IPS EMAX Porcelain

IPS e.max − one system for every indication

IPS e.max is a modern and innovative system which covers the entire spectrum of all-ceramic indications ranging from thin veneers to 10-unit bridges. 
It includes materials of exceptional esthetics and high strength for the press technique as well as for CAD/CAM applications.
The IPS e.max system is composed of a number of independent components. Therefore, you can choose the materials that are most suited to fulfilling the requirements of each individual case. 
The system includes an innovative lithium disilicate (LS2) material, which is suitable for fabricating single-tooth restorations, as well as a high-strength zirconium oxide material which is designed for producing long-span bridges. The fact that a common layering scheme is used together with predictable shade matching represents a considerable advantage in the fabrication of combination work.
A common layering ceramic is responsible for these outstanding results.

IPS e.max Press

Lithium disilicate glass-ceramic ingots for the press technique

The innovative IPS e.max Press lithium disilicate glass-ceramic (LS2) offers excellent fit, form and function combined with high strength of 400 MPa. The material is supplied in four levels of translucency and two sizes for maximum flexibility. The resulting restorations exhibit lifelike esthetics, independent of the shade of the preparations.

IPS e.max Press is used to produce single-tooth restorations, bridges in the anterior and premolar region and implant superstructures. Minimally invasive inlays and onlays (1 mm) and thin veneers (0.3 mm) round off the indication range.

The two investment materials IPS PressVEST and IPS PressVEST Speed are available for processing IPS e.max Press.

A wide selection of ingots is offered from which you can choose the one that suits your preferred processing technique (staining, cut-back or layering technique) and the case at hand (e.g. discoloured preparation). The restorations are characterized or veneered with matching staining materials or layering ceramic from the IPS e.max Ceram assortment. The press material for the fabrication of full-contour restorations is available in 16 A-D and four Bleach BL shades. The materials for the layering technique are supplied in group shades.

 

IPS e.max ZirCAD

Yttrium-stabilized zirconium oxide blocks

Due to its excellent final strength (>900 MPa), IPS e.max ZirCAD is the material of choice in situations where high strength is required, for example, posterior bridges.

After the IPS e.max ZirCAD framework has been milled with the inLab® or inLab® MC-XL system *, the restoration is sintered in the Sintramat high-temperature furnace. In the process, the framework shrinks to its final size. Furthermore, the homogeneous microstructure produced during the sintering process imparts the material with its typical high fracture toughness.

Subsequently, the IPS e.max ZirCAD framework is conventionally veneered with the IPS e.max Ceram layering ceramic or IPS e.max ZirPress is pressed onto it.

IPS e.max ZirCAD is indicated for long-span bridge frameworks, both in the anterior and posterior region. In addition, it can be used to fabricate primary parts for the telescope technique as well as implant superstructures and crown copings.

 

IPS e.max ZirCAD is available in seven block sizes and three shades (MO 0, MO 1, MO 2). The smaller blocks are are used to fabricate crown copings, while the larger blocks are used to produce long-span bridge frameworks or for batch processing. White lines at the transition between zirconium oxide supported restorations and the gingiva as well as excessive brightness should be prevented, as they could impair the esthetics of the result. The new coloured blocks (MO 1 and MO 2) and the colouring liquids (4 colours) for imparting colour to white frameworks (MO 0) are helpful in this respect.


Combination dentures are particularly difficult to produce. Therefore, the shade system of the IPS e.max ZirCAD blocks is coordinated with that of IPS e.max Press and CAD MO. used to fabricate crown copings, while the larger blocks are used to produce long-span bridge frameworks or for batch processing. White lines at the transition between zirconium oxide supported restorations and the gingiva as well as excessive brightness should be prevented, as they could impair the esthetics of the result. The new coloured blocks (MO 1 and MO 2) and the colouring liquids (4 colours) for imparting colour to white frameworks (MO 0) are helpful in this respect.

As a result, a sound colour basis is created for producing excellent esthetic veneering results irrespective of the IPS e.max framework material used (lithium disilicate or zirconium oxide).
