缘的断裂失效造成的。
