E-Max Crowns
Emax crowns are one of the top choices for dental restorations due to their excellent aesthetics, durability, and biocompatibility. Here’s a breakdown of their performance:
1. Aesthetics
* Natural translucency: Emax crowns are made of lithium disilicate, which closely mimics natural teeth.
* Customizable color: They can be color-matched to blend seamlessly with surrounding teeth.
2. Durability & Strength
* High strength: With a flexural strength of 400 MPa, Emax crowns are strong enough for front and premolar teeth but may not be ideal for high-pressure molars.
* Fracture resistance: Less prone to chipping compared to zirconia crowns, but still not as strong as full-zirconia options.
3. Longevity
* With proper care, Emax crowns can last 10-15 years or more.
* Requires good oral hygiene and regular dental check-ups.
4. Biocompatibility
* Non-metallic: No allergic reactions or gum irritation.
* Preserves more natural tooth structure: Less tooth reduction is needed compared to other materials.
5. Limitations
* Not ideal for bruxism patients (those who grind their teeth).
* More expensive than metal-ceramic crowns.
* Limited use in high-stress areas (molars under extreme chewing forces).
Emax vs. Zirconia
* Emax: Best for front teeth due to superior aesthetics.
* Zirconia: Stronger and better suited for molars but slightly less natural-looking.
