References should be determined after the mandibular movement tracking. Confirming all anatomical landmarks and planes at this stage not only ensures the accuracy of subsequent design steps but also facilitates more precise diagnosis, measurement, and analysis throughout the digital workflow.
Note:
- Resetting a step will reset all subsequent steps.
- If the case contains DICOM data, all references are confirmed based on the DICOM model. Otherwise, intraoral scan and facial models are used.
- DICOM-Based Reference adjustment
- Facial Model-Based Reference adjustment
Anatomical landmarks and planes | DICOM Model | Facial Model | Notes |
Hinge Axis | Condylar points are placed automatically | Manually mark the highest point of the mandibular condyle on both sides | / |
Incisal Point | Automatically marked by default | Click the midline of the mandibular incisor edge | / |
Horizontal Plane | Automatically generated parallel to the hinge axis using 3 points: left infraorbital point, left porion, right porion | Automatically generated parallel to the hinge axis using 3 points: left infraorbital point, left cheek point, right cheek point | Plane translation: Hold and drag the arrows up/down to move vertically Plane skewing: Drag the points up/down to adjust tilt |
Median Sagittal Plane | Automatically generated perpendicular to the horizontal plane using: incisal edge point and midpoint of the hinge axis | Automatically generated perpendicular to the horizontal plane using 4 points: soft tissue nasion, nasal tip, nasal base, upper lip prominence | Plane translation: Drag arrows left/right to move horizontally Plane skewing: Drag points left/right to adjust tilt |
Coronal Plane | Automatically generated based on the horizontal and median sagittal planes | ||
Virtual Articulator Parameters
Once all references are confirmed, the following parameters of the Amann Girrbach Articulator will be automatically calculated and displayed:
- Sagittal Condylar Inclination (Left/Right)
- Lateral Condylar Inclination (Left/Right)
- Immediate Side Shift (Left/Right)
- Lateral Incisal Inclination (Left/Right)
- Sagittal Incisal Inclination
