IPS e.max CAD

IPS e.max CAD is the world's best-selling glass-ceramic1. It is suitable for the efficient fabrication of full-contour restorations and it is known for its versatile application options, comprehensive range of indications and for its high strength of 530 MPa2.

Both its esthetic properties and durability have been confirmed in everyday clinical practice. As a result, the material can be used to fashion full-contour crowns of only 1-mm thickness, which are subsequently seated with the adhesive technique.

Glazing
IPS e.max CAD Crystall./ Shades/Stains and Glaze is a universal range of stains and glazes. The glaze is available in two versions - with or without fluorescent effect. Minor corrections (e.g. proximal contact areas) can be applied to IPS e.max CAD restorations using IPS e.max CAD Crystall./Add-On.

Comprehensive range of applications
A wide variety of restorations can be produced with these materials – from thin veneers to three-unit bridges (up to the second premolar as the terminal abutment). High esthetic standards are fulfilled due to the four different levels of translucency of the A-D shades and the special Bleach and Impulse shades.

The IPS e.max CAD and Telio CAD range comprises blocks that come with a pre-fabricated interface for the direct cementation to a titanium bonding base, e.g. Dentsplay Sirona TiBase. This allows implant-supported hybrid abutments and hybrid abutment crowns to be created at chairside using clinically proven products3-8. Cementation is achieved with the self-curing Multilink Hybrid Abutment luting composite.

IPS e.max CAD HT (High Translucency) - The minimally invasive block
Given their high translucency which is similar to that of natural enamel, HT blocks are ideal for the fabrication of small restorations (e.g. inlays, onlays). Restorations made of HT blocks convince user with their true-to-nature chameleon effect and the exceptional adaptation to the remaining tooth structure.

IPS e.max CAD MT (Medium Translucency) - The bright block
MT blocks demonstrate medium translucency and are used for restorations that require more brightness than HT restorations and more translucency that LT restorations.

IPS e.max CAD LT (Low Translucency) - The versatile block
Given their low translucency which is similar to that of the natural dentin, LT blocks are ideal for the fabrication of larger restorations (e.g. posterior crowns). Restorations made from LT blocks convince users with their lifelike brightness and chroma. This prevents the incorporated restorations from greying.

IPS e.max CAD MO (Medium Opacity) - The classical block
Given their particular opacity, MO blocks are ideally suitable for the fabrication of frameworks on slightly discoloured preparations. They are primarily used in the dental laboratory.

IPS e.max CAD I (Impulse) - The opalescent block
The Impulse block enable the fabrication of restorations with pronounced opalescent properties. The opalescent blocks are available in two versions with different opalescence values (Opal 1 and Opal 2). The blocks are suitable for veneers in light tooth shades, which require an opalescent effect.
