Problems solved by technology

It has been reported abroad that an industrial measuring robot with six degrees of freedom is used to measure the orthodontic force of the arch wire. The basic method is that the force measuring element is a sensor, and the arm with six degrees of freedom is used to make the bracket reach the specified position. Obviously This device is very expensive, and there is no such device in China

Embodiment 1

[0038] The measuring device for measuring orthodontic force in vitro includes a carrier plate 2 with a T-shaped slot 1 and positioning bolts. On the vertical end plates 3 oppositely arranged on the carrier plate, two holes are respectively opened on the two vertical end plates 3, and the four bolts 4 are respectively matched with the four holes on the two vertical end plates and installed on the vertical end plates. On the end plate 3, a nut 5 is installed at one end of each bolt, and the other end of the four bolts is pinned with a six-degree-of-freedom ball head 6, and the ball head 6 is installed on the ball sleeve 7, and the ball sleeve 7 is connected to the The end cover 8 is connected with bolts, and four springs 9 are connected with the end cover 8. The space measuring device is composed of a guide rail pair 10, a guide rail slider 11, a vertical distance measuring rod 12, a horizontal distance measuring rod 13 and a horizontal distance measuring device. The probe 14 on...

Abstract

The invention provides a device and a method based on combination of in vivo impression taking and in vitro impression measurement, and belongs to the technical field of force measurement, in particular to measurement of the orthodontic force of an oral cavity. The device for in vitro measurement of the orthodontic force of the oral cavity comprises a model clamping and positioning device, a marking and positioning device, a force measuring device and a coordinate measuring device. The measuring system has the characteristics of simple structure, convenient operation, and capability of conveniently obtaining the orthodontic force at any moment during the orthodontic process, predicting movement of teeth and providing guidance for orthodontic clinics.

Description

technical field [0001] The invention belongs to the technical field of force measurement, in particular to the measurement of orthodontic force. Background technique [0002] Orthodontics is to align misplaced teeth by applying external force through the appliance. Applying orthodontic force is the only means to achieve tooth movement. The study of the effect of external force on teeth in the process of orthodontics is of great significance to orthodontic theory and clinical practice. The orthodontic force is realized through the deformation force caused by the displacement between the predetermined shape of the archwire and the actual arrangement shape of the teeth. The orthodontic force measurement under is very difficult. It has been reported abroad that an industrial measuring robot with six degrees of freedom is used to measure the orthodontic force of the arch wire. The basic method is that the force measuring element is a sensor, and the arm with six degrees of freed...
