Maximize the Esthetic and Strength of Metal-Free Restorations

IPS e.max is a monolithic, lithium disilicate ceramic that delivers outstanding esthetic and precision fit. It is an affordable alternative to PFMs and zirconia-based restorations.

With IPS e.max, you can offer your patients beautiful restorations that demonstrate high mechanical strength. Its unique formulation provides an average flexural strength of 500 MPa, making it the ideal high-strength solution for single-unit anterior and posterior crowns, veneers, inlays, onlays, screw-retained implant crowns, three-unit anterior bridges, or restorations with minimum preparation dimensions.

IPS e.max is a registered trademark of Ivoclar Vivadent.

Clinicians Report® Ceramic Crown Study

Clinicians Report® — Ceramic Crown Study

After more than eight years of clinical use in the independent Clinicians Report® study (Nov., 2018, Vol. 11, Issue 11), IPS e.max CAD delivered a 95% survival rate. The 5% failure was due to a breakdown in the cementation of the crown and not the lithium disilicate material itself. When comparing this data to other glass-based products at only one year of clinical use, it is clear to see why more dentists are reaching for IPS e.max CAD.

Clinical Studies

“In [my] case, it did a great job of blocking out a dark root and a gold post. It is notable that IPS e.max has no understructure, yet it can still be cemented conventionally and block out dark stump shades.”
-Michael DiTolla, DDS, FAGD



IPS e.max is ideal for anterior single crowns, inlays, onlays, veneers and bridges up to 3 units.

Subject to the return of a device that is placed and then fails, the lab will repair or replace the device without charge for the cost of materials and workmanship or refund the original price paid, at the lab's option, for up to 7 years for glass ceramic veneers and for the life of the patient originally receiving the restoration from the date of placement for zirconia veneers. This limited lifetime performance warranty shall apply to direct end-user customers (treating clinicians) only.


Clinical Tips

Anterior full-coverage crowns require a chamfer with 1.5–2 mm facial reduction, 1–1.5 mm lingual contact clearance, 1.5–2 mm incisal reduction, 1–1.5 mm reduction at the gingival margin with rounded internal line angles; or a shoulder with 1 mm lingual reduction, 2 mm incisal reduction, 1.5 mm labial reduction, 1 mm 360° rounded shoulder.

Inlays and onlays require 1.5–2 mm isthmus width, 1–1.5 mm wide gingival floor with rounded internal line angles and butt joint margins.

Veneers require a uniform preparation and lingual reduction to increase strength. A medium-grit round-ended diamond is used to join the depth cut grooves to establish a uniform preparation and porcelain thickness of at least 1 mm. The diamond is angled to eliminate undercuts and establish a butt joint on the lingual aspect of the preparation. The incisal edge should be rounded to eliminate sharp line angles.

Chamfer Margins – Correct preparation of the chamfer margins interproximally allows the appropriate bulk of porcelain.
Adhesive bonding/dual cure materials include:
  • Variolink (Ivoclar Vivadent)
  • Choice (BISCO Dental)
  • Insure (Cosmedent, Inc.)

If an adjustment is required on the ceramic, ALWAYS CEMENT OR BOND INTO PLACE BEFORE PROCEEDING, then use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu and Vident).
