| Summary: | 3D printing of mandible is important for pre-operative planning, diagnostic purposes, as well as for education
and training. Currently, the processing of CT data is routinely performed with commercial software which increases the
cost of operation and patient management for a small clinical setting. Usage of open-source software as an alternative to
commercial software for 3D reconstruction of the mandible from CT data is scarce. The aim of this study is to compare
two methods of 3D reconstruction of the mandible using commercial Materialise Mimics software and open-source Medical
Imaging Interaction Toolkit (MITK) software. Head CT images with a slice thickness of 1 mm and a matrix of 512x512
pixels each were retrieved from the server located at the Radiology Department of Hospital Universiti Sains Malaysia. The
CT data were analysed and the 3D models of mandible were reconstructed using both commercial Materialise Mimics and
open-source MITK software. Both virtual 3D models were saved in STL format and exported to 3matic and MeshLab
software for morphometric and image analyses. Both models were compared using Wilcoxon Signed Rank Test and
Hausdorff Distance. No significant differences were obtained between the 3D models of the mandible produced using
Mimics and MITK software. The 3D model of the mandible produced using MITK open-source software is comparable to
the commercial MIMICS software. Therefore, open-source software could be used in clinical setting for pre-operative
planning to minimise the operational cost. |
