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 13017 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2, Prosthodontic
materials.

Introduction
The early practical uses of permanent magnets were as navigational compasses. Magnets have since become
firmly integrated into today’s modern electronic device technology. The development of magnetic technology
has generated rare earth magnets. Their excellent magnetic character properties permit predictable clinical
applications and use. Dental magnetic attachments are one of the products composed of rare earth magnets,
providing retention, support and stabilization of dental and maxillofacial appliances.

INTERNATIONAL STANDARD ISO 13017:2012(E)
Dentistry — Magnetic attachments
1 Scope
This International Standard specifies requirements and test methods for assessing the applicability of dental
magnetic attachments that provide retention, support and stabilization of crowns and bridges, removable
partial dentures, overdentures, superstructures of dental implants and orthodontic or maxillofacial prostheses
including obturators.
This International Standard does not specify qualitative and quantitative test methods for demonstrating
freedom from unacceptable biological risk, which can be assessed using ISO 10993-1 and ISO 7405.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1942 and the following apply.
3.1
magnetic attachment
device to provide retention of a prosthesis utilizing magnetic attraction as shown in Figures 1 and 2
3.1.1
open magnetic circuit attachment
magnetic attachment which utilizes an open magnetic circuit between coupled components
NOTE The magnet is encased within a corrosion-resistant metal or alloy cover of titanium, titanium alloy or stainless
steel to prevent corrosion of the magnet, and utilizes the attractive force between either two magnets or between a magnet
and a ferromagnetic alloy keeper as retentive coupling components.
See Figure 1.

3.2
magnetic assembly
assembly composed of a small magnet which is sealed within ferromagnetic yokes and non-magnetic spacers,
completing closed magnetic circuits
NOTE The closed magnetic circuit is a complete circulating path for magnetic flux through the yoke and keeper, which
are made of ferromagnetic materials. This circuit can enhance the retentive force and reduce the magnetic flux leakage.
