FAQ
Q : Is the fit of crowns and bridges based on zirconia copings as good as that of PFM crowns and bridges?
A : Yes, the marginal fit of crowns and bridges fabricated from zirconia copings can be as good or better than PFM crowns and bridges.
Q : Is the fit of a zirconia coping important since the zirconia ceramic is so strong?
A: The thicker the cement the weaker the all-ceramic restoration. Cements are not as rigid as zirconia ceramic, so a thicker cement layer will cause more flexural deformation of a ceramic core, increasing the potential for fracture.
Q : Is it ok to grind on a zirconia coping without water spray?
A: Water spray is necessary when grinding on a zirconia ceramic coping. The white light or hot spot you see between a diamond and a zirconia ceramic has been measured at 1500 ºC. If the temperature of zirconia ceramic rises above 1000 ºC, a phase change can occur that will induce cracking and surface defects, lowering the strength of the coping.
