Overview
ISO 9693:2026 - Dentistry - Compatibility testing for metal-ceramic and ceramic-ceramic systems is an international standard developed by the International Organization for Standardization (ISO). This standard specifies the requirements and test methods necessary to assess thermomechanical compatibility between a veneering ceramic and a metallic or ceramic substructure material, specifically for use in dental restorations such as crowns and bridges. The standard focuses on combined systems and does not allow for the conformity claim of a single component material.
ISO 9693:2026 is critical for dental professionals and manufacturers who aim to ensure the clinical performance, durability, and safety of prosthodontic materials by validating the compatibility between ceramics and substrates under conditions similar to those encountered in the oral environment.
