In some possible embodiments, the mechanical sensor comprises a six-axis mechanical sensor.
The performance index of the dental appliance may be defined by a combination of forces and moments on three coordinate axes X, Y, Z in a cartesian coordinate system. A variety of six-axis mechanical sensors have been developed that can simultaneously measure 3 force components and 3 moment components, which can be implemented by a variety of principles such as resistive strain, piezoelectric, optical, capacitive, inductive, etc. For example, for a six-axis mechanical sensor with a relatively wide application range, the basic working principle is that the elastic body structure is deformed under the action of external force, so that a strain gauge attached to the elastic body is strained, thereby causing the change of a resistance value, and then the change of the resistance value is converted into the change of voltage or current through a circuit. In the piezoelectric six-axis mechanical sensor, the piezoelectric material generates charges under the action of external stress, and when the external force changes, the charges on the surface of the piezoelectric material change, so that the output voltage signal changes. The six-axis mechanical sensor can be used for well measuring the acting force and the rotating moment applied by the tooth appliance in the three-dimensional space, so that the physiological state of a human body can be intelligently simulated. The force value changes in three directions of X, Y, Z shafts can be detected simultaneously through the six-shaft mechanical sensor, and the torque values in the three shafts can be detected.

It is conceivable that a device for positioning the movable tooth and detecting the stress condition of the movable tooth is also provided on the other side of the anchorage tooth 150, which will not be described in detail herein.
The movable teeth 170 are spliced to the anchorage teeth 150, and an appliance is sleeved after the splicing is completed. The stress conditions of the supporting tooth 150 and the moving tooth 170 are detected by the first mechanical sensor 111 and the second mechanical sensor 133, the stress conditions are uploaded to a computer by the mechanical sensors, the magnitude and the direction of resultant force are calculated by calculating the magnitude of component forces in all directions of the supporting tooth 150 and the moving tooth 170, and judgment is made by the direction marks of the first axis X+ and the second axis Y+ on the base plate 100, so as to judge whether the stress direction of the moving tooth 170 is consistent with the design expectation.

The correction effect of the correction device can be prejudged through detection, the design modification is facilitated, the restarting rate of the correction scheme is reduced, and the production cost and disputes are reduced.
The detection device for the correction force of the invisible appliance provided by the disclosure can also be used for development work of novel appliance materials and used as an experimental device for material mechanics analysis.
As can be seen from the above, the detection device for the correction force of the invisible appliance provided by the present disclosure uses the force sensor to detect the stress condition of the movable teeth after the movable teeth and the movable teeth are spliced neatly by the linear guide rail module, and judges whether the direction of the stress of the movable teeth is consistent with the design expectation or not, so as to detect whether the correction force of the invisible appliance accords with the design expectation or not, so as to reduce the risk of correction failure.
