Finishing
For finishing glass-ceramics, appropriate grinding instruments are indispensable. If the wrong grinding instruments are
used, marginal chipping and local overheating my 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.
– Overheating the glass-ceramic must be prevented.
– Smooth out attachment point of the holder and take the proximal contact points into account.
– Carry out individual shape adjustments, if required.
– Try in and adjust occlusion/articulation, if necessary.
– Extra-oral polishing of proximal areas and large surfaces prior to cementation.
