Shade determination of the natural tooth

After tooth cleaning, the tooth shade of the non-prepared tooth and/or the adjacent teeth is

determined with the help of a shade guide. Individual characteristics have to be considered when

determining the tooth shade. If a crown preparation is planned, for example, the cervical shade should

also be determined. In order to achieve the best possible true-to-nature results, shade determination

should be carried out at daylight. Furthermore, the patient should not wear clothes of intensive colours

and/or lipstick.

Die shade selection

In order to facilitate the reproduction of the desired tooth shade, the shade of the preparation is

determined with the help of the IPS Natural Die Material shade guide. This enables the technician to

fabricate a model die similar to the preparation of the patient, on the basis of

which the correct shade and brightness values of the all-ceramic restorations

may be selected.

IPS e.max Ceram Material Shade Guides

For IPS e.max Ceram, the material shade guides are an integral part of

the product concept. For reasons of light refraction, the dentin shade

tabs have been given an anatomical shape and surface structure. All

the other shade tabs demonstrate a slight wedge shape, in order to

better illustrate the translucency of the individual materials. The shade

tabs are ﬁred from the original ceramic materials. To facilitate the

distinction from the existing material shade guides (e.g. IPS d.SIGN,

IPS InLine, SR Adoro), the rods and holders of the IPS e.max Ceram

material shade guides are light-grey.
