Osseointegration (OI) could be described as the modality for stable fixation of titanium implant to bone structure. The OI has become a realized phenomenon of importance in the dental and rehabilitation sciences since recently developed dentures and artificial limbs are directly attached to human skeleton by using osseointegrated implants. Previously, a study showed that bone strain generated potential (SGP) that is an electrical potential and considered to be generated by fluid flow in bone could be used as a parameter to examine the amount of OI on implant-bone interface. Since no study was performed to understand SGP behavior as a function of position for the implant-bone composite, a one-dimensional map of SGP was constructed along the longitudinal direction of the composite. For the purpose, nine electrodes including one reference were instrumented on the wet composite for the one-dimensional mapping of SGP during compression tests. The peak magnitudes of SGP were found to be significantly increased when the measurement position was approached for the interface of implant-bone. The results could indicate that the spatial SGP behavior of osseointegrated implant-bone composite could be caused by the interface of the implant-bone.
