title: Complete denture prosthodontics for a patient with Parkinson's disease using the neutral zone concept: a clinical report.
abstract: A patient with Parkinson's disease was given new dentures made by utilizing the neutral zone concept. Many modeling oral functions (including swallowing, phonation, sucking, smiling, and grimacing) and two materials were used to shape six neutral zone impressions but only one impression was deemed satisfactory for the patient. The patient's lack of neuromuscular control coupled with xerostomia made it impossible to construct a denture with perfect, absolute equilibrium and no displacement; however, denture stability was improved considerably and the patient wore the dentures for several years. Based on this case, a slow-setting material of low viscosity was preferable for shaping the neutral zone.
