Project Description

IPS E.max®

With more than 20 years of proven experience in the business of metal-free restorations.

IPS e.max® Press is a reformulated glass ceramic consisting of lithium disilicate that delivers outstanding esthetics with a 10% increased strength of 400 MPa. Its ability to balance versatility and simplicity yields confidence when restoring even the most complicated cases. Ivoclar Vivadent’s patented lithium disilicate material is truly a revolution for the dental industry. Never before has a material been able to combine high strength, high esthetics and ease of use into one product, until now.

 

IPS e.max® is a lithium disilicate glass ceramic that has optimized translucency, durability and strength for full anatomical restorations. Due to the use of new technologies and optimized processing parameters, IPS e.max® lithium disilicate has evolved beyond previously available lithium disilicate ceramics.

 

Durability Study

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. Failures in zirconia veneered restorations are the result of a very weak 90 MPa porcelain material having chewing forces exerted upon it. The 1,000 MPa zirconia substructure remains in tact but the failure of the layering porcelain is ultimately a failure of the restoration.

With monolithic lithium disilicate, the work of mastication is being done on a 360-400 MPa 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 the 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.
