Embodiment Construction
[0051] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.
[0052] Such as Figure 1 to Figure 2 As shown in 1, the embodiment of the present invention provides a fixing device for measuring orthodontic friction force, which includes four parts: a support, a telescopic fixed chuck, a rotating fixed chuck and a self-locking disc. The support acts as a fixation, enabling the device to be fixed on the table for subsequent operations; the tooth model can be tightened by rotating the telescopic fixed chuck; the measurement of orthodontic friction at different angles can be realized by rotating the fixed chuck; the self-locking disc can Realize the self-locking fixation of the tooth model every 30 degrees rotation.
[0053] The support includes: bearing housing 11, beam 16...

The invention relates to an auxiliary device for measuring a friction force of an orthodontic bracket and a measuring method. The device comprises a support, a telescopic fixed chuck, a rotary fixed chuck and a self-locking disc. A bearing seat and a cross beam form the support which is fixed on a table top through screws, and two ends are connected with the telescopic fixed chuck and the self-locking disc. The telescopic fixed chuck stretches out and draws back through a fixed short handle and a rotary cylinder chuck and is matched with the square-disc-shaped chuck at the other end to clamp amodel. And the rotary fixed chuck at the other end consists of a square disc-shaped chuck and a bearing seat with a long handle. A handle is rotated, and the fixed model is rotated through the connection of a steering wheel-shaped handle and the disc-shaped handle. A round hole for containing a spring and a steel ball is formed in the long handle and matched with the self-locking disc to achievea self-locking function. The invention belongs to an orthodontic friction force auxiliary measurement device which is convenient for researchers to measure orthodontic friction forces at different angles more simply, conveniently and quickly, greatly improves the orthodontic friction force measurement efficiency, and realizes pure mechanization without electric power support.
Description
technical field [0001] The invention relates to the technical field of auxiliary measurement of orthodontic friction force, in particular to an auxiliary device and a measurement method for measuring the friction force of orthodontic brackets. Background technique [0002] In the process of orthodontics, we generally use fixed aligners. When using a fixed orthotic, there is a certain amount of friction between the bracket of the fixed orthotic and the arch wire, and when the bracket and the arch wire slide, a certain amount of frictional resistance will be generated. Studies have proved that orthodontic friction will affect the movement of patients' teeth, and there is a range of force values for the most effective movement of teeth. When there is friction, in addition to considering the optimum force for tooth movement, the magnitude of friction should also be considered. Therefore, how to reduce the frictional resistance between the bracket of the fixed aligner and the...
