Dr. Kaán, B., Dr. Eichner, K., Dr. Fejérdy, P., Dr. Kaán, M., Róth, L.: In vivo and in vitro investigation of marginal fot of ceramic fused to gold inlays

In the view of the patiens, 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 pm 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.
