Export as STL for your dental CAD software or 3D printer. Use Mask Extract in Sculpt Mode: The patched
In the digital dentistry workflow, receiving an intraoral scan (IOS) or CBCT data that isn't perfect is the norm, not the exception. Scans often contain artifacts, voids, or "cracks"—gaps in the mesh where the scanner couldn't capture data.
While specialized dental CAD software exists, Blender has become a powerful, cost-effective tool for "patching" these cracks and preparing models for 3D printing or additional design work. Export as STL for your dental CAD software or 3D printer
Here is a guide on how to approach dental crack patching in Blender, along with a crucial note on software stability.
