Minimum Pre-Requisite Functions: Trim Model
Recommended: External shape of splint be already established
[learn_more caption=”Basic Use” state=”open”] Passivity offset calculated an offset surface from the Trimmed Model and allows for splint to not bind once fully seated (This is different than undercut removal). Different offsets will be needed based on your manufacturing technique, variation among printers/materials or to compensate for slight inaccuracy in the scan. To use it, press the “Passivity Offset” button, and choose the thickness of the offset that is desired. Bigger numbers means a more “sloppy” fit once the appliance is fully seated.
When the operator is done (5 to 20 seconds), you will be presented with a view of a the Passive Spacer and the Splint Model. It should extend slightly past where you marked the margin for your splint

Multiple Offsets for Same Case
To make multiple splints at different offsets. Save a checkpoint blend file right before Finalizing. Finalize and export the splint at the first Passive Offset. File -> Open and open your checkpoint file. Re-calculate the Passive Offset by pressing the button and choosing the new value, Finalize -> Export. If you
Measuring the Thickness
If you want to verify your offset, you can use ‘Alt + B’ to take a slice view and look at your Passive Offset on the Splint Model. You will notice that the offset extends much more into the model. This is to help ensure boolean success in later steps. You can also use the builtin Blender “Ruler/Prortractor.” Press “Space Bar” and type “Ruler.” Click “Ruler/Protractor.” Click and drag on your passive spacer and you will see a ruler start to appear on the screen. Press ‘Esc’ to exit ruler/protractor mode.
