标准摘要
[中文适用范围]: 本文件规定了水基牙科粘固剂的要求和测试方法,其中通过酸碱反应和聚合的组合来实现凝固。 这些材料用于粘合、基底或衬里、修复和牙芯构建目的。 实施例常规的玻璃聚链烯酸酯粘固剂通常通过使可离子浸出的铝硅酸盐玻璃与聚链烯酸在水性环境中反应而形成。 落入本文献范围内的材料通常能够通过这种水性酸碱型反应进行凝固,但此外还能够通过聚合进行凝固。 注:制造商和测试实验室的注意力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最适合评估任何单个产品。 [外文原描述]: 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.
