Dry heat sterilization of the prismatic tube without sapphire glass
NOTE
Dry heat sterilization and high-level disinfection must not be
combined.
The process for dry heat sterilization is as follows:
1.
Remove the CEREC camera support (if present).
2.
Pre-cleaning (see „Pre-cleaning of the prismatic tube [→ 54]“).
3.
Remove the prismatic tube from the CEREC Bluecam (see
“Removing the prismatic tube [→ 53]”).
4.
Sterilize the prismatic tube using dry heat at 160°C for 120 minutes
(wrapped or unwrapped) or 60 minutes (wrapped or unwrapped).
The CPAC Sterident Model 200 and the CPAC SteriSURE have
been validated by Sirona Dental Systems.
For 120 minutes 160°C the CPAC Sterident Model 200 is to be
used.
For 60 minutes 160°C the CPAC SteriSURE is to be used.
Use only pouches which are suitable for dry heat sterilization cycle
of at least 160 ⁰ C, 120 minutes.
5.
Store the prismatic tube in such a way that it is protected from
contamination until the next use.
6.
Carefully re-attach the prismatic tube and allow it to lock in place.
See section “Refitting the prismatic tube [→ 53]”.
NOTE
The prismatic tube changes its color which will not have any negative
impact upon the prismatic tube´s durability.
8.1.5.2
CEREC Bluecam with sapphire glass
8.1.5.2.1
General information
The CEREC Bluecam is a very sensitive optical device and must
therefore be handled with the utmost care. Protect the front lens and the
prism against scratching and clean them with a clean lint-free cloth and
ethanol (commercially available cleaning alcohol) whenever a film is
noticed during imaging.
Dental health care providers are advised to select the reprocessing
method that aligns with their infection control process. An effective
infection control program is practical, reasonable, and reproducible.
One method has been validated to reprocess the CEREC Bluecam with
sapphire glass between patient care:
● High-level disinfection of the prismatic tube with sapphire glass
[→ 61]
This method is strongly recommended to be used for the reprocessing
of the prismatic tube with sapphire glass.
