1 Scope
This standard specifies requirements for dental polymer-based restorative materials supplied in a form suitable for mechanical mixing, hand-mixing, or intra-oral and extra-oral external energy activation, and intended for use primarily for the direct or indirect restoration of cavities in the teeth and for luting.
The polymer-based luting materials covered by this standard are intended for use in the cementation or fixation of restorations and appliances such as inlays, onlays, veneers, crowns and bridges. This standard does not cover those polymer-based luting materials that have an adhesive component within the structure of the material.
This International Standard does not cover materials intended to prevent caries (see YY 0622-2008) or those used for veneering metal sub-frames (see YY 0710).
