标准范围

ISO 9917-2:2017规定了通过酸碱反应和聚合作用实现凝固的水基牙科粘合剂的要求和试验方法。这些材料用于粘接、基底或衬里、修复和牙核构建。示例:常规玻璃聚烷酸酯水泥通常是通过在水环境中使可离子浸出的铝硅酸盐玻璃与聚烷酸反应形成的。本文件范围内的材料通常能够通过此类水性酸碱反应实现凝固，但此外，还可以通过聚合进行凝固。注意，制造商和测试实验室的关注被吸引到密切相关的国际标准ISO 4049和ISO 9917？1，以便他们可以考虑哪一个是最合适的评估任何单个产品。

ISO 9917-2:2017 specifies requirements and test methods for water-based dental cements in which setting is achieved by a combination of an acid-base reaction and polymerization. The materials are intended for luting, base or lining, restoration and tooth core build up purposes.EXAMPLE Conventional glass polyalkenoate cements are normally formed by reacting an ion-leachable aluminosilicate glass with a polyalkenoic acid in an aqueous environment. Materials that fall within the scope of this document will normally be able to effect setting by such an aqueous acid-base type reaction but in addition will be able to undergo setting by polymerization.NOTE The attention of manufacturers and test laboratories is drawn to the closely-related International Standards ISO 4049 and ISO 9917？1 so that they can consider which is the most appropriate for evaluating any individual product.
