Traditional Occlusal Indicators VS. T-Scan Data

How repeatable/accurate is the T-Scan™ data?

In practice, analysis of occlusion is reduced to depicting it with color-marking foils. Precise analysis that incorporates time resolution and plots the distribution of forces within the occlusion is not possible in the everyday clinical situation with traditional methods.  T-Scan™ is a computer-assisted dental occlusion analyzer that depicts occlusion by means of biting onto a pressure sensitive sensor. The aim of our study was to test the accuracy and reliability of this method.

This study concludes that 95% of the time, the T-Scan system produces a measurement that is within 2% of the true value.  Also, repeat measurements produce very close values (within 2.8%), 95% of the time. Digital occlusal analysis data is measurable and comparable versus traditional occlusal indicators.
