Warning
Concerning hand hygiene and personnel safety when performing a scan, you must wear
clean surgical gloves through the whole process.
Intraoral Environment
⚫
Make sure there is no foreign body or blood in the mouth after gargling. Stop the
bleeding if necessary.
⚫
If necessary, ask the patient to keep the tongue still and move it to the other side of the
mouth.
⚫
Consider using a dental three-way syringe to blow dry or a tampon to dry the tooth
surface before starting the scan.
⚫
Turn off the oral light on the dental chair and start scanning.
⚫
Consider using aspirators and tampons to keep the surfaces dry during scanning.
⚫
If necessary, consider using an oral mirror to help create space while working in the
narrow area between the teeth.
Scanner Preparation
⚫
Ensure that the scanner head, scanner body, and pedestal are properly pre-cleaned,
disinfected, or sterilized. See Pre- cleaning, disinfection, and sterilization on chapter 10.
⚫
Ensure that the scanner head has no scratches or is not damaged. Additionally, the head
is firmly attached to the front end of the scanner body.
⚫
Ensure that the scanner connection is ready; it is correctly connected to a power source
and powered on, and IntraoralScan is launched and ready to work.
⚫
To avoid condensation on the mirror of the head when scanning, the scanner head must
have been warmed up. For details, see Heating the scanner head on chapter 5.
⚫
Calibrate the scanner and verify the accuracy of the acquisition regularly. For details, see
Calibrating the scanner on chapter 4.
