Abstract In this paper,energy
dispersive X-ray spectroscopy and element ratio of implanted
bioceramic,interface and rabbit femur when the bioceramic implanted into femur
were measured by two different scan electron microscopy (SEM) EDXA modes. The
changes of element ratio and components of materials and interface implanted
into femur were compared. Thorough studies were made on the transformation of
TCP from lifeless materials into living bones after implantation,by using
SEM-EDXA,Raman spectra and infrared spectra. These results provided rich
evidence for understanding biodegration and bone bonding mechanism of calcium
phosphate bioceramics.
