背景：TheraMon(R)微传感器是为测量可拆卸设备的磨损时间而开发的最新设备。目的：确定1)TheraMon(R)微传感器在口腔内固定时是否准确记录时间，以及2)口腔内位置对记录时间的影响。方法：使用方便的样本，在英国一家医院正畸科进行了一项前瞻性的初步研究。五名非患者志愿者在7天内佩戴微型传感器，分别放置在上颌磨牙和下颌磨牙上。计算实际磨损量与每个设备记录的磨损量之间的差异。结果：上、下部微型传感器记录的平均日磨损时间为23h(95%可信区间22.6~23.4)，平均漏录4%(可信区间2.5~5.8%)。每天最大的少报磨损时间为5.5小时。结论：TheraMon(R)微型传感器软件所做的假设会导致口腔内磨损时间的漏报，特别是当放置在腭部时。这些差异在临床实践和研究中都可能是显著的。微传感器软件参数的调整将提高准确性，无论口腔内的位置如何。
Background: The TheraMon (R) microsensor is the most recent device developed to measure the wear-time of removable appliances. The accuracy has not been validated intraorally.Objectives: To determine 1) if the TheraMon (R) microsensor accurately records time when fixed intraorally, and 2) the effect of the intraoral location on the recorded time.Methods: A prospective pilot study, using a convenience sample, was carried out in a UK hospital orthodontic department. Five non-patient volunteers wore microsensors positioned palatal to an upper molar, and buccal to a lower molar for 7 days. Differences between actual amount of wear and the wear recorded by each device were calculated. Differences between sites were also examined.Results: The mean daily wear-time recorded by the upper and lower microsensors combined was 23 hours (95% CI 22.6-23.4), which is a mean under-recording of 4% (CI 2.5-5.8%). The maximum daily under-reporting of wear times was 5.5 hours. Microsensors in the lower buccal sulcus recorded wear-times that were closer to actual wear-times.Conclusions: Assumptions made by the TheraMon (R) microsensors software lead to under-reporting of intraoral wear-time, particularly when placed palatally. These discrepancies could be significant in both clinical practice and research. Adjustment of the microsensor software parameters would improve accuracy, irrespective of the intraoral location.
