Emax

"Pressed" all-ceramics have been successfully used for 20 years and are synonymous with aesthetic, accurately fitting biocompatible restorations. Experience the versatility of IPS e.max Press lithium disilicate glass ceramic. It offers the fit, form and function expected from pressed ceramics. In addition, it exhibits a unique strength of 400 MPa and outstanding esthetics.
The material is available in four levels of translucency, 16 shades and 4 bleach shades therefore, natural- looking esthetic results can be achieved irrespective of the appearance of the prepared tooth. As a result, you can use the aesthetic all-ceramic IPS e.max Press even if your patients have devitalized teeth or cast core build-ups. The overall lifelike, esthetic result of an all-ceramic restoration is influenced by the following factors:

Shade of the preparation,
Shade of the restoration (ingot/block, layering material)
Shade of the cementation material

In order to facilitate the reproduction of the desired tooth shade, the shade of the preparation is determined with the help of the IPS Natural Die Material shade guide. If you require one of these please contact us. This enables the technician to fabricate a model die similar to the preparation of the patient, on the basis of which the correct shade and brightness values of the all-ceramic restoration may be selected in order to recreate the natural esthetic appearance.
IPS e.max Press can be used to fabricate restorations which preserve as much of the natural tooth structure as possible, such as inlays, onlays, Table Tops ("occlusal veneers") and Thin Veneers. You can preserve much of the tooth substance if you use IPS e.max Press, since a minimum thickness of just 1 mm is required for inlays and just 0.3 mm for veneers. It can also be used for bridges when pressed onto a zirconia framework. Zirconia is presently the strongest all-ceramic avail- able for dental applications, it is additionally characterized by excellent biocompatibility. When e.max is pressed onto our zirconia frameworks is one of the strongest and asthetic restoration materials currenty available.

Emax Lithium Disilicate Questions and Answers

There are many questions to ask yourself when choosing crown and bridge materials. IPS E.max® from Castle Ceramics is the next generation of crown and bridge materials that answers “Yes!” to all the questions.

IPS e.max® is a full contoured, pressed lithium disilicate restoration that features a variety of design options, high strength and “Empress-like” aesthetics. Best of all, like the rest of our products, IPS e.max from Castle Ceramics is 100% made in the UK.

Cement or Bond?

E.max gives you the freedom of choice. If you prefer to cement go ahead. Looking for a stronger crown to tooth interface for a short clinical crown length E.max is bondable. The fit is etched in the lab for 20 seconds. Best materials for luting are: Rely-X Unicem (3M Espe) Variolink (Ivoclar) Nexus (Kerrs)

Anterior or Posterior?

E.max uses the strongest pressable glass ceramic ingot available with a flexural strength of 400 MPa’s. So it’s strong enough for the posterior. If it’s aesthetics you’re looking for, different ingot opacities and cutback techniques make it possible to rival the esthetics of Empress.

Milled or pressed?

CAD/CAM design and wax milling provide accuracy. Pressed technology delivers the maximum flexural strength available.

Crown or Bridge?

Case selection is critical for long term success. Small 3 unit bridges only. For peace of mind Emax pressed to a zirconia framework is best. Smaller connectors, cantilever designs and longer span/unit bridges can be achieved with predictability when Emax is pressed onto a zirconia framework anterior and posterior.

Veneer or Thin Veneer?

Yes! You read right. The lithium disilicate material can be pressed as thin as .3mm and is an excellent option for those minimal or no preparation cases.
