Abstract　： [Abstract] Computerized axiography, CADIAX (Gamma, Austria) made it possible to record the three dimensional movements of mandibular condyles which contribute to the objective assessment in functional diagnosis. However, it is also mandatory for a clinical application to evaluate accurate mechanical characteristics in this computerized system. Therefore, a study of the measuring analysis was performed using a three-dimensional automated apparatus, CAMM-3 (Roland Japan). One experiment was conducted to evaluate the total error occurring in this computer system caused by both the electronic flag and stylus. Another experiment was conducted to test the mechanical strength of the axiograph connected with each motion-detecting mechanism, and to find how this influences the measurement accuracy of the total system. From these experiments, the following results were obtained. 1) Measurement accuracy of the electronic flag varied depending on its site and its values were recorded approximately within 3 mm. 2) Measurement accuracy of the electronic stylus was homogeneous regardless of the degree of contraction within 0.07 mm. 3) Contact weight by the electronic stylus was assumed to be approximately 70 g, whereas the electronic flag displacement occurred in the distance within 1.0 mm during the measurement of mandibular movement.
