Emax vs zirconia vs Lava crowns: which material should you choose?

Emax, zirconia, and Lava crowns compared for Australian patients. Aesthetics, strength, and prices at Picasso Dental Clinic Vietnam in AUD as of May 2026.

Emax (lithium disilicate ceramic) gives the best aesthetics for front teeth and premolars. Standard monolithic zirconia gives the greatest strength for molars and patients who grind. Lava (3M zirconia with layered porcelain) bridges the gap — near-Emax aesthetics with near-zirconia durability — and carries a 10-year 3M warranty at Picasso. The right choice depends on where the tooth sits and what load it carries.

When to choose each material

Front incisors and canines → Emax

The central role of front teeth is aesthetic. Emax’s translucency mimics natural enamel better than any other crown material. For young patients with good enamel and normal bite load, Emax is the gold standard for teeth 11–23.

Molars → zirconia

First and second molars carry the highest bite force. A monolithic zirconia crown at AUD 679 at Picasso handles this load reliably. Aesthetics at the molar position are not a primary concern — the teeth are barely visible.

Premolars in bruxers → Lava or zirconia

The first premolar (tooth 4) is visible in smiling but also takes meaningful bite load, especially in patients with clenching or grinding habits. Standard Emax is acceptable but may chip under heavy lateral load from bruxism. Lava provides improved core strength without sacrificing the aesthetics needed for this position.

Implant crowns → zirconia (posterior) or Emax (anterior)

Implants do not flex like natural teeth — they transfer full bite load directly to the crown. Zirconia is preferred for implant crowns in posterior positions. For implant crowns on front teeth, Emax remains the aesthetic choice.

Lava in detail — why 3M matters

Lava is manufactured by 3M (USA) — a global material science company. Two Lava variants:

  • Lava (Classic): zirconia core + hand-layered feldspathic porcelain. Aesthetically closest to Emax among zirconia systems. The layered surface can chip under extreme load — lower risk than PFM, but present.
  • Lava Plus: fully monolithic with a more translucent zirconia formulation — no layering, no chip risk on the surface layer. Slightly less aesthetic than Lava Classic; stronger.

The 3M 10-year limited warranty covers manufacturing defects — it does not cover damage from trauma or abuse. Picasso registers Lava crowns under the 3M warranty programme on the patient’s behalf.

Decision framework for Australian patients

  1. Where is the tooth? Front = aesthetics priority → Emax or Lava. Back = strength priority → zirconia.
  2. Do you grind? Yes → add strength: zirconia or Lava instead of Emax for premolars; nightguard recommended regardless.
  3. What is on an implant? Posterior implant → zirconia. Anterior implant → Emax.
  4. What is your budget? PFM is appropriate for back teeth in cost-sensitive cases. It is not inferior for molars where aesthetics are not the priority.
