[0038] A detection rod 10 detachably connected with the composite base 20;

[0039] The detection rod 10 comprises a main rod body 11, an assembly rod body 12 and a magnet 13, the magnet 13 is installed at the top end of the main rod body 11, and the assembly rod body 12 is used to cooperate with the composite base 20;

[0040] Among them, the cross section of the main rod body 11 near one end of the assembly rod body 12 is greater than or equal to the upper surface of the composite base 20, so that when the assembly rod body 12 is assembled with the composite base 20, the main rod body 11 can cover the upper surface of the composite base 20, forming a mobility measurement structure of the composite base 20 and the dental implant.

[0041] Among them, the dental implant refers to an artificial tooth root implanted into the alveolar bone through surgical operation, used to replace the missing natural tooth root and support the upper crown.

[0042] In the embodiment, the mobility measurement structure cooperates with the mobility measurement instrument to realize the stability detection of the dental implant and the stability detection between the dental implant and the composite abutment 20 by a non-contact manner; that is, the ISQ value (implant stability quotient) of the dental implant and the composite abutment 20 is determined by using the resonance frequency to determine the stability thereof. Before measurement, the composite abutment 20 is installed on the dental implant, and the detection rod 10 is installed on the composite abutment 20, and the top of the detection rod 10 is provided with a magnet 13. In use, the mobility detection instrument excites a magnetic field, and the detection rod 10 is affected by the magnetic field and resonates with the composite abutment 20 and the dental implant. The resonance amplitude is recorded by the mobility detection instrument and calculated into the ISQ value for output, so as to quantify the stability of the dental implant and the composite abutment 20.

[0043] In the embodiment, the cross section of the main rod body 11 close to the one end of the assembly rod body 12 is greater than or equal to the upper surface of the composite abutment 20, which effectively increases the assembly contact area between the main rod body 11 and the composite abutment 20, and can more easily realize the close contact between the detection rod 10 and the composite abutment 20, reduce the gap and friction resistance, improve the channel of energy transmission, make the detection rod 10, the composite abutment 20 and the dental implant more easily resonate, and improve the accuracy of the detection result.
