Oral appliances in the treatment of oromandibular dystonia: a systematic review.

Oromandibular dystonia (OMD) is a clinically and etiologically heterogeneous form of focal dystonia with variable social and functional implications. The results of pharmacological treatment and botulinum toxin infiltrations are often unsatisfactory. We performed a systematic review on the effects of oral and dental appliances in patients with OMD.

Spasmodic torticollis: the dental connection.

Spasmodic torticollis or cervical dystonia (CD) is the most common form of focal dystonia and is characterized by sustained abnormal muscle contractions in the head and neck area resulting in abnormal positioning or posturing of the head. The dystonic muscle spasms associated with spasmodic torticollis may affect any combination of neck muscles. Three cases are reported of spasmodic torticollis that were treated by a dental appliance with individual varying occlusal heights to open the maxillomandibular vertical dimension.

An intraoral neurocranial vertical distractor appliance provides unique treatment for Tourette's syndrome and resolves comorbid neurobehavioral problems of obsessive compulsive disorder.

Evidence has existed for many years that individuals with Tourette's syndrome (T.S.) have associated neurobehavioral comorbid disorders.
