Operating system: Windows 10
Slicer version: 4.10.1
I want to create models for mandible and teeth from a CBCT scan. After importing the DICOM file to 3Dslicer and completing the segmentation process I used segmentations/export to export the segmentations as STL models. Then I import those STL files into Meshmixer and I found out the models have intersections! (the surface of the teeth model penetrates the surface of the bone model as you can see in the image). I noticed that 3D Slicer uses the Marching Cube algorithm in order to calculate surface mesh from the label map volume, which might be the reason why the estimated surface of one segment is penetrating the other segment’s surface.
-I would like to know is there any way to solve this problem and avoiding any penetration in the exporting files?
- The voxel size of my data is 0.3x0.3x0.3mm. I have tried to create an empty space with 0.5mm width by shrinking the margin of the teeth segment by 0.5mm, and then exporting the models. Hopefully, my models do not have any intersection with the empty space between them. However, I am curious to know whether there is any better way to avoid such intersection problems.
Thank you in advance for your help
