Bone formed around implant was characterized and grouped into three categories by Nakada et al. and Suwa et al. In order to clarify these bone tissues, we have utilized radiography with a newly developed wavelength tunable and highly parallel Parametric X-ray (PXR) in the Laboratory for Electron Beam Research and Application (LEBRA) of Nihon University. Methods: Ti-alloy implants modified with coating or blasting were used in this study. These materials were implanted in the tibia of rabbits. After 1, 2 and 4 weeks of implantation, non-demineralized polished thin sections were cut. PXR was generated by a LINAC in the LEBRA of Nihon University. X-ray wavelength was tuned from 7KeV, 0.177nm to 16KeV, 0.0775nm; irradiation: 900 sec; sample-detector distance: 7.5mm and recording film: Fuji Film Imaging Plate. The obtained images were processed by NIH image analyzer. Results: PXR radiography showed the clear difference between the newly formed bone and the compact bone. Estimated percentage for the newly formed and pre-existing bone were 8.27% and 20.9%, respectively. Conclusion: LEBRA-PXR could be a good tool for the quantitative analysis of bone formation.
