By means of the acquisition of the patient’s
CT scan at a pitch of no more than 2mm, it is possible
to make a computerised 2D model of the bone problem
where intervention is necessary.
Thanks to a sophisticated “mirroring”
technique, the curvature of the implant is then constructed,
thus obtaining a three dimensional replica of the
prosthesis to be applied.
The special product engineering software used allows
not only for perfect reconstruction giving excellent
aesthetic results, but also for the simulation of
the adaptation of the prosthesis in vivo.
 The
computer model is then used to obtain a stereolithography,
i.e. a prototype of the final prosthesis, which can
then be assessed by the surgeon before the operation.
Lastly, in the production of the final implant, PMMA
is injected at controlled pressure into the “custom
made” mould in order to obtain reduced macroporosity.
This procedure results in high mechanical strength
and a reduced risk of bacterial adhesion, with consequent
decreased probabilities of infection of the implant.
At this point, two perfectly identical prostheses
are made (one of which will be used as a “safety
copy”), sterilized by EtO.
