How to Capture the Necessary CHROME Patient Records

1. CHROME Photographs

Good CHROME photos

Full face full smile
Full face exaggerated smile
Full face profile
Centre retracted in occlusion
Left retracted in occlusion
Right retracted in occlusion

2. Master Casts / Impressions

Good master casts/impressions

Capture full palate
Capture most/all of the surrounding labial & lingual tissues, the vibrating line, the full roll
Are free of noticable holes, skips, voids, or bubbles

Helpful Guidelines

Most CHROME cases use a backup denture; please capture as much anatomy as you would for an immediate full denture.
It can be challenging to reach the entire vestibule with an IO scanner, but please try to capture as much of the palate as possible.
If there is distortion, please retake the impression. It is best to catch inaccuracies at the office.

Bad master casts/impressions

We cannot use master casts or impressions that do not meet the desired coverage per patient scenario (see record checklist for details), have distortion, or have noticeable holes, drags, bubbles, and voids.

3. Bite Registration

Good bite registrations

Capture full occlusion or CR bite.
Taken with the patient in a closed bite, in natural occlusion.
Taken with the patient’s prosthesis in mouth, if applicable.

Helpful Guidelines

Use enough material to capture the occlusion, but not too much as to open the bite.
Neuromuscular bites are accepted as well; these are often the best, most accurate bites.
If the patient is missing posterior stops, we recommend bite blocks or a JC Try-In. A JC Try-In appliance will stabilize the bite and help establish occlusion.

Bad bite registrations

We cannot use bite registrations that:

Only capture a narrow centric occlusion.
Used too much material, which separated the bite.
Were not captured with teeth in natural occlusion.

4. CBCT Scans

Dentate

Good dentate CBCT scans

Capture both arches.
Taken with the patient in an OPEN position.
Taken with the patient’s denture(s) out of the mouth, if applicable.

Helpful Guidelines

Have the patient bite on cotton rolls or the bite fork.
Place cotton rolls between cheeks and teeth for a better image.
If the field of view only allows one arch, send two individual scans of each arch.
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 dentate CBCT scans:

We cannot use dentate CBCT scans that:

Captured the patient in a closed position.
Captured the patient with their denture(s) in the mouth.

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:
