[Operative and diagnostic set-up for dysfunctional patients].

The application of the set-up for treatment planning and prognosis can be extended to the stimulation of the orthodontic teeth movements in the patients with TMJ dysfunctions, already repositioned, and with very severe dentoalveolar discrepancy in order to decide the indication for extractions and selection of the teeth to be extracted. The limits of this simulation always remain the function of the masticatory system. The sequences of the procedures on the articulator and the different steps on the upper and lower models are described. A patient with TMJ disorders and dento-alveolar discrepancy is presented with the different procedures of treatment as for the dysfunction as for the orthodontic problems.
