Roland has a time conversion kit (maybe a different name?) that allows you to pour up your own acrylic you'd use for normal dentures into a mold. From there you mount it like any puck and mill in the material you're comfortable with. Haven't actually seen it in practice personally, but aside from some sensitive pouring technique and I'd imagine a pressure pot, it seems to work quite well for some. Then you get the added benefit of an acrylic look you're used to.
Then with Exocad, use the Vita Vionic digital denture teeth if you have enough room, and you shouldn't have any trouble with seating them into the socket.
