Has anyone worked with Ankylos implants?
An indexed screw has some type of notched implant platform or head to it (almost all implant systems do these days). Ankylos don't, they spin around like the room does after a night of too much drinking!!!!!! Hence why a jig has to be fabricated, which isn't a problem, I usually always fabricate one anyways but it's the fact that the Dentist 'must' use it or they'll never know where to seat the abutment correctly.
All of our bone level implants go out with a seating jig. I can't imagine trying to get past the tissue to engage an implant that's that deep.
One technique is for the Dr to place the stock abutment intraorally.He then fabricates the seating jig with light cure.
The jig can now be sent to the lab with the abutment however there is no need to take a final impression.
The lab connects the analog to the abutment.Then the study model is modfied to receive the jig with the abutment/analog assembly.
By grinding a socket into model with a carbide, the analog is positioned with the jig and luted into place with resin or light cure composite.
You now have a working model.

I have a client that does this with every fixture not just ankylos, they make a jig at the time of surgery with a standard transfer assembly. We modify the preop model as described and fab a custom abutment/temp crown to train the soft tissue. We fabricate a duplicate die of the custom abutment that the OS sends to the restoring doctor so they can take a standard Crown and bridge impression for fabrication of the definitive crown. This allows the soft tissue to be maintained and not disturbed trying to retract it to capture margins.
John are you fabricating custom abuts for Ankylos?
NO,
Luckily for me Ankylos is not very popular out in my neck of the woods. Its my understanding that there isn't a cad/cam system doing these yet ???
My post was just adding to the statement of how to utilize a jig from a one stage surgery for a predictable outcome.
Sorry if I hijacked the thread, I was just trying to add info.
