Three-dimensional Movements of a Maxillary Complete Denture: The Development of a Measuring System and Preliminary Measurement

To measure the movements of a maxillary denture in vivo it necessary to analyze the three-dimensional displacements induced. A measuring system consisting of four main units (a magnetic sensor, three optical fiber sensors, a sensor-setting jig, and a recorder) was developed. Using this system, the movements of a maxillary denture were continuously measured during tapping and during the mastification of a peanut.
