Thanks for your two series of discs , I have nearly completed the Posterior course and I am waiting to view the Anterior course. CEREC Made Easy should be renamed CEREC Made Excellent. I particularly enjoyed your technique for getting a correlation image when prepping the last tooth in the arch. I find that if one keeps the margins away from the gingiva and uses a rubber dam clamp the software has more points to help it correlate. The one caution is to leave the horizontal portion of the clamp out of the image otherwise the software sets the occlusal height at the height of the clamp. The one anterior tip I have found useful is to get the patient to close and powder the prep with the lower teeth in position . This avoids a black area behind the prepped teeth and gives you the bite at the same time.
Your course has really helped me raise the quality bar for my CEREC's!
