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
Based on the IPS natural die shade guide, a die for a framework-
free restoration is fabriacated. this die is used as control die in
conjunction with the restoration to check the shade.
