ABSTRACT:
An articulation detector for articulators of the kind wherein condylar elements mounted on a lower jaw member and glenoid fossae assemblies of an upper jaw member are made of a conductive material, comprises an electric power source, a luminous element and a pair of detecting electrode, all of which are connected in series. The electrodes are adapted to be connected to the lower jaw member and an incisal pin mounted on the upper jaw member of the articulator when the detector is in use. The adjustment of the articulator or prosthetic appliances may be detected by observing the light emitted from the luminous element.
