Tyler let me give you one suggestion on this case if your going to help this guy out, and the model has not been verified.
If I was a betting man I would say the most ant fixture will need to be angle corrected. Make sure your verification jig has an eng interface for this offending fixture. This way you have way more prosthetic options if you are certain that the internal hex is orientated correctly on your master model. this could be very handy just in case you go with transversal screw-retained abutment for this fixture. The rough part with straumann is there is no simple angle corrected multi unit transmucosal like many other systems have for this fixture. They have them for the bone level but not tissue level .
The fact that the foundation seems flawed by what a couple of pictures show may only be the beginning of the head aches. You will know more once the model is verified and bite relation is done and you can then digitize and come up with a plan.
Another hurdle is since they are tissue level fixtures they are high, sealing the airway in the maxilla and keeping the base convex is all but impossible with cad bases that are FDA cleared. If you were to do a NT TRADING TWO CONNECT case their abutments will raise the restorative platform even higher which makes it tougher, The ti cap will then be cemented even higher in the ZI making the base that much more concave.
To complicate things even more is the fact that Straumann is so militant on using no 3rd party parts. Using their synocta abutments on a case like this but doing a Zirconia bridge where you cement a casted cap would be a fortune in parts cost. I would say at least 3 times the fee.
If we were out of FDA land there are way more options out there to make our life easier (DESS) but thats an entire other can of worms to open.
Good luck.
