Claims15
A method comprising:
- obtaining a scan STL of a patients teeth in the form of an initial .stl file,
- repairing the initial .stl file by removing unwanted scan data and repairing surface discrepancies to obtain a repaired .stl file,
- translating the repaired .stl file and adding a thickness and perimeter to create a surface re-topography .stl file, which defines an overlay;
- modifying the surface re-topography .stl file to modify the perimeter and/or reduce surface undercuts of the overlay, and
- exporting the modified surface re-topography .stl file to a device which produces 3D articles from .stl files.
