[QUOTE="BobCDT, post: 50188, member: 3119"] Hi, Unfortunately, I spent over $100K for Cerec. Sold it for $17K. It does not work well in a lab environment. Dentists need to prep teeth to accommodate the mill. They will do this if they own (and have to pay a mortgage on it). however, you are not going to get your docs to prep correctly for quality Cerec results. When it come to milling e.max the diamond tools chip the margins. This is not once in a while. It happens on most cases. If you move to Cerec milling of e.max you will need to be routinely repairing margins before shipping cases. I don't know about you, but I am not sending out new cases with repairs. Furthermore, emax is stronger, fits better and cost less to press. I don't understand why lab would want to mill it. When I comes to milling zirconia there are much better, cheaper and versital systems out there. One last important point. When milling zirconia we cut the material with carbides. When using Cerec you grid the material with diamonds. I believe the difference between cutting and grinding zirconia is quite significant. In conclusion, DON'T put a Cerec system in your lab. It's junk!! If you have any interest in providing good quality prosthetics I gaurentee a year form now we will be telling you "we told you so". Please keep in mind, I do feel qualified to respond to this post as I own many mills that give us great results on a daily basis. I have never used the E4D so I can't comment on it. Bob [/QUOTE]
