Shade Determination
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.
SR Adoro – Individualized shade determination
it goes without saying that the materials shade guides are an inte-
gral part of the sR Adoro product concept. the dentin shade tabs
feature a textured surface and anatomical shape for light refraction
purposes. the other shade tabs are slightly wedge-shaped to take
account of the translucency of the individual materials. All shade
tabs feature a smooth, i.e. untextured, reverse side to assist users in
comparing the shades against the prepared tooth and coloured
cements and adhesives. the smooth side of the shade tabs may be
individually ground to determine the layering. the individual shade
tabs are made of ceramic for reasons of shade stability. they are
fired of specially coloured ceramic materials to ensure that they
comply with the individual sR Adoro materials. As the materials
shade guides have been modelled on the ips d.siGN and ips inLine
system shade guides, the sample holders of the sR Adoro shade
guides are coloured light grey to distinguish them from the shade
guides of other materials.
