Using RFID Tags to Make Teeth

Roland Piquepaille writes "If you live in France, and soon elsewhere in Europe and in the U.S., and if you need a dental prosthesis, chances are good that RFID tags are involved in the manufacturing process, according to this article from the RFID Journal. The tag is embedded by the dental lab in the cast which will be used to make the prosthesis. Then it is used to record the whole history of the crown, a process requested by a European sanitary regulation. Before delivering the bridge to your dentist, all the data is copied to a smart card that will be given to you. The company is also studying the idea to put directly the tag inside the prosthesis. Maybe one day, when your dentist installs your new bridge, you'll also be the owner of a deactivated RFID tag inside it. This summary contains more details and a picture of the RFID tag used to record the life of your next crown."

    Prosthetics are already tracked with a number. If you get a knee replacement there is a specific serial number on the replacement part.

    Even breast implants have tracking numbers.

    While using a RFID tag would make things easier it is by no means a requirement that this needs to be done.

    that the RFID could be included in the prosthesis. The first and second casts are made at relatively low temperatures. But the following step in making a porcelain bridge or crown (obviously these couldn't be embedded into metal and still work) involves a baking process for hardening the ceramic after grinding and for fixing the enamel layer. This is done at up to 1000 degrees C (again, depending on the materials), a temperature far above what most semiconductors can survive, even when inactive.

    Sadly, this is the first /. article that I can comment on using my experience designing porcelain furnaces.
