                    Sending Great Lakes your scans:

  • Once you have connected with us as a Favorite Lab, you are ready to scan your patient

    • Before you begin scanning, it is important to make sure your settings are where you need them to be

      • Go to "Configurations"


      • Select "Settings"


      • Select "Seat Position" 

        • You need to tell the software where you actually physically scan the patient from because it affects the orientation of the camera

          • For example, most Doctors will scan the upper arch from behind the patient in the 12 o'clock position and scan the lower arch from in front of the patient

            Seat Position

  • Log in and "Create Patient"

    Create Patient

  • Fill out the Patient's Last Name and First Name 

    Patient's name

  • Select "Create Scan"

    Create Scan

  • You are now ready to scan with guidance


  • You will need to scan the upper, lower and bite position. 

    • You will need to provide a vertical dimension of occlusion (VDO) appropriate for the appliance you need.

    • 1.5mm from the highest point of contact for a splint, or open and advanced for sleep or functional appliances


  • Green dots are starting points

    • Position over the molar and wait for three beeps to indicate you should begin your scan

    • Follow the yellow line

      • If you "fall off" you will be given a green point to start again

    • Once you get to the checkered flag, hold your position until you hear three beeps indicating you are done with that scan

    • Follow the prompts to move forward to the next scan

      Scan Images

    •  "Complete Jaw" will show you (in yellow) areas that need to be filled-in

      Complete Jaw


  • Once you're done scanning, you will go through the "Model Phase"

  • "Set Model Axis" should not need to be adjusted because of the guided scan, but verify that it is correct

    Set Model Axis

  • "Check Bite" to make sure the double buccal bite has articulated your models correctly

    Check Bite

  • Digital Bite:
    • Scan the patient’s upper and lower arch, we will only print what we need for fabrication but use the occlusion in many cases to evaluate the appliance design.  For the bite, scan this in the ‘fabrication position’ which should be set up prior to scanning as you would have when taking a wax bite to send to us with casts.  Please be sure to remove any wax or bite material from the buccal surface of the teeth to be scanned so the surface of the teeth can be read by the scanner and orient the upper and lower arches correctly.  Follow the appropriate position recommendations required for the appliance you are requesting.  We will print that bite position and use this to mount the printed models.
      • Examples: 
        • For a Splint:
          • VDO minimum set at 1.5 mm from highest point of contact
        • For a Sleep appliance:
          • VDO open and advanced for the appliance you are ordering
  • "Edit Lower" and "Edit Upper" are for you to cut/trim any areas you do not think are necessary 

  • At this stage, again keep in mind, Great Lakes needs 1.5mm from highest point of contact for a splint or open, and advanced for sleep or functional appliances

    Edit Upper
