Margin Line

The Gingival Margin Line tool allows you to draw the gingival margin line on scanned results and export it in a proprietary format. The gingival margin data can be imported into software like ExoCAD.

draw the gingival margin line, you must first define the relevant preparations in the case information. Without this, the feature cannot be used.

Start by selecting the teeth where you want to draw the gingival margin line, then proceed with the drawing on the model. Changing the model color to gypsum is helpful for observing the gingival margin line's characteristics. Left-click to add control points, and hold the right mouse button to rotate the model.

The gingival margin line must be closed. If you make an error while adding control points, you can undo the last point using "Ctrl + Z" on your keyboard. After the gingival margin line is closed, you can still modify it by dragging the control points.

Edentulous Margin Line Case Application:
When opening the margin line tool, the "Edentulous" button can be selected to outline the margin line of a half-arch model.

Previously, the margin line for edentulous cases was typically drawn manually by doctors using a pencil on a plaster model to indicate the denture coverage area, which was then sent to the lab without an accurate, separate .xyz file. This feature enables the digital drawing of margin lines, and the results can be used as a reference. Integration with Exocad is not required.
