Changes in the methods, materials, and descriptions of denture marking

This review examines the development of denture marking from 1990 to 2025, driven by the growing need for identification in aging societies. Methods have evolved from direct techniques, such as ink and engraving, to indirect ones, including embedded quick response (QR) codes, radiofrequency identification (RFID) tags, and near-field communication (NFC) tags, which improve durability and data capacity. Materials now range from paper and photographs to metals and biocompatible laminates. Recorded information has advanced from basic personal details to encrypted digital data linked to medical records, raising concerns about privacy and ethics. The review emphasizes the need for cost-effective, standardized, and secure marking systems.
