  • Tooth displacement measuring apparatus
    Patent number: 4192321
    Abstract: An improved tooth displacement measuring apparatus for measuring the displacement of a test tooth in response to particular applied forces. A zero value selector automatically adjusts the measured values of tooth displacement with respect to a reference calibration displacement defined by the displacement measured in response to a calibration force. The measured values of displacement corresponding to the particular applied forces are stored and selectively displayed.
