📖 [Occlusion Analyzer] Modes

Modes in this app are not subject to any specific sequence. You can choose which ones you want to work in depending on your needs.

There are two icons that do not represent an individual mode but rather the beginning and end steps of the overall workflow - Reassign Data and Complete.

Icon	Title	Description
	Reassign Data	Start again from the data assignment. ℹ️ Note Initialize the process by changing what data is assigned as maxilla, mandible, and occlusion.
	Overview Mode	Create section planes and analyze data through section views. ℹ️ Note Overview Mode is entered by default when no other mode is selected.
	Auto Analysis Mode	Review the results of the automatic occlusion analysis.
	Alignment Mode	Manually align the maxilla, mandible, and occlusion data.
	Edit Mode	Edit and trim data using the wide array of functions provided.
	Mandibular Movement Mode	Play the mandibular movement recording.
	Complete	Overwrite or export files to save the changes and close the program. ℹ️ Note Read more about saving data in the “Data Management” chapter.

Overview Mode

In Overview Mode, you can closely examine your imported data and work with the Section View feature, which allows you to conduct a more detailed review of the contact and alignment between the upper and lower digital scan data.

This mode is entered by default when no other mode on the left-side panel is selected.

On the right side of the window, you can find a tools panel that includes all key features needed to perform occlusal analysis. With certain limitations, all of them can be used across all modes.

Tools

Icon	Tool	Description
	Color Map On/Off	Turn on or off the color map.
	Switch Deviation Display Area	Switch deviation display scale between all data and contact area only.
	Switch View	Change the view between opened jaws and closed jaws.
	Section View	Turn on the toggle to utilize tools for section view creation and management.

How to use Color Map

The Color Map is enabled by default and visualizes how the upper and lower digital models contact each other. Refer to the color map legend in the left corner of the window to help you review contact areas and check whether the scanned data are aligned as intended.

Use the icon at the top of the color bar legend to expand it and show specific value ranges for each color.

If you want to see only the contact points data, click "Switch Deviation Display Area" and the color bar will be limited to positive values only.

How to work with section views

Turn on the Section View toggle to work with section planes.

Tools: Section View

Icon	Tool	Description
	Add Section Plane	Add a new section plane.

How to use "Set Arch Line"

To work in the app, the program must be able to detect an arch line on your data. 

If an arch line is not detected upon importing data, you will be asked to set one. It can be also adjusted later.

⚠️ If you're using scan data with only one quadrant of both maxilla and mandible, the app may ask you to set the arch line manually upon entering.

1. Select three points on the data following the curvature of the arch, and an arch line will be created.

• You can delete the last created point to correct the line using the "Delete Marker Point" feature.
• If you're adjusting the existing arch line, you can reset to the last saved one using "Reset."

2. Click "Exit" when done, and the arch line will be saved.

Icon	Tool	Description
	Delete Marker Point	Delete the last created marker point.
	Reset	Restore previously saved arch line.
	Exit	Go back to the previous step.

Auto Analysis Mode

This mode is entered automatically after data assignment. Here you can review the automatically generated color mapping that visualizes how the upper and lower digital models contact and align with each other.

Annotations signify areas with occlusal interferences and report specific values for overlapping amounts.

💡Click the icon at the top of the color bar for a legend with specific value ranges.

1. If you want to examine the reported areas in more detail, click the "Examine Reported Areas" button to see the section views for all detected areas.

2. To make measurements and control view options, utilize tools provided in every section view window. 

Each section plane and its corresponding section view window are marked by the same color.
