Functional adaptation with reformation of bone tissue structure occurs after changes in mechanical stress distribution. To examine how occlusal changes affect the dynamics of bone metabolism in the mandibular condyle, bone scintigraphy of rat condyles was taken using (99m)technetium-methylene-diphosphonate (99mTc-MDP) after extraction of maxillary molars(More)
The purpose of this retrospective cohort study was to investigate patient satisfaction factors that affect the usage of removable partial dentures (RPDs) using a multivariate analysis. Sixty-seven patients, who had RPDs inserted at the Tohoku University Hospital between 1996 and 2001, participated in this study. Data were collected from patients' clinical(More)
In conventional hard disk drives, a control system compensates for the vibration in which frequency is higher than the Nyquist frequency by using a multi-rate filter that can decrease the gain above the Nyquist frequency. However, such a control system can only avoid instability that results from mechanical vibrations and cannot suppress the vibrations. In(More)
