In an operation that's the first of its kind, doctors have created a new jaw using a 3D printer.
The patient, an 83 year old Dutch woman, required the surgery after suffering from a chronic bone infection. For the first time doctors were able to literally 'print' a jaw bone implant for the operation using a 3D printer. "Once we received the 3D digital design, the part was split up automatically into 2D layers and then we sent those cross sections to the printing machine," said engineer Ruben Wauthle. "It used a laser beam to melt successive thin layers of titanium powder together to build the part."
The transplant was carried out in June in the Netherlands, but is only now being publicised. The implant was made out of titanium powder - heated and fused together by a laser, one layer at a time. Technicians say the operation's success paves the way for the use of more 3D-printed patient-specific parts.
