This experimental study was to determine the fitness in each cervical margin of reusing porcelain gold alloy. The gold alloy used in this experimental study was a Au-Pt-Pd alloy (BDCG-898, Bukwang Inc, Korea) for the fabrication of porcelain fused to metal crown. Twenty-five copings were divided into the five groups. And the group A, B, C, D and E were cording successively according to the frequency of reuse to five times. Each specimen was reused without adding new metal. The experimental results were as follows: 1. The group A, B, C showed good fitness in each cervical margin. 2. The group D got good fitness in labio and linguo cervical margin, but the mesio and disto cervical margin showed more than 40 . 3. The group E showed worse fitness than the other groups in each cervical margin.
