11、nt supersedes CEN/TR 12401:2003. 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. PD CEN/TR 12401:2009 CEN/TR 12401:2009 (E) 4 Introduction Dental products are marketed for long

12、 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 implant

13、ed 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.

14、 Many dental materials, instruments, equipment and disposables are covered by the Council Directive 93/42 EEC of 14 June 1993 concerning medical devices. The Directive also provides rules for the classification of medical devices based on risk and intended use. It is the manufacturers responsibility

15、 to classify the product according to the rules of the Directive. The classification should be acceptable to Notified Bodies (NB) and Competent Authorities (CA). The Directive describes procedures for resolving any disputes over classification between manufacturers, Notified Bodies and Competent Aut

16、horities. The European Commission has developed a document ”Guidelines for the Classification of Medical Devices”. This CEN Technical Report is intended to complement that guidance. In addition, NB-MED, European Co-ordination of Notified Bodies, have developed a series of consensus statements which

17、also have been taken into consideration. It will, therefore, be of value to manufacturers in making decisions with regard to the likely classification of particular devices. PD CEN/TR 12401:2009 CEN/TR 12401:2009 (E) 5 1 Scope This CEN Technical Report provides guidance on the application of the cla

18、ssification rules in Council Directive 93/42 EEC of 14 June 1993, amended by Directive 2007/47/EC, concerning medical devices as they pertain to dental devices and accessories. 2 Classification of dental devices and accessories The list of dental devices and accessories given in Tables 1 to 5 should

19、 not necessarily be considered 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 prefab

20、ricated 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 classificati

21、on. In this document the implementing rule 2.5 of the Directive has been used for the proposed classification, i.e. ”the strictest rules.shall apply”. It is recommended that this list be considered in conjunction with the Directive 93/42 EEC 1 and the ”Guidelines to the classification of medical dev

22、ices” (MEDDEV 2.4.1, latest revision) 2, as prepared by the Commission (see Bibliography). 3 Proposals for classification of dental devices and accessories Proposals for classification of dental devices and accessories are given in Tables 1 to 5.
