Scientists 3D-print artificial


jaw for cancer patient


In Skyfall (2012), Raoul Silva is the Bond villain
with a jaw implant that helps him breathe. A
jaw implant allowed a real patient, Shirley Anderson,
to have a new face prosthesis after he lost his
jawbone due to a cancer tumour in his tongue.
Doctors from Indiana University in 2012 made a
prosthesis for Shirley Anderson using a 3D printer.
They CT-scanned Anderson’s face and subsequently
used the data to create a model on a computer, using

this to design a replacement that was printed by
means of the stereolitography method. A
stereolithography printer consists of a tank with
liquid plastic and a laser underneath. The laser
‘draws’ the required shape from below layer
by layer, and the light makes the liquid material
harden. In the process, the solid replacement is
gradually lifted out of the tank. This process
successfully sculpted a new jaw for Shirley Anderson.

Patients can now get a 3D-printed substitute for lost skin and
limbs. Laser light creates accurate plastic replacements.

Veterans experience familiar war situations as part
of a new treatment to ease PTSD symptoms.

The villain of Die Another Day (2002)
suffers from insomnia, and treats
himself with a virtual reality mask. Doctors
are using a similar method to treat war
veterans suffering from PTSD, which can
cause anxiety and nightmares.
Dutch scientists in 2013 introduced a PTSD
treatment method involving the reactivation of
traumatised soldiers' emotions via virtual
reality. The veteran walks on a treadmill while
watching a situation from the war in Afghanistan.
A red ball moves about the screen, indicating
numbers that the veteran says out loud. The
task activates his working memory as the
memory of the trauma is activated. The brain
then uses fewer resources on remembering the
trauma in a stressful way, and the memory can
be ‘re-saved’ in a less traumatic version.
