Use of a submental-vertex analysis for producing quality temporomandibular joint laminagraphs.
A radiographic analysis which can be used to produce high-quality laminagraphs of the temporomandibular joint has been presented. Submental-vertex radiographs of twenty-six dry skulls and fifty vital subjects were used as the sample. Statistical examination demonstrated a wide range of condylar angulations and midline-to-condyle distances. These two measurements are critical to the production of laminagraphs used for pathologic diagnosis of TMJ dysfunction. The results of this study seem to verify the need for an accurate method of determining these two influential quantities.
