Bone Transplantation Without Rejection

Last June, an 83-year-old Belgian woman suffering from oral cancer and an infection that was eating away at her jaw received a jawbone transplant that took a team of 10 surgeons 11 hours to complete. The BBC reported on the story on Monday.
The operation was a success. Reportedly, the patient was able to eat and speak with the new jaw within hours. The operation was an even more remarkable success in one other respect: The jaw itself was manufactured with a 3-D printer.
It was built of titanium powder by a surgical team from Belgium’s Hasselt University and engineers from LayerWise, a Belgian provider of engineering and production services for industrial, dental, and medical applications.
