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. 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. www.iso.org/patents

Introduction
Terms and designations for individual system parts and process steps used in product descriptions and
instructions for use provided by the manufacturers of dental CAD/CAD systems differ from each other,
thus creating confusion among dentists and dental technicians. In order to overcome these ambiguities,
it was decided to prepare an International Standard for terminology used in the process chain for
CAD/CAM systems.
For the purposes of illustrating the logic sequence of the process chain for CAD/CAM systems, a flow
chart of this process chain is shown in Annex A.
INTERNATIONAL STANDARD ISO 18739:2016(E)
