3D printing of bone similar ceramics allows for bone reconstruction with bone similar material, patient specific shape, innovative properties.
In addition to that, CERHUM has integrated new innovative functions increasing the biological and mechanical properties:
- Biologic: faster bone integration and regeneration speed
- Mechanic: increase of compression and flexural strength (patent ongoing)
Workflow - CERHUM has developed specific design approach based on porosity management, thus increasing biological and mechanical performances. By using CT-scan of the patient, a volume of the gap can be reconstructed. CERHUM includes its specific porosities design. The implant is then 3D printed, sterilized and sent to the hospital for implantation.
Target Applications - MyBone will firstly be dedicated for bone regeneration on non-loading applications, preferentially for apposition. Some indications are identified:
- Cranioplasty or Cranial Flap (neurosurgery)
- Genioplasty (maxillofacial and plastic)
- Orbital floor plate (maxillofacial and neurosurgery)
- Orthognatic (maxillofacial)
- zygomatic reconstruction (maxillofacial and plastic)
- harelip (pedriatic)
Innovative Design - Thanks to its CMO activity, Cerhum masters the 3D manufacture of bioceramics. Cerhum has improved biological performance of its materials through development. new functions increasing the biological and mechanical properties. These new functions are mainly added through management of micro and macro geometries. This approach is a combination of rules used in tissue engineering and in mechanical engineering. As some aspects are on the way to be patented, these will not be described in detail. In summary, Cerhum mix different design and densities to enhance these properties.
For custom design, Cerhum joins the services of 3D-SIDE. This will help CERHUM to integrate MyBone design in a full digital workflow, improving patient data exchange between surgeons and engineers. The partnership is consolidated through contract (exclusive and mutual) and funded R&D projects.
MyBone uses Calcium-Phosphate material with excellent biological properties that help bone cells of the patient to integrate the graft at high speed.
