e.max Case Study

For many restorations, e.max is the ideal aesthetic choice.  Its material is also reliably strong:

IPS e.max Lithium Disilicate is a high strength ceramic material with 360-400 MPa of flexural strength. When fabricated to full-contour or in a monolithic state, lithium disilicate is an extremely durable material… This strength is homogenous throughout the entire restoration.

Several internal Ivoclar Vivadent tests have demonstrated that the monolithic lithium disilicate is incredibly durable and that zirconia veneered restorations fail with less load and fewer chewing cycles.

In order to validate these findings, Ivoclar Vivadent called upon the expertise of New York University. The researchers at NYU are authorities on dental materials and have conducted numerous studies investigating the longevity and performance of a wide array of dental materials.
