Best x-ray for TMJ implant:
a. Computed tomography ***
b. Arthrography
c. Panoramic
Tomography give better visualization of TMJ than plain x-ray (dental secret)
The complexity of structure and functions of (TMJ) make the diagnosis of its diseases/disorders difficult. Remarkable progress made in the field of imaging of this joint led us to compare four imaging modalities viz. plain radiographs, CT scan, MRI and ultrasound. We found that MRI was most specific and sensitive for interpretation of soft tissue and inflammatory conditions in the joint, whereas CT examination produced excellent image for osseous morphology and pathology. Plain X-rays are useful for destructive bony changes and sonography is a good in aid in diagnosing disc derangement and is very economical.
