Medical and 3D printing in ceramics, a new story that is being written…
The medical sector has always been interested in cutting-edge technologies, which is why 3DCeram has been working with biomedical players since 2005. For more than 15 years 3D printing has continued its development to offer today a level of maturity that can now meet the requirements of the biomedical field. Additive manufacturing for ceramic is ready to integrate the supply chain of the medical field.
3DCeram has developed its mastery of 3D printing ceramics process, its machines, materials and services as maintenance and trainings. The large range of printers from C100 EASY FAB to C3600 ULTIMATE, depending on production capacity requirements for biomedical devices or dental.
On the other hand, specific formulations have been developed over the years for osteointegration and biocompatibility, like HAP (Hydroxyapatite) or TCP (Tricalcium Phosphate) or Alumina Toughened Zirconia (ATZ) for medical application.
To integrate 3D printing in the medical supply chain certifications are essential. So 3DCeram has established a partnership with Gregory Nolens to carry out 3D ceramic printing in the biomedical field.
This partnership will bring the biomedical players a complete expertise and know-how to enable them when integrating a 3D printing unit in their supply chain.
On the other hand, Gregory will assist the customer equipped with a Ceramaker printer to get the unavoidable certification, dedicated to medical devices in different fields like: • dental, • orthopaedic, • maxillofacial, • plastic surgery
3DCeram-Sinto and Grégory Nolens, with their experience and expertise, will accompany the companies, which wish to integrate 3D, in the different stages of the process, in order to integrate this new printing technology.
Implants and bone substitute
3DCeram leverages SLA 3D printing technology for more than 10 years to manufacture custom-made or small series of bone substitutes (intervertebral cages and tibial osteotomy wedges) and cranial or jawbone implants. • Biocompatible • Osteoconductor • Good mechanical properties • Medium-term resorbable • Easy to stock • Easy to work
A unique process for porosity control
Additive manufacuring makes possible to control the location and geometry of the pores of ceramic substitutes, unlike implants that are made porous by adding organic foam or porogens. Porosity structured in three dimensions and constant diameter of the fully interconnected pores promote osteointegration and mechanical strength of substitutes. Compressive mechanical strength is between three and five times higher than that of conventional porous structures. The risk of post-operation inflammation caused by micro debris that breaks when handling and positioning the implant is greatly reduced.
Reconstructive surgery: the surgeon adjusts the medical device to the patient.
3DCeram has developed a unique stereolithography based technology for the manufacture of custom-made bioceramic cranial or jawbone implants named BioCranium®. Our custom hydroxyapatite ceramics implants allow the replacement of the important osseous defects of the dome of the skull and the jawbone part, thus guaranteeing the protection of the subjacent anatomical structures. This custom method is also used in reconstructive surgery for the patients carrying of a loss of cranio-facial osseous substance, after a surgical act. The ceramic implants are an alternative to the osseous grafts which very often come from the patient himself, and thus avoid him additional pains.
The surgeon remains at the heart of the operation that he controls by adjusting the medical device to the pathology of his patient. The 3D digital model of the bone defect to be repaired is made directly using the patient’s pre-surgery scan and in accordance with the instructions from the surgeon. He analyzes and decides on the right shape, location and structure of the porous zones adequate to support the integration of the prosthesis. The implant, accurate to one tenth of a millimeter and made in a very short time, is ideally suited to the morphology of the patient for a high quality reconstruction.
Foster osteoconduction and bone remodeling.
Calcium phosphates, such as hydroxyapatite or tricalcium phosphates, are the synthetic materials closest to bone. They are widely renowned in medical circles for their osteoconductive properties, especially when the macropores size and porosity of interconnection are controlled. They have minimal risk of rejection. Thanks to this controlled porosity, bone substitutes made by 3DCeram are fully biocompatible
