Fully Edentulous CBCT Workflow

The following workflow is for capturing a CBCT on an endentulous patient.

Potential use cases for this workflow include:

Best Practices 

1 Confirm the denture’s fit with the patient. 

  • In cases of poor retention, reline the denture with PVS material prior to scanning. Only use enough PVS materials to fill gaps with minimal overflow. 

2 Instruct patients to breathe through their nose, close their eyes, and place tongue at the back of the mouth. 

3 Review the scan carefully to ensure there is no “Black Air Space” between the denture and soft tissue of the patient. Use a bite registration (or cotton roles) for separation, secure fit,  and to eliminate rocking.


1 Place 6 x-ray markers (2 mm in diameter) around the surface of a dry, relined, well-fitting denture with no metal substructure. We highly recommend relining dentures with PVS material prior to scanning. We  recommend opaque markers such as Suremark VF-20 Stickers: 

  • 3 markers on the facial/buccal surface 
  • 3 markers on the palatal surface

2 Place the markers on varying axial planes. 

  • For example, if a marker is placed on the buccal area of #28-29, then place the next marker on the lingual area of #26-27, and the next marker on the facial area of #24-25. 

3 DO NOT place markers on the intaglio surface. 

First Scan 

Capture CBCT of the denture (with x-ray markers) 

1 Position the appliance on a foam block 

2 Orientate teeth occlusal down 

3 CBCT General Settings: Mand 6cm-8cm, 0.3-0.4 Voxel

Second Scan  

Capture CBCT of the patient wearing denture (with x-ray markers) 

1 Superior: Mid sinus / below orbit 

2 Inferior: Capture 1-3 mm of mandible dentition

3 CBCT General Settings: 6cm-8cm, 0.3-0.4 Voxel

Export and upload CBCT scans

Once your scans are complete follow the instructions to Export and upload CBCT scans
