Precautions before Use
Perform the following activities on your product and accessories before use.
Visually Inspecting the Scanner for Damage
Visually inspect the scanner for damage or signs of deterioration by doing the following:
- Inspect the scanner's Lens Window.
- Inspect around the scanner buttons and contact points.
If damage is noted, do not use the scanner, and contact Dandy.
Visually Inspecting the Scanner Tips
Visually inspect the Scanner Tips for signs of deterioration by doing the following:
- Verify that the Scanner Tip is not damaged, and its components are not detached.
- Verify that the Scanner Tip mirror does not have any smudges or scratches on it.
- If deterioration is noted, replace the Scanner Tip.
WARNING
The scanner's Lens Window is a delicate optical component. When the scanner is not in use, mount the lens window protective cover to protect it from damage and dirt.
The mirror in the Scanner Tip is a delicate optical component. Its clean and undamaged surface is critical to scan quality.
If you see poor scan quality or an unclear video preview in the software, clean the mirror of the Scanner Tip and the Lens Window using a microfiber cleaning swab, applying ethanol that is free of impurities.
Use
Accessing the Software User Interface
To access Chairside, the software user interface, refer to the quick start guide.
Review the Help Center articles for individual workflows and ordering steps.
Preparing the Teeth
- If there is a preparation area, retract the gingiva by gingival restriction cords. And extract the cords just before scanning the preparation.
- Before starting the scan, dry the teeth thoroughly.
- During the scan, re-dry the teeth moderately.
Preparing the Scanner
The Scanner Tip attached to the scanner provides a sanitary shield for patients. Always disinfect the body of the scanner and perform sterilization on the Scanner Tip after each use.
CAUTION: Scanner Tips received from the manufacturer are NOT sterilized. You must sterilize them before the first use.
CAUTION: Avoid any liquid from leaking into the air outlet near the Lens Window or the air inlet at the rear of the scanner (see the figure below); otherwise, the scanner may be damaged.
To prepare the scanner, follow these steps:
- Make sure the Lens Window at the tip of the scanner is clean by wiping it with a moist, lint-free cloth or lens tissue.
- Slide the Scanner Tip onto the scanner as shown below.
- The 2 rectangles (indicated by a red circle) are the tip detection sensor. See the troubleshooting section for more information if malfunctioning.
-
Scanning
- To start scanning, place the Scanner Tip on the surface of the tooth to stabilize the scanner and press the Scan button. Wait until a 3D model appears on the 3D model display screen, and then slowly move it along the arch at 0-5mm from the teeth
- The recommended scanning protocol consists of 3 sweeps: occlusal, lingual, and buccal to ensure good data coverage of all surfaces.
- It is recommended that you start the first sweep from the occlusal surface, with the first molar.
- The second sweep can scan both the lingual and buccal sides
- The third scan covers the opposite side of the second sweep.
Troubleshooting
| Problem Description | Action |
| No connection between the scanner and the computer. | Detach the USB Type-C Connector from the Handpiece, and insert it again. If the problem is not solved, contact Dandy. |
| The 3D model shows discrepancies and overlapping areas. | Perform the scan using the suggested scanning method. Use the Cut tool to eliminate mismatched data and excess tissue, then conduct a rescan. |
| A decline in precision or poorly stitched images may be noticed during acquisition. | Clean the lens window at the scanner's base using a moist, lint-free cloth or lens tissue to remove dust or water stains. Ensure the Scanner Tip is securely attached, and check that the preview video does not have dark edges or other dirt. |
| The Scanner Tip is installed but not detected. No live video is displayed. | After removing the scanner tip, wipe the Scanner Tip Detection Sensor to ensure it is free from dirt or debris. Reattach the Scanner Tip and verify that it is securely and firmly connected to the scanner. |
| The inner surface of the scanner's lens window at its base shows signs of fogging. | Attach a fully dry Scanner Tip to the scanner, place the scanner in the Holder or desk, and wait for the fogging to clear. If the fogging persists after 24 hours, contact Dandy for help. Ensure the Scanner Tip is completely dry before attaching it, and avoid using disinfectant-soaked cloths to clean the scanner. |
| After stopping scanning, the scanner is disconnected and cannot be automatically reconnected. |
Try the following steps in order. Check if the scanner is turned off. Press any button on the scanner or take it out of the holder to turn on the scanner again. The scanner startup process may take several seconds. Disconnect the USB connector of the scanner from the computer, and then reconnect it to the computer. The scanner will automatically power on and connect. |
