Are they really marketing these for "bacterial resistance"? Sheesh!
There are low index porcelains available for conventional
porcelain/metal crowns. I tend to agree that I have my doubts that
Captek can be as strong as conventional PFM.
For the OP--I doubt there are any conventional casting golds that are
90% gold. Maybe someone will set me straight on this.

In my experience, Captek porcelain will wear more than
conventional PFMs. I wouldn't use them for clenchers
or posterior teeth.

Captek is good technology ... yes.

The advantage is the composition of the underlying metal, or
sub-structure.

And a bit more pricey.

Esthetics ..... forget the bacteria nonsense. It is nonsense of
course. Bacteria cannot attach to porcelain in any meaningful way. I
will give you the biochemical reasons why, but its not that
fascinating AT ALL.
What people forget is that our WORLD, everything, is covered with a
velvety covering of friendly bacteria.
Pathogens scare me, not bacteria.

I have been reading on the internet regarding Captek and full cast gold
copings.
Full cast gold copings oxidize upon firing - Captek doesn't
However if polished isn't the appearence of Porcelain fused to High 90+% gold
similar and just as long lasting?
The captek process seems to take longer for the labs to produce than the
standard PFM.
Are the only advantage cost and bacteria resistant?
Is there an advantage of porcelain fused (or pressed) to captek vs full cast
gold?
Where can I find the research behind the claim that captek is bacteria
resistant?
