Dentistry - Polymer-based crown and veneering materials (ISO 10477:2020)
This document classifies polymer-based crown and veneering materials used in dentistry and specifies their requirements. It also specifies the test methods to be used to determine conformity to these requirements. This document is applicable to polymer-based crown and veneering materials for laboratory-fabricated permanent veneers or crowns. It also applies to polymer-based dental crown and veneering materials for which the manufacturer claims adhesion to the substructure without macro-mechanical retention such as beads or wires.
EN ISO 10477:2020 (ISO 10477:2020) is a CEN-adopted international standard for polymer-based crown and veneering materials used in dentistry. It classifies polymer dental restorative materials for laboratory-fabricated permanent crowns and veneers and specifies the requirements and test methods manufacturers and test laboratories must use to demonstrate conformity. The standard also covers polymer-based materials that rely on chemical adhesion to a substructure without macro-mechanical retention (for example, without beads or wires).
The standard defines both material classification and detailed performance requirements. Major technical topics include:
The document provides step-by-step measurement and test methods (apparatus, specimen preparation, procedures and result expression) for each requirement.
EN ISO 10477:2020 is essential for:
