  • 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.
