[Properties of a measuring system for digital occlusion diagnosis]

The properties of a new digital technique of demonstrating and quantifying occlusal contacts (T-scan) were tested in vitro the sensor foil used was 95 microns in thickness and had approx. 1350 measuring points. When a given force was applied at the same point on one foil several times in sequence, the readings were highly reproducible. Applying the same force at different points on the same foil and at points on different foils, however, failed to bring about reproducible results. The reasons for this lack of reproducibility and possible modifications are discussed.
