Abstract
The formation of bone tissue in pores, and around, a block made of partially dehydroxylated porous hydroxyapatite ceramic and implanted into a rat's femur using X-ray diffraction (XRD), infrared spectroscopy (IRS) and histological methods were investigated. Structural characteristics and composition of new bone tissue formed three months after implantation, in fact, do not differ from those of the normal femur. A model of osteogenesis based on dissolution-precipitation reactions is given, taking into account peculiarities of structure, deficiency and impurity composition for the material of the implant.
