I've tried experimenting with it, crazy workflow involves other CAD apps as well, not only Exo... teeth were cut from PMMA arranged in 4 sections (4-3-3-4),made a ~25mm disk from Lucitone for the base. The teeth were slightly sized up in Rhino, then subtracted from the base, this gave enough "cement space" for easy fitting. Cut the base on my DWX50 with a fast 3 axis cycle, should've done it with 5 axis since there were some slight undercuts on the mesial flanges. It took way longer to finish the milled base vs. conventionally packed one made of the same material. A better mill, stock, cutting strategy prolly could've improve upon it...I dunno. Did only one specimen to try...
The teeth fit well, but too loose...it turned out that I've miscalculated the cement gap, it ended up being double of what it was intended to be...
Bottom line, the proof of concept worked, the workflow can be streamlined and there are better materials to put it into profitable production if there's enough volume.
Not this time, for us...it only makes financial sense if its a Zr all-on-4 type hybrid denture. Like this one: Ti bar and Zr teeth done digitally, acrylic work the "old school" way...
