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*


2.  Pre-Scan Patient Instructions:

  • Use a bite registration for separation, secure fit, and to eliminate rocking
  • Confirm fit by asking the patient “Is the denture fitting correctly?”
  • Breathe through your nose, close your eyes, and place the tongue at the back of the mouth

3.  First Scan: Capture CBCT of ONLY the maxilla denture with x-ray markers.

  • Position appliance on a foam block
  • Orientate teeth occlusal DOWN

CBCT General Settings: 6cm  – 8cm, 0.3 – 0.4 Voxel

4.  Second Scan: Capture CBCT of ONLY the mandible denture with x-ray markers.

  • Position appliance on a foam block
  • Orientate teeth occlusal UP

CBCT General Settings: 6cm – 8cm, 0.3 – .4 Voxel

5.  Third Scan: Capture CBCT of patient WEARING maxilla AND mandible dentures with x-ray markers.

Vital Anatomy to be captured:
