3 things help.

We use white plus
We actually prefer GC G_CEM in B01 (white opaque resin cement)
Proper abutment design

Since you are in control of your design for patient specific abutments you need to plan for not only the quality of the split file to be reproduced by understanding machining limitations but why planning for the units most vulnerable area to hide the gray at the thinnest parts of the crown.

By really looking at dimension and shoulder radius and eventual margin line offset you can get a perfectly smooth THICK margin to the abutment/crown to hide the most challenging spots. Understanding how to selectively apply the white plus internally and how much it penetrates takes some experimenting as you just really need to be keenly aware of any thick or thin areas.

With all of the tremendously translucent multi Y zirconias value needs to be managed more than ever and slapping a dark abutment no matter how shiney the gold anodizing is often yields less than ideal results.

Plan for excellence you have the tools and the products to overcome so many challenging aspects of single unit implant dentistry today.
And if you have a concern about getting a proper fit, you can just scan the abutment after you receive it and forgo the split file/core file technique. This will ensure after the opaque material is applied that you get the correct fit.

yet we fired ceramic over titanium repeatedly on TAN abutments. that is until the ceramic started failing
Yep. And wood is not wood after it's been fired either. That's why there are some failures out there because the firing weakens the initial material integrity.

fully agree..
and I'll stop right there.

taught me how to hone an abutment back to perfection....
saved many implant cases for sure.

Can use it on the Emax also to block the dark stump?
So, the liquid is applied in the green state, before sintering, inside the crown. With that, this is not aplicable to e.max.
