D3Splint Version: v0.4.0 and later

Minimum Pre-Requisite Functions: Splint Shell, Survey Model,

Recommended: All external shape, occlusion and structural components of the splint be established first.


[learn_more caption=”Basic Use” state=”open”]  The Refractory Model is a model that has been altered to selectively remove undercuts, and to create a compensation gap to control the fit, retention, friction of the appliance.


When the operator is done (35 to 55 seconds), you will be presented with a view of a the refractory model and a checkbox will appear next to the operator.

The image below shows how the compensation gap and selective undercut blockout are combined to create the refractory model.  In previous versions, the compensation gap and undercut removal were calculated separately, however to increase efficiency and stability, they are calculated together so the chance to visualize them separately as a normal part of the worklfow is now gone.  See these links for how to still access the old Passivity Offset and Remove Undercuts functions.

Multiple Refractory Models for Same Case

It can be advantageous to make multiple splints with different amounts of retention for the same case (for example to calibrate your process).  Save a checkpoint blend file right before Finalizing. Calculate your ‘Refractory Model’ at the desired settings, Finalize and export your splint.  Then re-open your checkpoint and repeat at desired alternate settings.

You can still access the Passive Offset and Blockout Undercuts by using the spacebar menu and searching for “Create Splint Spacer” and “Blockout Trimmed Model2.”
