Positional changes of the magnet and sensor array of the MKG produce greats errors of its output data. To resolve this problem, we attempted to create an apparatus, the MKG Setter which could provide a set-up for a reproducible positional relationship among the sensor, the magnet, and craniofacial structure in calibrated conditions for day-to-day measurement. Testing of reproducibility with the MKG setter, that reproduced constant mandibular positions in four subjects, was performed by a well trained operator and three inexperienced examiners like a single blind test. The results indicated that the mean C.V. was 3% laterally, 7% anteroposteriorly, and 4% vertically. The average percentages of ranges to mean values were 17% laterally, 27% antero-posteriorly, and 11% vertically. The distance between the first measured value by well trained examiner and data of measurements 14 repeated after the second measurements were almost within 0.3mm, even if there were significant differences. We conclude that this system should be of considerable the use in attaining reproducibility when repositioning the sensor and the magnet to the craniofacial structure in day-to-day measurements. And it provid the common data in individual subjects by using reference plane.
