Dentistry - Colour tabs for intraoral tooth colour determination (ISO 22598:2020)

This International Standard describes requirements for tooth-like colour representations made of
ceramic materials used to determine the tooth colour in the patient’s mouth or to check the colour of
dental prosthesis, which are referred to as shade guides (colour rings) in this standard.
The coordinates of tooth colours in the colour space (colour coordinates) the specification of which is left
to the manufacturers’ discretion as well as the colour deviations of ceramic and other masses or materials
used in the manufacture of dental prosthesis do not fall into the scope of this standard.
Resources for visualizing the colours of ceramic and other masses, e.g. mass shade guides and colour
patterns for certain ceramic and other masses, do not fall into the scope of this International Standard.
They can be manufactured from any materials and serve solely to illustrate the colour effect; they do not
serve colour determination inside the mouth.

Zahnheilkunde - Farbschlüssel für die intraorale Zahnfarbbestimmung (ISO 22598:2020)

Dieses Dokument legt Anforderungen an zahnähnliche Farbverkörperungen aus keramischen Massen fest, die zur Bestimmung der Zahnfarbe im Patientenmund oder zur Überprüfung der Farbe von Zahnersatz verwendet werden und die in diesem Dokument als Farbschlüsselzähne bezeichnet werden.
Die Farbkoordinaten von Farbschlüsselzähnen können von den Herstellern beliebig festgelegt werden.
Hilfsmittel zur Visualisierung der Farben von keramischen und sonstigen Massen, z. B. Massenfarbschlüssel und Farbmuster für bestimmte keramische und sonstige Massen gehören nicht zum Anwendungsbereich dieses Dokumentes. Diese können aus beliebigen Materialien hergestellt werden und dienen lediglich der Veranschaulichung der Farbwirkung; sie dienen nicht zur Farbbestimmung im Mund.

Médecine bucco-dentaire - Plaquettes de teinte pour la determination de la teinte dentaire intra-buccale (ISO 22598:2020)

Le présent document spécifie les exigences applicables aux nuanciers dentaires fabriqués en céramique et utilisés pour déterminer la teinte des dents dans la bouche d'un patient ou pour contrôler la teinte de la prothèse dentaire, appelées plaquettes de teinte dans le présent document.
Le choix des coordonnées chromatiques des plaquettes de teinte est laissé à la discrétion du fabricant.
Les ressources permettant de visualiser les teintes de la céramique et d'autres masses, par exemple les teintiers de masses et les coloris pour certaines céramiques et d'autres masses, ne font pas partie du domaine d'application du présent document. Ils peuvent être fabriqués à l'aide de n'importe quel matériau et servent uniquement à illustrer l'effet chromatique; ils n'ont pas pour objectif de déterminer la teinte intra-buccale.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
