Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a molar distalization orthodontic appliance. Background Art
[0002] In orthodontic clinical practice, cases of malocclusion accompanied by crowded teeth are relatively common. Usually, methods such as tooth extraction or molar distalization are used for treatment. Molar distalization is a commonly used non-extraction orthodontic method. This method corrects the relationship of molars by pushing the molars backward, expands the arch space, provides space for leveling and aligning, thereby maintaining the natural physiological state of the stomatognathic system and facilitating the stability of the occlusal relationship.
[0003] However, during the process of molar distalization, although multiple anterior teeth are used as anchorage to counteract the reaction force during the distal movement of the molars, it is found in clinical practice that due to the loss of anchorage, some patients still inevitably have the anterior teeth inclined towards the labial side. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a molar distalization orthodontic appliance, which solves the problem that during the process of molar distalization in the prior art, although multiple anterior teeth are used as anchorage to counteract the reaction force during the distal movement of the molars, it is found in clinical practice that due to the loss of anchorage, some patients still inevitably have the anterior teeth inclined towards the labial side.
[0005] To achieve the above purpose, the utility model provides a molar distalization orthodontic appliance, which includes a traction wire, multiple stoppers, a correction unit, and two traction components. Each traction component includes a connection wire, a loop, a housing, a spring, and a ring. The connection wire is arranged above the correction unit. The loop is fixedly connected to the connection wire and is located at the upper end of the connection wire. The traction wire passes through the loop, the housing, and multiple stoppers. The housing is fixedly connected to the loop. The ring is fixedly sleeved outside the traction wire and is located inside the housing. Two ends of the spring are respectively fixedly connected to the inner wall of the housing and the ring.
[0006] Wherein, the correction unit includes a guiding tube and multiple correction blocks. The multiple correction blocks are respectively arranged and sleeved on the guiding tube, and the lower end of the connection wire is fixedly connected to the upper end of the guiding tube.
[0007] Wherein, the molar distalization orthodontic appliance further includes a limiting plate, and the limiting plate is fixedly connected to one end of the traction wire.
[0008] Wherein, the molar distalization orthodontic appliance further includes two protection blocks, and the two protection blocks are respectively fixedly connected to the guiding tube and are respectively located at the left and right ends of the guiding tube.
[0009] Among them, each of the correction blocks has a first arc edge, and each of the stopper blocks has a second arc edge.
[0010] In an orthodontic appliance for pushing molars backward of the present utility model, the connecting wire is arranged above the correction unit. The collar is fixedly connected to the connecting wire and is located at the upper end of the connecting wire. The traction wire passes through the collar, the outer shell and a plurality of the stopper blocks. The outer shell is fixedly connected to the collar. The circular ring is fixedly sleeved outside the traction wire and is located inside the outer shell. Two ends of the spring are respectively fixedly connected to the inner wall of the outer shell and the circular ring. By respectively attaching a plurality of the stopper blocks to the labial muscles, and then through the elastic force of the spring, the traction wire is always pulled backward, so as to apply a reaction force and a counteracting force, so that the plurality of the stopper blocks always maintain a counteracting force with the labial muscles, preventing the anterior teeth from tilting towards the labial side.

[0018] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.
[0019] First Embodiment:
[0020] Please refer to Figures 1 to 4 , wherein, Figure 1 is a schematic structural diagram of the whole of the first embodiment of the present utility model, Figure 2 is a front view of the whole of the first embodiment of the present utility model, Figure 3 is of the present utility model Figure 2 A - A line sectional view of Figure 4 is of the present utility model Figure 3 Local enlarged view of part B of
[0021] The present utility model provides a molar distalization orthodontic appliance, which includes a traction wire 101, a plurality of stoppers 102, a correction unit, two traction assemblies, a limiting plate 103 and two protection blocks 104. Each of the traction assemblies includes a connecting wire 105, a collar 106, a housing 107, a spring 108 and a ring 109. The correction unit includes a guiding tube 110 and a plurality of correction blocks 111.
[0022] For this specific embodiment, multiple said stoppers 102 are respectively attached to the lip muscles, and then through the elastic force of the spring 108, the traction wire 101 is always pulled backward, thereby applying a reaction force and a counter force, so that multiple said stoppers 102 always maintain a counter force against the lip muscles, preventing the anterior teeth from tilting towards the lip side. And the spring 108 is wrapped by the housing 107 to prevent the spring 108 from pinching the lip muscles in the oral cavity when the spring 108 expands and contracts, causing damage to the user. By installing multiple said correction blocks 111 on the corresponding teeth and then through the cooperation of the guide tube 110, the teeth are corrected so that the teeth can grow neatly. Through the setting of the limit plate 103, when the spring 108 pulls the traction wire 101 to move, the situation that the traction wire 101 detaches from the collar 106 due to excessive moving distance is prevented. And the end of the traction wire 101 is protected by the limit plate 103, thereby preventing the end of the traction wire 101 from pricking the lip muscles in the oral cavity and causing damage to the user when moving. Since many users, after wearing the orthodontic appliance, when eating or speaking, the muscles in the oral cavity are very likely to touch the end of the guide tube 110, and the muscles in the oral cavity are very fragile, so it is very easy to cause damage to them. Therefore, through the setting of two said protection blocks 104, the end of the guide tube 110 is protected, thereby preventing it from damaging the user's oral cavity and improving the safety of the device during use.
[0023] Among them, the connecting wire 105 is arranged above the correction unit. The collar 106 is fixedly connected to the connecting wire 105 and is located at the upper end of the connecting wire 105. The traction wire 101 passes through the collar 106, the housing 107 and multiple said stoppers 102. The housing 107 is fixedly connected to the collar 106. The circular ring 109 is fixedly sleeved outside the traction wire 101 and is located inside the housing 107. Two ends of the spring 108 are respectively fixedly connected to the inner wall of the housing 107 and the circular ring 109. Multiple said stoppers 102 are respectively attached to the lip muscles, and then through the elastic force of the spring 108, the traction wire 101 is always pulled backward, thereby applying a reaction force and a counter force, so that multiple said stoppers 102 always maintain a counter force against the lip muscles, preventing the anterior teeth from tilting towards the lip side. And the spring 108 is wrapped by the housing 107 to prevent the spring 108 from pinching the lip muscles in the oral cavity when the spring 108 expands and contracts, causing damage to the user.
[0024] Secondly, multiple correction blocks 111 are respectively arranged and sleeved on the guiding tube 110, and the lower end of the connecting line 105 is fixedly connected to the upper end of the guiding tube 110. By installing multiple correction blocks 111 on corresponding teeth and then through the cooperation of the guiding tube 110, the teeth can be corrected so that the teeth can grow neatly.
[0025] Meanwhile, the limiting plate 103 is fixedly connected to one end of the traction line 101. Through the setting of the limiting plate 103, when the spring 108 pulls the traction line 101 to move, the situation that the traction line 101 detaches from the collar 106 due to excessive moving distance is prevented, and the end of the traction line 101 is protected by the limiting plate 103. Thus, the situation that the end of the traction line 101 pricks the lip muscles in the oral cavity and causes damage to the user during movement can be prevented.
[0026] In addition, two protection blocks 104 are respectively fixedly connected to the guiding tube 110 and are respectively located at the left and right ends of the guiding tube 110. Since many users' oral muscles are easily touched by the end of the guiding tube 110 when eating or speaking after wearing the orthodontic appliance, and the oral muscles are very fragile, it is easy to cause damage to them. Therefore, through the setting of the two protection blocks 104, the end of the guiding tube 110 is protected, thereby preventing it from causing damage to the user's oral cavity and improving the safety of the device during use.
[0027] When using a molar distalizing orthodontic appliance according to this embodiment, multiple said stoppers 102 are respectively attached to the labial muscles, and then under the elastic force of the spring 108, the traction wire 101 is always pulled backward, thereby applying a reaction force and a counter force, so that multiple said stoppers 102 always maintain a counter force against the labial muscles, preventing the anterior teeth from inclining towards the labial side. And the spring 108 is wrapped by the outer shell 107 to prevent the spring 108 from pinching the labial muscles in the oral cavity when the spring 108 expands and contracts, causing injury to the user. By installing multiple said correction blocks 111 on the corresponding teeth and then through the cooperation of the guiding tube 110, the teeth are corrected so that the teeth can grow neatly. Through the setting of the limiting plate 103, when the spring 108 pulls the traction wire 101 to move, the situation that the traction wire 101 breaks away from the collar 106 due to excessive moving distance is prevented. And the limiting plate 103 protects the end of the traction wire 101, thereby preventing the end of the traction wire 101 from pricking the labial muscles in the oral cavity and causing injury to the user when moving. Since many users, after wearing the orthodontic appliance, when eating or speaking, the muscles in the oral cavity are very likely to touch the end of the guiding tube 110, and the muscles in the oral cavity are very fragile, so it is very easy to cause injury to them. Therefore, through the setting of two said protection blocks 104, the end of the guiding tube 110 is protected, thereby preventing it from causing injury to the user's oral cavity and improving the safety of the device during use.

[0030] The present utility model provides a molar distalizing orthodontic appliance, each said correction block 111 has a first arc edge 201, and each said stopper 102 has a second arc edge 202.
[0031] For this specific embodiment, through the setting of the first arc edge 201, after the user wears the device, when speaking or eating, the anterior lip of the user is prevented from being scratched by the edge of the corresponding said correction block 111. Through the setting of the second arc edge 202, after the user wears the device, when speaking or eating, the anterior lip of the user is prevented from being scratched by the edge of the corresponding said stopper 102.
[0032] Among them, each of the correction blocks 111 has a first circular arc edge 201, and each of the stopper blocks 102 has a second circular arc edge 202.
