Precautions and Maintenance Guidelines for Dental Scanners

Ⅰ Getting ready to use a dental scanner

Checking equipment and meeting environmental requirements
A basic check should be done on the dental scanner before each use:
Make sure that the lens and scanning head are not cracked or loose.
A stable connection between the cable interface or wireless module
The software version is either the newest one or has passed stability testing.
If the equipment has to be calibrated regularly, the calibration status is normal.
Environmental needs are just as important:
Stay away from places that are harsh or reflecting.
Make sure the area where you scan is clean and dry.
The temperature and humidity inside should be within the equipment's suggested range.
Getting the patient ready for an intraoral scan
For intraoral scanners, how well you prepare the patient has a direct effect on the quality of the scan:
Take away blood, saliva, or other debris from the surface of teeth.
Use a suction pipette correctly and keep the area you're scanning dry.
Anti-reflective spray can be used on places that reflect a lot of light, such metal restorations.
Tell the patient how the scanning process works so they don't move suddenly.
If patients cooperate, it can make scanning much more efficient and cut down on the number of scans that need to be done again.

Ⅱ Things to keep in mind when using dental scanners
The right order and path for scanning
One of the most prevalent problems for beginners is an unreasonable scanning path:
It is best to scan slowly from the occlusal surface to the lingual side to the buccal side.
Keep the scanner head moving gradually and don't let it hop around quickly.
Make sure the software gives you real-time prompts to cover all areas.
Errors in data stitching might happen simply when you often stop or skip scanning.
Set the distance and angle of the scan
Keep the scanning head at the right distance from the teeth, which is normally between 5 and 15 mm.
Don't get too close and lose attention, or too far away and miss info.
To get clean edge lines, change the angle of the scan as needed.
To get good edge data, you need to keep the angles and distances stable.
Don't fall for frequent operational mistakes
 

Ⅲ Important things to remember when using different kinds of dental scanners

Scanner for the mouth
Be aware of how hot the scanner head is and don't use it for long periods of time.
You need to change the scanning sleeve or protective cover often.
Follow the steps for disinfection and sterilisation exactly.
Don't let the scanner head hit teeth or other hard things.
Scanner for the lab
The model has to be totally dry.
Don't let bubbles or damage happen on the surface of gypsum.
The positioning should be sturdy so that it doesn't shift while scanning.
Clean the dust out of the scanning chamber on a regular basis.

Ⅳ Standards for cleaning and disinfecting dental scanners
Intraoral scanners must be disinfected.
Oral scanners are medical contact devices, and they must be cleaned according to industry standards:
Use the disinfectant that the manufacturer suggests.
Do not use high temperature and high pressure sterilisation unless the equipment specifically says it may.
Use disposable scanning headwear to stop the spread of germs.
Let the air dry naturally after cleaning to avoid leaving behind fluids.
How to clean lenses and scanner heads
Use fabric that doesn't leave lint or special lens paper.
Don't let anybody use any solvents that are not alcohol.
Wipe gently to keep from scratching the lens.
Lens damage is the most common hidden threat that people don't think about, and it can directly effect how accurate scanning is.

Ⅴ A guide to daily care and maintenance for dental scanners
Regular software updates and calibrations
Set the calibration according to the manufacturer's cycle.
To keep calibration plates clean, they need to be stored correctly.
Update software versions on a regular basis
Make a backup of scanned data to keep it safe.
Important things to remember about hardware maintenance
Keep equipment from falling or shaking too much.
When you're not using it, put it in a special bracket.
Do not bend or pull on cables.
To avoid overcharging, wireless gadgets need to be charged in a certain way.
Long-term storage tips for things you don't use
If you don't use the scanner for a while:
Clean and dry completely
Put in a place where dust and moisture can't get in
Check the power every one to two months.
