Introduction: Axiography allows the three-dimensional study of condylar movements in the perspective of a diagnosis of cranio- mandibular dysfunctions and a real adjustment of the articulator. Can we do without an MRI magnetic resonance imaging examination and rely solely on axiographic plots in the diagnosis of CMD and can we systematize an axiographic mapping?
Materials and methods: This is a descriptive clinical study through which we treated 20 partial dentated and edentulous patients with signs and symptoms of TMJ disorders, the age group is 31 y old to which we have made axiographic plots, these have been superimposed with those of DUPAS in order to try to contribute to the systematization of an axiographic cartography.
Results and Discussion: The graphic recordings differ from one patient to another; the experience of the practitioner remains a major asset for the interpreters and consequently to make the positive diagnosis of the articular pathology. The value of the condylar slope was between 38° and 70°, the angle of Bennett is calculated according to the Hanau formula. We also noticed that the return movements do not necessarily end at the point of reference (arbitrary hinge axis).
Conclusion: Despite the absence of an axiographic mapping of condylar trajectories and pending further studies, axiography is of very significant diagnostic importance, indeed as and when it is used, the practitioner will master its rational use.
