TMJ study with dual workflow
Temporomandibular joint (TMJ) studies have specific requirements: they capture closed and open positions, and sometimes lateral movements, in separate acquisitions. CBCTHub has a dedicated TMJ viewer that shows the two volumes side by side with matching orientation.
Upload a TMJ study
- 1Acquire the two captures on the scanner: closed and open.
- 2Upload the first capture as the main exam in CBCTHub (closed, by convention).
- 3On the exam detail, click Add capture. Upload the second (open).
- 4Label each capture accordingly (“Closed”, “Open”).
Dual TMJ viewer
When opening the exam, choose the TMJ view. The viewer splits into two side panels (Right / Left) with synchronized crosshairs.
- Assign captures to sides: there is a selector in the top header. Define which volume (closed/open) goes to the right side and which to the left.
- MIP slab: the sagittal is shown with a 10 mm MIP by default to improve condyle visualization.
- Local Orient and Crop: each side has its own orientation and crop controls to show exactly the condyle area.
- Inverted axial crop: the axial slider is inverted only in TMJ because what matters is the condyle, not the alveolar ridge.
TipIf you only have one capture (single), the TMJ viewer shows only one side without asking for the second volume. If you later want to convert it to dual, add the second capture and reopen the exam.
CasoCondylar movement evaluation
1. Upload closed and open as multiple captures of the same exam.
2. Open the viewer in dual TMJ mode.
3. Assign closed to one side, open to the other.
4. Compare condyle position and shape between both: translation, rotation, asymmetry.
5. Mark areas of interest on each side with arrows. Write the report analyzing both.
