6.10 Research and correction of possible defects in
dental radiographies
6.10.1 Faults due to a wrong positioning of the patient
Problem Description Solution
Too large and blurred
incisors.
Too small and blurred
incisors.
Radiography with
blank central area.
Asymmetric dental
arch.
Upper apical area too
dark.
Upper central apical
area out of focus.
The image is slanted in
comparison with the
longitudinal axis of the
film and some
anatomical structures
are not symmetric.
The teeth on one side
are bigger than those
on the other side.
CEPH exam: white
area in the lower part
of the film.
The patient is not positioned
correctly, too far from the
optimal focal plane.
The patient is not positioned
correctly, he is too much
beyond the optimal focal
plane.
The spine of the patient
inhibits the passage of the
X-ray since it’s too
compressed.
The mid-sagittal line does
not correspond to the laser
centring beam.
The patient does not keep
his lips shut and the tongue
is not against the palate.
The patient keeps his head
rotated backwards
(Frankfurt plane not
aligned).
The patient head is slanted
(not vertical).
The head of the patient is
rotated with respect to the
axis of the bite.
Panoramic chin-rest still
mounted.
Position the patient correctly, check
that he holds the bite with the
incisors on the fit notch and that the
bite holder rod is vertical.
Position the patient correctly, check
that he holds the bite with the
incisors on the fit notch and that the
bite holder rod is vertical.
Check the alignment of the
Frankfurt plane, try to stretch the
cervical part of the spine moving the
feet of the patient forward (see 6.4.3
points 3/4/6/7) and eventually
correct the height of the chin
support.
Re-align the patient (see 6.4.3
point 6).
See paragraph 6.4.3 point 8.
Position the patient again and realign
the Frankfurt plane.
Position the patient again, correcting
the position of the sagittal plane.
Position the patient again correcting
the position of the sagittal plane and
controlling that the head does not
rotate.
Perform the exam again removing
the PAN chin-rest.
