The present invention relates to a mandibular maxillo-mandibular jaw relation three dimensional digital recording device, which is a mandibular centric relation recording device having a recording device provided on a mandibular occlusion plane so as to support a stylus by a support plate and to record on a recording plate, and having a recording means for recording a mandibular maxillo-mandibular jaw relation on the recording plate fixed to an assembly in the form of Gothic arch by means of the stylus, the device comprising: a reproduction bar, which is added to one front spot and two rear spots of the support plate of the recording device, reproduces a mandible motion path on the assembly fixing the recording plate, and has an additional position recognition magnet on an upper end thereof a sensor unit concavely fixed to the assembly by making contact with the front end of the reproduction bar, and having a several distribution coils so as to recognize position movement of the magnet an analog/digital converter for converting a current value of each distribution coil, which is induced by the sensor unit, into a digital value and a microcomputer for storing digital values outputted from the analog/digital converter, and recording and reproducing the mandibular maxillo-mandibular jaw relation on the basis of the stored values, wherein the distribution coil of the sensor unit comprises a central coil for recognizing position movement of the center and an edge coil distributed and provided in each direction of the edge outside the central coil so as to recognize a moving direction toward the edge.La présente invention concerne un dispositif denregistrement numérique tridimensionnel de la relation mandibulaire de la mâchoire maxillo-mandibulaire, qui est un dispositif denregistrement dune relation mandibulaire centrée, présentant un dispositif denregistrement disposé sur un plan docclusion mandibulaire de manière à supporter un stylet par une plaque support et à enregi
