Advance 4.0
Incorrect placement – incisal (fig. 16):
Probe tip must be a minimum of 2 mm
from the incisal edge.
Incorrect placement – cervical (fig. 17):
Probe tip too close to gingival tissue.
Maintain a minimum distance of 2 mm to the tissue margin.
If the probe tip is moved off of the tooth prior
to the instrument sounding a "beep", an error message
or an erroneous measurement will be displayed
and the measurement will need to be repeated.
Note:
Prior to measuring a tooth, an infection control shield
must be applied to the VITA Easyshade Advance 4.0 probe tip
and the instrument calibrated. It is recommended to remove
any stains from the surface of a tooth prior to measurement.
It may be required to wipe the tooth with gauze to prevent
the tip from sliding. The probe tip must be placed entirely on
the natural tooth. Any contact with existing restorations must
be avoided. Underlying restorations may adversely affect
the measurement result.
