Ortho-phthalaldehyde (OPA)
Disinfection cabinet (high temperature and high pressure)
Scan tip sterilization for intraoral scanners under a high temperature and high pressure:
Please follow the instructions given below to ensure normal functionality of the intraoral scanner.
Sterilization Procedure:
1. Soak the scan tip in OPA. Then gently clean the scanning head to avoid residue of disinfectant and make sure the optic is clean.
2. CaviWipes can be used for sterilization for 2-5 minutes. Sprays are optional.
3. Put the dry and clean scan tip in a sterilized vacuum bag for sterilization.（ The scanner tip must be completely dry.）
4. Sterilization at 121℃ and 1.5 atm for at least 15 minutes is suggested. The sterilization process must be completed under a vacuum environment and gauze should be used to fill in the scan tip.
Notes:
1. Daily-use tissues are not recommended due to residue left behind is hard to clean.
2. After cleaning, wipe the scan tip. Optic must be clean and dry.
Reason: If we insert the entire tip into the liquid, immersing it, as written in the guide, but the result is an oxidation of the contacts on the scanner because the disinfectant liquid remains inside the TIP even if autoclaved, the bag keeps all the humidity inside and the result is that the contacts on the scanner then oxidize because they are moistened.
