Can EMAX crowns be used on posterior teeth?

Also, since front teeth are the most visible ones, they need crowns that exactly match the adjacent tooth colour. But in the posterior teeth or back teeth where masticatory forces are heavy, all ceramic crowns, be it zirconium or E-max, should be avoided.

Which crown is best for posterior teeth?

Solid zirconia has had remarkable success for posterior crowns, particularly for patients with heavy occlusion and bruxers who prefer a natural tooth color crown as opposed to metal. And, since there is no porcelain to chip or fracture, the repair and failure rate is less than the traditional PFM.

When do you use Emax crown?

The EMAX crown is an ideal solution in correcting the following dental problems:

Teeth that are stained or discolored.
Teeth that are broken or fractured.
