Question:
I'm restoring a maxillary all-on-6 case where another provider placed the implants several months ago. He buried the implants and I recently uncovered the implants and placed healing abutments. He gave me the angulations to expect and I ordered the corresponding multi-unit abutments.
My concern is with the internal hex's and whether the hex's will be lined up correctly for the angled multi-unit abutments.
Since the implants are now osseointegrated and I cannot rotate the implant/internal hex, do I basically just have the hope for the best at this point that all the hex's are in a good position for the angled multi-unit abutments?
Answer:
That is pretty much exactly what happens at this point. Ideally, when the implants are placed, the multi unit abutments are tried on and fine tuned for ideal angulation. This makes life so easy as far as restoring goes.
However, if the implants were placed and left buried, you basically are just hoping that they line up well with the parts that you have on hand.
One surgeon told me "You don't have to be smart, if you have a big inventory."
That means that if you have many multi unit angles and orientations and heights, you will be fine. But if you only order what you think you'll need, you might have to reappoint the patient for this particular case. No HUGE deal, but that is a possibility.
Also you can use little tools like this:
to help make your job a little easier. It basically is inserted into the implant and shows you what the angle correction looks like.
