Yes...shading of zirconia is very important. And more importantly is consistent shading. If the milling center consistently gives me the wrong shades you can only imagine the problems it...See more causes for a lab. The lab either needs to correct the shade or have the work remilled which is could delay seating of the crown.

Ceramill milling equipment allows to adjust magnification factor between 1 and 8. Regular Zirconia blanks have a shirnkage factor of about 1.250. I would like to know if there is a linear correlation between these two scales, so given a certain shrinkage factor I can easily translate it into the magnification factor for Ceramill.
