Edentulous
Good edentulous CBCT scans:
- Follow a dual scan protocol.
- Use the patient’s well-fitting denture or scan appliance in the mouth during the scan.
- Capture a scan of the patient with their denture(s) in the mouth, in occlusion, not separated.
- Capture a scan of the denture(s) alone resting on foam.
Helpful Guidelines
- If the patient has a good denture: Prepare by placing 6 scan markers (www.suremark.com)
or 6 gutta-percha markers randomly in the pink area of the labial flanges. - If the patient has a poor denture: Either fabricate a new denture, perform a hard reline, or
place blue mousse inside the denture to stabilize it. Soft relines are NOT acceptable. - If the patient does not have a denture: A new denture or scan appliance must be fabricated.
- The scan must include the patient from the chin up to the nasal cavity.
- Do not scan the patient alone without their denture.
- Export DICOM files (.dcm) from the CBCT into a patient folder- this should contain 200-400 individual .dcm files. Zip the patient folder and upload with Rx.
Bad edentulous CBCT scans
We cannot use edentulous CBCT scans that:
- Captured the patient without their denture in the mouth.
- Captured the patient with their denture not fully seated against the tissue.
- Used a poorly-fitting denture for the scan.
- Used a denture with a soft reline for the scan.
- Captured the extraoral denture scan not on foam, but plastic or metal.
