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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 16744 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2, Prosthodontic
materials.
This corrected version of ISO 16744:2003 incorporates the following corrections.

Introduction
Dental base metal materials are suitable for use in fabrication of fixed dental restorations.
Specific qualitative and quantitative requirements for freedom from biological hazard are not included in this
International Standard but it is recommended that, in assessing possible biological hazards, reference be made
to ISO 10993-1 and ISO 7405.
For base metal materials that are also intended as the substructure of a metal-ceramic dental restorative
system, ISO 9693 also applies.

4 Classification
For the purposes of this International Standard, dental base metal materials are classified, according to their
mechanical properties and the application for which they are recommended, as follows:
Type 1: Low strength: for applications subject to very slight stress, e.g. inlays.
Type 2: Medium strength: for applications subject to moderate stress, e.g. inlays, onlays and full crowns.
Type 3: High strength: for applications subject to high stress, e.g. onlays and overlays, crowns, thin cast
backings, pontics, and implant-retained suprastructures.
Type 4: Extra high strength: for applications subject to very high stress, e.g. veneered single crowns, long-
span bridges or bridges with small cross-sections, bars
