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.

The International Organization for Standardization (ISO) draws attention to the fact that it is claimed

that compliance with this document may involve the use of a patent.

ISO takes no position concerning the evidence, validity and scope of this patent right.

The holder of this patent right has assured ISO that he/she is willing to negotiate licences under

reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this

respect, the statement of the holder of this patent right is registered with ISO.

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:

NOTE 1 Throughout the IDS (interface for dental CAD/CAM systems) 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.

---------------------- Page: 13 ----------------------
SIST EN ISO 18618:2018
ISO 18618:2018(E)
3.1.1
broker
entity that acts as a middleman or intermediary

Note 1 to entry: Such organizations may take multiple orders from multiple sources and consolidate them into

a single order for a Provider or they may take single orders from an originator and split them among multiple

providers or they may 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 may be 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 may be physical, electronic, or both.
3.2.5
dentist
dentist or responsible clinician who requested the order

ISO 18618:2018(E)
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 sections 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 sections to

embed XML that is only of use to the implementer for an internal workflow. Another use could be two business

partners using these sections 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 sections so they will not be validated as part of the IDS schema. It is highly recommended that

if these sections 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.

3.2.15
patient
patient for whom a case is being manufactured
Note 1 to entry: Patient info is not a mandatory part of the IDS schema.
3.2.16
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 may be referenced in multiple nodes and/or multiple nodes the

patient information is grouped into a catalog.
3.2.17
prescription

written directive from the dentist or responsible clinician to the supplier specifying the product that

should be manufactured for the patient
3.2.18

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 may represent any

combination of one or more physical and/or digital cases that are being “submitted” to a provider for production.

ISO 18618:2018(E)
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 section within the section 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 section but each UUID shall be

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.
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 (American Dental Association) 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.
5 Naming

The file name shall end with an .ids extension. The file name can be prepended with any naming

convention that the user desires.
6 Tooth numbering system

Throughout the entire document, the tooth number system shall be based on ISO 3950 for tooth

numbering.
7 Measurement units
All units are in millimetres unless otherwise specified.
