ISO 10477-2020 pdf free.Dentistry — Polymer-based crown andveneering materials.
1.This document classifies polymer-based crown and veneering materials used in dentistry and specifiestheir requirements. It also specifies the test methods to be used to determine conformity to theserequirements.
This document is applicable to polymer-based crown and veneering materials for laboratory-fabricatedpermanent veneers or crowns. It also applies to polymer-based dental crown and veneering materialsfor which the manufacturer claims adhesion to the substructure without macro-mechanical retentionsuch as beads or wires.

3.1.polymer-based crown and veneering material:composition of powders and liquids or pastes that may contain monomers, inorganic and/or polymericfillers and that, when polymerized, is suitable for use as permanent dental veneers or crowns.
3.2.dentine resin:pigmented and slightly translucent polymer-based crown and veneering material (3.1) that simulates thenatural appearance of dentine.
3.3.enamel resin:translucent and slightly pigmented polymer-based crown and veneering material (3.1) that is packed in alayer over the dentine resin and that simulates the natural appearance of enamel.
3.4.cervical resin:intensely pigmented and slightly translucent polymer-based crown and veneering material (3.1) thatsimulates the natural appearance of dentine of the cervical region of the tooth.
The polymer-based crown and veneering materials described in this document shall be classifiedaccording to their activation system for polymerization.
Type 1: polymer-based crown and veneering materials whose setting is effected by mixinginitiator(s) and activator(s) (“self-curing” materials);
Type 2: polymer-based crown and veneering materials whose setting is effected by the applicationof energy from an external source (“external-energy-activated”materials), such as heat and/orradiation (visible or UV range).ISO 10477 pdf download.
