Abutment question (Astra Tech Cast-to)

[Contraluz]

I have another question regarding an older implant platform...

I received, from my client, the abutment shown below as the only available option to restore the case. Has anybody worked with it? Is it 'really' Cast-to? Any compatibility with something else?

As usual, many thanks in advance!

Was that box sealed? Looks like a temp abutment to me and not a UCLA>

If that is non ox gold that part would cost a fortune.

This is the only reference I can find for it. I've never seen a cast-to that didn't have a waxing sleeve...?

Osseospeed. Nothing is 100% compatible. If you are in the usa I have astra aqua and lilac parts. A cast to will either be a plastic and gold (ucla gold adapt) or all plastic or chrome cobalt and there are some companies who make a cast to with titanium base. What part are you ideally looking for and you can email me at [email protected] to assist you further.

That was my first though, too!

Its sealed, though. A google search brought reference to a Dentsply website in Norway, but no additional info... And, I agree on the cost for a Cast-to abutment of this size...

You found the Finnish website and I found reference on a Norwegian... Maybe it is a Scandinavian thing...

No idea. I worked with a Swedish trained guy, and never heard of such a doohicky either. Could just be we never touched on needing to discuss them. I'm with John though, what in the world did that cost if it's non-oxidizing? They have in the catalog I put in the other link cast to options that are "normal".
Lead on McDuff.

This abutment was once upon a time sold under the trademark name "American Abutment" by Astra. Yes, the whole thing is cast on metal

Thank you! Well then, I will crack it open and give it a try.

Thanks!

You could also consider scanning it & fabricate a Zirconia crown then bond[emoji4]

In this case not , it is part of a three unit anterior prosthesis. The other abutment is of newer date.

Anterior!
Would you please share pics of the completed restoration if you have time?
I'd love to see how you decide to hide that massive hunk of metal behind a negligable allowance of anatomic thickness.

It will be fine. The implant is rather deep and we have enough room to play with. I will snap a few pics, as I progress.

that massive hunk of metal.

And you were worried about the abutment...

 

[lcmlabforum]

So this is full platinum?
Wow!

Tha magic ingredient in ucla alloys is often iridium that keeps the alloy from oxidizing

We used to do these all the time. Just make sure you are using a Nobel metal to cast. No biggie, You could still do a custom abutment and return it.

 

[Contraluz]

Thanks for all the input. Since it looked like a temporary cylinder and there is no real info available, I was hesitating to open the box, just like that...

I did a custom cast post with it. Worked well. I used a yellow gold alloy. It is big, though... As you can see, the screw is enormous! Will try to take a couple images before the case leaves the lab.
