28、on of masticatory function, such as dental restorative materials and dental implants are subject to standards and regulations, either in existence or in preparation, designed to evaluate the performance of these products. Implantable materials for bone filling and augmentation in oral and maxillofac
29、ial surgery are not covered by the procedures for evaluating and testing dental restorative materials and dental implants; it is necessary to develop a new standard for these materials. The aim of this International Standard is to define the content of a technical file that demonstrates safety and e
30、ffectiveness of bone filling and augmentation materials used in oral and maxillofacial surgery. 4 EN ISO 22794:2009 (E) DIN EN ISO 22794:2009-11 1 Scope This International Standard applies to implantable materials, whether resorbable or non-resorbable, used as dental devices for filling and augmenti
31、ng bones in oral and maxillofacial surgery. Products that are essentially pure ( 90 %) hydroxyapatite are not covered by this International Standard. Evaluation includes the physico-chemical, mechanical, biological and clinical aspects and behaviour of these implantable dental materials. Materials s
32、uch as autografts, allografts and membranes, and products for which the primary intended use is to deliver a medicinal product, are not covered by this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
