Tardive Dyskinesia, Oral Parafunction, and Implant-Supported Rehabilitation

Abstract EN

Oral movement disorders may lead to prosthesis and implant failure due to excessive loading.

We report on an edentulous patient suffering from drug-induced tardive dyskinesia (TD) and oral parafunction (OP) rehabilitated with implant-supported screw-retained prostheses.

The frequency and intensity of the movements were high, and no pharmacological intervention was possible.

Moreover, the patient refused night-time splint therapy.

A series of implant and prosthetic failures were experienced.

Implant failures were all in the maxilla and stopped when a rigid titanium structure was placed to connect implants.

Ad hoc designed studies are desirable to elucidate the mutual influence between oral movement disorders and implant-supported rehabilitation.
