[Reduction of trigeminal neuralgia complaints after recovery of the vertical dimension].

A 56-year-old man was referred by his dentist to an orthodontist as part of an interdisciplinary treatment plan for a complete dental rehabilitation. The patient presented with a mutilated dentition with a restricted envelope of function and generalized severe tooth wear with loss of vertical dimension. The patient showed a history of multiple endodontically treated and subsequently extracted elements associated with unexplained symptoms until a neurologist diagnosed trigeminal neuralgia. The orthodontic treatment in which the restricted envelope of function was eliminated and the vertical dimension was reestablished resulted in a significant reduction of the number of triggers experienced by the patient.
