Dan Butterman I get asked this question a lot from prospective CEREC owners and new user, the reason is that many of us have seen bad CEREC margins over the years. My answer is that this is no different than good and bad lab crowns. If I prep appropriately and take a good impression, likely the lab or my CEREC will be able to produce a good result. The opposite will be true if I don't.
The reason this site, basic or level 1 training, and level 2 training is so important for all users is that it not only teaches you to use the software, but how to prep, design and bond for success. It really doesn't take any more effort to get a great fitting restoration instead of a bad one, but it does take education.
The Dentist that did the CEREC crown on the left used a similar machine as mine, and took about the same amount of time to make his crown as I did for the one on the right. The difference is that he simply didn't know what the machine needed to give him a great result. If you're new to CEREC or not getting great results, get the education you need from cdocs and the results will be there. Sorry for the commercial, but I really believe strongly in the education available here.
