Denture marking & its methods :
Forensic identification based on assessment of prosthodontic appliances is assuming greater significance , as labeling of dentures and other prosthetic appliance could provide vital clues
( 6,7,8 ) for patient identification .
The various techniques for denture marking are : 1 . Surface marking 2 . Engraved fixed restorations 3 . Lenticular cards 4 . Bar coding 5 . Microchips
1 . Surface Marking : Personal identification details are printed on paper with a laser printer . On the denture base palatal aspect , a depression approximately 1 mm deep is cut . This label is placed into the designated space , and then covered with an auto polymerizing acrylic resin . The acrylic resin is trimmed and finished in the usual manner .
2 . Engraved fixed & removable restorations : The incorporation of an identification mark on a cast partial denture framework would ensure identification even in more extreme situations , such as fires and traffic accidents .
3 . Lenticular Card : It is a technology in which the lenticular lens is used to produce images with an illusion of depth , morphology or the ability to change or move as the image is viewed from different angles . Lenticular printing is a multistep process consisting of creating a lenticular image from atleast two or more existing images , and combining it with a lenticular lens . Each image is sliced into strips , which are than interlaced with one or more of the other images . These are printed on the back of a synthetic paper and laminated on the lens .
4 . Bar Coding : Automatic identification using barcodes incorporated into dentures has been developed . Barcode systems can contain large amounts of data . However , the scanning of barcodes may be difficult due to the opacity of the acrylic resin , and for this reason the use of clear acrylic resin is recommended with this system .
5 . Micro Chips : Radio Frequency Identification ( RFID ) is a method of identifying by using radio waves . It consists of a data carrier , referred to as tag and a reader with an antenna . Tag consists of a microchip with patient ’ s information . Reader reads the information contained in the tag . First , program the tag by connecting to the computer then incorporate the programmed tag into the channel on the externa posterior buccal surface of the denture .
