IPS e.max Press Lithium Disilicate: versatile and esthetic

Experience the versatility of IPS e.max Press lithium disilicate glass ceramic (LS2). It offers the fit, form and function expected from pressed ceramics. In addition, it exhibits a unique strength of
400 MPa and outstanding esthetics.

IPS e.max Press is a lithium disilicate glass- ceramic ingot for the PRESS technology. The production process creates absolutely homogeneous ingots in different translucency levels. These ingots feature a strength of 400 MPa and are thus the pressed ceramic ingots with the highest strength. They are pressed in Ivoclar Vivadent press furnaces to produce restorations with out- standing accuracy of fit. The pressed, tooth-coloured, highly esthetic restorations are stained and/or veneered with IPS e.max Ceram and glazed.

Indications

– Table tops (occlusal veneers)

– Thin Veneers

– Veneers

– Inlays

– Onlays

– Partial crowns

– Crowns in the anterior and posterior region

– 3-unit bridges in the anterior region

– 3-unit bridges in the premolar region up to the second premolar as the terminal abutment

– Pressing over electroplated single-crown frameworks

– Implant superstructures for single-tooth restorations (anterior and posterior regions)

– Implant superstructures for 3-unit bridges up to the second pre- molar as the terminal abutment

– Primary telescope crowns

Glass-ceramic restorations no longer need to be seated with the adhesive technique at all costs. It goes without saying that the adhesive cementation, for example using Variolink® II,continuestobethe“goldstandard”inall- ceramics, that it convinces users with outstanding bonding values and that it has proven its worth in successful long- term studies.
Multilink® Automixisauniversalself-etchingcomposite system which can be applied without prior mixing. The Multilink Primer seals the dentin and provides a sound marginal seal as well as high bonding values. Nevertheless, a trend towards less complex cementation systems has been observed lately. If you have to cement IPS e.max Press crowns and bridges, you can either use the adhesive, self-adhesive or conventional technique – the choice is yours.
The application of the new resin cement SpeedCEM is even easier than that of conventional cements and does not require a separate bonding agent. Vivaglass® CEM is an esthetic glass ionomer cement for the conventional technique. Both products are suitable for the cementation of high- strength all-ceramic restorations (ZrO2 and LS2).
IPS e.max Press restorations are generally etched before they are seated. However, silanization is not required if the conventional cementation technique is used.

 Occlusal adjustments after the placement of the restoration are made with a (fine) diamond. A diamond polishing system (e.g. OptraFine) is used to efficiently polish restorations to a final high-gloss finish.
