You have to always plan for a weak link. You have to know where the
eventual failure will occur. If you engineer the failure point into right
part of the restoration, you get the privilege of redoing the restoration
over the next 40 years, rather than eventually extracting the tooth. With a
metal crown coping, I would want the porcelain to wear down. If the
porcelain is too strong, parafunctional forces force the failure down to the
CEJ.

I'd prefer neither of these, SIR!! I don't know the newer low-index
porcelains, and while I'd heard they were less destructive to natural
dentition I hadn't heard that they actually were softer than natural
enamel. Certainly I'd rather wear the restoration than the tooth.

Sorry to hear of your bad experience. I haven't used them, and the
marketing seems to imply superior fit and strength when compared to
all-ceramics. Otherwise, why use them? How did they fail?

Maybe I did something wrong, but I doubt it.

The Captek crowns and bridges that I have done have *not* given
the durability and longevity of conventional porcelain fused
to noble metal.

Looking good for 'a while' doesn't cut it for me.
