TMJ Survey

Diagnosing TMJ Disorders?

While most dental panoramic film will give you some indication of TMJ disorder, they are generally regarded as having low sensitivity and excel only mainly in the case of gross pathoses. Cone Beam CT presents as an alternative to the panoramic film as well as Medical CT due to its higher resolution and lower radiation dose. The scans are advantageous in extensively demonstrating the condition of the cortical plate and in detecting osteophyte formation.
