Background: The relationship between occlusal discrepancies and TMJ disorders does not always hold true. Nonetheless, occlusal analysis is a requisite to achieve a correct diagnosis in the dysfunctional patient. Many studies show that occlusal discrepancies can be a very important etiological factor. Material and Methods: Various literature reviews describe the main occlusal types and the possibility of structural and functional relationships with TMJ derangements. Results: The relationship between each kind of malocclusion and a specific TMJ disorder is due to different condyle positions in the glenoid fossa. It may be appropriate to introduce the term Tooth-Condyle Unit because the stomatognathic system has a specific bone block or mandible, which encompass teeth and condyles. The various occlusal schemes can be considered dynamic which influences the joint. Conclusion: The involvement of occlusion in the etiology of TMJ disorder is conditioned by the presence of other factors. However, physiologic occlusion must be re-established for correct joint function. This implies that the specific biomechanics of each patient and it's correlation with biological parameters must be known in order to provide joint homeostasis.
