Inner and Outer Surface Settings

Video
Adjust your modeling and manufacturing settings directly in the case: inner surface in Margin Line, outer surface in Modeling.

Modeling

1. In this tutorial, adjust your modeling and manufacturing settings in Circle One. The editable elements depend on the current step: inner surface in Margin Line, outer surface in Modeling.

2. In Margin Line, click the gear icon to access the inner surface settings.

3. Adjust the retention zone and its width, the cement gap, as well as the minimum thicknesses.

4. You can also modify the compensation diameter, useful if you’ve changed your tool without updating your settings.

5. Each setting is illustrated by a diagram. Feel free to refer to it if you’re unsure about the meaning of a setting.

6. Now move on to the Modeling step.

7. In the same place, you now find the outer surface settings.

8. Circle One automatically adapts the prosthesis to the antagonist and the proximal teeth. Adjust this adaptation, or ignore an element — useful when facing a scan artifact.

9. A positive distance eases the contacts or creates an under-occlusion; a negative distance tightens the contact.

10. Finally, adjust the reinforcement thickness as needed.

11. At any time, the Reset settings button restores the settings to the values defined in your profile.

12. Every adjustment applies in real time on the prosthesis. So you can set your parameters as you model, depending on the specifics of the case. Thank you for watching this Circle One tutorial.

Frequently Asked Questions

My case is stuck while loading the Design stage.
Design
+

If your case is stuck while loading the Design stage (for example, the loader is stuck at 40%), please check your network connection. If the problem persists, please restart your case from the beginning.

Can I undo actions during the Design step?
Modeling
+

Yes. You can use the undo/redo buttons available in the interface at any time.

Can I add a border reinforcement?
Modeling
+

Yes. In the Manufacturing Settings, you can set the thickness of the border reinforcement to make it compatible with your milling tool.

‍

Can I adjust the contact points while modeling?
Modeling
+

Yes. In the Design step, you can adjust antagonist contacts in real time by smoothing or deforming them using the “Antagonist Contacts” slider.
The contacts are displayed in color through the Colormap panel, helping you fine-tune the occlusion of your prosthesis.

‍

Is the minimum thickness checked? Can I adjust it?
Modeling
+

Yes. The minimum thickness for the selected material is maintained throughout design. Circle One alerts you if the prosthesis is not insertable at the chosen minimum thickness, and offers three options: auto-adjust, manual correction, or continue without correction.

You can adjust the minimum thickness in the Manufacturing Settings or in “My Design Preferences.” Thin areas are visualized in the Colormap panel.

Why does my session end if I stay inactive during the Design step?
Design
+

If no activity is detected for a few minutes, the case automatically closes. This helps manage server load and keep Circle Credit costs optimized.

Can I go back during the Design step?
Design
+

Yes. You can use the undo/redo buttons available in the interface at any time.

Can I reopen and edit an existing design?
Design
+

Not yet. Your design cannot be saved at No, a validated design can't be reopened or edited. To start over from an existing case, use the dot menu on the case card and select "Create a new case from patient files": a new case is created with the same scans, letting you restart the design from scratch.

Can I modify the proposal? Is it safe to do so? How?
Design
+

Yes. You can freely adjust the automatic proposal using the available tools.
Thanks to our Collaborative AI, Circle One updates the model in real time and maintains key parameters such as: distance to adjacent and opposing teeth, insertion axis, minimum thickness, functional balance.

Every adjustment is simulated instantly, helping you keep a stable and reliable design as you refine it.

‍

How is the automatic proposal calculated?
Design
+

The automatic proposal is generated by analyzing your scans and taking several key parameters into account, including tooth anatomy, occlusion, proximal contacts, minimum thickness requirements, and manufacturing constraints.

Our Collaborative AI maintains occlusal contacts, insertion axis, and functional balance in real time, helping you obtain a design that is both functional and easy to manufacture.
