The magnetic pulse probe 2 can generate magnetic pulses under the action of the power supply 4 and the circuit board 5 for stimulating the inductor mounted on the implant and simultaneously generating a resonance frequency.

The utility model provides a pair of move degree measuring apparatu mainly used measures the instrument of implant stability on oral cavity or the craniofacial, judges whether be fit for planting tooth on the implant through the size of implant stability.

The process of measuring the stability of the implant by the mobility measuring instrument comprises the following steps:

first, a sensor is mounted on an implant.

Next, the magnetic pulse probe 2 on the momentum meter is close to the sensor on the implant.

Finally, the magnetic pulse probe 2 can generate magnetic pulses under the action of the power supply 4 and the circuit board 5 to stimulate an inductor arranged on the implant; and meanwhile, the resonance frequency is generated, the resonance frequency can directly reflect the combination condition of the implant, the chip on the circuit board 5 amplifies and converts the value of the resonance frequency into an ISQ value and displays the ISQ value on the display screen 3, and specifically, the larger the ISQ value is, the better the stability of the implant is.

The following will specifically explain the principle of how the momentum meter converts the resonance frequency generated by the magnetic pulse probe 2 into an ISQ value: after the magnetic pulse probe 2 generates the resonance frequency, the magnetic pulse probe 2 can vibrate in the induction coil, the induction coil can generate weak voltage, then the induction coil generates a voltage signal under the vibration of the magnetic pulse probe, the voltage signal is operated and amplified through the amplification module on the circuit board, and finally the voltage signal is converted into an ISQ value through the programming module on the circuit board and displayed on the display screen 3.
