Through the developed internet of inspectionassessment device the digital twin model of specific implant structure can be constructed by using daily collected data besides assessing the osseointegration status of varied stages. The built model may trace the subject’s osseointegration changing. The internet of inspection device can also be applied for the health inspection of tapsdrills. Two types of inspection mechanism, electro-magneticvibro-acoustic, have been implemented in the device. The stability of structure is assessed through the computed frequency response function.

This technique features at realizing inspection device with electro-magnetic (or vibro-acoustic) mechanism. Through the developed internet of inspectionassessment device individual digital twin models for the assessed structures such as implantsmachining tools can be built up. The attached accessories for measurement need to be designed according to individual implanttool structure. Besides, a swept wavelet excitation signal vibrates implanttool structure to be inspected. Then, the stability of structure is assessed through the computed frequency response function.

This IoT device can be used for initial stabilitycontinuous follow-up evaluation after implant surgery in areas of dental, prosthetic-limbs, handfoot implants. It provides more information on the osseointegration of the implant-extremity skeletal interface clinically to help physicians effectively assess the postoperative implant stability of patients. The device can also be applied in the inspection for preventing abrupt breakage of tapsdrills on industrial production lines. By uploading data, the digital twin models of implanttool structure to be monitored can be created.
