To really answer this question - please take a picture how you sprewed before investing. Then I can help and not only guess.

[email protected] In March we open up a trainings- and support center in Santa Ana. We also do courses not only in milling, we teach in weekly courses how to press e.max crowns from investing to finishing - incl. stain and glace technique in the most productive and succesfull way.
We start this for everybody affordable trainings program, that every e.max or lithium disilicate press material user saves time. Then all the future pressing results are predictable. E.max is a exellent material and you want believe the results before you see it in our course.
Also a DC5 milling system and all the other CADCAM products are there and we train the lab technicians in all the digital processes.
See us in Chicago and you will not be dissapointed what we introduce. We want succesfull American labs.
