Dear All,

We are glad to announce the availability of DentalSegmentator, a new 3D Slicer extension for automatic segmentation of dental CT and CBCT scans. It is now available in the latest Slicer 5.7.0 preview release.

This tool is based on a nnU-Net model trained and evaluated on more than 700 CT and CBCT scans. It has been shown to be robust in most situations, even in the presence of metallic artefacts or varying field of views.

It generates the following segmentations :

  • Maxilla & Upper Skull
  • Mandible
  • Upper Teeth
  • Lower Teeth
  • Mandibular canal

Segment editor tools and model export features are directly available in the module. The extension does not require a GPU, but a CUDA-capable GPU is needed for fast results (around 1-2 minutes).

Thank you very much for creating the module, but it doesn’t work. I have the latest version of the program installed, as well as all the required plugins. However, when I click ‘apply,’ it just keeps loading and doesn’t do anything. I’ve left it running for up to an hour, but nothing happens.

Awesome work. Congrats!
I would like to know if it is possible to set parameters so we can run it on a 2gb NVIDIA laptop GPU.
I run it on CPU just fine (it takes several minutes). But I ran out of memory when tried to run on CUDA.
