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 9, Dental
CAD/CAM systems, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 55, Dentistry, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 18618:2018), which has been technically
revised.
The main change compared to the previous edition is: the XML schema for IDS (interface for dental
CAD/CAM systems) and the examples of interoperability of dental products relating to dental implant
systems, removables, dental appliances and orthodontics have been updated in Annex A due to the fast
nature of the software system innovation and the need for ongoing testing.

Introduction
Manufacturers of dental CAD/CAM systems differ in how they exchange manufacturing information and
three dimensional data. This causes difficulty in data processing, design processes and manufacturing
processes for users of those systems. In order to overcome these interoperability issues, this document
has been prepared to facilitate open interoperability between CAD/CAM systems in dentistry.

3.1 General terms
3.1.1
broker
entity that acts as a middleman or intermediary

SIST EN ISO 18618:2023
ISO 18618:2022(E)
3.1.2
interface for dental CAD/CAM systems
IDS
nodes immediately within the enveloping root element that provide traceability and source
identification features as well as information on how to reply to a document transaction
Note 1 to entry: The IDS schema organizes the IDS document into structures for specific transactions. They
represent a submission, a query, an update of a previous submission, a notification of an event or status change
and a series of catalogs. A single IDS document can contain a combination of different transaction nodes or
consist of only a single transactional node.
3.1.3
originator
entity (organization or person) that is responsible for creating the current document, order, submission
Note 1 to entry: As such, they are the “originator” of the data being exchanged.
Note 2 to entry: Most often an originator is a dental practice. In some cases, an originator is a dental laboratory
that is outsourcing work to another lab.
3.1.4
provider
entity that is responsible for providing the services or products that are being requested in an order
Note 1 to entry: An entity can be a company, a lab.
Note 2 to entry: Most often, a provider is a dental laboratory or manufacturer.
3.2 Terms related to XML content
3.2.1
brokerID
identifiers used by a broker (3.1.1) to identify itself, or by an originator (3.1.2) and a provider (3.1.3) to
identify a broker
3.2.2
CADDataCatalog
collection of nodes describing CAD data associated with one or more of either the orders or restorations,
or both
Note 1 to entry: It can include either a digital scan or design files, or both.
3.2.3
case
set of one or more orders for dental appliances, products or services, all of which are submitted for a
single patient
EXAMPLE A case can contain one order for a crown and another order for a bridge.
3.2.4
catalog
data that are referenced in other elements or areas
Note 1 to entry: The catalogs are subdivided by the data they are grouping, making it easier to manage and
reference.

ISO 18618:2022(E)
3.2.5
character data
CDATA
certain portion of the document which is general character data, rather than non-character data or
character data with a more specific, limited structure
Note 1 to entry: CDATA is used for distinct, but related, purposes in the markup languages SGML and XML.
3.2.6
DataQuery
method to request data from another system or entity
Note 1 to entry: It provides elements to define the data elements to be searched or matched on as well as elements
to define the data requested in response.
3.2.7
DeliveryRequest
information for the out-going, finished order, which is sent to the originator (or an originator’s agent) as
a separate delivery
Note 1 to entry: A delivery is either physical or electronic, or both.
3.2.8
dentist
node that defines the responsible clinician who requested the order
3.2.9
DentistCatalog
collection of dentist (3.2.8) nodes that provides attributes and elements to define the dentists being
referenced in the IDS schema
Note 1 to entry: The definition can include billing information and license information.
3.2.10
ExtraInfo
child node that can be used to extend the schema with undefined XML
Note 1 to entry: Many of the elements contain child nodes with the suffix “ExtraInfo” (i.e. ,
, etc). These are intended to be areas that can be used to extend the defined schema with
proprietary or undefined XML. For example, an implementation can use one (or more) of these to embed XML
that is only of use to the implementer for an internal workflow. Another use can be two business partners using
these to experiment with XML they intend to propose for future versions or to pass proprietary XML they have
previously defined between themselves. The IDS schema and XSD ignore the contents of these so they are not
validated as part of the IDS schema. It is highly recommended that if these are used, that any XML be enclosed
within some proprietary element tag so that if the XML document passes through multiple handlers, there are no
conflicts:

     
          data specific and of use only to “MyCompany”…
     

3.2.11
FileCatalog
collection of nodes that describe files associated with the , or CAD data
(scans, design files, etc.)

ISO 18618:2022(E)
3.2.12
host service
system that receives the IDS document and processes the contents
3.2.13
IDMapCatalog
collection of nodes which provide a means of defining alternate identifiers for key
elements within the IDS
3.2.14
notification
means for publishing or returning a defined status, event or message related to an order
Note 1 to entry: Within the notification node is an untyped element that can be defined in accordance with the
needs of the parties exchanging information.
3.2.15
order
request for a self-contained dental appliance, service or product that is being requested by an originator
Note 1 to entry: Each order in a case can be created or manufactured by a different provider. Each order contains
its own delivery (or reply) instruction nodes.
3.2.16
OrderCatalog
collection of nodes that provide attributes and elements necessary to define or describe an
order
Note 1 to entry: An will often contain one or more nodes but can omit those nodes when
not needed.
3.2.17
parcel
physical package that is mailed
3.2.18
patient
patient for whom a case is being manufactured
Note 1 to entry: Patient infomation is not a mandatory part of the IDS schema.
3.2.19
PatientCatalog
collection of nodes that provide attributes and elements to define patients that are referenced
in the or elements
Note 1 to entry: Because patients are referenced in either multiple nodes or multiple nodes, or
both, the patient information is grouped into a catalog.
3.2.20
prescription
written directive from the dentist or responsible clinician to the supplier specifying the product that
should be manufactured for the patient
3.2.21
ProductCatalog
means for a provider or broker (3.1.1) to publish the products that will be available for ordering

3.2.22
productSKU
product stocking unit used by manufacturers to identify their products to their internal systems
3.2.23
providerID
identifiers used by a broker (3.1.1) and a originator (3.1.2) to identify a provider (3.1.3), or by a provider
to identify itself
3.2.24
submission
batch or group of one or more described in the IDS document
Note 1 to entry: In traditional (non digital) dentistry, a submission is equivalent to receiving a physical
package [parcel (3.2.17)] containing one or more cases. In the digital IDS realm, the submission represents any
combination of one or more either physical or digital, or both, cases that are being “submitted” to a provider for
production.
3.2.25
UUID
universally unique identifier
label used for identifying key elements
Note 1 to entry: UUIDs are denoted in the document as string(36) to correspond to the xsd definition for the
UUIDTypeDef. 128-bit (16 bytes) number represented as a 36-character string of its hexadecimal presentation
(32 characters + separators including leading 0 values) in the format: XXXXXXXX-XXXX-XXXX-XXXX-
XXXXXXXXXXXX.
Note 2 to entry: An within the of the document provides a means of equating the UUID with
alternate identifiers that carry external meaning, such as a lab management system ids for a dentist, case or
patient.
Note 3 to entry: UUID values can have multiple alternate ids in the  but each UUID is defined only once
and used on a single key element.
EXAMPLE If the UUID “107face6-fc51-4366-805d-2ee23014d835” is assigned to the dentist “smith”, that
UUID value can possibly not be used on any other element as a key identifier and can only be used as a reference
in other elements needing to associate with that specific dentist.
3.2.26
update
means to send an abbreviated set of data elements to update or modify a previously submitted
Note 1 to entry: It contains elements that allow the update to match expected values in addition to providing the
new values.
4 Data security and storage methods
The Internet has proven to be an effective means of communication, yet its vulnerability to interception
raises issues of privacy, authentication and integrity of the communicated message. Therefore, data
security is of utmost importance to users of dental information systems.
Because of the personal and private nature of health records, the dental practitioner needs to
understand the security issues associated with “data at rest” and “data in transit.” This document is not
intended to explain security concepts and the risks associated with the maintenance of data in storage
and transit, and over an internet connection. The ADA Standards Committee on Dental Informatics has
published a series of technical reports that provide dental practitioners with guidelines in addressing
issues of security of data in storage and transmission over the internet.
A ZIP file format is recommended for transport of the IDS XML file and related files, however,
implementation of a file container is left up to the implementer.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1942, ISO 16443, ISO 18739,
W3C XML1.0, W3C XSD 1.1and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at http:// www .electropedia .org/
NOTE 1 IDS schema is defined to be the interface for dental CAD/CAM systems. Throughout the IDS schema
there are terms that have special meaning or definition. Understanding the use of these terms is the key to well-
defined IDS documents that all parties can understand universally.
NOTE 2 The IDS schema defines several peer level nodes immediately within the enveloping root
element that organizes the IDS document into structures for specific transactions. They represent a submission,
a query, an update of a previous submission, a notification of an event or status change and a series of catalogs.
A single IDS document can contain a combination of different transaction nodes or consist of only a single
transactional node.
NOTE 3 In addition to the transactional nodes mentioned above, the IDS schema also defines several nodes
that provide traceability and source identification features as well as provide information on how to reply to a
document transaction.

ISO/DIS 18618:2021(E)

3.1.1
broker
entity that acts as a middleman or intermediary
Note 1 to entry: Such organizations take multiple orders from multiple sources and consolidate them into a single
order for a Provider or they take single orders from an originator and split them among multiple providers or
they just pass orders through between originators and providers.
3.1.2
originator
entity (organization or person) that is responsible for creating the current document, order,
submission, etc.
Note 1 to entry: As such, they are the “originator” of the data being exchanged.
Note 2 to entry: Most often an originator would be a dental practice. In some cases, an originator is a dental
laboratory that is outsourcing work to another lab.
3.1.3
provider
entity (company, lab, etc.) that is responsible for providing the services or products that are being
requested in an order
Note 1 to entry: Most often, this would be a dental laboratory or manufacturer.
3.2 Terms and definitions relating to XML content
3.2.1
CADDataCatalog
collection of nodes describing CAD data associated with one or more of the orders and/or restorations
Note 1 to entry: It can include digital scan and/or design files, etc.
3.2.2
case
set of one or more orders for dental appliances, products or services, all of which are being submitted
for a single patient
EXAMPLE A case might contain one order for a crown, and another order for a bridge.
3.2.3
catalogs
data that are referenced in other elements or areas
Note 1 to entry: The catalogs are subdivided by the data they are grouping, making it easier to manage and
reference.
3.2.4
DeliveryRequest
information for the out-going, finished order, which will be sent to the originator (or an originator’s
agent) as a separate delivery
Note 1 to entry: A delivery is physical, electronic, or both.

3.2.6
DentistCatalog
collection of dentist (3.2.5) nodes that provides attribute and elements to define the dentists being
referenced within this document
Note 1 to entry: The definition can include billing information, license information, etc.
3.2.7
ExtraInfo
child node that can be used to extend the schema with undefined XML
EXAMPLE Many of the elements will contain child nodes with the suffix “ExtraInfo” (i.e. ,
, etc. These are intended to be areas that can be used to extend the defined schema with
proprietary or undefined XML. For example, an implementation may use one (or more) of these to embed XML
that is only of use to the implementer for an internal workflow. Another use could be two business partners
using these to experiment with XML they intend to propose for future versions or to pass proprietary XML they
have previously defined between themselves. The IDS schema and XSD will ignore the contents of these so they
will not be validated as part of the IDS schema. It is highly recommended that if these are used, that any XML be
enclosed within some proprietary element tag so that if the XML document passes through multiple handlers
there are no conflicts:

     
          data specific and of use only to “MyCompany”…
     

3.2.8
FileCatalog
collection of nodes that describe files associated with the , or CAD data
(scans, design files, etc.)
3.2.9
host service
system that receives the IDS document and processes the contents
3.2.10
IdMapCatalog
collection of nodes which provide a means of defining alternate identifiers for key
elements within the IDS
3.2.11
notification
means for publishing or returning a defined status, event or message related to an order
Note 1 to entry: Within the notification node is an untyped element that can be defined according to the needs of
the parties exchanging information.
3.2.12
order
request for a self-contained dental appliance, service or product that is being requested by an originator
Note 1 to entry: Each order in a case might be created or manufactured by a different provider. Each order
contains its own delivery (or reply) instruction nodes.

to define the data requested in response.
3.2.21
submission
batch or group of one or more described in the IDS document
Note 1 to entry: In traditional (non digital) dentistry a submission would be equivalent to receiving a physical
package [parcel (3.2.14)) containing one or more cases. In the digital IDS realm, the submission represents any
combination of one or more physical and/or digital cases that are being “submitted” to a provider for production.

3.2.22
UUID
universally unique identifier. It will be denoted in the document as string(36) to correspond to the
xsd definition for the UUIDTypeDef. 128-bit (16 bytes) number represented as a 36-character string
of its hexadecimal presentation (32 characters + separators including leading 0 values) in the format:
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX.
Note 1 to entry: UUIDs are a means of identifying key elements within the document.
Note 2 to entry: An  within the  of the document provides a means of equating the UUID
with alternate identifiers that carry external meaning, such as a lab management system ids for a dentist, case or
patient.
Note 3 to entry: UUID values can have multiple alternate ids in the  but each UUID is defined only once
and used on a single key element.
EXAMPLE If the UUID “107face6-fc51-4366-805d-2ee23014d835” is assigned to the dentist “smith”, that
UUID value may not be used on any other element as a key identifier and may only be used as a reference in other
elements needing to associate with that specific dentist.
3.2.23
update
means to send an abbreviated set of data elements to update or modify a previously submitted
Note 1 to entry: It contains elements that allow the update to match expected values in addition to providing the
new values.
3.2.24
providerIds
identifiers used by broker (3.1.1) and originator (3.1.2) to identify provider (3.1.3), or provider to
identify itself.
3.2.25
brokerIds
identifiers used by broker (3.1.1) to identify itself, or originator (3.1.2) and provider (3.1.3) to
identify broker.
3.2.26
character data (CDATA)
a certain portion of the document is general character data, rather than non-character data or character
data with a more specific, limited structure. CDATA is used for distinct, but related, purposes in the
markup languages SGML and XML.
4 Data security and storage methods
The Internet has proven to be an effective means of communication, yet its vulnerability to interception
raises issues of privacy, authentication and integrity of the communicated message. Therefore, data
security is of utmost importance to users of dental information systems.
Because of the personal and private nature of health records, the dental practitioner needs to
understand the security issues associated with “data at rest” and “data in transit.” This document is not
intended to explain security concepts and the risks associated with the maintenance of data in storage
and transit, and over an internet connection. The ADA Standards Committee on Dental Informatics has
published a series of technical reports that provide dental practitioners with guidelines in addressing
issues of security of data in storage and transmission over the Internet.
A ZIP file format is recommended for transport of the IDS XML file and related files, however,
implementation of a file container is left up to the implementer.
