European foreword
This document (FprCEN/TR 12401:2022) has been prepared by Technical Committee CEN/TC 055
“Dentistry”, the secretariat of which is held by DIN.
This document is currently submitted to the Vote on TR.
The responsible working group is CEN/TC 55/WG 3 "Classification" (secretariat: DIN), representing the
dental trade and industry, the dental profession and notified bodies.

Introduction
Dental products are marketed for long term, short term and transient use in the mouth. A large number
of items have been developed to assist in the treatment and prevention of oral diseases and the handling
of dental materials. In contrast to pharmaceuticals (medicinal products), many dental materials are
intended to perform as implanted devices in the oral cavity with a minimum of degradation and release
of substances, i.e. their main action is to replace lost and defective teeth and oral tissue. Some materials
contain elements that may initiate toxic or allergic responses. Other materials have additions of medicinal
substances.
Many dental materials, instruments, equipment and disposables are covered by the Regulation (EU)
2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices. The
Regulation also provides rules for the classification of medical devices based on risk and intended use. It
is the manufacturer’s responsibility to classify the product according to the rules of the Regulation.
It is important that the classification is acceptable to Notified Bodies (NB) and Competent Authorities
(CA). The Regulation describes procedures for resolving any disputes over classification between
manufacturers, Notified Bodies and Competent Authorities.
The Medical Device Coordination Group (MDCG) has prepared a document, MDCG 2021-24 "Guidance on
classification of medical devices". This document is intended to complement that guidance. It will,
therefore, be of value to manufacturers in making decisions with regard to the likely classification of
particular devices.

1 Scope
This document provides guidance on the application of the classification rules in Regulation (EU)
2017/745 of the European Parliament and of the Council of 5 April 2017 concerning medical devices as
they pertain to dental devices and accessories.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
EN ISO 1942, Dentistry — Vocabulary (ISO 1942)
3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 1942 apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
4 Classification of dental devices and accessories
The list of dental devices and accessories given in Tables 1 to 5 is not exhaustive. The classification is
based on the most commonly accepted form and intended use of the devices and accessories listed. If a
manufacturer proposes another intended use, the classification of the product may need to be
reconsidered.
Materials and other prefabricated devices that will be part of a custom made device are included in this
guidance document. Custom made devices are not. Some materials can be used both for long term and
short term custom made devices. The intended purpose claimed by the manufacturer will then be
decisive for the classification. In this document, the implementing rule 3.5 of the Regulation has been
used for the proposed classification, i.e. ”the strictest rules.shall apply”.
This list is intended to be considered in conjunction with the Regulation 2017/745 EU [1] and MDCG
2021-24 "Guidance on classification of medical devices" [2] as prepared by the Medical Device
Coordination Group (MDCG).
Classifications of dental devices and accessories are given in Tables 1 to 5.
