medical application with
interaction of the biologic
system.

Osteointegration of Bio-Oss
Bone
Bio-Oss
The Bio-Oss® particles are
integrated in the newly
formed lamellar bone.
Time: min. 6 months
The matrix produced
by Bio-Oss®, facilitates
the ingrowth of blood
vessels, and the
migration of osteoblast
cells.
So develops the cell-rich
woven /reticular/ bone.
The highly porous
Bio-Oss® ceramic
stabilizes the
coagulum
