Working toward the international standardization of dental magnetic attachments

牙科磁性附着体最有效的吸力测量方法是双轴夹具和高灵敏度拉力试验机相结合。由于现有的设备测量系统使用夹具和高性能的拉力试验机，对夹具和拉力试验机的通用性和性能都提出了很高的要求，使用多个装置需要简化和改进设计，以提高测量效率和降低成本。为此，研制了一种简化的吸力测量装置，该装置将夹具和拉力试验机合并为一个单元。本文对该装置的测量精度和试验情况进行了综述。实验结果证明了这种新型吸力测量装置的实用性和高效性。

The most effective attractive force measuring method of a dental magnetic attachment is considered to be a combination of biaxial jig and high sensitivity tension testing machine. As the existing device measuring system utilizes the jig together with a high performance tension testing machine, high versatility and performance are required for both jig and the tension testing machine.The use of multiple devices required simplification and design improvements for efficiency of measurements and reduction of cost. A simplified attractive force measuring device was thus developed that includes both jig and tension testing machine into a single unit. This paper reviews the measurement accuracy and testing of the new device. The results demonstrate the utility and efficiency of this new attractive force measurement device.
