Do you seal your Dies For Zirconia?

tonester · Oct 12, 2011

I know you don't seal dies before scanning but I'm wanting opinons on sealing dies after sintering and before fitting. Do you think it's necessary or is it a waste of time?

charles007 · Oct 12, 2011

Tony, are you having to grind to seat your zir crowns ?

tonester · Oct 12, 2011

Charles,
Not much, somtimes not at all, and far less than metal.

JOE_Z · Oct 12, 2011

I do. Along with the contact to reduce abrasion to the model during fit and finish

paulg100 · Oct 12, 2011

sure do. Even with fuji rock that been set under pressure (makes it harder) i still seal, i wanna make as sure as possible that i retain the marginal integrity of the die.

I seal before scanning. Your scanner should be able to scan just fine with die seal on it.

paulg100 · Oct 12, 2011

depends on the scanner

if its craplab then it wont.

then again that thing wont scan properly with out sealer either :flame:, OK i wont start :rant:

Dude, you gotta let it go, this InLab things gonna eat you up.

Cut the Clear coat 50/50 with solvent.

Experiment with ratio to "get just under " shiny results.

It will flow into the stone better and still provide the extra stregnth for no chipping at margin, but obviously you don't want it to add to the dimentions of die or to be shiny for scanning.

What's up, all my crowns that come back from my milling lab never need to be touched to seat........is my scanner more accurate than others ?
What is a good die sealer product that's ok to scan.

tonester · Oct 13, 2011

Charles, I haven't donre enough yet but fits are good. I'll keep you posted and hopefully I have the same results you're having.

Are you using 3Shape?

What are your margin settings? I am still not happy with my margins?

From Delcam and 3Shape, never touch to seat....

Will check later for margin settings.

maybe your eye sight inst what it used to be charles?

Nah, i just got back from a day at renishaw, delcam where there also.

Liking the look of there new software. Which Delcam scanner did you buy again charles?

They said they will begin phasing out the Imetric in place of their new scanner, so what was that...wait for it.... a rebranded Solutonix

those things are everywhere now.

Even the old Imetric looks to be very accurate compared to the other last gen scanners so im not suprised your getting good fits.

I got an STL of a model scan from the solutonix, im just off to chuck it into geomagic qualify and see what sort of data it puts out.

overall Delcam looks like one to keep an eye on. I liked the look of what i saw, in terms of software also.

Just to clarify we are not "phasing out" the iMetric, we are just adding another scanning option to our dental solution.

Also glad you found the visit to Renishaw useful.

What is the new option ?

paulg100 · Oct 18, 2011

The Solutonix charles.

and yeah it was a worth while day Alex.

There seemed to be a lack of BS in the air, which was a refreshing change from most other CAD/CAM companies.

BTW the STL file you gave me was the frame design, i really needed the model

but never mind.

Once i am in a more serious position to buy a new system, ill bug you for more info nearer the time. The price point you are comming in at with the new scanner is very competitive also.

Good to see you here, just as well i didnt slate your system
