<p>PURPOSE:To securely detect slight abnormality such as early contact in a normal occlusion state or cuspal interference by adding a target head axial angle setting means to a head axial angle detecting means, detecting deviation to a set target axial angle and displaying the deviation by a head axial angle display means. CONSTITUTION:When the inclination of the head in a patient is detected by head axial angle detectors 2P and 2S, head axial angle signals are amplified by amplifiers 3P and 3S and inputted to differential amplifiers 5P and 5S. For example, when the set angle is 0 deg. in back and forth directions and right and left directions, reference signals are inputted from head axial angle setters 4P and 4S to the differential amplifiers 5P and 5S. Then, the differential amplifiers 5P and 5S compares the above mentioned head axial angle signals with the reference signals and outputs signals corresponding to difference to head axial angle displays 6P and 6S. According to the outputs of the differential amplifiers 5P and 5S, the head axial angle displays 6P and 6S display difference quantity between the head axial angle and a set value.</p> |
