Abstract
The retention of complete dentures in patients with Parkinson’ s disease is often poor due to their constant dislodgement by involuntary movements of the tongue and lips. Furthermore, insertion of the overdenture is expected to be difficult due to their limited voluntary movements. This case is about the bimaxillary overdenture restoration where its retention and stability are improved, using magnetic attachment of remained roots of maxilla and two implant Locator® attachments of mandible in patients with Parkinson’ s disease. This report describes the fabrication of this functionally improved prosthesis.
