Emax Layered

When a case demands lifelike esthetics with precise shade harmony, IPS e.max layered crowns deliver. A high-strength lithium-disilicate core is artistically veneered with porcelain to recreate the subtle color transitions, translucency, and surface texture of natural enamel-ideal for high-smile-line anterior work and difficult single-tooth matches.

Why clinicians choose layered e.max

  • Max esthetic control: Hand layering enables micro-characterizations and nuanced translucency effects that are hard to achieve with full-contour ceramics.

  • Natural optical behavior: The veneering ceramic used for IPS e.max systems is a fluorapatite glass-ceramic designed for true-to-nature fluorescence and enamel-like appearance.

  • Confident strength where it counts: The lithium-disilicate substructure provides ~360–400 MPa flexural strength for reliable core support.

Best-fit indications

Choose layered e.max when you need:

  • Single anterior crowns that must disappear next to natural neighbors.

  • Challenging shade matches or cases requiring custom surface texture and characterization.

(If absolute maximum bulk strength is the top priority, ROE’s comparison chart shows monolithic e.max at ~530 MPa, while layered e.max is listed at ~400 MPa—layered prioritizes esthetics over raw strength.)

Prep, delivery & workflow (at a glance)

  • Impressions: Conventional or digital accepted; same streamlined intake as other ROE restorations.
  • Preparation guidelines: Chamfer/shoulder with 4–8° taper; ~1 mm margin; ~1.5 mm occlusal plus ~1.5 mm labial/lingual clearance; avoid knife-edge/sharp internal angles.
  • Seating: Clean internal surface; cement with self-adhesive or conventional cement per clinician preference.
  • Shades: All VITA 3D-Master shades supported.
  • Typical turnaround: ~7 business days in lab (shipping not included).
  • Warranty: 2 years.

Materials

  • Core: Lithium-disilicate glass-ceramic (IPS e.max).
  • Veneer: Low-fusing fluorapatite glass-ceramic (IPS e.max Ceram) formulated for natural fluorescence and translucency.
