Outline of Final Research Achievements

In this study, we assembled and evaluated a measuring system for 3-D movements (attitude angle) of the denture using an Inertial Measurement Unit. The attitude angles calculated by this system reduced by 3-4%. The measurement accuracy of this system was equivalent to that of 3-D motion capture system by four infrared TV cameras. As a pilot clinical trial, the attitude angles of three upper complete dentures during tapping were measured by this system.
This system is reliable and easy to analyze the attitude angle of the denture at low cost, and may serve a diagnostic appliance such as occlusal examination in a denture.
