A device for making it possible to visually provide a thorough knowledge of the activities of the masticatory muscles by optically measuring and displaying the EMG potential of the masticatory muscles at the time of matication for use in correcting abnormal and unbalance occlusion patterns. The device comprises a plurality of sets of electrodes (8) and (9) each set consisting of a pair of right and left electrodes, said electrodes being designed to be attached to the surfaces of the masseter and temporal muscles in both sides so as to detect electromyographic potentials in time of mastication, a means (A) for converting the electromyographic potentials detected by said electrodes (8) and (9) respectively into electrical signals for display, a display means (C) for selectively energizing said means (C) in response to the signal, the means (C) including display lines (L1) and (L2) of light-emitting members (12) and (13) which are independent of one another for each of the electrodes (8) and (9). The means (C) is mounted in a position in which a person to be examined (P) is enabled to watch the means (C).

A device for displaying masticatory muscle activities for use in correcting unbalanced and abnormal occlusion patterns characterized in that the device comprises a plurality of sets of electrodes (8) and (9) each set consisting of a pair of right and left electrodes, said electrodes being attachable to the surfaces of the masseter and temporal muscles on both sides of a face of a person to be examined so as to detect electromyographic potentials during mastication, a means (I), (II), (III), (IV) and (V) for converting the electromyographic potentials detected by said electrodes (8) and (9) respectively into electrical signals for display, a display means (C), and a means (B) for selectively energizing said display means (C) in response to said signals, said display means (C) comprising display lines (L1), (L2), (L3) and (L4) of light-emitting members (12) and (13) which are independent over one another for each of said electrodes (8) and (9) whereby the masticatory muscle activity can be displayed during a plurality of consecutive occlusions.
