The dental torque limiting device is a tool used to deliver a measured torque to implants and to their associated components. The torque delivery must be accurate and precise, especially when considering screw joints. Similar torque wrenches are used in various industries, and recommendations on calibration are provided by the International Organization for Standardization 6789-2:2017. It states that hand torque tools should be calibrated annually or more frequently if subjected to extreme temperature conditions such as steam sterilization. The International Organization for Standardization standard recommends that calibration may be performed by direct comparison of 2 torque devices provided that 1 is known to be within calibration. This technique article describes the procedures for fabricating a tool that couples 2 dental torque limiting devices. It may be used for calibrating and validating both electrical and mechanical torque limiting devices.

牙科扭矩限制装置是一种用于将测量到的扭矩传递到植入物及其相关组件的工具。扭矩传递必须准确准确，尤其是在考虑螺纹连接时。类似的扭矩扳手已在各个行业中使用，国际标准化组织6789-2：2017提供了有关校准的建议。声明指出，如果要经受极端温度条件（例如蒸汽灭菌），则应该每年或更频繁地对手动扭矩工具进行校准。国际标准化组织标准建议，只要已知两个扭矩装置在校准范围内，就可以通过直接比较两个扭矩装置来执行校准。这篇技术文章介绍了制造用于耦合2个牙科扭矩限制装置的工具的过程。它可用于校准和验证电气和机械扭矩限制设备。
