What You Need To Know About ISO 6872:2024 For Dental Zirconia
Jul 24, 2025
In the ever-evolving world of dental restorations, safety, strength, and aesthetics are paramount. That's where ISO 6872:2024, the international standard for dental ceramic materials, plays a key role - especially for zirconia used in crowns, bridges, and implant-supported restorations.
This new version of ISO 6872 sets updated guidelines for how zirconia and other dental ceramics are tested, classified, and approved for clinical use. Let's break it down in plain terms - and see how Vsmile zirconia perfectly meets these expectations.
What is ISO 6872:2024?
ISO 6872:2024 is the latest international standard titled:
"Dentistry - Ceramic materials"
It specifies the performance requirements, testing methods, and labeling rules for dental ceramic materials, including zirconia. Its goal? To ensure that all materials used in your mouth are safe, strong, and reliable - whether it's for a single crown or a full arch restoration.
Key Performance Criteria in ISO 6872:2024
To be approved under this standard, zirconia must pass rigorous tests. Here's what matters most:
| Property | Why It Matters |
|---|---|
| Flexural Strength | Measures how much force the material can take before breaking. |
| Fracture Toughness | Indicates resistance to crack propagation. |
| Chemical Solubility | Ensures no harmful elements leach into the mouth. |
| Radiopacity | Allows dentists to see the material on X-rays. |
| Biocompatibility (ISO 10993) | Confirms the material is safe for use in the body. |
ISO 6872 also classifies zirconia into types (Type I–IV) based on strength.
High-strength zirconia (Type III or IV) is suitable for multi-unit bridges and posterior load-bearing zones.
