Overview - EN ISO 22112:2017 (Dentistry - Artificial teeth for dental prostheses)
EN ISO 22112:2017 / ISO 22112:2017 specifies the classification, requirements and test methods for industrially manufactured artificial teeth used in dental prostheses. The standard covers both ceramic teeth and polymer teeth, addressing properties that affect safety, fit and long‑term performance of removable and fixed dental prostheses. EN ISO 22112:2017 supersedes EN ISO 22112:2006 and was adopted by CEN members in 2017.
Keywords: EN ISO 22112:2017, ISO 22112:2017, artificial teeth, dental prostheses, ceramic teeth, polymer teeth, dental materials
Key topics and technical requirements
The standard organizes requirements and test methods across essential quality areas, including:
- Classification of artificial teeth by material type and intended use.
- General requirements: biocompatibility, dimensional specifications, shade matching and surface finish.
- Ceramic teeth: radioactivity screening, anchorage to denture bases, resistance to thermal shock.
- Polymer teeth: bonding to denture‑base polymers, resistance to blanching/distortion/crazing, colour stability and dimensional stability.
- Defect control: porosity and other manufacturing defects for both ceramic and polymer teeth.
- Sampling, measurement and test methods: visual inspection, dimensional measurement, shade comparison, surface finish evaluation, porosity testing, radioactivity measurement, and mechanical/thermal test procedures.
The published table of contents lists detailed test procedures (sample prep, apparatus, conditioning and assessment) for each requirement area.
Practical applications
EN ISO 22112:2017 provides a standardized framework to ensure artificial teeth meet consistent safety and quality benchmarks. Typical applications:
- Product specification and quality control for manufacturers of ceramic and polymer artificial teeth.
- Development and validation of bonding and processing protocols in dental laboratories.
- Acceptance testing and incoming inspection by procurement teams and distributors.
- Reference for regulatory compliance, clinical evaluation and certification bodies assessing dental materials.
- Guidance for testing laboratories performing mechanical, thermal and radiological tests.
