Abstract: A dental implant identification system of the non-contact type has a dental implant (260) and a non-contact tip (262) of a reader probe (263). The dental implant (260) has a non-contact RFID tag (264), which is cylindrical in shape, positioned immovably inside an open cylindrical cavity (266) within the main body of the dental implant (260), The non-contact tip (262) of the reader probe (263) includes, at its leading end, a reader antenna coil (268) (which is a transmitter receiver element in the form of a power coil), a coil positioning spring (270) and a reader positioning collar (272). The reader antenna coil (268) is electrically connected to, and receives its power through, wiring (273) from a match circuit (274) along which current flows. In use, the contact tip (262) of the powered on reader probe (263) is inserted through the opening of the cavity (266) of the dental implant (260) until further insertion is prevented by the reader positioning collar (272) becoming wedged ill the opening, and the tag antenna coil (276) and the reader antenna coil (268) are magnetic field coupled. The non-contact RFID tag (264) is passively powered by electromagnetic wave transmissions from the reader antenna coil (268) of the reader probe and received by the tag antenna coil (276).
