Transcranial radiography has the benefit of providing low equipment cost, and it does not require additional space. The diagnosis of the internal derangement can be made on the basis of the measurement of the joint space by using transcranial
radiograph. Thus transcranial radiography is one of the most commonly used radiographic techniques of the diagnosis of TMJ disorders.
It is generally known that the transcranial radiograph delineates the lateral third of the condyle. This article intends to help reader understand the morphology of the condylar bony structures thought the transcranial radiography.
Four radiopaque wire were palced on the condylar surface at intervals of two millimeter from the lateral pole. Using 20 dry mandibles and an Accurad-200 headholder (Denar Corp. U.S.A.). The transcranial radiographs were taken.
@ES The results were as follows:
@EN 1. The wires that are attached at the distance of 2mm from the lateral pole delineate the anterior partition of the condylar outline in the standard and corrected transcranial radiographs.
2. The anterosuperior partition of the condylar outline consists of the image of the wires that are attached at the distance of 2.4mm from the lateral pole.
3. The posterosuperior partition of the condylar outline consists mainly of the image of the wires that are attached at the distance of 4.6mm from the lateral pole.
4. The posterior partition of the condylar outline consists mainly of the image of the wires that are attached at the distance of 6, 8mm from lateral pole.
