The implants are created from CT-scans and then printed by a 3D printer. The material is compatible with the anatomy of the body so much that they will actually turn to real bone eventually. Not only that but you can plant them all over your skull augmenting anything from your zygos and orbital rims to the brow ridge and the jaw.
Quote:The manufacturing of CT-Bone involves printing the designed implant using calcium phosphate, the primary constituent of natural bone. The advantage is that when this is implanted, the patient’s existing bone fuses with it just as it would with natural bone and unifies in a few months. It’s a bone-like implant that allows bone to grow naturally into it.
