A sterile bioabsorbable device made of synthetic bone substitute materials (e.g., ceramics such as tricalcium phosphate or hydroxyapatite) combined with bone growth factors (e.g., bovine collagen) implanted into the body to provide osteoconductive bone-tissue scaffolds to replace maxillofacial and/or mandibular bone lost through trauma or dental surgery. It is used to fill bone cavities and defects to promote the ingrowth of endogenous bone for skeletal reconstruction and/or augmentation. It is typically provided as sterile cancellous blocks, chips, or granules of varying sizes, or mouldable materials.
