Porcelain Strength Comparison
E.max, zirconia, and feldspathic compared by MPa (strength).
Dr. Sofia Petrova
Cosmetic Dentist
Overview
Flexural strength determines crown durability.
Key points
- Zirconia (3Y-TZP): 900–1200 MPa (very strong)
- E.max: 360–400 MPa (strong)
- Feldspathic: 80–120 MPa (aesthetic only)
- Higher MPa = stronger but often less translucent
What to do
Strength matters for back teeth and grinders. Aesthetics often matter more for front.
