8) Check the proper positioning of the Frankfurt plane superimposing the
upper horizontal light beam (dotted line). To adjust the patient’s head
inclination, work the column up and down movement buttons. Make sure
that the patient keeps his or her back straight and extended.
9) Ask the patient to smile to uncover the upper teeth. The vertical light beam usually falls between the canine cusp
*.
In case of patient dysmorphia, move the light beam forward or backward towards the canine, by using the
console buttons
, in order to optimise teeth focusing.
* the canine can be used as a useful reference to fine-tune the patient alignment, but this is not strictly necessary.
10) Press the CONFIRM button and, just before leaving the room to press the X-ray emission button, ask the patient
to close his or her eyes, swallow and place the tongue against the palate.
5.4.4. TMJ EXAMINATION
5.4.4.1. LATERAL TMJ
1) Remove the chin rest and the bite, and insert the under-nose support.
2) Adjust the unit height, in order to facilitate the patient’s access, using the keys
to move the column
upward or downward until the under-nose support reaches the height of the nose base. The telescopic column
will move slowly at first, then it will speed up.
TMJ examinations can be carried out with open mouth or closed mouth by selecting the proper icon on the
control console.
3) Guide the patient toward the unit so that he/she faces
the under-nose support and can grab the wide
handles. The patient will rest the nose base on the
under-nose support, as in the figure.
4) Check the symmetry of the patient’s head using the
sagittal vertical trace as a guide; check the correct
positioning of the Frankfurt plane by overlapping the
upper horizontal light trace, as shown in the previous
figure. If required for the examination and if
necessary, slightly tilt the patient’s head forward to
ease the maximum mouth opening.
5) Once the correct orientation has been found, lock the
craniostat as explained in paragraph 5.4.2.
