ABSTRACT:
An apparatus for measuring the teeth for looseness in a form of physical quantity of elasticity, viscosity and mass elements. The apparatus including a signal generator producing analog signals that have a desired frequency and waveform, a vibration driver for converting electrical signals supplied from the digital type oscillating signal generator into a mechanical vibration, an impedance head for detecting force and acceleration required to cause the teeth to oscillate, and an analysis device which takes in the data on the force and acceleration detected by the impedance head so as to obtain a physical quantity of the measured tooth.
