Paper Abstract
The achievement and the maintenance of dental implant stability are prerequisites for the long-term success of the
osseointegration process. Since implant stability occurs at different stages, it is clinically required to monitor an implant
over time, i.e. between the surgery and the placement of the artificial tooth. In this framework, non-invasive tests able to
assess the degree of osseointegration are necessary. In this paper, the electromechanical impedance (EMI) method is
proposed to monitor the stability of dental implants. A 3D finite element model of a piezoceramic transducer (PZT)
bonded to a dental implant placed into the bone was created, considering the presence of a bone-implant interface
subjected to Young’s modulus change. The numerical model was validated experimentally by testing bovine bone
samples. The EMI response of a PZT, bonded to the abutment screwed to implants inserted to the bone, was measured.
To simulate the osseointegration process a pulp canal sealer was used to secure the implant to the bone. It was found that
the PZT’s admittance is sensitive to the stiffness variation of the bone-implant interface. The results show that EMIbased
method is able (i) to evaluate the material properties around the implant, and (ii) to promote a novel non-invasive
monitoring of dental implant surgical procedure.
