IPS e.max 500 MPa

The IPS e.max you know, but even more versatile!

  • 1mm minimally invasive preparation
  • New translucency options
  • 500 MPa for maximum confidence

Ivoclar Vivadent is committed to quality at every step of the manufacturing process for IPS e.max Lithium Disilicates and as part of that commitment, we test each batch of material produced for a wide range of attributes to ensure that they meet our high standards. IPS e.max CAD has been stated to have a minimum design specification biaxial flexural strength of 360MPa and IPS e.max Press of 400 MPa. Nothing we make will fall below this value.  After 11 years and thousands of batches produced and tested, we now feel comfortable communicating new information regarding IPS e.max Lithium Disilicate.

Minimum strength values are important to know but are rarely communicated by other companies.  Ivoclar Vivadent has been conservative when reporting flexural strength data to the market, but the reality is that after 11 years of continuous quality testing, IPS e.max Press showed a mean flexural strength of 470 MPa, IPS e.max CAD of 530 MPa. IPS e.max Lithium Disilicate materials as a whole produces an average biaxial flexural strength of 500MPa.

These values help to validate the product's phenomenal success rates over the last decade. It also lends to the ability to do more conservative dentistry which benefits laboratories, dentists and patients.  Because of these proven strength values, Ivoclar Vivadent is now recommending as little as 1.0mm reduction for IPS e.max minimally invasive fully anatomical crowns when adhesively cemented.
