Orofacial dyskinesia: Effective prosthetic therapy

A movement disorder, orofacial dyskinesia, is characterized by severe, involuntary, dystonic movements of the facial, oral, and cervical musculature. This condition has been associated with extrapyramidal disorders, including reactions to phenothiazine and l-Dopa therapy. However, certain edentulous...

Zusammenfassung:A movement disorder, orofacial dyskinesia, is characterized by severe, involuntary, dystonic movements of the facial, oral, and cervical musculature. This condition has been associated with extrapyramidal disorders, including reactions to phenothiazine and l-Dopa therapy. However, certain edentulous dental patients also were observed to have involuntary dystonic movements similar to, but less severe than, those of OFD. The symptoms of these dental patients responded favorably to prosthetic dental therapy. This suggested that similar dental therapy might be effective in the control of symptoms of OFD. Eight patients with confirmed diagnoses of orofacial dyskinesia wore dentures which had incorrect occlusions. Modifications to correct the denture occlusions effected dramatic symptom reduction in all patients. Disruption of dental proprioception may be an important factor in the genesis of OFD.
