Einrichtung zum Messen der Zahnbeweglichkeit

摘要

An apparatus for measuring the teeth for looseness in a form of physical quantity of elasticity, viscosity and mass element includes a signal generator (10) producing analog signals that have a desired frequency and waveform, a vibration driver (14) for converting electrical signals supplied fromthe digital type oscillating generator (10) into a mechanical vibration, an impedence head (16) for detecting power and acceleration required to cause the teeth to oscillate, and an analysis device (18) which takes in the data on the power and acceleration detected by the impedence head (16) so as to obtain a physical quantity of the measured tooth.
