Model Preprocessing
The Model Preprocessing node lets you remove attachments, repair the model, and calibrate the model.
- Views: during preprocessing you can rotate the model by dragging with the mouse, pan by pressing the middle mouse button, and switch views via the view buttons. Auxiliary view tools such as Grid and Occlusal Collision are provided.
Model Preprocessing - Views
- Adjustments: in the top‑right Adjust Model panel you can remove attachments, repair, and calibrate the model.
STEP1 - Remove Attachments: attachment locations are auto-detected, and you may also manually select areas, then click Confirm Remove Attachments.
Model Preprocessing - Remove Attachments
STEP2 - Model Repair: locally raise, lower, fill, smooth, trim, and fill holes on the model.
Model Preprocessing - Repair
STEP3 - Model Calibration: adjust occlusal plane angles and occlusion for the whole arch or mandible only.

Segmentation
The Segmentation node helps you segment teeth and adjust tooth numbers.
- Views: the top-left Tooth Numbers control toggles tooth number display. In segmentation, the top-right Adjust Segmentation offers two adjustment modes: move key points on the gingival line, or reselect teeth by lasso.
Segmentation
Initial Position Model
The Initial Position node helps you adjust tooth axes and landmarks and offers tools such as Crown-Root View, Distance Measurement, Bolton, Crowding, Symmetry, Overbite/Overjet analysis and Bite-jumping editing.
- Provides Root and Gingiva views, plus auxiliary tools for Tooth Axis, Tooth Landmarks, and Adjacent Gaps.
Initial Position - Views

Treatment Plan
The Treatment Plan node contains AI-generated treatment proposals and supports manual edits; changes will affect downstream nodes. It includes Basic Treatment Plan and Expected Treatment Outcome.
- Basic Treatment Plan → Tooth Information: includes Extractions, Locked Teeth, and Reserved Space.
- Basic Treatment Plan → Collision Resolution: includes Release Upper and Interproximal Reduction (IPR).
Treatment Plan - Basic
- Expected Treatment Outcome → Target Position Reference: used to adjust sagittal & vertical target references. The AI tooth-arrangement algorithm aligns the full dentition based on anterior tooth positions.
- Expected Treatment Outcome → Midline Target Position: used to adjust midline reference.
Treatment Plan - Expected Outcome
Final Position
The Final Position node helps you view, analyze, and adjust AI tooth-arrangement results.
- Views: new Occlusal View, Composite View, and Comparison View.
Final Position - Views
- Auxiliary view tools: Grid, Occlusal Collision, Tooth Numbers, Crown-Root View, Superimpose, Arch Curve, IPR, Tooth Landmarks.
Final Position - Auxiliary Tools
- Analysis tools: Distance Measurement, Three Views, Bolton, Crowding, Symmetry, ABO-OGS, Overjet/Overbite, Movement Scale. When viewing Crown-Root View together with Movement Scale, you can inspect root and crown movement separately.
If you modified the model in Model Preprocessing, Segmentation, or Initial Position, please click Reanalyze at the bottom of the page; otherwise the crown-root view will not update automatically.
Final Position - Analysis Tools
- Adjustments: in top-right Adjust Final Position Model, you can move teeth and edit the arch curve.
PART 1 - Tooth Movement:
- Locking teeth: select a tooth and click the lock button to lock it; quick lock options exist for anterior/posterior.
- Movement control: select teeth, choose rotation center (root, crown center, cusp tip, pivot). Drag controls to translate/rotate, or change numbers in the fields. On the left side of the model you may enable "Allow IPR over limit". You can also click the plus on the model to add IPR or reserved space.
Adjust Final Position - Tooth Movement
Configuration: Tooth Adjustment Options can enable auto adjacent teeth movement and arch-curve matching. IPR Configuration controls whether anterior or posterior movement is prioritized when adjusting IPR/space. Mesial/Distal movement along arch curve and Tooth coordinate system options are available — using the final-position tooth coordinate system is recommended for movement calculations.
Adjust Final Position - Configs
PART 2 - Arch Curve: drag anchor points on the arch curve to manually adjust, or use Adjust Arch Shape to set Square-Round, Oval, or Sharp-Round profiles.
Adjust Final Position - Arch Curve
Staging
The Staging node helps you view and edit the AI automatic staging plan. It also provides editors for Bite-jumping, Overcorrection, and Passive Appliances.
- Views: click the play button in the bottom navigation to view the staging animation. You can combine this with Occlusal Collision, Crown-Root View, Superimpose, and other auxiliary tools.
Staging - Views
- Adjustments: two modes.
1.AI Preferences (quick edit, recommended for clinicians): By adjusting the Maximum Correction per Step, you can set the movement threshold for each stage of treatment. Once edited and submitted, the AI algorithm will ensure that tooth movement in the newly generated staging sequence does not exceed this predefined limit.
Staging - AI Preferences
Set the default per-step maximum movement under Profile → Account Settings → Preferences. New cases will apply this default when generating staging.
Preferences - Staging
2. Manual Staging Adjustments (powerful; recommended for technicians): the staging navigation left panel shows movement/rotation types; top-right lets you set the normal treatment maximum steps. Drag keyframes to edit tooth movement steps; select a tooth and edit movement amounts via numeric fields.
Staging - Manual Adjustments
Keyframe Operations
1. Right-click a keyframe to open the context menu and copy or delete the current keyframe.
Keyframe - Copy & Delete
2. Deleting a custom keyframe will undo the corresponding tooth movement; undoing a tooth movement will remove its custom keyframe. Undo shortcut: Ctrl+Z.
Keyframe - Undo
3. Hold Ctrl to multi-select keyframes, or hold Alt to box-select, then drag to move in bulk.
Keyframe - Multi-select & Box-select
4. Right-click empty space to create a new keyframe.
Keyframe - Add
Keyframe Direction Sequences To inspect movement/rotation directions, select the desired direction type on the left. Click a tooth sequence dropdown to show six direction components.
Keyframe - Direction Sequence
Keyframe Sequence Speed To view tooth movement speed at each stage, first click the Reset to Linear Interpolation Plan button on the left. Then hold the Ctrl key and select the keyframes at both ends of the sequence; the system will automatically display the tooth movement speed in six directions within that sequence.
Keyframe - Sequence Speed
Examples
1. Slow down a tooth movement
Example - Slow Tooth Movement
2. Speed up a tooth movement and end earlier
Example - Speed Up Tooth Movement
3. Pause a tooth movement for a few steps then resume
Example - Pause & Resume
Editors:
- Bite-jumping: set the step number for bite-jumping. To use bite-jumping, configure it earlier in Model Preprocessing.
Staging - Bite-jumping
- Overcorrection: add overcorrection steps to the upper/lower arch and edit affected teeth.
Staging - Overcorrection
- Passive Appliances: added passive appliance steps are appended to the final steps and applied to both arches simultaneously. To add during staging or to a single arch, duplicate keyframes in the keyframe sequence list.
Staging - Add Passive Appliance
