MentronTrack supports to compare models to verify the orthodontic results. Detailed data and intuitive comparison tools bring clear and specific evidence for juding the result and reviewing treatment plans. 

STEP 1: Model Comparison

Click the “model comparison” to enter the interface and models will be aligned automatically. The alignment is in accordance with the max coverage rate. 

If necessary, you can drag the points to align models manually, and click the “alignment” button to finish. Switch the maxilla and mandible in the upper right corner. Then, you can compare models through modules on the right side. 

Tips: Manual alignment

Press the points and drag them once they turn from green to red. 

Additionally, the program enables users to align models with 8 points. You can click anywhere on the models to create a new point for alignment. Because orthodontic treatments can cause obvious changes in teeth, pick points at places with no or less movement. 

STEP 2: Tooth Movement Analysis

Users can check the results of tooth movement analysis. Models compared are presented in white and blue color to describe differences more intuitively with turning off texture.

Switch the maxilla and the mandible by clicking the icon in the upper right corner. 

Users can select the specific tooth to highlight the corresponding result line in the measurement table, and also select the specific result to highlight the corresponding teeth position and show the direction. 

STEP 3: Ribbon

The ribbon shows the difference between the two models. 

Users can select the comparison area at the bottom of the interface. The “tooth” area only contains teeth, and the “jaw” area encompasses the entire model, including the gingiva, empowering users to check the changes.

Users can click on any point on the surface to obtain a point-specific distance measurement.

Users can also adjust the threshold on the bar. 

A photoscope is provided for zooming in. Drag the photoscope to observe models detailedly.

STEP 4: Section

A section is generated, showing a cross section of 2 overlaid models. Users can adjust the section by dragging the 2 black points, then, dragging the blue point to move the section on the arch line.

Users can select the comparison area at the bottom of the interface. The “tooth” area only contains teeth, and the “jaw” area encompasses the entire model, including the gingiva, empowering users to check the changes.

The resulting cross section appears, by default, on the cross section sub-window. To make a measurement, pick any 2 points on the cross sections’ outlines and a black line will appear alongside a linear distance measurement. The “zoom in” button and the “zoom out” button help users enlarge or narrow the sub-window. The “reset” button can clear all operations.
