BS EN ISO 9917-2:2010

Dentistry. Water-based cements. Resin-modified cements | Status: Superseded, Withdrawn

1 Scope This part of ISO 9917 specifies requirements and test methods for dental cements that are intended for luting, base or lining and restoration purposes and for which the materials are water-based and set by multiple reactions in which setting is achieved by a combination of an acid-base reaction and polymerization.

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 part of ISO 9917 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 Attention of manufacturers and test laboratories is drawn to the closely-related International Standards ISO 4049 and ISO 9917-1. Consideration should be given as to which is the most appropriate International Standard by which to evaluate any individual product.
