[Interpretation and misinterpretation in occlusion diagnostic radiography of the temporomandibular joint]

Methodical procedure is of considerable importance in interpreting radiographs of the temporomandibular joint. Under this aspect the technique used at the Dental School of the University of Zurich, Department of Prosthodontics, is described. Two principal steps are distinguished for the evaluation of a radiograph: valuation and interpretation. In order to make clear radiographic anatomy and characteristics of projection of the joint region two didactic models are introduced. Problems, limits and pitfalls in interpreting radiographs of the temporomandibular joint in oblique lateral projection are shown.
