Full title and description

ISO 4049:2019 — Dentistry — Polymer-based restorative materials. This International Standard specifies classification, performance requirements and test methods for polymer-based restorative and luting materials supplied for mechanical mixing, hand-mixing or external/intra-oral energy activation, intended primarily for direct or indirect restorations and for luting of restorations and appliances.

Abstract

ISO 4049:2019 sets out requirements and standardized tests (sampling, specimen preparation and measurement procedures) for polymer-based dental restorative materials and polymer-based luting materials. It defines types and classes of materials, minimum values and limits for key properties (e.g., flexural strength, working and setting time, water sorption and solubility, depth of cure for certain materials, film thickness for luting materials, radio-opacity) and lists exclusions and related standards for specific material categories. The standard was issued as the fifth edition in 2019.

General information

• Publication date: May 2019 (Edition 5, 2019-05).
• Publisher: International Organization for Standardization (ISO), prepared by ISO/TC 106/SC 1 (Dentistry — Filling and restorative materials).
• ICS / categories: 11.060.10 (Dental materials).
• Edition / version: 5th edition (ISO 4049:2019).
• Number of pages: 29 (as published by ISO; national/adopted versions may show differing page counts due to national forewords and formatting).

Scope

Applies to polymer-based restorative materials and polymer-based luting materials intended for restoration and cementation of dental restorations and appliances. Excludes polymer-based materials intended to prevent caries, core build-up materials and materials used for veneering metal sub-frames; it also excludes polymer-based luting materials that incorporate an adhesive component within the material structure (for which ISO/TS 16506 is relevant). The standard covers both direct restorative materials and those fabricated extra-orally and subsequently luted.

Key topics and requirements

• Classification by Type and Class (Type 1: suitable for occlusal restorations; Type 2: other restoratives and luting) and by curing mechanism (Class 1 self‑curing; Class 2 externally activated; Class 3 dual‑cure).
• Mandatory performance tests and limits: flexural strength (minimum values specified by type/class), water sorption and solubility limits, working and setting time, depth of cure requirements for certain light‑activated materials, film thickness for luting materials, and radio‑opacity tests (reference to ISO 13116).
• Biocompatibility guidance: references to ISO 10993-1 and ISO 7405 for biological/toxicological assessment (standard itself does not replace biological testing requirements).
• Specification of sampling, specimen preparation and conditioning procedures to ensure reproducible laboratory testing and reporting.
• Manufacturing and information requirements: the 2019 edition requires manufacturers to publish details of material composition (clause updates compared with prior edition).

Typical use and users

Used by dental material manufacturers (for product development, quality control and labelling), independent testing laboratories, conformity assessment bodies, regulatory authorities, dental researchers and standards committees. Dental clinicians and procurement specialists consult the standard indirectly through product specifications and declarations of conformity.

Related standards

Standards commonly referenced alongside ISO 4049 include ISO/TS 16506 (polymer‑based luting materials with adhesive components), ISO 6874 (materials intended to prevent caries), ISO 10477 (core and veneering materials for metal sub‑frames), ISO 10993‑1 and ISO 7405 (biocompatibility/toxicology guidance), and ISO 13116 (radio‑opacity test reference). National adoptions (EN/ISO, BS EN ISO, DIN EN ISO, etc.) exist and may include national forewords or national annexes.

FAQ

Q: What is this standard?

A: ISO 4049:2019 is the International Standard that specifies classification, requirements and test methods for polymer‑based dental restorative and luting materials.

Q: What does it cover?

A: It covers polymer‑based materials supplied for mechanical, hand or energy‑activated curing used for direct and indirect restorations and for luting; it gives test methods and minimum/maximum limits for key physical and chemical properties and requirements for information and sampling. It excludes certain adhesive luting materials, caries‑preventive polymers, core build‑up materials and veneering materials for metal sub‑frames.

Q: Who typically uses it?

A: Manufacturers, testing laboratories, regulatory bodies, conformity assessors, dental researchers and, indirectly, clinicians and purchasers who rely on manufacturers’ declarations and test reports.

Q: Is it current or superseded?

A: ISO 4049:2019 is the current (5th) edition published in May 2019. The ISO bibliographic record shows the publication was reviewed and confirmed in 2024, so this edition remains current. It replaced ISO 4049:2009.

Q: Is it part of a series?

A: ISO 4049 is a standalone standard for polymer‑based restorative/luting materials but is closely related to and cross‑referenced with other dental material standards (ISO/TS 16506, ISO 6874, ISO 10477, ISO 10993‑1, ISO 7405, ISO 13116, etc.). Nationally adopted versions (EN ISO, BS EN ISO, DIN EN ISO, etc.) exist.

Q: What are the key keywords?

A: dental restorative, polymer-based, luting, composite, flexural strength, water sorption, solubility, depth of cure, radio-opacity, ISO 4049.
