Osteogenesis X-ray dynamics when filling shaft bone defects of the leg with a bioactive meshy implant

The bioactive meshy implants of five (5) adult dogs were tested pre-clinically in order to fill circular tibial defects of 2.0-cm extension. The implants were made from Ti6Al 4V titanium alloy powder with calcium-phosphate coating, applied by the technique of microarc oxidation. The dynamics of the implant osseointegration with bone tissue was studied by X-ray method. A stable bone-implant block was formed 1.5 months after surgery. The conclusion was made that the X-ray method in these experiments was not sufficiently informative because it did not allow evaluating reparative osteogenesis process directly in the defect cavity projection. It is possible to obtain objective data about the processes of osseointegration and osteoinduction under the created conditions by using morphological methods after appropriate preparing the samples of the anatomic preparations.
