The illustrated embodiment employs a field generator, preferably a magnetic field generator, field flux pick-ups arranged at an interval therefrom, as well as an electronic device for the three-dimensional comprehension and evaluation of electrical signals arising in a field flux or a change of field flux. For displaying random points (P2 . . . Pn) of the lower jaw (1), means are provided which identify the geometrical attitude of the points with respect to a fixed-body coordinate system (xo, yo, Zo) allocated to the lower jaw whose origin and rotational center is the measuring point (P1). Further, a coordinate converter is provided which converts the coordinates (xo, yo, zo) related to the lower jaw into the coordinates ( DELTA x2, DELTA y22 DELTA z2) of the stationary coordinate system (X, Y, Z). Further, summing amplifiers are provided which add the adjustment magnitudes ( DELTA x2, DELTA y2, DELTA z2) of the jaw-related coordinates to the coordinates (x1, y1, z1) of the measuring point (P1). The device is particularly employed in gnathography.
