This study aimed at providing a gauge device (Ekontak et al Gauge K-Device) in order to analyze the forces applied to teeth and periodontal tissues during dental practices in vitro. This force gauge device can be used in the investigation of the possible defect generation to tooth structures when overloaded forces are applied during dental procedures in vitro. Ekontak et al Gauge K-Device consists of three units: the specimen's holder, a high-performance digital force gauge, and the support frame. The holder was fabricated by an Al alloy providing a steady detachable attachment between the specimens and the force gauge's pin connector. The clinical simulation was achieved with the use of a proper silicone material, selected to provide similar elastic behavior with the human periodontal ligament and to join the teeth inside a solid matrix of an acrylic resin. The digital force gauge is a high-speed collection and recording (1000 Hz) product coupled with data recording software. The forces developed to 15 specimens' root canals during lateral condensation and vertical compaction of cold gutta-percha obturation procedures were monitored, saved as graphs, CSV, and excel files and presented over time. The forces developed during vertical compaction (mean maximum force per obturation circle = 13.22 N) were more excessive than those during lateral condensation (mean maximum force per obturation circle = 10.14 N). In conclusion, Ekontak et al Gauge K-Device is provided as a modern gauge device, capable of performing clinical simulation in vitro, under the terms of its protocol.
本研究旨在提供一种测量装置（埃孔塔克等人的K型测量装置），以便在体外牙科操作过程中分析施加于牙齿和牙周组织的力。这种测力装置可用于研究在体外牙科手术中施加过载力时牙齿结构可能产生的缺陷。埃孔塔克等人的K型测量装置由三个单元组成：标本固定器、高性能数字测力计和支撑框架。固定器由铝合金制成，可在标本和测力计的销连接器之间提供稳定的可拆卸连接。通过使用合适的硅树脂材料实现临床模拟，该材料被选择为具有与人类牙周韧带相似的弹性行为，并将牙齿连接在丙烯酸树脂的固体基质内。数字测力计是一种高速采集和记录（1000赫兹）的产品，配有数据记录软件。在冷牙胶充填术的侧向加压和垂直加压过程中，对15个标本根管内产生的力进行了监测，保存为图表、CSV和Excel文件，并随时间呈现。垂直加压过程中产生的力（每个充填圈的平均最大力 = 13.22牛）比侧向加压过程中产生的力（每个充填圈的平均最大力 = 10.14牛）更大。总之，埃孔塔克等人的K型测量装置是一种现代测量装置，能够在其方案的条件下在体外进行临床模拟。
