Fully Edentulous CBCT Scan: Dual Scan Protocol of Maxilla and Mandible

1.  On a dry, well-fitting denture, place 6 x-ray markers:

  • Place 3 markers on the facial/buccal surface and an additional 3 markers on the lingual/palatal surface
  • Place the markers on varying axial planes
  • Example: if you place a marker on the buccal area of #2-3, then place your next marker on the lingual of #4-5, the next marker on the facial of #8-9 area and so on

*Do not place the markers on the intaglio surface of the denture*
