Description

Technical Field

[0001] The utility model belongs to the technical field of teeth correction equipment, and in particular relates to an auxiliary device for pushing molars backwards during orthodontic treatment. Background Art

[0002] In orthodontic clinic, Angle Class II malocclusion with crowded dentition is common. It is usually treated by extraction and non-extraction methods. Currently, non-extraction treatment is more popular. Since the 1990s, non-extraction treatment has been popular in clinic. Pushing molars distally is a more commonly used non-extraction treatment method. Its advantages are that it maintains the natural physiological state of the oral and maxillofacial system, and the operation is relatively simple, the treatment course is short, and it is conducive to the stability of the occlusal relationship.

[0003] The auxiliary device for pushing molars backward in orthodontic treatment is a common non-extraction orthodontic treatment device. It is a device that connects the inside and outside of the oral cavity and transmits the force outside the oral cavity to the inside of the oral cavity. It is composed of an intraoral bow and an extraoral bow. The extraoral bow uses the support of the skull outside the oral cavity to generate a force on the intraoral bow. The intraoral bow cooperates with the teeth to generate a force on the teeth. The disadvantage of the traditional auxiliary device for pushing molars backward in orthodontic treatment is that the intraoral bow is inserted into the buccal tube set on the teeth to connect with the teeth. It is often necessary to partially bend the intraoral bow to limit the length of the intraoral bow inserted into the buccal tube so that the intraoral bow can generate a force on the teeth. This operation process is complicated. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0021] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] See also Figure 1 On the one hand, the embodiment of the utility model provides an accessory 8 for connecting an archwire 3 and a dental brace, comprising a sleeve 1 and a spring 2. The sleeve 1 is sleeved on the archwire 3, and the spring 2 is connected to the sleeve 1 to provide a force acting on the teeth.

[0023] The sleeve 1 is sleeved on the arch wire 3, so that the sleeve 1 can be connected to the arch wire 3, and then the position of the spring 2 relative to the arch wire 3 can be fixed. The sleeve 1 and the arch wire 3 can be bonded, or the sleeve 1 sandwiches the arch wire 3 therebetween, so that the relative position between the sleeve 1 and the arch wire 3 can be relatively fixed.

[0024] When the intraoral bow needs to be inserted into the hole-shaped structure, for example, when the intraoral bow needs to be inserted into the buccal tube, the sleeve 1 is installed at a suitable position of the arch wire 3, and the arch wire 3 is inserted into the hole-shaped structure until the spring 2 abuts against the hole-shaped structure, for example, the spring 2 can abut against the end surface of the buccal tube, and the length of the arch wire 3 inserted into the hole-shaped structure is limited. In addition, the spring 2 abuts against the hole-shaped structure, so that the force applied to the intraoral bow can be transmitted to the teeth, so as to achieve the purpose of shaping the teeth.

[0025] In the embodiment of the present application, the material of the spring 2 can be nickel-titanium alloy. The advantage of the attachment 8 of the embodiment of the present application is that, on the one hand, by adjusting the position of the sleeve 1 sleeved on the arch wire 3, the length of the intraoral bow inserted into the hole-like structure can be adjusted, and the operation is convenient and simple. On the other hand, the force of the intraoral bow is transmitted to the teeth through the spring 2, and the spring 2 can buffer the force of the intraoral bow on the teeth, reducing the risk of excessive instantaneous force applied by the intraoral bow on the teeth and damaging the teeth. Furthermore, there is no need to move the position of the sleeve 1. By moving the position of the intraoral bow in the hole-like structure to adjust the degree of compression of the spring 2, the magnitude of the force of the intraoral bow on the teeth can be adjusted, making the adjustment more convenient.

[0026] In some embodiments, the sleeve 1 is configured to be deformed by an external force to clamp the archwire 3.

[0027] Specifically, after the sleeve 1 is installed at a designated position of the arch wire 3 , the sleeve 1 is clamped by using a tool such as pliers or clamps so that the sleeve 1 can be deformed to clamp the arch wire 3 .

[0028] The advantage of this connection method is that the sleeve 1 and the arch wire 3 can be fixed without using adhesive, thereby improving the safety of the accessory 8 to the human body. In addition, the operation method is simple and fast.

[0029] In some embodiments, the sleeve 1 may be made of metal, and the sleeve 1 and the spring 2 may be welded. Alternatively, the sleeve 1 may be provided with a mounting hole, and the end of the spring 2 may be inserted into the mounting hole and then rotated, so that the spring 2 may be spirally passed through the mounting hole, so that the spring 2 and the sleeve 1 may be detachably connected.

[0030] See also Figure 2 On the other hand, the embodiment of the present application also provides an auxiliary device for orthodontic treatment of pushing molars backward, comprising an inner arch wire 6 and an outer arch wire 7, and also comprising a connecting portion and the attachment 8 in the above embodiment. The connecting portion is used to connect with the teeth, and the connecting portion is provided with a perforation for the inner arch wire 6 to pass through. The sleeve 1 is sleeved on the inner arch wire 6, and the spring 2 is provided between the connecting portion and the sleeve 1.

[0031] The outer arch wire 7 is used to transmit the external force to the inner arch wire 6 so that the inner arch wire 6 can be acted upon by the force.

[0032] The inner arch wire 6 is used to act on the teeth to achieve the purpose of shaping. The specific principle of shaping teeth by the outer arch wire 7 and the inner arch wire 6 is well known to those skilled in the art, and the content involved in this application is not to improve the inner arch wire 6 and the outer arch wire 7 themselves to improve their shaping effect, so the structure of the outer arch wire 7 and the inner arch wire 6 will not be repeated here.

[0033] When the inner arch wire 6 is inserted into the through hole, the spring 2 can abut against the connecting portion, so that the length of the inner arch wire 6 inserted into the through hole can be adjusted.

[0034] See also Figure 1 In some embodiments, the inner arch wire 6 is passed through the spring 2.

[0035] The inner arch wire 6 is passed through the spring 2 , which, on the one hand, makes the force exerted by the spring 2 on the connection part more uniform, and on the other hand, reduces the risk of the spring 2 bending and damaging the connection between the spring 2 and the sleeve 1 .

[0036] See also Figure 1 In some embodiments, the connection portion includes a connection sleeve 4 and a matching portion 5. The connection sleeve 4 is sleeved on the peripheral surface of the tooth, a perforation is set in the matching portion 5, and the matching portion 5 is connected to the connection sleeve 4.

[0037] The connecting sleeve 4 is sleeved on the peripheral surface of the teeth so that the connecting part can be connected to the teeth, and further the force of the intraoral bow can be transmitted to the teeth through the connecting sleeve 4.

[0038] The matching part 5 may be a buccal tube, and in this case the perforation is a hole-like structure of the buccal tube.

[0039] The through hole of the matching part 5 is used for the intraoral bow to pass through, so that the intraoral bow can be connected to the connecting part. The spring 2 of the attachment 8 can abut against the matching part 5.

[0040] In some embodiments, the connecting sleeve 4 is an incomplete sleeve-shaped structure with two ends disconnected.

[0041] The connecting sleeve 4 may be formed by bending a metal plate-like structure.

[0042] The two ends of the connecting sleeve 4 are disconnected, so that the connecting sleeve 4 can adapt to teeth of different sizes, that is, after the connecting sleeve 4 is sleeved on the tooth, the two ends of the connecting sleeve 4 are closed, so that the connecting sleeve 4 can clamp the tooth tightly. In addition, by separating the two ends of the connecting sleeve 4, the stirrup effect of the connecting sleeve 4 can be eliminated, which makes it easy to remove the connecting sleeve 4 from the tooth.

[0043] In some embodiments, the connection sleeve 4 and the matching portion 5 are made of stainless steel, and the matching portion 5 is welded to the connection sleeve 4 .

[0044] The stainless steel material has good oxidation resistance and will not release harmful substances, which improves the safety of the auxiliary device for orthodontic treatment of pushing molars backwards to the human body, and enables the connecting sleeve 4 and the matching part 5 to be welded, thereby improving the connection reliability of the connecting sleeve 4 and the matching part 5.

[0045] See also Figure 3In some embodiments, a headgear is further included, and the headgear includes a forehead band 9, a back head band 10, a back neck band 15, and an integration band 11. The forehead band 9 is used to be clamped on the forehead of the head, the back head band 10 is used to be clamped on the back of the head, the back neck band 15 is used to be clamped on the back of the head, and the integration band 11 connects the forehead band 9, the back head band 10, and the back neck band 15. The integration band 11 is provided with a plurality of connection holes 14 at intervals, and the connection holes 14 are used for connecting the external arch wire 7.

[0046] The headgear is used to connect with the external arch wire 7. The headgear generates a force on the external arch wire 7. The force of the external arch wire 7 is transmitted to the internal arch wire 6, thereby enabling the internal arch wire 6 to exert a force on the teeth.

[0047] The forehead strap 9, the back of the head strap 10 and the back of the neck strap 15 work together to apply force to the external arch wire 7, which improves the comfort of the human body on the one hand and improves the stability of the headgear when pulling the external arch wire 7 on the other hand.

[0048] The integration band 11 connects the forehead band 9, the back of the head band 10 and the back of the neck band 15, so that the forehead band 9, the back of the head band 10 and the back of the neck band 15 can jointly exert force on the external arch wire 7. Furthermore, by adjusting the connection hole 14 connected to the external arch wire 7, the direction of the force applied to the external arch wire 7 can be adjusted.

[0049] The integration band 11 is provided with a plurality of connection holes 14 , which facilitates adjustment of the magnitude of the force applied to the external arch wire 7 on the one hand, and facilitates adjustment of the direction of the force applied to the external arch wire 7 on the other hand.

[0050] The integration band 11 may be made of plastic material, which increases the structural strength of the integration band 11, so that the integration band 11 can withstand the reaction force of the external archwire 7. A fitting layer 12 may be provided on the side of the integration band 11 close to the human body to increase the comfort of the headgear when it is put on the human body.

[0051] In some embodiments, a reinforcement ring 13 is provided on the inner peripheral wall of the connection hole 14 .

[0052] The reinforcement ring 13 may be a metal ring.

[0053] By providing a reinforcing ring 13 in the connecting hole 14 , the strength of the connecting hole 14 is increased, and the risk of the connecting hole 14 being damaged by the reaction force of the external arch wire 7 is reduced.

[0054] In some embodiments, the external arch wire 7 is provided with a connecting cable 16 , and the connecting cable 16 is passed through at least one connecting hole 14 .

[0055] Compared with directly hooking the external arch wire 7 on the connecting hole 14, connecting the external arch wire 7 and the connecting hole 14 through the connecting rope 16, on the one hand, it is convenient to adjust the direction of the force of the headgear on the external arch wire 7, and on the other hand, by adjusting the length of the connecting rope 16, the external arch wire 7 can be connected to different connecting holes 14.

[0056] The connecting cable 16 can be connected to a plurality of connecting holes 14 at the same time, further increasing the direction of the force that can be applied to the external arch wire 7 and increasing the connection strength between the external arch wire 7 and the connecting holes 14 .

[0057] The connecting rope 16 may be a nylon rope.

[0058] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
