Obtaining an Intraoral Scan

1.  Select New Patient enter all patient info, then either save (for later) or begin a new scan

2.  You will then be prompted to select a lab

3.  Select a delivery date and time 

4.  Select intraoral camera, on right-hand column of the screen

5.  Select the scanner icon on the top middle panel of the screen

6.  Pick up the scanner to take a 2-3 photos of the patient by tapping the button on the handle (tap once to turn on, once to take a photo)

   • For best use, hold the scanner in your dominant hand hand, while using your off hand, thumb resting on the mandible as your fulcrum point and first finger for retracting the cheek

   • The closer the camera is to the dentition, the more clear the photo/video will be

7.  To send the scan, select Comments and Attachments on the right hand of the screen

8.  Under lab notes, enter department (Implant Center, OMFS, Periodontics, UDHS etc) in order for the case to be billed and processed to the correct department.

Tips for Capture Success

• Maxillary scan path:  Capture must be Occlusal, Buccal, Lingual

• Mandibular scan path:  Capture must be Occlusal, Lingual, Buccal

• Reduce overhead lights (loupes light, etc.)

• Where the light is shining is where you are going to acquire an image

• “Fogging” or greying of the scan screen means that you are too far from the surface that you are trying to acquire and are out of view (which at times might be acceptable if this is the palate, for example)

• Handle should turn 180 degrees when passing the midline during buccal scan; if you reach an error point and the scanner does not recognize this change, you can go back to the occlusal plane in the posterior region to center on an area that has been previously recognized

• Ideally entire scan should be <1:30 min and <700 images

• Information that is determined to be excess (ex. Tongue, finger) can be trimmed

  • The brush tool removes only on the surface that you are working on

    • 4 mm brush tool can be used to remove the occlusal surface of the healing abutment, eg

  • The Laser tool removes in all dimensions

  • Information that is missing can be “patched”

    • Blank areas represent areas that did not stitch together well

      • You can address this by trimming off with the brush tool

      • You can then fill in missing information

      • Green pixelation represents areas that have been filled in by the program (rather than a true image from the patient)

    • Shade selection can also occur during this time

      • Trios uses Vita 3D and Vita Classic shades

      • Select tooth with the blue overlay on the right side of the screen

      • Blue pixelation will appear on your scan - this represents areas in which the shade has not been obtained (if none of these spots show up, then you got a perfect scan and it was all captured the first time)

      • Turn your scanner back on to fill in the blue areas for shade selection

    • If you want to see the shade selection, select Shade under the Analysis tab

    • When obtaining the occlusal scan, it is split into two scans by laterality

      • Make small “w” movements while acquiring the data from the buccal aspect of the bite, working from posterior to anterior

      • The software will chime when you have acquired enough data

    • Then obtain a Patient Motion Bite

      • This records points of contact during occlusion

      • The box must be green while obtaining info If there is fogging from the patient’s mouth being too warm, have them swish with cool water

  To finalize the can, select Next and it will complete post-processing.  Post-processing will take a few minutes.

  • To make sure you have all the information you need, use the icons along the bottom

    • Direction examines the path of insertion, undercuts, etc

    • Clearance shows interocclusal space for restorations

      • The toggle under your patient’s name allows you to switch between arches

    • Annotations will allow you to communicate specific instructions to the lab (ie - the patient wants to keep their diastema)

    • Shade Measure > Tools > Snapshot will send a photo to the lab for an easy reference for the lab to reference the shade

    • Motion shows contacts, lateral excursion through a short video

Send a Scan to the Lab

1. Select the blue and orange people

2. Then select send

3. If you included your patient’s email address, then they will receive an email to view their scan on 3D’s platform

4. Once you see the resend option, you know that the file has been shared with the lab

5. To send to an additional lab, or make an alternative plan: Right click on the plan under the patient’s chart
