BS EN 1641:2009EN 1641:2009 (E) 4 Introduction There are three

20、levels of European Standards dealing with medical devices used in dentistry. These are as follows: Level 1: General requirements for medical devices; Level 2: Requirements for families of medical devices used in dentistry; Level 3: Specific requirements for types of medical devices used in dentistry

21、. There are no level 1 standards written exclusively in respect of medical devices used in dentistry. This European Standard is a level 2 standard and details requirements that apply to those materials used in the practice of dentistry for the restoration of the form and function of the dentition (f

22、or dental implants see EN 1642) and those for the practice of orthodontics. It is also indicated that there are additional requirements in the level 3 standards. Where available, these are included as normative references. To cover all the requirements for a particular product, it is necessary to us

23、e a standard of the lowest available level. The manufacturer will need to consider whether: 1) The material incorporates, as an integral part, a substance which, if used separately, may be considered to be a medicinal product as defined in Article 1 of Directive 2001/83/EEC 2, and whose action in co

24、mbination with the material can result in its bioavailability. Directive 2001/83/EEC specifies the appropriate methods for assessing the safety, quality and usefulness of that substance. 2) The material includes a constituent which may be classified as a hazardous substance according to the Dangerou

25、s Substances Directive 67/548/EEC 3, as amended by the Dangerous Preparations Directive 1999/45/EC 4. Attention is drawn to the labelling requirements of these Directives where the hazardous constituent content is above certain concentration limits. A reference for guidance on the classification of

26、dental devices and accessories is given in the Bibliography 6. BS EN 1641:2009EN 1641:2009 (E) 5 1 Scope This European Standard specifies general requirements for materials used in the practice of dentistry for the restoration of the form and function of the dentition and which are medical devices.

27、For the purposes of this standard these materials are defined as restorative and orthodontic materials. Dental implants are specifically excluded and described in EN 1642. This standard also specifies general requirements for materials used in the practice of orthodontics. This standard includes req

28、uirements for intended performance, design attributes, components, sterilization, packaging, marking, labelling, and information supplied by the manufacturer. Tests for demonstrating compliance with this standard are contained in the level 3 standards, if appropriate. 2 Normative references The foll
