ACE DNTL STUDIO

E.max vs Zirconia Veneers

E.max (lithium disilicate) and zirconia represent two distinct material categories. E.max is glass-ceramic with high translucency, ideal for visible-zone aesthetic cases where light passes through the restoration the way it does through natural enamel. Zirconia is polycrystalline ceramic with extreme strength but historically limited translucency, ideal for posterior cases under high occlusal load or for masking severely discoloured underlying teeth. ACE DNTL STUDIO selects per case rather than per default. Hand-layered Signature porcelain layered above an e.max substructure is the studio's flagship for anterior aesthetic work. Pricing per unit: pressed e.max from €600; layered zirconia or Signature porcelain from €900. The price difference is layered ceramic labour, not the substructure material itself. Material choice is decided by clinician and ceramist together based on the specific clinical case.

Which is stronger — e.max or zirconia?
Zirconia is significantly stronger. Lithium disilicate (e.max) sits at around 360 MPa flexural strength; full zirconia ranges from 800 to 1100 MPa depending on the formulation. For posterior load and bridges, zirconia wins on strength. For thin anterior veneers where brittleness is rarely the failure mode, the strength difference is academic.
Which has better translucency?
Lithium disilicate (e.max) has historically held the translucency advantage, with newer generation high-translucency e.max producing very natural light transmission. Traditional zirconia was opaque; modern multilayer zirconia and layered zirconia systems have closed the gap substantially. The real-world translucency winner depends on the specific brand and generation, not the category.
Why does ACE DNTL use a layered zirconia system rather than e.max?
ACE Signature porcelain — the studio's flagship material — is a hand-layered ceramic system over a zirconia substructure. The combination produces both the strength of zirconia and the optical depth of layered porcelain. Pure e.max veneers are excellent restorations and remain in the lab's toolkit for cases that suit them. The signature system is the default because it matches the studio's bias toward longevity and optical depth in the same restoration.
Will an e.max veneer last as long as a zirconia veneer?
Both can last fifteen to twenty years in well-placed anterior cases. The longevity difference between materials is smaller than commonly assumed when both are placed by competent clinicians on adequately-prepared enamel. Material is only one variable in long-term outcome — preparation depth, bonding protocol, occlusal balance, and structured review matter at least as much.
Can I tell the difference between e.max and zirconia in my mouth?
Functionally, no. Both feel like normal teeth. Optically, the difference depends on the specific material generation and the lab's layering work. A skilled ceramist can produce excellent aesthetic results in either material. An unskilled execution in either material reads as ceramic.
What exactly is e.max — chemically?
Lithium disilicate — a glass-ceramic. Crystals of lithium disilicate suspended in a glass matrix. The crystal structure is what gives e.max its 360 MPa flexural strength; the glass matrix is what gives it its translucency. Marketed as IPS e.max by Ivoclar Vivadent. Manufactured as either pressed (stronger) or CAD/CAM blocks (slightly weaker but milling-friendly).
