Preparing for cementation Firing parameters Combination table

Nearly 20 years ago, IPS Empress revolutionized the processing of ceramic and thanks to its many advantages, such as aesthetics, IPS Empress has been established as the "benchmark". More than 33 million restorations fabricated of IPS Empress throughout the world and the use of "IPS Empress" as a synonym for all-ceramics speak for the durable life-like appearance, the ongoing success, and the high quality standard of the material.

In addition to the tried-and-tested PRESS technology, the CAD/CAM technology has also developed in the area of all-ceramics. In order to supply the "benchmark" for this technology as well, the future IPS Empress System will comprise products for both processing technologies. You will be able to beneﬁt from roughly 20 years of clinical experience and convincing aesthetics, irrespective of whether the restorations were fabricated with the PRESS or CAD/CAM technique.

IPS Empress Esthetic is available for the PRESS technology, while IPS Empress CAD

is used in the CAD/CAM technology. Both products consist of the highly aesthetic, leucite-reinforced glass-ceramic that has been clinically tried-and-tested for many years. The two ceramics are characterized by excellent strength values and outstanding aesthetic appearance. They may thus be used for the fabrication of fully anatomic single-unit restorations, such as inlays, onlays, veneers, and crowns.

Both products may subsequently be stained and/or glazed using IPS Empress

Universal Shades/Stains, or individually veneered using the IPS Empress Esthetic Veneer layering ceramic.

In this way, the IPS Empress System will remain synonymous for highly aesthetic, fully anatomical all-ceramic restorations, irrespective of the processing technology.

Material

IPS Empress CAD is used for the fabrication of highly aesthetic, fully anatomical single-unit restorations by means of the CAD/CAM technology. IPS Empress CAD blocks are made of a leucite-reinforced glassceramic which consists of a glass and a crystal phase. Leucite crystals of few microns evenly grow in a multi-stage process directly from the amorphous glass phase. During the fabrication of the blocks, the semi-ﬁnished product in powder form is pressed to blocks in a fully automated procedure, which enables a maximum of homogeneity. Given the difference in the coefficients of thermal expansion (CTE) between the glass phase and the crystal phase (leucite), cooling after sintering produces compressive stress in the glass phase. This mechanism results in an increase in strength and enables IPS Empress CAD to achieve a ﬂexural strength of 160 MPa. This type of material has been successful, as well as proven. for almost 20 years. The milled restorations feature excellent accuracy of ﬁt and a homogeneous surface. Subsequently, the restorations may be stained using IPS Empress Universal Stains and/or veneered using IPS Empress Esthetic Veneer.

Uses

Indications

IPS Empress CAD blocks can be used for the following adhesively cemented restorations. Depending on the type and size of the restoration, the respective HT (High Translucency), LT (Low Translucency), or Multi Block is recommended. IPS Empress CAD restorations may be cemented either polished, stained/glazed, or veneered.

For further processing of IPS Empress CAD restorations, users have the following options: – Aesthetic characterization and glazing of fully anatomical restorations using IPS Empress Universal

Shades, Stains, and Glaze pastes.

– Aesthetic veneering in the incisal third of reduced restorations (veneers and anterior crowns) using

IPS Empress Esthetic Veneer materials

Contraindications

– Bridge reconstructions – Conventional cementation – Very deep, subgingival preparations – Patients with severely reduced residual dentition – Bruxism – Fully (circularly) veneered anterior and posterior crowns using IPS Empress Esthetic Veneer

Important processing restrictions

Failure to observe the following restrictions may compromise the success achieved with IPS Empress CAD: – The fully anatomical IPS Empress CAD restorations must not fall below the required minimum

thickness

– The reduced (cut-back) IPS Empress CAD restorations must not fall below the required minimum

thickness – The maximum layer thickness of IPS Empress Esthetic Veneers layering materials must not be exceeded – IPS Empress CAD restorations must not be stained using materials other than IPS Empress Universal

Shades, Stains, and Glaze – Powder materials must not be mixed with paste materials – The blocks must not be milled in a non-compatible CAD/CAM system

Side effects

If patients are known to be allergic to any of the ingredients of IPS Empress CAD, the material should not be used.

Block concept

IPS Empress CAD Blocks

The shading and translucency control of the IPS Empress CAD Blocks is based on a newly developed translucency concept built on the A-D, Chromascop, and Bleach BL shade guides. The IPS Empress CAD Blocks are available in two degrees of translucency and as a polychromatic block. The blocks are precisely coordinated with the respective indications and thus enable excellent shade match with the corresponding shade guide. Depending on the indication, the blocks provide a true-to-nature chameleon effect, life-like brightness value, or a natural shade transition.

IPS Empress CAD HT (High Translucency)

These blocks are available in the 9 most popular A–D shades, 3 Chromascop shades, and 4 sizes. Given their high translucency, HT blocks are ideally suitable for the fabrication of smaller restorations (e.g. inlays and onlays). Restorations made of HT blocks convince users with their true-to-nature chameleon effect and outstanding adaptation to the residual tooth structure. The blocks demonstrate life-like ﬂuorescence in order to permit optimum integration into the natural residual tooth structure under different light conditions.

IPS Empress CAD LT (Low Translucency)

These blocks are available in the 9 most popular A–D shades, 3 Chromascop shades, 4 Bleach BL shades, and 4 sizes. Given their high brightness value compared to the HT blocks, the LT blocks are ideal for the fabrication of larger restorations (e.g. anterior and posterior crowns). Restorations made of LT blocks convince users with their true-to-nature brightness value and chroma, which prevents a greying of the incorporated restorations. The blocks demonstrate a life-like ﬂuorescence in order to enable optimum integration into the natural environment, even under varying light conditions. Restorations made of LT blocks are also ideally suitable for the cut-back technique.

IPS Empress CAD Multi

These blocks are available in the 5 most popular A–D shades and 3 sizes. Given the natural shade gradient from the dentin to the incisal areas, restorations made of IPS Empress CAD Multi Blocks demonstrate a maximum of aesthetics and naturalness. In conjunction with the ﬂexible positioning of the restoration within the block, the true-tonature opacity and translucency gradient enables a multitude of aesthetic possibilities. The IPS Empress CAD Multi Block features a transition of ﬂuorescence very similar to that of natural teeth, which results in excellent integration into the residual dentition. Given the innovative combination of true-to-nature transition of shade, translucency, and ﬂuorescence, highly aesthetic restorations are fabricated in an easy way.
