adaptation of titanium plate
surgery of the newborn with a craniosynostosis are twofold: (1) Decompression of
the intracranial space (to reduce intracranial pressure, to prevent visual problems,
and to permit normal mental development) and (2) Achievement of satisfactory
craniofacial form. The different methods of osteotomy for cranial vault remodeling
can be simulated on the 3D model. The introduction of SL for cranioplasty of
newborns and infants has reduced operating time significantly [ 22 ].
Distraction Osteogenesis
Stereomodels have proven to be highly beneficial in cases of distraction osteo-
genesis. They help in the planning, positioning of the device, placement of the
osteotomy cuts, and predicting and visualizing the end results of the treatment.
They also help in patient education and better understanding of the treatment
procedure.
Conclusion
• The use of 3D models in oral and maxillofacial surgery has significantly
improved predictability of clinical outcomes when compared to similar treat-
ments without its use.
• Total operating time is reduced which has the benefit of decreasing the duration
of general anesthesia and reducing wound exposure time.
• Assessment of extensive traumatic and pathologic defects in three-dimensions
prior to surgical reconstruction.
• The models are useful in the design and fabrication of custom prosthesis and
sizing of bone grafts, distraction osteogenesis, and patient education.
