Soundness of stomatognathic system can be achieved with a functionally adequate occlusal contact. A study on this occlusal morphology requires the analysis of micro tooth movement as well as analysis of jaw movement. The purpose of this study was to investigate micro upper first premolar movement under several occlusalloading conditions. Our jaw tracking device was modified to develop the new motion analyzer in six-degree-of-freedom that can perform simultaneous measurement of tooth and jaw movements.<BR>The results were as follows:<BR>1. The resolution of the recording system was improved up to 1.3 μm for translation and 0.00017° for rotation.<BR>2. Three male adult volunteers were selected as the subjects. Movements of right upper first premolars against left upper first premolarsof these subjects were measured with this device. Occlusal load was provided perpendicularly on buccal cusp, central fossa, palatal cusp and canine cusp. Directions of tooth movements of these subjects were almost the same under the same loading conditions.<BR>3. In some loading conditions, the rotation centers of tooth movement were found.
