Abstract　： [ABSTRACT] This study was investigated the potentiality of a system in analyzing mandibular condyle motion dynamics, in which a TLI (Tissue Locus Imaging) method, which is based on the strobe action and afterimage effect, was applied to ultrasonography for the examination of the motion dynamics of the condyle motion in a non-invasive, quick, and simple way. 1, It was possible to visualize the motion dynamics of the condylar process in a non-invasive, quick, and simple way using our system in which an ultrasonograph was operated in combination with the TLI method. 2, TLI mode could demonstrate the motion dynamics of the condylar process more clearly, compared with B mode. 3, TLI mode, subjects showing no abnormal motion dynamics of the condylar process at axography had a cone-shaped pattern, while those with a limitation of jaw motion had a linear pattern. 4, Subjects with Down syndrome had a linear pattern in TLI mode, suggesting the possibility that they would have abnormal motion dynamics of the condylar process.
