Introduction
When selecting the ideal crown for a patient, two leading materials dominate dentistry: Zirconia and E-Max. Both are excellent options, but each performs differently depending on strength needs and aesthetic expectations.
What Is the Difference?
Zirconia Crowns
Extremely strong and durable
Great for posterior teeth
Suitable for bruxers
Less translucent than E-Max
E-Max Crowns (Lithium Disilicate)
Highly aesthetic and natural-looking
Best for anterior teeth
Good strength but not as high as zirconia
Ideal for veneers and cosmetic cases
