Pre-Sinter Staining Pontics

[sirmorty]

Hey Guys,

Does anyone have any tips for getting better results on pontics?

I'm using Zirkon Zahn Aquarell
I find that the pontics are a too bright and white and seems to absorb the liquid a bit different.

I know it's because it's a large chunk of Zirconia and not thin compared to the abutments.
But I find it I put more pre-sinter stain on the pontic area , The colour becomes more intense but it is still does not really correct the brightness/white issue.

I'm pretty happy with the results I get on the single crowns.

What zirconia are you using?

are you dipping under vacuum?

 

[sirmorty]

The Zirconia is Wieland Zenostar.
I'm hand brushing, no dipping.

It's one of the issues water based stains have on dense zi. Acid based do not seem to have the same issues

Dilute the stains for the pontics...

Change your Zi and get into a system that works well for you.
It's tough to develop a recipe .... No economics in development

Thanks for the reply's

Like you say it's a little bit tough to just start changing everything, especially when you have lots invested on the stains/zirconia.

Maybe I will look into acid once I'm finished with the Aquarell.

What is the technique about under a vacuum?

In use a chroma inhibitor on Pontic areas


If you never make a decision then your possibilities are endless.

Double refined fine snake oil...

just do more brush strokes on pontics we have been using aquarrell since it came out .we refined our technique on left over thick pieces from the puck we also use prettau.maybe that's why it works ok same on same ,hope this helps we found we got better colours with water based rather than acid based.

I took your advise and switched into a Zi system that works for me!
I switched over to Jensen's new XT Zirconia a few months ago and its the first zirconia that I have used where I get even distribution of shade from abutted teeth all the way through the thicker pontic areas.
No longer do I see a difference in shading or lack of shading on the pontics. It seems to be working using the brush on liquid technique as well as the dipping technique. Plus its a beautiful translucent zirconia, added bonus!

We use the Argen Zirconia with their colour system. They have 2 incisals, and a chroma inhibitor for the pontics or thick area's (these are made by them). For dipping the shade they use the ZirkonZahn water based liquids, so this might be an easy switch for you.

You paint on your incisal if you want it. Then paint on 1 brush stroke of chroma inhibitor on pontics, etc... then dip the shade. Super easy, super fast.

It works, and we are happy.

I love acid stains. You can dip em, walk away and forget about him. 2 hours later pull em out, their just fine. Dip a bridge with giant pontics. No problem.

What?

Certainly you know what a vacuum is? Do you mix stone under a vacuum? It sucks the air out.. Im just bein a smartas s.. I remember seeing mark jackson made this big contraption with small jars to colorize under vacuum.. its gets those hard to reach places.

Sounds as practical as electric scissors. I'm curious to see the difference between the two, vacuumed and normal.

I know the Bruxzir material didn't take color well so they introduced a vaccum to it to help get the color in. I use Zenostar and have zero issues with coloring it or pontics being too dark. I've used three or four different stain systems, and after fiddling around with them, I've been able to good accurate shades with each.

What is chroma inhibitor?

Hi Stumpf, A chroma inhibitor is a poly glycol mixed with other liquids that inhibits the color from penetrating into the monolithic as far. It has a sorta B1 coloring to it that can highlight the incisal.
