This
is beginning to become really important.
This is real skull replacement with a printed structure. What makes this exciting is that we are
simple predictable steps away from an artificial fibrous matrix including
graphene reinforcement that is either formed directly with natural bone making material
or friendly enough to allow bone growth within the matrix.
If
we can then do that, the next obvious step is to apply that to all bones in the
body and to develop surgical replacement to work with that ability. As well, if we are able to replace bones
outright, then putting in hugely stronger bones makes very good sense.
As
well, the skull can be significantly thinned down and slightly enlarged to
allow a significant increase in brain size without significantly altering the human
appearance. This may well prove
advantages as well. Size is not supposed
to matter too much and wiring density certainly does. However there is some association that needs
to be clarified and possibly accommodated

Woman Has Her Skull Replaced With A 3-D-Printed
Plastic One
The most significant skull prosthetic to date

A woman with a rare bone disorder has had much
of the top of her skull replaced with a 3-D printed plastic piece, Wired U.K. reports. Three months later, she's
symptom-free and back to work.
The woman's condition made her skull increase in
thickness, giving her severe headaches and affecting her eyesight. The surgery,
performed at the University Medical Center Utrecht in the Netherlands, gave the
woman a replacement that closely matched the original shape of her skull.
"It is almost impossible to see that she's ever had surgery," her
lead surgeon, Bon Verweij, said in a statement from the university.
Verweij's team has used 3-D printing to replace
some portions of skulls before, but never to this extent, Wired U.K. reports.
You might see more such stories in the near
future. While researchers are still working on 3-D printing soft tissues that are
safe for transplants, 3-D-printed bony parts have already shown up in specific
surgeries. As in the Utrecht case, doctors often emphasize how personalized
such replacements can be.
Three years ago, a British man who had much of
his pelvis removed got a replacement 3-D printed in titanium, the Ottawa Citizen reports. Printed titanium implants
are made by spitting out titanium powder that's then fused by a laser beam. The
man's doctor thought a printed replacement would fit better than a standard,
handmade one. The man now walks with a cane, the Citizen reports.
In June 2011, a patient in Belgium received a 3-D printed titanium jawbone replacement.
This was the first total lower jawbone replacement made to match a specific
patient, the BBC reports.
And just last year, Livescience reported a
Connecticut-based company received U.S. Food and Drug Administration approval
to market a plastic replacement for 75 percent of the skull.
