7. Instruct the patient to swallow and keep the tongue against the palate. Patient's tongue must
be held closely to the roof of the mouth during the exposure, otherwise a dark air space
between the dorsum of the tongue and the palate could obscure the apical region of the
maxillary teeth.
8. Patient must stay motionless during the examination.
The result of all the above listed actions will be a radiography where all the parts are properly
exposed and are well identifiable as shown in Figure 36.
Figure 36
In a good panoramic image, all anatomic structures are well represented and an equal
magnification and sharpness of all structures can be seen.
The image must be symmetric, with the ascending rami of the temporo mandibular joints almost
parallel and showing posterior vertical borders. The occlusal plane is quite smiling, despite this
the palatal plane does not overlap the apex of the upper arch and therefore allows a good view
of the apex itself. The spine is well compensated.
Note
The region of the incisors is the most critical because the anterior portion of the image
layer is very narrow. Points 3 and 4 are determining for a good result.
Note
Any flaring of dentition may not allow crowns and apices of both arches to fit in the
image layer at the same time. For these patients, you must purposely move him/her
further forward in order to move the apices into the image layer.
