Mandibular Movement
- Record and simulate patients' actual mandibular movement when occlusion is aligned.
- You can make a record of the following movements: Free Movement, Left Lateral Movement, Right Lateral Movement, Protrusive Movement
The mandible and maxilla must be aligned with each other in order to diagnose patients using scan data, establish treatment plans, and fabricate dental prostheses and devices. To demonstrate positional relationships, we assisted our users in aligning the mandibular and maxillary occlusion target data based on the first and second occlusion data. However, it only shows the position of the maxilla and mandible when they are still and not moving.
To create more accurate prostheses and devices, we must consider not only the center occlusion but also the patient's mandibular movement caused by TMJ motions. You can use the "Mandibular Movement" feature to record actual mandibular movements based on maxillary data and use the simulation data for prosthetic manufacturing.

How to Use
1. Acquire maxillary and mandibular data first to enter the Occlusion stage.
2. Acquire the first (and the second) occlusion scan data and proceed with alignment.
3. Click the Mandibular Movement icon at the bottom of the screen when it is activated.
4. Select an icon of desired movement direction at the bottom from Free, Right Lateral, Left Lateral, and Protrusive.
5. Place the scanner tip where the maxillary and mandibular meet while the patient keeps contact between the jaw.
6. The Live View window appears on the screen when the scanner starts recording. Then instruct the patient to move the mandible according to the selected movement direction. Make sure both the mandibular and maxillary teeth appear on the Live View. Scanning will be interrupted if the jaws are too far apart, and the movement is no longer reflected on the screen.
7. The play bar and icons regarding mandibular movement simulation appear on the screen once you finish recording. You can play the movement recording by clicking the "Start" button. You can also adjust the speed of movement or play it repeatedly.
8. Click the "Deviation On/Off" icon to show or hide the interference areas while the mandible is moving. Analysis to represent colors may take some time.
9. Click the "Switch Deviation Display Area" to display the scale for all data or contact areas only.
10. Click the "Switch View Style" to change the view style between "Opened Jaws" and "Closed Jaws."
11. Click "Exit" to return to the "Overview" stage, and the mandibular movement recording will be added to the data tree in Medit Link.
