Hi,

You can do something like what is shown in the following movie using Slicer Segment Editor Modules

A good starting point is to review the segmentation tutorials

[https://www.slicer.org/wiki/Documentation/Nightly/Training#Segmentation](https://www.slicer.org/wiki/Documentation/Nightly/Training#Segmentation)

Let us know if you have specific questions after you review the tutorials and try out the Segment Editor Module to do the extraction

Best,  
-Andinet

As @Andinet_Enquobahrie suggested above, you can use Segment Editor module in Slicer to do this. For example, segment a tooth using “Grow from seeds” effect then remove it (replace it with voxel value corresponding to air) using “Mask volume” effect.
