In this study, We tried to find out the fracture strength of zirconia coping all ceramic crown and
collarless porcelain fused gold alloy crown as the compared group. Each of the collarless porcelain fused gold crown and zirconia all ceramic crown has been produced specimen 10 each. And after pasting them on the steel jig, it had load given at porcelain incisal edge by 130 and measured fracture strength by Universal Testing Machine and then We have results from that.
1. The average value of fracture strength suggested 950.49 N at collarless porcelain fused gold
alloy crown, 656.81 N at zirconia coping all ceramic crown.
2. Fractured pattern showed that the whole of labial part was exposed in collarless porcelain
fused gold crown, but porcelain of margin part did not show fracture in advance. In the practice, the concern that collarless might cause fracture strength to be weaken does not matter, we concluded zirconia all ceramic crown made fracture that only a part of labial porcelain was fractured. The combination of zirconia all ceramic crown and turned out to be excellent.
