Abstract
The stability of a dental implant is a prerequisite for supporting a load-bearing prosthesis and establishment of a functional boneimplant system. Reliable and noninvasive methods able to assess the bone interface of dental and orthopedic implants (osseointegration) are increasingly demanded for clinical diagnosis and direct prognosis. In this paper, we propose the electromechanical impedance method as a novel approach for the assessment of dental implant stability. Nobel Biocareimplants with a size of 4.3mm diameter 13mm length were placed inside bovine bones that were then immersed in a solution of nitric acid to allow material degradation. The degradation simulated the inverse process of bone healing. The implantbone systems were monitored by bonding a piezoceramic transducer (PZT) to the implants abutment and measuring the admittance of the PZT over time. It was found that the PZTs admittance and the statistical features associated with its analysis are sensitive to the degradation of the bones and can be correlated to the loss of calcium measured by means of the atomic absorption spectroscopy method. The present study shows promising results and may pave the road towards an innovative approach for the noninvasive monitoring of dental implant stability and integrity.
