IPS Empress CAD restorations are ideally suited to restore small defects with an all-ceramic material, as well as to replace
less esthetic restorations. Given the true-to-nature chameleon effect, IPS Empress CAD restorations beautifully blend in
with the residual tooth structure. In this processing technique, the restoration is polished and incorporated immediately
after milling in the CAD/CAM system. In the process, the surface lustre is achieved by manual polishing. Therefore, this
processing method is very efficient and leads to esthetic results in a quick and easy fashion.
For information on the CAD/CAM processing, please refer to the respective Instructions for Use and the
manuals of the respective CAD/CAM system. The instructions of the manufacturer must be observed.
The available product range may vary from country to country and may depend on the CAD/CAM system used.

The attachment point of the holder is smoothed out, while the proximal contact points are taken into account.
Proximal areas and larger surfaces are polished extra-orally.
Finishing
For finishing and adjusting glass-ceramics, appropriate grinding instruments are indispensable. If the wrong grinding instru-
ments are used, marginal chipping and local overheating may occur.
The following procedure is recommended for finishing IPS Empress CAD restorations:
– Use only suitable, fine-grained (grain size < 60 µm), ceramic-bonded grinding instruments or diamonds at a speed of up
to 20,000 rpm and little pressure.
– Carefully finish the restoration margins using rubber and silicone polishers (speed: < 10,000 rpm).
– Avoid overheating of the glass-ceramic.
– Smooth out the attachment point of the holder and take the proximal contact points into account.
– Carry out individual shape adjustments, if required.
– Try in the restoration and adjust the occlusion / articulation, if necessary.
– Polish proximal areas and large surfaces extra-orally prior to cementation.
