The following workflow is for capturing a CBCT on an endentulous patient. Already completed your scans? Follow the instruction here to export and upload your CBCT .
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.
Setup
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
