[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0024] This invention relates to an orthodontic appliance for vertical traction, which provides vertical traction force to the patient's teeth to be treated. It can guide ectopic erupted and impacted teeth to move in the correct direction, avoiding problems such as insufficient traction force or inaccurate direction, and improving the treatment effect of orthodontic treatment.
[0025] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the orthodontic appliance for vertical traction includes an appliance body 1, which has at least one connector 11. The appliance body 1 is connected to a traction hook 2 via the connector 11, and the traction hook 2 is positioned below the tooth to be treated. The traction hook 2 is used to connect to an elastic element to provide vertical traction force to the tooth to be treated.
[0026] In this embodiment, after the orthodontic appliance body is installed on the patient's teeth, the traction hook 2 is connected through the connector 11 and positioned below the tooth to be treated. When the elastic element is connected between the traction hook 2 and the tooth to be treated, the elastic force of the elastic element can provide vertical traction force to the tooth to be treated, thereby guiding ectopic erupted and impacted teeth to move in the correct direction, avoiding problems of insufficient traction force or inaccurate direction, improving the treatment effect of orthodontic treatment, shortening the treatment cycle, and reducing patient pain.
[0027] It should be noted that, to ensure the stability of the orthodontic appliance, the appliance body has an upper alveolar groove on the upper side and a lower alveolar groove on the lower side. During treatment, the upper teeth match the upper alveolar groove, and the lower teeth match the lower alveolar groove to support and fix the entire appliance, ensuring that the appliance will not wobble and affect the treatment effect. At the same time, it reduces the stimulation of oral soft tissues and improves the patient's wearing comfort.
[0028] It should also be noted that the structure, placement, and angle of the traction hook 2 can be customized according to the position and direction of the patient's tooth to be treated, ensuring that the direction of the traction force is accurate, making the treatment process more controllable and enhancing the predictability of the treatment.
[0029] The elastic element is preferably a rubber band.
[0030] In this embodiment, the traction hook 2, positioned below the tooth to be treated, ensures that a vertical traction force is provided to the tooth. To ensure that the traction hook 2 can be positioned below the tooth to be treated, the connection between the traction hook 2 and the connector 11 can be implemented using the following example:
[0031] In the first embodiment, the connector 11 is disposed below the tooth to be treated. Therefore, after the traction hook 2 is connected to the connector 11, the traction hook 2 is vertically arranged below the tooth to be treated, thereby ensuring that after the elastic element, such as a rubber band, is hung on the traction hook 2, the elastic element can provide vertical traction force to the tooth to be treated.
[0032] The second implementation method, such as Figure 5 As shown, the traction hook 2 is connected to the connector 11 via the mounting rod 21, and a first lateral distance d1 is formed between the connector 11 and the tooth to be treated. The lateral projection length d2 of the mounting rod 21 is equal to the first lateral distance d1. Therefore, after installing the traction hook 2 onto the connector 11 using the mounting rod 21, it ensures that the traction hook 2 is positioned below the tooth to be treated, guaranteeing that the traction hook 2 can provide vertical traction force to the tooth to be treated through the elastic element.
[0033] It should be noted that in the second embodiment, two connectors 11 can be arranged, and the two connectors 11 are located on both sides of the main body 1 of the orthodontic appliance. The mounting rod 21 is a curved metal strip formed on both sides of the traction hook 2. The traction hook 2 is wrapped around the connectors 11 on both sides by the curved metal strips on both sides, thus completing the arrangement of the traction hook 2 on the main body 1 of the orthodontic appliance. The length of the curved metal strip can be adjusted according to the actual position of the tooth to be treated, ensuring that the traction hook 2 is located below the tooth to be treated after being connected to the connector 11 by the curved metal strip, thus ensuring that the direction of the traction force is accurate.
[0034] To facilitate the connection of the traction hook 2 to the connector 11, such as Figure 3 and Figure 4 As shown, a hook-and-loop gap 12 is formed between the main body 1 of the orthodontic appliance and the connector 11, and the hook-and-loop gap 12 is located on the side of the connector 11 away from the tooth to be treated. Thus, the traction hook 2 can be hooked to the connector 11 through the hook-and-loop gap 12 to ensure the connection stability between the traction hook 2 and the connector 11.
[0035] Furthermore, the tow hook 2 has a hooking portion, through which the tow hook is hooked to the hooking gap 12. Specifically, if the tow hook 2 is a small ring structure, the hooking portion can be the bottom section of the tow hook 2; if the tow hook 2 is a small hook, the hooking portion can be a claw formed at the bottom of the tow hook 2. The width of the hooking gap 12 is greater than the vertical thickness of the hooking portion, so that the hooking gap 12 can provide sufficient hooking space for the tow hook, realizing the rapid hooking of the tow hook at the connector 11.
[0036] In this embodiment, since tooth movement during orthodontic treatment may require repositioning of the traction hook 2, to facilitate adaptive adjustment of the position of the traction hook 2 during treatment, such as... Figure 1 and Figure 2 As shown, the main body 1 of the orthodontic appliance has an adjustment groove 13. The adjustment groove 13 is located above the connector 11 so that the adjustment groove 13 provides adjustment space for the doctor, thereby facilitating the doctor to make fine adjustments to the position of the traction hook 2 as needed, so that the traction hook 2 can be kept below the tooth to be treated, ensuring that the direction of the traction force is accurate.
[0037] Among them, such as Figure 1 and Figure 2 As shown, the width of the connector 11 is smaller than the width of the adjustment groove 13, so that the doctor can use relevant tools (such as probes) to adjust the lateral position of the traction hook 2 relative to the adjustment groove 13, further enhancing the adjustment flexibility of the traction hook 2. In some embodiments, the difference between the width of the adjustment groove 13 and the width of the connector 11 can be 0.3mm-0.5mm, so as to facilitate adjustment while preventing the traction hook 2 from detaching from the connector 11.
[0038] In this embodiment, to accommodate traction hooks 2 with different structural shapes, the relative position between the groove 13 and the connector 11 can be adjusted according to the actual situation. The following example illustrates the arrangement of the groove 13 and the connector 11 when mates with traction hooks 2 of certain shapes:
[0039] The first arrangement method, such as Figure 1 and Figure 3 As shown, when the traction hook 2 is a small annular traction hook 2, the adjusting groove 13 is formed on the outer side of the main body 1 of the orthodontic appliance, and the connecting member 11 is located inside the adjusting groove 13. A hooking gap 12 is formed between the bottom surface of the connecting member 11 and the bottom surface of the adjusting groove 13. Therefore, when hooking the annular traction hook 2, the annular traction hook 2 can be inserted into the connecting member 11, and the bottom of the annular traction hook 2 can be embedded into the hooking gap 12 to complete the connection between the traction hook 2 and the connecting member 11 and ensure the installation stability of the traction hook 2.
[0040] The second arrangement method, such as Figure 2 and Figure 4 As shown, when the traction hook 2 is a hook, the connector 11 is located on the outer side of the orthodontic body 1, the adjusting groove is located on the top of the connector 11, and a hooking gap 12 is formed between the side of the connector 11 facing the orthodontic body 1 and the outer side of the orthodontic body 1. Therefore, when attaching the hook, the bottom claw of the hook can be attached through the hooking gap 12, completing the connection between the traction hook 2 and the connector 11, and ensuring the installation stability of the traction hook 2.
[0041] In this embodiment, an auxiliary support (not shown in the figure) is provided on the inner side of the main body 1 of the orthodontic appliance. The auxiliary support is used to fit and contact with the teeth, so as to enhance the retention force of the orthodontic appliance, increase the contact area between the orthodontic appliance and the tooth surface, and improve the overall strength and stability of the orthodontic appliance.
[0042] Specifically, the auxiliary support is a reinforcing rib or a support rod. The specific distribution position of the reinforcing rib or support rod on the inner side of the main body 1 of the orthodontic appliance can be arranged according to the force situation of the main body 1 of the orthodontic appliance to further ensure the accuracy of the direction of the traction force, reduce the stimulation of the oral soft tissue, and improve the patient's wearing comfort.
[0043] In this embodiment, the main body 1 of the orthodontic appliance is made of polymer material or metal material so that the main body 1 of the orthodontic appliance can have good biocompatibility and transparency or strength, thereby further improving the patient's wearing comfort.
[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
