Abstract
The Cera-Platin crown system using a special noble metal foil coping is well known as a new metal ceramic technique. We observed the effect of soldering and the micro configuration of the noble metal foil coping with a bunsen flame and a furnace using Renaissance Crown.
The results can be summarized as follows: I. There was no fusion, but only diffusion, with bunsen flames at 1, 000°C and 1, 050°C.
2. The pure gold layer fused, the pleats were soldered and a stable coping was formed in a bunsen flame at 1, 100°C.
3. In conclusion, there was little difference between the furnace and the bunsenflame with regard to soldering and the micro configuration of noble metal foil.
