Part of the image is enlarged while the other is reduced
The schema described on Figure 22 the image obtained; it is possible
to observe that one part of the radiography is blurred and enlarged,
while the other is reduced and seems to be in focus; the two condylar
rami are at the same height on the X-ray.
Figure 22
Possible cause:
This effect can be due to two different causes.
In the first one, the sagittal medial plane is not aligned
with the relevant centring light beam, which falls at
the centre of the chin support.
In the second case, the centre of the sagittal medial
plane corresponds with the centre of the chin support,
but the patient’s head is rotated.
In both cases, one side is closer to the sensor plane than the other,
thus resulting in a different magnification of the two sides; the part
more distant from the sensor will be more magnified while the part
closer to the sensor plane will result smaller. The result will be an
image as shown in Figure 22; the left-hand area of the image shows a
bigger magnification that can be noticed both on the teeth and on the
ascending rami of the TMJ.
Solution:
Check the positioning of the sagittal medial plane by using the
relevant centring light beam.
Check also the position of the sagittal medial beam; lighted, it must
fall both on the centre of the chin rest and also on the centre of the
bite.
