Porcelain Strength Comparison

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.

Practical decision guide

Dental materials should be chosen for the tooth, bite force, aesthetics, allergy history, repairability, and maintenance needs. A premium material in the wrong indication is still the wrong choice.

Check this first

• Tooth location, remaining tooth structure, grinding, smile visibility, gum line, allergy history, and whether the material can be repaired or replaced.
• Whether the restoration is temporary, direct, lab-made, screw-retained, cemented, removable, or implant-supported.
• Manufacturer, lab, shade selection, warranty, and maintenance requirements.

When to book sooner

• A restoration feels high, loose, rough, cracked, smells odd, or traps food.
• You have a metal allergy concern, kidney disease, pregnancy, or another factor that affects material choice.
• The quoted material is unclear or the clinic cannot explain why it suits the case.

Topic-specific notes

• For material choices, ask why that material fits the tooth location, bite force, aesthetics, allergy history, repairability, and expected lifespan.

Questions to ask at the appointment

• Why is this material better for my tooth than the alternatives?
• What is the expected lifespan and most common failure mode?
• Can this material be repaired, polished, replaced, or matched later?

Dubai patient note

Dubai quotes should identify the material system or implant brand when relevant. Ask for the lab certificate, implant passport, warranty terms, and maintenance instructions after placement.
