Pure-phase -tricalciumphosphate (>99% -TCP) Interconnected porosity Porosity > 50% Osteoconductive 100% synthetic Spherical granules 315µm - 1600µm Simultaneous resorption

to bone growth Complete resorption proven

Properties

10

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

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

Indications

Filling of bone defects after extirpation of cysts Defects in corrective osteotomy Defects after the extraction of a tooth Sinus floor elevation surgery Periodontal and peri-implants defects Defects after harvesting of autogenous bone Augmentation of alveolar bone
