Oral rehabilitation using osseointegrated implants in a patient with idiopathic torsion dystonia

Idiopathic torsion dystonia is a motor syndrome characterized by dystonic m ovements and postures in the absence of other neurologic deficits. The cond ition involves prolonged spasms of muscle contraction that distort the body into typical postures. Such distortions involving the head and the neck ma ke conventional denture use in edentulous patients very difficult. The pres ent paper reports on a patient with idiopathic torsion dystonia who was tre ated with a mandibular overdenture supported by endostea( implants, which e nabled the establishment of a stable occlusion and improved the dynamics of the masticatory muscles for chewing.
