| Cerabone® |
|
Cerabone® is a hydroxylapatite ceramic made of purely anorganic material. It can be supplied as a molding block in different sizes and as granules of differing dimensions.
The osteoconductive properties of Cerabone® make it suitable as a bone replacement material for permanent filling in or reconstruction of congenital or acquired bone defects and for increasing volume in spongiosaplasty.
Cerabone® has a range of advantages compared with other hydroxylapatite ceramics:
|
|
 
| Spongiosa structure, with interconnecting macroporous and microporous pore system, is largely identical to that of human bone. | | Low porosity fluctuation and highly uniform spongy structure make for higher stability (pressure and shear resistance) and greater load-bearing capacity than comparable ceramics. This is increased still further once the bone has built through. | | Optimal pore width (100–1,500 µm). The literature gives a pore width of at least 50 µm for problem-free integration of implant and bone. With Cerabone®, complete bone building throughout and integration is possible. | | Particularly high degree of purity of the hydroxylapatite structure. For example, almost complete reduction of out of phase calcium oxide content. This also improves the material’s mechanical stability considerably. | | Cerabone® molding blocks are available in larger sizes than other hydroxylapatite ceramics (up to 20x20x40 mm). So even elongated bone defects can be bridged or treated with one continuous molding block instead of with two or more molding blocks placed next to each other. | | Easy intraoperative working (molding) of the molding block. Cerabone® can be adjusted optimally to the particular bone defect using common surgical instruments (e. g. files, pincers). | | Cerabone® is reasonably priced. | | Cerabone® has excellent biocompatibility. |
The source material for the production of Cerabone® is bovine spongy bone. However, there is no risk of immunological reactions or of transmission of pathogens because as a result of high-temperature treatment during the manufacture of Cerabone® there is no residual protein in the finished product. The chemical composition of Cerabone® is to a very great extent identical with that of the mineral stage of human bone.

Areas of application
For permanent filling or reconstruction of aseptic bone defects:
| | |
| 1 | In accident surgery and orthopedics, e. g. for | | | filling in bone defects in the case of depressed fractures close to joints | | | filling in bone defects in the acetabulum when changing prostheses | | | filling in resection defects in the case of benign bone tumors | | | filling in bone cysts | | | filling in substance defects in the case of cartilage or bone transplants | | | filling in bone defects after autologous spongiosa removal | | | | 2 | In orthodontic and facial surgery, e. g. for |
| filling in resection defects in the case of benign bone tumors or cysts | | | filling in bone defects after radiculectomy | | | filling in alveolar defects after tooth extraction | | | filling in defects after jaw osteotomy | | | | 3 | For plastic reconstruction, e. g. | | | improving contours in the facial skeleton | | | |
To increase volume in the case of autogenous spongiosa transplants in a wide range of surgical specialisms.
