Galvanoceramic restorations were constructed for five extracted teeth. Following cementation, the margins were photographed (magnification × 33) and the prints mounted to produce a continuous image of the entire margin. Cement film thickness measurements were made at 0.1-mm intervals. The five cemented restorations were then embedded in resin, sectioned longitudinally, and examined under a microscope (× 125). The mean gap at the restoration margin, as measured by each technique, was 18 μm and 19 μm, respectively. These results were consistent with the clinical impressions of cemented galvanoceramic restorations completed at the University of Tübingen.

    Full-crown restorations made by galvano forming may be considered as highly biocompatible, stable and aesthetic restorations. Therefore, they represent an alternative to conventional metal-ceramic crowns (MC), which might be associated with an allergic or toxic reaction due to metal oxides. In...
