Does Cerec crowns last less than the lab made ones?
CEREC crowns have the ability to be fabricated out of several types of materials. The newest is Emax, or lithium disilicate, which is an extremely strong and durable material. The longevity of this material is fantastic and has a tremendous natural tooth appearance. As far as how long they will last. If the restoration was done well, it really depends on how well you are able to take care of the crown. The better job you do with the maintenance, the longer the crown will last. A well maintained crown has the ability to last an extremely long time, in the same way that a poorly maintained crown will have a shorter longevity.
How long do CEREC crowns last?
CEREC restorations (inlays, onlays, and crowns) have a track record of over 25 years. The latest CEREC machines and computer software packages enable us to fabricate crowns with unsurpassed accuracy and precision. And, with newer materials like eMax (lithium disilicate), these crowns can be expected to last even longer than the original materials used.
One thing to keep in mind--the number one reason for crown failure is recurrent decay. Recurrent decay can happen around any type of crown or restoration, regardless of the material used and how it is made.
