2D barcodes: a novel and simple method for denture identification.

Several methods of denture marking have been described in the literature. However, most of them are expensive, time-consuming, and do not permit the incorporation of large amounts of information. We propose a novel and simple method incorporating 2D codes which has several advantages over the existing methods. A 2D code was generated in the dental office and inserted into a maxillary denture. The code was then read using software downloaded into a mobile phone giving access to the website containing details about the patient. The denture was also subjected to durability tests, which did not hamper the efficacy of the 2D code. 2D coding for dentures is a simple, less expensive method with the potential of storing a large amount of information that can be accessed on-site by the forensic investigator, thus allowing quick identification of the denture wearer.
