Mandible & TMJs: Radiographic Anatomy - Video Lesson

Hey, everybody. Welcome to today's lesson on radiographic anatomy, demonstrated on routine projections of the mandible and temporomandibular joints, or TMJs. In a previous lesson, we discussed the anatomy and which radiographic projections are routinely performed. So let's tie that information to the radiographs themselves. As a reminder, the routine radiographic projections of the mandible are axiolateral or axiolateral obliques and PA or PA axial, depending on the area of interest and patient condition. And the routine projection of the TMJs is the AP axial, modified town method. Take a look at this radio graph. What projection is being demonstrated? How do you know? Let's find out the answers to these questions. If you said this radiograph is a left axial lateral oblique projection of the mandible, you're correct. Let's take a look at the evaluation criteria to see how we know for sure. In this image, the ramus, condyloid, and
