Model Comparison¶

Model Comparison is a tool that can compare and analyze the differences in a patient's intraoral data at different times. It can monitor multiple sets of tooth position changes and intraoral tooth wear data for orthodontic treatment.

Click to enter the model comparison interface.

Model alignment¶

The models from different treatment periods are aligned according to the feature points, both automatically and manually.

Click and at the upper right corner of the interface to select the jaw-plane view of the upper/lower jaw.

Note

In the model comparison interface, the upper jaws or the lower jaws will be automatically aligned and displayed by default.

Manual Alignment

Click on the model to add a new point. You can press the point to move it.
After adding corresponding points at the same position of the two models, click to manually align the two models. The overlay effect of two models will be displayed.

Click to reset the positions if needed, leaving only the default three points remaining.

Teeth movement analysis¶

Click to enter Teeth movement analysis. Overlaid effect of the two models and the mobility scale table is displayed.

When you select one tooth on the model, the corresponding data on the mobility scale table will be highlighted.

When you select a specific measurement value on the mobility scale table, the corresponding tooth and its movement reference line will be highlighted.

Note

The movement value of new teeth and dental implants cannot be measured.

Color map¶

Click to view the color map for teeth comparison. You can switch the comparison area: Tooth, Jaw or Gingiva.
Drag the slider at the right bottom corner to set the range.
Note
- The movement variables of the teeth in the new data are compared with the scanned data from earlier times.
- Positive values are set to red, which indicate a shift toward the cheek; negative values are set to blue, which indicate a shift toward tongue.
- The function of ribbon chart and sectional view cannot be enabled at the same time.
Click on the model and its numerical value will be shown in detail.
The photoscope can be dragged to the model for viewing. Left-click the photoscope to display the magnification effect of Model 2. Otherwise, the photoscope will display the magnification effect of Model 1.

Note

Colors in the photoscope indicate the differences between Model 1 and Model 2 in this target area. The darker the color, the greater the difference.

Sectional view¶

Click Sectional View and a screenshot plane will be automatically created on the model.

The 2D window at the lower right corner shows the corresponding intersecting parts between the plane and the model.

You can switch the comparison area: Tooth, Jaw or Gingiva.

Plane operation	Description
Move the plane	Press the ball in the middle of the plane and move the cursor.
Rotate the plane	Press any part of the plane except the ball and move the cursor.

2D Window operation	Description
Vertical to dental arch	Click to show the dental arch on the model. When moving the plane, it will be vertical to the dental arch.
Draw a section	Click to draw a section on the model. Press and hold the left mouse button, then drag to draw a line to generate a section.
Reset	Click to reset the plane to the original state.
Zoom in/out	Scroll up and down the wheel to zoom in and out the sectional view. Click to zoom in and zoom out the 2D window.
Measurement	Add a point: Click on the line to add a point. Move the point: Press the point and drag. Distance measurement: When 2 points are added, the distance between them is shown on the 2D window. And a line linking the 2 points will be shown on the 3D model as well. Re-measurement: Add another 2 points to measure the distance again.
