Calibration of T-Scan sensors for recording bite forces in denture patients

Although measurement of maximum voluntary biting force is an important indicator of health of the masticatory system, few commercially available transducers have been validated for routine clinical use. The T-Scan III system records distribution of relative forces around the tooth row during clenching, but not absolute forces. This study assesses the reliability of T-Scan sensors with and without protection materials and develops calibration curves that allow measurement of absolute forces with the T-Scan III.
