Abstract
to study the effect of the phase structure artificial calcium – phosphatic surfaces on an osteogenic differentiation of stromal stem cells in vivo on implants with the fixed range of roughness. Materials and methods. The condition of the surface was estimated by means of the measuring system Talysurf 5-120, phase structure – by the diffractometer Shimadzu XRD-7000 (Japan), element structure – by the electron microscope of Hitachi S5500. An implant from the titan of the VT1.0 brand (diameter of 12 mm, thickness of 1 mm) with the rough calcium phosphate coating applied by microarc oxidation with a column of bone marrow has been hypodermically placed to 35 mice males of the CBA/CaLac line. Histological research was carried out in 45 days. The quantitative parameters of grown tissue plates were defined by the computer morphometry. Results. The growth of coarse-fibered bone tissue with the cavities filled by red marrow has been revealed on plates with artificial surfaces. Its reproducibility was 22 % higher on surfaces composed of tricalcium phosphate and hydroxylapatite compared with amorphous calcium phosphate.
