STB PD CEN/TR 12401:2025 — Dentistry — Guidance on the classification of dental devices and accessories. This document is a national adoption (STB PD) of the CEN Technical Report CEN/TR 12401:2025 and provides practical guidance on applying the medical-device classification rules to products used in dentistry, including devices and accessories intended for dental diagnosis, treatment and care.

Abstract

This technical report offers interpretative guidance and worked examples to help manufacturers, notified bodies and national authorities classify dental devices and associated accessories under the classification rules of Regulation (EU) 2017/745 (the Medical Device Regulation, MDR). It clarifies borderline cases frequently encountered in dentistry, explains the application of relevant classification rules, and provides illustrative device examples to support consistent regulatory classification across national markets. Published as a CEN/TR in 2025 and adopted nationally as STB PD CEN/TR 12401:2025.

Scope

This technical report gives guidance on the interpretation and application of the classification rules set out in Regulation (EU) 2017/745 for dental devices and accessories. It covers classification principles applicable to a wide range of dental products (including instruments, handpieces, restorative materials, prosthetic components, and accessories), addresses borderline and combination-product scenarios encountered in dentistry, and supplies worked examples to promote consistent classification decisions by manufacturers, conformity assessment bodies and national competent authorities.

Key topics and requirements

• Interpretation of MDR classification rules specifically for dental devices and accessories.
• Worked examples and case studies showing classification decisions for common dental items.
• Guidance on borderline cases and accessory vs. device distinctions in dental practice.
• Advice on classification of combination products and devices incorporating substances or software.
• Notes on documentation and regulatory pathways related to classification outcomes (e.g., conformity assessment routes implied by class).
• Recommendations for consistent national implementation and decision rationale to support auditing and regulatory review.

Typical use and users

Primary users are manufacturers and design/quality teams developing dental devices and accessories, regulatory-affairs specialists, notified bodies and conformity-assessment personnel, national competent authorities, and professional bodies seeking clarity on device classification under the MDR. The report is also useful to product managers, regulatory consultants and dental-care organisations involved in procurements or compliance assessments.
