APPARATUS FOR MEASURING TOOTH MOBILITY

摘要

A dynamic procedure to measure the movability of teeth wherein a given motion is applied to a tooth to cause a displacement and wherein the average displacement rate of the tooth is measured. The instrument implementing this procedure comprises means (4-8) for generating the given motion, means for releasing said given motion, (10-12), and means (13) for transmitting this given motion to the tooth. The tooth displacement is measured by a magnetic pickup (14) emitting an electric signal representing the tooth displacement to an electronic data-processing and display circuit.
