[0002] Orthodontic self-ligating brackets are commonly used corrective appliances in orthodontics. In order to ensure that orthodontic self-ligating bracket products meet clinical needs and safety standards, it is often necessary to conduct unlocking tensile tests on the self-ligating brackets produced. The test ensures that the locking mechanism of the bracket is both safe and reliable during orthodontic treatment. Too little unlocking force may cause the bracket to open accidentally, while too much force may make the opening process difficult, affecting the treatment effect and patient comfort. In the design and improvement process of new self-ligating brackets, the unlocking tensile test can be used to evaluate the performance of different designs and help develop more effective and comfortable orthodontic products.

The multi-angle simulated correction process self-locking bracket unlocking test structure of the utility model includes an upper clamping member 2 and a lower clamping member 1. The upper clamping member 2 and the lower clamping member 1 are respectively fixed to the corresponding force-applying parts of the tension test equipment, which are common parts of the prior art. That is, the upper clamping member 2 and the lower clamping member 1 can be respectively applied with the existing equipment to change the distance between the upper and lower clamping members. The specific force data collection and analysis adopt the existing technology, which will not be repeated here.

[0027] Specifically, Figure 1 As shown, the utility model provides a multi-angle simulated correction process self-locking bracket unlocking test structure, which includes an upper clamping member 2 and a lower clamping member 1 arranged on a tensile test device, and a self-locking bracket fixing assembly is arranged between the upper clamping member 2 and the lower clamping member 1, and the self-locking bracket fixing assembly is used to fix the self-locking bracket between the upper and lower clamping members. An unlocking hook assembly and a correction wire force application assembly are also arranged between the upper clamping member 2 and the lower clamping member 1; the unlocking hook assembly includes an unlocking hook 51 that can be inserted into the bracket unlocking hole; the correction wire force application assembly includes a correction wire simulation member 9 and a correction wire force application accessory. The self-ligating bracket fixing assembly includes a base plate 3 and a self-ligating bracket fixing member 4; the unlocking hook assembly includes an unlocking hook accessory 5 and an unlocking hook 51 arranged on the unlocking hook accessory 5; the correction wire force-applying assembly includes a correction wire simulation member 9 and a correction wire force-applying accessory, and the correction wire force-applying accessory acts on the correction wire simulation member 9 and applies force to the correction wire simulation member 9 at multiple angles. The correction wire force-applying accessory includes a pin rod 6 and a spring 8.

[0028] like Figure 2 and Figure 3 As shown, a bottom plate 3 is fixed on the lower clamping member 1, and a self-locking bracket fixing member 4 is provided at one end of the bottom plate 3. Figure 4 As shown, a first bracket fixing block 41 is provided on the self-locking bracket fixing member 4. Correspondingly, as Figure 6 As shown, a bracket second fixing block 32 is provided on the upper surface of the bottom plate 3. Figure 3 As shown, the self-locking bracket B is fixed by the first bracket fixing block 41 and the second bracket fixing block 32 clamping each other.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, an unlocking hook accessory 5 is connected to the lower part of the upper clamping member 2, and the end of the unlocking hook accessory 5 has an unlocking hook 51, which can be inserted into the unlocking hole of the self-locking bracket to apply force to the locking plate of the self-locking bracket, thereby opening the bracket locking plate.

[0030] like Figure 2 , Figure 3 and Fig.13 As shown, in order to simulate the force applied to the archwire of the self-ligating bracket at different angles during the correction process, a correction wire simulation part 9, a spring 8 and a pin 6 are also provided in the archwire groove of the self-ligating bracket. Figure 2 and Figure 5 As shown, the two ends of the spring 8 are respectively provided with a first spring connecting ring 81 and a second spring connecting ring 82. Preferably, there are two pins 6. The corresponding base plate 3 is provided with several rows of jacks 7 that penetrate or do not penetrate the base plate. The pin can also be handheld or fixed in a pin hole somewhere in the device. If handheld, the force application angle can be more angled. Alternatively, more jacks are provided on the base plate to increase the force application angle.

[0031] In order to allow the correction wire simulation part 9 to be firmly fixed in the archwire groove, one of the surfaces of the correction wire simulation part 9 has a groove 93, and the two side walls of the groove 93 are respectively arranged as a first clamping surface 91 and a second clamping surface 92, and the first clamping surface 91 and the second clamping surface 92 respectively cooperate with the first spring connecting ring 81 and the second spring connecting ring 82 of the spring 8.

[0032] When used specifically, there are several tension test modes: the first one, such as Fig.10 As shown, when the archwire is not subjected to force at other angles, the self-ligating bracket is subjected to a tension test. That is, when the tension is applied as indicated by the arrow, during the separation of the upper clamp 2 and the lower clamp 1, the unlocking hook 51 of the unlocking hook accessory 5 on the upper clamp 2 opens the locking piece of the self-ligating bracket and transmits the relevant data to the tension equipment system. Fig.11 As shown, in the first case, while applying force, the first connecting ring 81 of the spring 8 is fixed to one end of the correction wire simulation part 9, and the pin 6 pulls the second connecting ring 82 of the spring 8 into the insertion hole. In this way, the tension data of opening the self-ligating bracket lock piece when the arch wire is subjected to unilateral tension is simulated. Fig.12 As shown, in the second case, a force is added to the other end of the correction wire simulation part 9, that is, a pin rod 6 is added, and the added pin rod 6 pulls the spring second connecting ring 82 of another spring 8 and is inserted into another jack side by side. When the simulation correction wire simulation part 9 is subjected to tension on both sides at the same time, the tension data of opening the self-locking bracket lock plate. Furthermore, the change of the force applied to the simulation correction wire simulation part 9 can also be achieved by changing the position of the jack. Therefore, by adopting the above-mentioned different test modes, the unlocking tension data when the arch wire is subjected to force at different angles during the self-locking bracket correction process can be comprehensively obtained, and the design of the bracket self-locking force is more optimized. It is more conducive to improving the performance of self-locking bracket unlocking force and other aspects.

Any changes or substitutions that are not conceived through creative work should be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
