13. History of 3D Printing
Applications in Medicine

14. ‘To me, some of the medical
applications have been the
most surprising. I didn’t
anticipate that, and as soon as
I started working with some of
the medical imaging people, it
became pretty clear that this
was going to work. But, you
know, they told me, I didn’t tell
them.’

Simulation
“Evaluation of accuracy of 3D printed plastic models generated by rapid
prototyping in the management of maxillofacial fractures"
Dr. Yasmin Darwish
Assistant Lecturer of Plastic and Reconstructive Surgery – Cairo University

38. 3D model of a patient with left
orbitozygomatic fracture, the
plastic model shown after fracture
reduction, fixation with plates and
screws and orbital floor
reconstruction with titanium mesh.
The mesh was adjusted to reach
the posterior edge of the defect at
the most posterior aspect of floor.
The mesh measured 3.6cm in
length.
