Any deposits such as dental cement, composite, polishing paste or
similar must be removed immediately after examination of the patient,
e.g with a swab, before it hardens.
Instruments with particularly complex functional ends or very
stubborn deposits may require ultrasonic pre-treatment.
To avoid injury from double-ended instruments or upright
instruments with upward-facing probes, the washer-disinfector
should be loaded from rear to front, and unloaded from front to
rear.
After thermal disinfection, manual secondary cleaning can be
undertaken according to relevant bio-substance regulations without
danger of infection, although the process must be monitored as
necessary.
Transmission instruments
Turbines,
handpieces and
contra-angles
Transmission instruments with light guide rods can be regarded as
durable, whereas fiber optic bundles can be susceptible to more
rapid wear.
For cleaning, use a neutral to mild alkaline liquid detergent. If deposits
occur a neutralizer based on citric acid should be dispensed.
To avoid clogging of the fine channels in the transmission instruments
by treatment residues from the wash water, the wash water must be
filtered prior to the use for internal cleaning. Therefore, to reprocess
transmission instruments, use the upper injector basket A 105/1 in
combination with the reusable filter tube A 800 and the receptacle for
transmission instruments
A 803 or the holder AUF 1.
The upper injector basket, the filter tube and the holder AUF 1 come
with their own manuals.
After reprocessing, the insides of the handpieces must be dried
with sterile compressed air before being cleaned and sterilized as
appropriate in accordance with the manufacturer’s instructions.
Please observe national regulations.
Before using handpieces again following reprocessing, a function
check must be carried out, e.g., by spraying into a basin, to ensure
they are clear.
