Xilloc-CT-Bone®: Real Bone from the 3D Printer


CT-Bone®: Real Bone from the 3D Printer
Patients requiring skeletal augmentation, for example those with facial asymmetry resulting from either trauma or congenital defects, would be helped best with a bony implant made to match their anatomy. Therefore, Dutch company Xilloc, specialist in patient-specific implants and Japanese company Next21, specialist in ceramics are going to collaborate on the 3D printing of CT-Bone®.

Typical bone augmentation implants are made from alloplastic materials, or the patient’s own bone is cut and repositioned. CT-Bone® is a bone-like implant that can be 3D printed and is converted to real bone by the patient.

After taking a CT-scan of the patient, a patient-specific implant is designed by our biomedical engineers in collaboration with the surgeon. This design perfectly fits on the anatomy of the patient, ensuring good bone-to-implant contact and facilitating bony ingrowth. The design is 3D printed in calcium phosphate, the main constituent of natural bone. When implanted, CT-Bone® unifies with the patient’s own bone in the next months.

Unlike other 3D printed ceramics, CT-Bone® does not require a thermal process to increase mechanical strength and therefore also displays better bony fusion. The process of 3D printing allows complex shapes and controlled porosity, similar to natural bone.
