6. Check the patient's occlusal plane C. Adjust the unit height using
the up (A) and down (B) keys.
Ä The occlusal plane is slightly inclined toward the front.
7. Check the position of the patient's spine.
Ä Ensure that the patient's spine is slightly inclined, as shown in
the diagram.
Tip: To achieve the correct positioning of the spine, ask the
patient to take a small step towards the column of the unit. The
patient's cervical vertebrae are thus stretched. This prevents
shadowing of the anterior tooth region on the X-ray.
8. Swivel the control mirror outwards. Press the left recess on the
touchbar D.
Ä You can see the patient in the control mirror.
9. Switch on the light localizer. CAUTION! Risk of dazzle
Ä Two red laser lines reflect on the patient's head. To switch off
the light localizer, press the key again. It switches off
automatically after approx. 100 seconds.
10. Align the patient with the central laser line G.
Ä The laser line reflects in the center of the patient's anterior teeth
or the middle of the face (mid-sagittal).
11. Align the patient's head according to the Frankfurt horizontal plane
E
(E).
Tip: The Frankfurt horizontal is used as a reference plane. It runs
between the upper edge of the ear canal and the deepest point of
the lower eye socket edge.
12. Adjust the height of the light localizer using the slider (F).
Ä The laser line reflects on the upper edge of the outer ear canal.
13. Correct the patient's head inclination as necessary. Briefly press the
up A and down B height adjustment keys.
Ä The laser line reflects on the lowest point of the lower eye
socket edge.
