TL;DR - Cut out teeth from the model, close them up - save them to your PC - run them through Exo library creator.
Any STL file with Exocad's tooth library creator can be used. You could technically get a solid STL of any type, run it through the library creator (this is an intensive process that requires you to mark out every area that the anatomy tools will move, as well as the "m/d contacts", etc) then use that. So, you could make a Mickey Mouse tooth.
I have seen a trend in the library teeth where a closed bottom mesh should be used for "pontics", and open bottom for the files that go into "teeth" in the library folder. I've only seen this oddity when bringing in a ZZ library into a non ZZ exocad, so there's a possibility their libraries are defined differently, and act differently than base exocad users. I had to actually edit mesh, and cut off the bottom of their library to get it to form properly to the margin.
