Abstract. OBJECTIVES Oromandibular dystonia (OMD) is a focal dystonia manifested by involuntary muscle contractions producing repetitive, patterned mouth. Oromandibular dystonia is a form of focal dystonia affecting the mouth, jaw and tongue, and in this disease it is hard to speak. It is associated with bruxism. Oromandibular dystonia causes spasms of the jaw, lips, and tongue muscles. This dystonia can cause problems with speech and swallowing.

Although some cases of OMD have been reported after dental procedures, the causal relationship between these procedures and dystonia is still unclear.

Oromandibular dystonia

During these episodic contractions her jaws involuntarily closed and tongue deviated to the opposite side with slurring of speech and episodes of accidental tongue bite on several occasions.

Finding intraoral sensory trick and fabrication of prosthetic devices can help dental professionals to treat the symptoms of OMD.

Patients usually report triggers like stress, talking, dishonia something and praying. Marked reddening and an observable bulge were appreciated on the right half of forehead and jaw region. Dystonia is the most common prevalent movement disorder next only to Parkinson’s disease PD and essential tremor ET.

The electrophysiological data of these patients suggests that dystonia is associated with several changes in neuronal activity in striatal circuits such as an alteration in the rate, pattern, somatosensory responsiveness, and synchronization of neural activity in palladium thalamocortical circuits Figure 7 [ 7 ].

Etiology, Diagnosis and Management of Oromandibular Dystonia: an Update for Stomatologists

Korean Assoc Oeomandibular Maxillofac Surg. Patients with OMD may also suffer from hyposalivation; nevertheless, the pooling of saliva on intraoral examination was reported. By using this site, you agree to the Terms roomandibular Use and Privacy Policy. Grimacing, reddening, and breathlessness were the associated findings. To quantitatively assess the muscular contractions and to find the extent of muscle diztonia electromyographic study of the bilateral temporalis and masseter was done.


Electromyographic study of the bilateral temporalis and masseter reveals spontaneous fasciculations at rest. Furthermore, it can also be classified into the affected body parts depending on anatomical regions of distribution [ 14 — 6 ]. The authors declare no conflict of interest. Physiotherapy is thought to promote brain re-wiring over time, so oromandibbular to reduce the dystonic movements. N Z Dent J. Symptoms and Effects of Oromandibular Dystonia OMD The uncontrollable contractions and movements of this disorder can lead to many side effects.

Prompt diagnosis in the presented case formed the key to a successful management and improved the quality of life of a disheartened patient. Diagnosis and treatment of dystonia. Dystonia is classified as focal, segmental, multifocal, and generalized Figure 6. Tic disorders in school-age children are higher, with the more common tics of eye blinking, coughing, throat clearing, sniffing, and facial movements.

Complete resolution of symptoms while wearing the prosthesis was observed. Effective in stabilizing the oromandibular dystonic movements. There idstonia inadequate evidence-based information about the efficacy of various medications currently being distonua for dystonia.

It can also be categorized based on etiology. Abstract Oromandibular dystonia OMD is a movement disorder characterized by involuntary, paroxysmal, and patterned muscle contractions of varying severity resulting in sustained spasms of masticatory muscles, affecting the jaws, tongue, face, and pharynx.

Thorburn and Lee[ 15 ] discussed two OMD cases which occurred following extractions and full dentures. The TMJ remained asymptomatic during this period. MAB is a promising means of treating OMD, which is less expensive and cause no oromandibulwr side effect or resistance to the therapy.

The author suggested that the conventional techniques such as delayed loading, axial implant placement and BoNT injections could be used to reduce the oromandibluar movements with more predictable rehabilitation plan. Republic of Singapore English. Few investigations on BoNT injection before implant insertion demonstrated satisfactory results.

However, most patients usually complain of muscular tension or tiredness, and pain was quite rarely reported.

The author noted a huge loss of vertical dimension, which was restored through fabricating a provisional denture.

To progress the current medical and related health care options for patients with dystonia, excellent trials that study the efficacy of treatments are needed to be done. Oromandibular dystonia OMD is a movement disorder characterized by involuntary, paroxysmal, and patterned muscle contractions of varying severity resulting in sustained spasms of masticatory muscles, affecting the jaws, tongue, face, and pharynx.
