Analysis of 3D models

Analysis of 3D models

To create a new 3D model analysis, after uploading the models to the gallery, open the Model analysis tab, and then click the New model analysis button. Then select 3D models analysis from the drop-down list.

In the next window, select the model of the mandible from the models added:

After confirmation, the 3D analysis window will open – it is divided into five parts:

  • visualization of currently entered points on an artificial model (top left)
  • parameters of the currently entered tooth width (left in the middle)
  • view and tool settings (left bottom)
  • list of all points with information on whether they were entered (in the middle)
  • work area with the 3D model displayed

There are several ways to start entering points:

  1. Clicking the Start Input button
  2. Clicking on the first point in the middle list
  3. Clicking on the Next Point button
  4. Clicking on the model on the right
  5. Clicking on the appropriate tooth on the model visualization on the left

You can switch between points by clicking the Previous point / Next point buttons, selecting the appropriate point from the list in the middle or by visualizing the model, or by pressing the [Q] / [E] buttons on the keyboard.

After entering a pair of points of the width of the teeth, they will be connected by a line, and on their edges, discs parallel to each other will appear:

To change the position of the active point (highlighted in yellow), simply drag it to a new location or click to indicate the new location. The second point can also be marked by clicking directly on the small red ball that represents it.

If the axis of the currently inserted tooth is different from the axis determined by the width points, on the bar on the right, with the mouse cursor over the oval representing the tooth, turn the middle wheel of the mouse.


In this panel, we can also mark extraction (No tooth), as well as read distances between points projected on a plane (on a pink background) and real (on a gray background). These data also appear in the upper right corner of the window.

The Distally / Mesial fields determine whether the selected point is currently a distal or mesial point. Switching them will change the point selection.


After entering all points from the list, the program will ask if we want to switch to the next model:

The process of entering points is analogous.

After entering all the points, confirm the analysis by clicking Save

Analysis results

In the model analysis window, we see all the measurements made, calculated analysis parameters (in the middle), as well as visualizations of the models with marked distance lines (on the right):

At the bottom of the window there are text fields with measurement values. The fields from the tooth width are duplicated – they have values ​​entered for real and projected distances, respectively.

By default, projected distances are taken for analysis. In case you want to download another value for analysis, right-click on the text frame with the silver frame and select Use this measurement in the analysis.


Changing all parameters simultaneously to real / projected is possible after clicking the button on the left of the screen: All real distances and All projected distances.

If you want to overwrite the analysis value (e.g. measured manually), enter it in the Real distance field.

To restore the original values ​​from the analysis, use the Restore measurements from analysis button.

Text frame markings

Depending on the border of the text frame, it has a different meaning (from the left):


  • measurement in the analysis based on the projected / actual distance (depending on the jaw / mandible – see marking on the left)
  • j / w
  • extraction (no tooth)
  • value entered manually
