Standard
ISO  4049 Fifth edition 2019-05
Dentistry - Polymer-based restorative materials
Identical Adoption
ANSI ADA Standard No. 27-2022
Polymer-based Restorative Materials
Scope/Abstract
This document 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 the teeth and for luting.

The polymer-based luting materials covered by this document are intended for use in the cementation or fixation of restorations and appliances such as inlays, onlays, veneers, crowns and bridges. This document does not cover those polymer-based luting materials that have an adhesive component within the structure of the material (see ISO/TS 16506).

The document does not cover polymer-based materials intended to prevent caries (see ISO 6874), core materials or those used for veneering metal sub-frames (see ISO 10477).
Extent of Recognition
Complete standard
Rationale for Recognition
This standard is relevant to medical devices and is recognized on its scientific and technical merit and/or because it supports existing regulatory policies.
Transition Period
FDA recognition of ISO 4049 Fourth edition 2009-10 [Rec# 4-181] will be superseded by recognition of ISO 4049 Fifth edition 2019-05 [Rec# 4-298].
