In most favourable cases, filigree fissures, accentuated cusp slopes and macro- textures are reproduced one to one in the ceramic. If preferred, certain macro-textures can be adjusted by grindingtogivethemadditionalem- phasis.Oncecleaned,therestoration shows a smooth shade progression from the cervical to the incisal re- gion and, as a result, the shade of the restorationlooksverynatural. At this stage, the restoration can be prepared for the glaze-firing (or optionalstain-firing)cycle.IPSe.max CeramShadesandEssencesareused for this step. The procedure is the same for both polychromatic and monochromatic restorations. For better wettability of the stains, a small quantity of Stain or Glaze Liquid is applied to the grease- and contamination-freeceramicsurface. The stains are then applied to cha- racterise the restoration according to individual requirements. The characterisations can be intensified by repeating the staining and firing procedure.Evenbeforethestainsare applied, the incisal area appears clearly more translucent than the otherpartsoftherestoration.Thisef- fectcanbeintensifiedbybrushingon a small quantity of IPS e.max Ceram ShadesIncisal.

Conclusion IPS e.max Press Multi affords a streamlined procedure that sup- ports the need for economic effi- ciency in the dental laboratory and yet does not entail sacrifices in aes- thetic quality. What is so delightful about this material is that it allows you to do all, but does not require you to do everything. With or with- out stains, the restorations exhibit a natural variation of shade and translucency from the dentine to the incisal region (Figs.12&13). High aesthetics and high efficiency are combined with the proven mate- rial properties of lithium disilicate (IPS e.max Press), such as high strength. These properties are in- corporated into the IPS e.max Press Multiingot. TRENDS&APPLICATIONS Michael Spiegel is Product Manager of All-Ceramics —CAD/CAM at Ivoclar Vivadent inSchaaninLiech- tenstein.
