ABSTRACT:
A dental probe having a stylus which is connected through a rod to a three position transducer which produces three signals indicating the position of the probe at any point to which the probe is applied. The transducers are mounted on an index tray which is adapted to be fastened to the jaw of the patient. Thus the patient's jaw becomes the origin against which all measurements are made. A handle is connected to the probe in such a fashion that the dentist has three rotational degrees of freedom of movement without affecting the position of the end of the stylus. Contact between the tip of the stylus and the patient's tissue completes a circuit to turn on the recording mechanism which receives the transducers' outputs.
