Histological analysis by light microscopy and fluorescence 90 days after cylinder implantation. Osseointegration is noted with both biomaterial whatever its geometry. (A) In cylinders with geometrical architecture, trabecular bone extends between the titanium septa (asterisks) from the peripheral zone of anchorage (polarized light). (B) fluorescence microscopy of the same cylinder, numerous double labels are evidenced between the biomaterial septa and in the surrounding bone. (C) Cylinders with a trabecular architecture, trabecular bone extends from the peripheral area into the cavities limited by the titanium trabeculae (asterisks). (D) Fluorescence microscopy of the same cylinder, numerous double labels within are observed in bone within the biomaterial cavities and the surrounding bone
