Dutch Company Develops 3-D Printed Bone Implants (ODT Mag)
In the rapidly transforming world of medical technology, the best material available until now for 3-D-printed bone implants was titanium, or in certain cases polyetheretherketone or polyetherketoneketone. Other solutions have involved cutting bone from the patient and repositioning it where required. But for external implants, only alloplastic or non-biological materials –- metal, ceramics or plastics –- have been successfully tried and tested.
These materials when implanted have met with varying degrees of success. One particular surgery in 2011 made headlines worldwide when a 3-D printed titanium implant was inserted into the jaw of an 83-year-old woman with oral cancer.
Xilloc Medical, a Dutch medical design company that has pioneered patient-specific implants, had built a printable file for the implant from computed tomography (CT) scans and went one step further: It used complex algorithms to modify the digital jaw bone so blood vessels, nerves, and muscles could grow into the titanium implant once printed, thus allowing the body to integrate the implant to a greater extent than ever before.
Now, Xilloc is pushing the...
