Abstract
Objective. To define the rate of bone tissue integration with porous implant and quantity of calcium and phosphorus in implants extracted in 4.5 months and 1.5 years after insertion.
Material and Methods. Microstructure of specimens of porous titanium nickelide was examined by phase contrast. Chemical composition of specimens was determined by micro X-ray spectral analysis.
Results. In 1.5 years after implantation the organic tissues of various morphology, density and thickness occupied 100 % of analyzed area, and in 4.5 months 60 % of pores were filled with tissue. Calcium and phosphorus contents in surface pores were close to their natural concentrations in human bone in 1.5 years.
Conclusion. Bone – porous implant integration meets the tasks of porous device for bone defect replacement and spinal fusion. It is impossible to separate the implant from bone in 4.5 months after implantation. This demands strict adherence to surgical technique involving the use of porous implants.
