You're opening the can of worms, there.
kcdt,
Your right. Thats a large can of worms...
I now have 8 Ivobase machines utilizing 20 flask. Keeps the work flowing very well with consistent results.
The bottom line is use the technique that best fits your budget, is consistent, and provides the results
that makes you a profit.
Did see the denture that was milled by one of the presenters at Ivoclar that was mentioned on here.
Will be attending to to view and ask questions. As much as I like to play with scanning, design, and software.
I do not see that it is feasible to even consider purchasing a mill, software, etc. Time will tell...
