OSferion is a white porous material composed of β-tricalciumphosphate. It is intended to fill bony voids or gaps caused bytrauma or surgery that are not intrinsic to the stability of thebony structure. OSferion is to be used as a bone replacementmaterial and has properties that allow it to be replaced byautogenous bone after implantation.The porosity of OSferion is 60%.Products are supplied in wedges and trapezoids.
A sterile bioabsorbable device made of synthetic material intended to be implanted into the body to provide osteoconductive bone-tissue scaffolds, and sometimes osteovascularization, to replace bone lost through trauma, surgery, or pathological conditions (e.g., osteoporosis). It may be made of ceramics (e.g., tricalcium phosphate or hydroxyapatite), bioactive glasses/minerals/metals (e.g., strontium), or bioabsorbable polymers. It is used to fill cystic defects, repair fractures, and/or extend autogenous bone grafts and is typically provided as cancellous blocks, chips, or granules of varying sizes, or mouldable/fluid materials.
