The following are “discussion-opener” responses by:

I have been using full-coverage zirconia crowns in low-aesthetic-need zones for patients who want a tooth-colored restoration. I like the fact that I can do my basic gold crown prep and keep it more conservative than a PFM or (e.g.) Emax crown.
However, other than the fact that it is tooth-colored, the only additional advantage is price. The lab fee is far lower than the fee for a gold crown or a full cast semi-precious crown. I still find that the cast metal fit is superior and recommend cast metal (preferably gold) for the best, longest-lasting restoration of a second molar.

Gold is better for function prep and many other reasons. However, the question is: will the patient accept gold? I have always given my patients the option, to which they have their own ideas and I have never been able to persuade them.
