– 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:

– Superior: Mid sinus / below orbit

– Inferior: Chin and entire mandible

CBCT General Settings: Full 13cm – 20cm, 0.3 – 0.4 Voxel

6. When scanning a patient following Dual Scan Protocol:

– Review the scan carefully to ensure there is no “Black Air Space” between the denture and the soft tissue of the patient
