What are scan protocol considerations for imaging TMJ?

TMJ series typically include teeth closed in CR bite and then a open full without bite block. Open full usually suggests having the patient open wide to a comfortable position that can be held for the duration of the scan.  Any additional TMJ views (splint, wax bite, etc.) should be based on a patient-specific need.

The closed scan should be a high resolution scan that includes all the maxillofacial structures.  The open scan can be a limited field of view scan of the TM joints taken at a lower resolution with a shorter scan time to reduce patient dose. 

When submitting TMD cases, please provide clinical observations such as popping, clicking, pain, limited opening and patient history.
