Cine MRI of the TMJ: need for initial closed mouth images without the Burnett device.
OBJECTIVE
To evaluate the Burnett device when studying functional and morphologic aspects of internal derangements of the temporomandibular joint (TMJ) with cine MRI.


METHODS
A patient with clicks in the TMJ cycle was studied with dynamic cine MRI both prior to the placement of the Burnett device and with the Burnett device in position.


RESULTS
Review of MRI revealed clear anterior displacement of the disk in relation to the condylar head in true closed mouth position without the Burnett device in place.


CONCLUSIONS
Closed mouth off-sagittal imaging of the disk in the closed mouth position should be included prior to appliance placement to detect anterior displacements with very early recapture.
