Dentistry - Compatibility testing for metal-ceramic and ceramic-ceramic systems (ISO 9693:2019)

This standard specifies requirements and test methods to assess the thermomechanical compatibility between a veneering ceramic and a metallic or ceramic substructure material used for dental restorations. This document applies only to the materials used in combination. Conformity cannot be claimed for a single material. For requirements for ceramic materials, see ISO 6872. For requirements for metallic materials see ISO 22674.

Zahnheilkunde - Kompatibilitätsprüfungen für metall-keramische und keramisch-keramische Systeme (ISO 9693:2019)

In diesem Dokument werden Anforderungen und Prüfverfahren zur Beurteilung der Kompatibilität zwischen einer Verblendkeramik und einem metallischen oder keramischen Gerüstwerkstoff, die zur Herstellung von dentalen Restaurationen verwendet werden, festgelegt.
Dieses Dokument gilt nur für Werkstoffe, die in Kombination verwendet werden. Die Erfüllung der Anforderungen kann nicht für einen Werkstoff allein beansprucht werden.
Für Anforderungen an keramische Werkstoffe siehe ISO 6872. Für Anforderungen an metallische Werkstoffe siehe ISO 22674.

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

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

.org/iso/foreword .html.

This document was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2,

Prosthodontic materials.

This third edition cancels and replaces ISO 9693-1:2012 and ISO 9693-2:2016, which have been

technically revised.
The main changes compared to the previous editions are as follows:

— this document focuses only on the compatibility of veneering ceramics fired on to metallic or ceramic

substrate materials. Tests of dental veneering ceramics themselves, whether for either metal or

ceramic substructures, are now contained in ceramics standard ISO 6872;

— some clauses are relevant for all materials (e.g. measurement of thermal expansion coefficients);

— the de-bonding test (formerly denoted the Schwickerath bond characterization test) for veneering

ceramic fired to a substrate is retained for metallic substrates and for ceramic substrates with an

elastic modulus less than 250 GPa;

— a new requirement has been added for metal-ceramic systems to undergo thermal shock testing

according to either of two protocols.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/members .html.

Introduction

Dental veneering ceramics and metal alloys or substructure ceramics are suitable materials for the

fabrication of dental restorations. Compatibility between the veneering ceramic and the substructure

material under mechanical and thermal loading is essential if they are to function in a prosthetic

construction.

This document specifies requirements and test methods for assessing the risk of failure associated with

masticatory forces and the oral environment.
