The present study examines the T-Scan reproduction system used in occlusal diagnosis. The system represents a major technical innovation in functional diagnostics. Nevertheless, various aspects of it still require improvement. Amplifying or confirming the results of previous studies, the following observations are intended to indicate how the system might be improved, and how it can be reliably used at present: The reproduction afforded by the sensor as situated in the mouth is insufficient. Exact reproduction of the topography of the occlusal contacts is not possible. Reproducibility of the temporal sequence of the contacts is slight. The registering of dental functional movements can give rise to errors of interpretation. Threshold values for the registration of contact points in the system's pressure mode are uneven. The relative reproduction of different impressions is unreliable. Since in the system's pressure-mode early contacts cannot be distinguished from strong physiological contacts, in clinical practice the former must first be identified using the time-mode.
本研究对咬合诊断中使用的T-Scan再现系统进行了检验。该系统代表了功能诊断领域的一项重大技术创新。然而，其各个方面仍需改进。为了扩充或证实先前研究的结果，以下观察旨在表明该系统如何改进以及目前如何可靠地使用：位于口腔内的传感器所提供的再现效果不足。无法精确再现咬合接触的地形。接触时间序列的可重复性较差。牙齿功能运动的记录可能会产生解释误差。系统压力模式下接触点记录的阈值不均匀。不同印模的相对再现不可靠。由于在系统的压力模式下，早期接触无法与强烈的生理接触区分开来，因此在临床实践中，必须首先使用时间模式来识别前者。
