Practical procedure for restoration with IPS e.max | Die – Shade determination
Die – Shade determination
The IPS Natural Die Material Shade Guide is used to determine the die shade.
Determining the die shade at the end of the preparation is a very important step for the fabrica-
tion of all-ceramic restorations. Especially with severely discoloured preparations this is of ut-
most importance. Only if the dentist determines the shade of the preparation and considers it
in the selection of the restorative material, may the desired esthetics be achieved in a targeted
fashion.
Shade determination on the prepared tooth/die
– Carry out the shade determination at daylight.
– Carry out the shade determination on the prepared tooth.

Temporary restoration
Function, phonetics and esthetics of the permanent restoration are predefined
and may still be adapted any time. For this essential treatment step, the Telio
®
product system provides a multitude of application options.
Important: The temporary restoration is cemented with a temporary, eugenol-free cement, such
as the dual-curing Telio ® CS Link.
