Biting position with
the chin rest
mm
Ask the patient to step forward, grasp the patient han-
dles, stretch up and place their chin on the chin rest.
Slide the bite piece up or down until the patient is able
to bite it. The incisal edges of the maxillary and man-
dibular teeth must be in the groove in the bite piece.
When you are using the chin support, position the
patient so that the chin, just below the lower lip,
touches the top bar of the chin support.
Press the temple support key to close the temple sup-
ports.
Stand behind the patient and make sure that the
patient's shoulders are level and the neck muscles
relaxed.
Press either of the focal trough positioning keys to
switch the three patient positioning lights on. Note that
the lights will automatically switch off after 25 seconds
if you do not use these keys to adjust the position of
the patient positioning mechanism. If the lights go out
before you have positioned the patient press either key
a second time to switch the lights on again.
Position the patient's head so that the midsagittal plane
coincides with the midsagittal plane light beam. Make
sure that the patient is looking straight ahead as the
light may appear to be correctly positioned but the
patient's head could be turned slightly to one side.
