Improving reliability and efficiency in dental materials testing

At NIOM, we recognize that accurate and precise test results rely on a solid foundation. That’s why we are continuously innovating and investing in state-of-the-art specimen preparation equipment.

In accredited testing of dental ceramics, such as biaxial flexural strength in accordance with ISO 6872, many test specimens is often required. To meet this demand with both efficiency and consistency, NIOM has invested in equipment that automates the surface preparation process. Compared to manual grinding and polishing, this significantly improves reproducibility and reduces preparation time—leading to more accurate and precise test outcomes.

However, automated processing typically requires standardized specimen shapes. For biaxial flexural strength testing, the specimens are thin disks that cannot be resin-mounted in the traditional way. To address this challenge, our in-house workshop has developed custom brass specimen holders, enabling proper preparation of these samples.

By investing in modern equipment and creating innovative solutions, NIOM continues to strengthen their ability to ensure that dental biomaterials are safe and effective for the Nordic population.
