Dental implant detector using constant current source and its detecting method

A dental implant detector using constant current source comprising:

• a detecting sensor, a detecting sensor socket and an implant locator;
• the detecting sensor socket is connected with the detecting sensor and the implant locator at two ends respectively;
• the detecting sensor is built with a PCB base, detecting coils mounted on the layer and plane of the PCB base, a center hole at the middle of the base and via holes which connect the coils on the layer and plane of the base;
• the detecting coils are two involute racetrack copper coils mounted on the layer and plane of the PCB base;
• the coil on the plane is smaller than that on the layer by 0.1 mm both laterally and longitudinally;
• electricity is supplied to the coils through the electrode connected with the power supply;
• the implant locator is built mainly with a CPU with power supply, a constant voltage module, a status display control module and a frequency conversion module;
• the detecting sensor socket is connected with the detecting sensor at one end and with the front tip of the implant locator at the other end;
• the PCB is connected to power supply through the detecting sensor socke;
• the constant voltage module, status display control module and the frequency conversion module are connected with the CPU;
• the PCB is connected with the CPU through the detecting sensor socket;
• the frequency conversion module controlled by the CPU will produce different frequency ranges according to the gears chosen and implement scanning with increasing frequency within the chosen range.
