The PRESS technique has established itself as a state-of-the-art processing method over the past 19 years and it has become synonymous with esthetic and accurately fitting all-ceramic restorations.

IPS e.max Press are new biocompatible lithium disilicate glass-ceramic ingots. They offer the fit, form and function which is expected from pressed ceramics. In addition, they offer improved flexural strength (400 MPa).

The esthetic properties have been optimized. Creating all-ceramic restorations has been simplified and they offer true-to-nature properties like never before.

IPS e.max® CAD unites modern processing technology with a high-performance material. The lithium disilicate glass-ceramic is manufactured in an innovative technological process, unique in the dental industry.

The glass-ceramic is processed in a crystalline intermediate phase. In this "soft" state, the material exhibits its unusual "bluish" color and strength of approximately 160 MPa.

In this "blue" phase, the restorations can be manually adjusted or cut-back in a fast and efficient fashion. IPS e.max CAD acquires its final strength of 360 MPa and the desired esthetic characteristics, such as tooth color, translucency and brightness, during a simple and quick crystallization process at 850 °C. Subsequently, the crowns can be stained and glazed or veneered with IPS e.max Ceram.
