•
The image shows TMJ at different height
This fact is described in Figure 8-7.
Figure 8-7
Possible cause:
The mid sagittal plane is not vertical.
This can be a patient’s
problem, but if the defect is always present, check the laser beam.
Remedy:
Verify that the laser beam is vertical; this check can be performed
very quickly using the laser beam and verifying that falls on the
center of the chin support; remove the chin support itself and check
that the beam falls on the center of the holes used to fix the chin
itself.
If not, a possible cause can be due to a non perfect horizontality of
the chin arm, that must be adjusted using the relevant screws.
