Abstract

A digital measurement method for lowinvasive clinical diagnosis of metallic prosthesis osseointegration was proposed. Electrical impedance spectroscopy is exploited to characterize the quality of the interface bone-prosthesis tissue. In this paper, in vitro and in vivo experimental results of the application of the proposed method to the evaluation of osseointegration of metallic implants used for percutaneous fixation are shown with a specific clinical case study in audiology. In particular, a cochlear implant BAHA ® from Cochlear TM with direct bone conduction was used. In vivo measurements were performed on children with fixtures implanted respectively 7, 9, and 18 months before the test.
