CAUTION
Hot surface!
The coated sapphire glass of the scanner, is preheated in the scanner
cradle. When removing the scanner from its holder, the surface
temperature of the mirror sleeve can be up to 51°C. This may cause
an unpleasant heat sensation on contact with a person's skin or
mucous membrane. These temperatures will not damage the skin or
mucosal membrane. The temperature sensitivity in the mouth is
considerably lower than it is on other surfaces of the skin. The
scanner does not produce any pressure on the mucosa of the mouth.
Temperatures up to 51°C must therefore be classified as being non-
critical for the patient.
After removing the scanner from the scanner cradle, the temperature
of the mirror sleeve drops within a few minutes (< 5 minutes) to less
than 43°C. The scanner is therefore suitable for use in the patient's
mouth for an unlimited period of time.
At an ambient temperature from 30°C, only select the three lower
heater settings.
NOTE
Image brightness
The image brightness during the acquisition is controlled
automatically, so that there is always optimum image brightness,
largely independent of the distance between the scanner and the
tooth.
The surroundings of the tooth to be scanned should be as weakly
illuminated as possible. Avoid any type of external light. Switch off the
operating light.
IMPORTANT
Do not use cotton rolls in the scan area
Do not use any cotton rolls in the vicinity of the scan area, as they can
reduce the precision of the scan and create image interference.
CAUTION
Prevent cross-contamination
Germs can be transmitted to uncontaminated persons via the hands,
materials or objects.
➢ For hygiene reasons, wear a new set of disposable gloves for
each patient while using the scanner.
CAUTION
In the case of patients with allergies to nickel
Should the scanner mirror sleeve make contact with the skin of
patients allergic to nickel, allergic reactions may occur.
➢ Ensure that in the case of patients with nickel allergies, the parts
of the mirror sleeve which may make contact are protected from
areas of skin.
