Table on Block Selection
IP
S
The blocks are selected on the basis of the desired tooth shade (Bleach BL or A-D), the determined die shade (ND 1 - ND 9),
and/or abutment shade, as well as the desired processing technique. The following procedure results in the selection of the
appropriate block:
1. Select the column with the desired tooth shade.
2. Select the line with the shade of the preparation.
3. Select the adequate block in accordance with the desired processing technique (staining, cut-back, or layering tech-
nique) in the intersection field.
4. If a certain combination is not possible (e.g. HT block on a dark preparation), select a block with a lower translucency.

– The recommendations for the block selection correlate with the indications as well as the preparation guide-
lines and minimum layer thicknesses.
– In case of shade deviations, adjust the restoration shade by means of characterization with Shades and/or
Stains or Essence.
– If (highly) translucent blocks are used, the layer thickness and die shade must be carefully observed.
– With thicker layers, a block with lower translucency must be selected to prevent a loss in brightness
(graying).
