Single crowns made of IPS e.max lithium disilicate can be…
3X STRONGER
than a Zirconia single unit crowns!

3. Buccal Lingual cusp loaded increasing cyclical load every 10k cycles until failure
Bottom Radial Crack

4. Fatigue Zirconia supported / Press-on
200 N 40 K
300 N 50 K

5. Fatigue IPS e.max CAD Lithium Disilicate Survivor at 900 N and 180 K cycles (profile I)

6. Only superficial damage at load surface
Fatigue IPS e.max CAD Lithium Disilicate Survivor at 900 N and 180 K cycles (profile I)
Only superficial damage at load surface

7. IPS e.max CAD Lithium Disilicate Biaxial mouth motion step stress fatigue
No Cracks - only superficial surface damage
Specimens were tested up to 900 N of force with 180,000 cycles and no cusp shearing !

8. Survival of test materials based on Load and Number of Cycles
