Truly comprehensive solutions to produce bioceramic implants
23 July 2020
3DCeram has developed a technology based on stereolithography for the production of bioceramic skull or jawbone implants. This technology allows to control the porosity, use calcium phosphates as materials and adapt the implant to the patient.
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
