BS EN 1642:2011EN 1642:2011 (E) 4 Introduction There are three lev

20、els 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. T

21、here 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 dental implants (for surgically implantable dental materials included within the definition of restorative materials

22、see EN 1641). 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 use a standard of the lowest available level. In the bibliograph

23、y a reference for guidance on the classification of dental devices and accessories 4 is given. BS EN 1642:2011EN 1642:2011 (E) 5 1 Scope This European Standard specifies general requirements for dental implants and accessories. Surgically implantable dental materials defined as restorative materials

24、 are specifically excluded and described in EN 1641. This European Standard includes requirements for intended performance, design attributes, components, sterilization, packaging, marking, labelling, and information supplied by the manufacturer. 2 Normative references The following referenced docum
