title: Measuring pressures under maxillary complete dentures during swallowing at various occlusal vertical dimensions. Part I: A new hydraulic pressure measuring system.
abstract: This study presents a "closed" hydraulic pressure measuring system capable of measuring pressures at the denture base-mucosal surface interface. Two pressure receptors are made in the denture base of a maxillary denture. The receptors are covered with a flexible membrane and are connected to pressure transducers by means of polyethylene tubes. The transducers convert the hydraulic pressures coming from the receptors to electrical signals. A polygraph is used to amplify and record the electrical signals. It is assumed that complete contact can be obtained between mucosa and the flexible membranes, which is the advantage of this system.
