Dentistry - Metallic materials for fixed and removable restorations and appliances (ISO 22674:2022)

This document specifies requirements and test methods for metallic materials that are suitable for the fabrication of dental restorations and appliances. Included are metallic materials recommended for use either with or without a ceramic veneer, or recommended for both uses. Furthermore, this document specifies requirements for packaging and marking of the products and for the instructions for use of these materials, including products delivered for sale to a third party.
This document does not apply to alloys for dental amalgam (see ISO 24234), dental brazing materials (see ISO 9333), or metallic materials for orthodontic appliances (e.g. wires, brackets, bands and screws).
This document is not applicable to magnetic attachment, which are specified in ISO 13017.

Zahnheilkunde - Metallische Werkstoffe für festsitzenden und herausnehmbaren Zahnersatz und Applikationen (ISO 22674:2022)

Dieses Dokument legt die Anforderungen und Prüfverfahren für metallische Werkstoffe fest, die zur Herstellung von dentalen Restaurationen und Applikationen geeignet sind. Dieses Dokument umfasst metallische Werkstoffe, die entweder für die Verwendung mit oder ohne Keramikverblendung oder für beide Anwendungen empfohlen werden. Darüber hinaus werden in diesem Dokument Anforderungen an die Verpackung und Kennzeichnung der Produkte sowie an die Gebrauchsanweisung für diese Werkstoffe, einschließlich Produkte, die für einen Verkauf an Dritte ausgeliefert werden, festgelegt.
Dieses Dokument gilt nicht für Legierungen für dentale Amalgame (siehe ISO 24234), dentale Hartlote (siehe ISO 9333) oder für metallische Werkstoffe für kieferorthopädische Apparaturen (z. B. Drähte, Brackets, Bänder und Schrauben).
Dieses Dokument gilt nicht für magnetische Befestigungen, die in ISO 13017 festgelegt sind.

Médecine bucco-dentaire - Matériaux métalliques pour les restaurations fixes et amovibles et les appareillages (ISO 22674:2022)

Le présent document spécifie les exigences et les méthodes d’essai pour les matériaux métalliques qui sont appropriés à la fabrication de restaurations dentaires et d’appareils. Sont inclus les matériaux métalliques d’utilisation recommandée avec ou sans revêtement céramique, ou indifféremment pour ces deux utilisations. De plus, le présent document spécifie les exigences relatives au conditionnement et au marquage des produits et aux instructions d’utilisation de ces matériaux, y compris les produits commercialisés à des tiers.
Le présent document ne s’applique pas aux alliages pour amalgame dentaire (voir l’ISO 24234), aux produits pour brasage dentaire (voir l’ISO 9333), ni aux matériaux métalliques destinés aux appareils orthodontiques (par exemple fils métalliques, supports, bagues et vis).
Le présent document n’est pas applicable aux attaches magnétiques spécifiées dans l’ISO 13017.

Zobozdravstvo - Kovinski materiali za stalne in zamenljive zobne obnove in orodja (ISO 22674:2022)

Ta dokument določa zahteve in preskusne metode za kovinske materiale, ki so primerni za izdelavo zobnih obnov in orodij. Vključeni so kovinski materiali, ki se priporočajo za uporabo s keramičnimi luskami ali brez njih oziroma za obe vrsti uporabe. Ta dokument določa tudi zahteve za embalažo in označevanje izdelkov ter za navodila za uporabo teh materialov, vključno z izdelki, ki so dobavljeni za prodajo tretjim osebam. Ta dokument se ne uporablja za zlitine zobnega amalgama (glej standard ISO 24234), dentalne materiale za spajkanje (glej standard ISO 9333) ali kovinske materiale za ortodontske aparate (npr. žice, opornike, trakove in vijake). Ta dokument se ne uporablja za magnetne priključke, ki so obravnavani v standardu ISO 13017.
