[Linear model of the etiology of temporomandibular pain dysfunction syndrome].

The investigation searched if a relatively complete, empirically tested model of the etiology of the mandibular dysfunction can be set up. The so-called LISREL- (Linear Structural Relationship) method was used for statistic evaluation. All factors showing a direct connection with the anamnestic and clinical dysfunction index were built into the model. The results led to the conclusion that anxiety and constitutional joint factors also play a role in the occurrence of mandibular dysfunction. The most important etiological factors are given by malocclusions, by occlusal interferences, impaired general state of health and parafunctions.
