Tardive Dyskinesia, Oral Parafunction, and Implant Supported Rehabilitation
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.
