Analytics
Identity Phase purity by XRD and IR Porosity Bulk Density Mechanical stability of granules, Abrasion Granules geometry and color Complete solubility by ISO 109913-14 Heavy metals
All production processes are validated. The following parameters are analyzed for each production lot:
11
Biocompatibility and Bone Formation
Good biocompatibility Good osteoconductivity Granules are osteointegrated Degradation and resorption via
solubility, osteoclastic action and macrophages
Resorption rate depends on implantation site (loads, fluid exchange): 9 - 15 months
Complete resorption proven in scientific study in animal model
Sheep, super critical size hole model of 8mm in femur, after 2 months
Combioss granules

pre existing bone
Dark blue: new bone

Human Histology
Osteoid (red): bone formation in progress,
Bone Formation within combioss granules

Advantages
Less material to fill defect Taking up blood Minimal generation of small
particles
Porous inside, stable outside
Complete resorption
Pure -phase >99% Purity > ASTM
