Abstract:
A system for locating an artificial denture lost within an medical care institution comprising:a passive device responsive to an excitation electromagnetic field, the passive device being mounted on the artificial denture, the passive device comprising means for emitting an electronically detectable signal in the presence of the excitation electromagnetic field, the passive device being encapsulated in a denture material that is transparent to the excitation electromagnetic field with the denture material isolating the passive device from contact with the oral cavity of a wearer of the artificial denture; a transmitter for transmitting the excitation electromagnetic field; a receiver for detecting the signal emitted by the passive device in the presence of the excitation electromagnetic field so that the lost artificial denture can be located within a zone with a detectable range of the receiver, and computing means configured as a database cross referencing specific dentures with patients in the medical care institution who own the specific denture.
