Generation of three-dimensional prototype models based on cone beam computed tomography.
OBJECTIVE
The purpose of this study was to generate three-dimensional models based on digital volumetric data that can be used in basic and advanced education.


METHODS
Four sets of digital volumetric data were established by cone beam computed tomography (CBCT) (Accuitomo, J. Morita, Kyoto, Japan). Datasets were exported as Dicom formats and imported into Mimics and Magic software programs to separate the different tissues such as nerve, tooth and bone. These data were transferred to a Polyjet 3D Printing machine (Eden 330, Object, Israel) to generate the models.


RESULTS
Three-dimensional prototype models of certain limited anatomical structures as acquired volumetrically were fabricated.


CONCLUSIONS
Generating three-dimensional models based on CBCT datasets is possible. Automated routine fabrication of these models, with the given infrastructure, is too time-consuming and therefore too expensive.
