4. Position the patient with the temple clamps ensuring that the chin rests on the special
support; the hands should rest on the front handles. Ask the patient to bite the reference
notch of the bite with his incisors. In the case of edentulous patients, he/she must rest the
chin against the reference shoulder of the edentulous chin support.
5. Press the "Luminous centring devices" key (2 - Figure 17). Two laser beams will light up the
sagittal medial plane line and the horizontal line. Position the patient's head in such a way
as to ensure that the luminous beams fall in correspondence with respective anatomical
references
6. At this point, the patient has to step forward making sure of keeping his head within the pre-
aligned anatomical references. This ensures a greater extension of the spine in the cervical
area, improving the darkening of the X-ray in the apical area of the incisors, and avoiding the
collision of the tube-head with the patient's shoulders.
7. Close the temple clamps to help the patient maintain a correct position.
Note
The laser centring devices remain on for approximately 2 minute; shutdown can be
anticipated by pressing the "Luminous centring device" key (2 - Figure 17) or, with
alignment complete, by pressing the "Patient entrance" key (6 - Figure 17) to begin
preparation for exposure.
