OVO3 | Positionning of the patient and material

Follow these guidelines to ensure a high quality scan.

Operatory Layout

Make sure the patient, scanner and computer are ideally placed, so that the patient is comfortable, the screen clearly visible and the keyboard or touch-screen accessible while scanning.

Practice proper isolation

  • Use air to keep preps dry
  • Use hemostatic agents - retraction paste, impregnated cord, etc.
  • Use the double-cord technique

Watch the tutorial

Avoid moving tissue: retract lips, cheeks & tongue.

 

Scan Live View

While scanning, the Live View window in the lower left of the screen displays what the 3DISC Scanner is actually seeing. The digital 3D model is displayed in the middle of the screen.

  • If the scanner loses connection with the reconstructed image, the Live View perimeter frame will be displayed in red: return the scanner tip to an already scanned section to resume the scan.
  • If "Use Sound Guidance" is enabled in "Sound Settings", the system will indicate an interrupted scan by going silent.

You can select Live View options in the 3D Settings Menu.

Navigating between workflow steps

For ease-of-use, you can navigate between Scan Workflow steps using the up - down keys on your keyboard.

 

Using the ON/OFF button on the handpiece, you can pause the scanner at any time during the scanning process without leaving the scan workflow.

IMPORTANT - maintain scanning distance

Keep close to teeth (recommended distance from tip to tooth is 0-12 mm)

Scan Memory Use

Over-scanning may use up available memory space. When the warning “Scan memory is running low please conclude scan” is displayed on the screen, no more High Resolution frames will be added to the scan after this point.

If the result is unsatisfactory, It is recommended you delete and redo the scan.

 

Troubleshoot 

 

Make sure that: 

  • The computer on which the 3DiscClinic™ software is installed is connected to an External Power Source.
  • Your 3Disc™ scanner is correctly connected to the computer via the USB - C cable and the USB - C port of the computer meets the system requirements.
  • If using a laptop computer, make sure the power supply is connected to a power outlet and not running on battery power.
  • On laptop computers, battery settings in Windows should be configured to high performance mode only, with no battery saving option (Settings/System/Battery).
