Ivoclar e.max® - Glass-ceramic

Ivoclar Vivadent is a company founded in Zurich in 1923. Its headquarters are in Schaan in the Principality of Lichtenschein. Ivoclar presents itself as one of the world's leading suppliers of material systems in the dental industry and supplies dentists and dental technicians.

In 2017 Ivoclar Dental announced the purchase of the Seattle (USA) based company Sagemax Bioceramics. Founded in 2006, Sagemax has since been run as an independent company by Ivoclar and continues to manufacture zirconium oxide for the dental laboratory market. Sagemax Zirkon NexxZr thus complements the Ivoclar product range.

Ivoclar IPS e.max® CAD

e.max lithium disilicate, like e.max ZirCAD, is part of the Ivoclar all-ceramic system IPS e.max. The e.max glass-ceramic is also differentiated according to the manufacturing technique. Ivoclar offers the material both for the press technique (IPS e.max Press) and for fabrication using the CAD/CAM technique (IPS e.max CAD).

Like the materials VITABLOCS® TriLuxe forte and 3M ™ Lava ™ Ultimate, Ivoclar IPS e.max® CAD is sold in blocks. Originally, e.max® was only intended for single tooth restoration and the blocks were accordingly small. The e.max® product portfolio was later expanded to include larger blocks, which make it possible to mill bridges with up to 3 units. Thanks to the IPS e.max® CAD Veneering Solutions, long-span bridges can also be fabricated from e.max with support of CAD / CAM.

The e.max® material is characterized above all by a high level of aesthetics and high strength.
Did you know? IPS e.max® CAD is the world's most sold CAD / CAM glass-ceramic.1)
As with Ivoclar IPS e.max® ZirCAD, the tooth shade for Ivoclar IPS e.max® can be determined with the Ivoclar Shade Navigaton app.

With IPS e.max CAD, Ivoclar offers three solutions for maximum flexibility:

IPS e.max® CAD Monolithic Solutions

According to the manufacturer, the e.max® Monolithic Solutions material is approved for veneers, inlays, onlays, partial crowns, crowns in the anterior and posterior areas as well as for 3-unit bridges in the anterior area and in the premolar area up to the second premolar as the terminal pillar.

IPS e.max® CAD Veneering Solutions

In addition to crowns and smaller bridges, the IPS e.max® CAD Veneering Solutions can also be used to fabricate wide-span bridges. This material is a combination of lithium disilicate and zirconium oxide.

Crowns and multi-unit bridges

OUR CONCLUSION

Ivoclar IPS e.max® CAD is very popular for the aesthetic restoration of single teeth. The material is particularly antagonist-friendly and offers the patient a natural chewing sensation. Thanks to the latest CAD/CAM technology, the material is also easy to process and offers great potential for added value in your laboratory.
