A dental pantograph capable of measuring mandibulary movement includes right and left side housings have orthogonally located X, Y and Z scales. The housing further includes X, Y and Z scale transducers for reading reference marks on the respective scales. The scales are slidable with respect to the transducers. The housings are located adjacent to engagement members with one of the housing or the engagement member associated with the mandible and the other associated with the maxilla. The scales extend between the housing and the engagement member and move with respect to the transducers in the housing by movement between the housing and the engagement member. The transducers produce electrical output signals which are fed to an appropriate signal processor, such as a microprocessor, for producing a readout indicating the mandibulary movement.
