A CEREC machine is able to mill a variety of different materials, including the most common, Emax porcelain or zirconia. CEREC crowns can also make resin or telio, and composite crowns as well. Typically, these are used for temporary material only.

Emax porcelain is a porcelain that is extremely hard to break. It can handle up to 450 pounds per square inch. The average mouth will only have about 250 pounds per square inch of chewing force.

Another type of crown is a zirconia crown that the CEREC machine can mill. A zirconia crown can handle up to 850 pounds per square inch. This is great for a patient who clenches or grinds their teeth.

CEREC crowns are never made of metal. CEREC crowns are typically highly aesthetic. Porcelain is used mostly in the anterior and posterior, whereas zirconia is mostly used in the posterior, or back of the mouth.

CEREC crowns are highly exact. Because the image is blown up on a computer screen, we are able to see every little intricacy of the crown preparation and the machine can then mill a crown that is exactly made for the preparation. There is very little to no distortion in these crowns.

All in all, the most common types of material for CEREC crowns are porcelain and zirconia.
