Description

TECHNICAL FIELD

[0001] The utility model belongs to dental orthodontic equipment technical field, and particularly relates to a non-end molar pressure device. BACKGROUND

[0002] After long absence of molar, the opposite molar will extend to the direction of the missing tooth, resulting in insufficient space for the implant of the missing tooth. If the implant of the missing tooth is needed, the extended molar needs to be pressed down to obtain sufficient space for the implant of the missing tooth.

[0003] However, after the non-end molar is extended, the mesial movement of the back tooth will squeeze the sagittal space of the non-end extended molar, resulting in insufficient sagittal space to accommodate the non-end extended molar, which makes it impossible to press down the non-end extended molar. Therefore, before pressing down the non-end extended molar, the sagittal space of the non-end extended molar needs to be restored to press it down.

[0004] The above-mentioned restoration of the sagittal space and the conversion of the pressing down process cannot be completed by a single appliance in the current treatment method. It can only be done by first bonding local brackets on the adjacent teeth (front teeth and back teeth) of the non-end extended molar to locally align, and then pushing the back tooth of the non-end extended molar with a push spring to obtain sufficient sagittal space.

[0005] Then, one micro-implant anchorage is implanted on the buccal side and lingual side of the front tooth of the non-end extended molar, or the bracket on the front tooth is replaced with a pressure device with a traction hook as a fulcrum. The two ends of the chain-shaped rubber band are hung on the fulcrum, and the middle part crosses the occlusal surface of the non-end extended molar to gradually press down the non-end extended molar.

[0006] The above-mentioned method generally has the following disadvantages:

[0007] 1) During the bonding of local brackets, the use of arch wires for local alignment may change the occlusion and cause discomfort;

[0008] 2) The implantation of micro-implant anchorage is a invasive operation, which some patients cannot accept;

[0009] 3) If the interradicular space of the patient is insufficient or the bone density is low, the micro-implant anchorage may fail to be implanted;

[0010] 4) The process of removing the bracket and replacing the pressure device is complicated. Therefore, it is a technical problem to be solved by those skilled in the art to provide a non-end molar pressure device that can shorten and simplify the pressure process. UTILITY MODEL CONTENTS

[0041] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0042] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In the embodiments of this application, such as Figures 1 to 6 As shown, the non-terminal molar depressor includes a first ring 1, a second ring 2, a reset element 3, and a depressor elastic band 4; wherein,

[0045] The first band 1 and the second band 2 can be respectively fitted onto the adjacent teeth at the anterior and posterior ends of the molar to be corrected (non-terminal elongated molar). A depressor hook 5 is provided on the lingual side of the first band 1. The movable end of the depressor hook 5 is also located on the lingual side of the first band 1, and extends to the middle position between the first band 1 and the second band 2. That is, the movable end of the depressor hook 5 extends between the first band 1 and the second band 2. (See [reference]). Figure 1 ;

[0046] The two ends of the repositioning member 3 are connected to the buccal side of the first band 1 and the buccal side of the second band 2, respectively. The repositioning member 3 can push the first band 1 and the second band 2 away from the molar to be corrected in the sagittal direction. Since there are still teeth at the end of the adjacent teeth at the front of the molar to be corrected away from the molar to be corrected, while there are no teeth at the rear end of the molar to be corrected, when the repositioning member 3 pushes the first band 1 and the second band 2, the position of the adjacent teeth at the front of the molar to be corrected changes little, and the adjacent teeth at the rear end of the molar to be corrected can move towards the rear end of the molar to be corrected, so as to increase the sagittal space of the molar to be corrected.

[0047] One end of the depressor 4 is connected to the middle of the repositioning member 3, and the other end of the depressor 4 is connected to the movable end of the depressor traction hook 5 after passing around the occlusal surface of the molar to be corrected.

[0048] The first band ring 1 and the second band ring 2 in the non-terminal molar pressing-down device can be respectively sleeved on the adjacent teeth at the front and rear ends of the molar to be corrected. The first band ring 1 and the second band ring 2 are pushed by the resetting member 3, so as to push the adjacent teeth at the rear end of the molar to be corrected in a direction away from the molar to be corrected, so as to restore the sagittal space of the molar to be corrected. Meanwhile, the resetting member 3 and the pressing-down rubber band 4 hung on the pressing-down traction hook 5 can press down the molar to be corrected. Therefore, the non-terminal molar pressing-down device can complete the combined operation of restoring the sagittal space and pressing down the molar to be corrected without replacing the appliance during the treatment, so as to simplify the operation of pressing down the molar to be corrected, and make the pressing down of the molar to be corrected more convenient, safe and efficient.

[0049] In some embodiments, the first band ring 1 includes a ring body A11 and a ring body B12, wherein

[0050] The ring body A11 and the ring body B12 are arranged along the sagittal direction to form an "8" shape structure, as shown in the figure, so that the ring body A11 and the ring body B12 can be respectively sleeved on the two consecutive teeth at the front end of the molar to be corrected. Figure 5

[0051] The end of the resetting member 3 away from the second band ring 2 and the fixed end of the pressing-down traction hook 5 are respectively connected with the buccal side of the ring body A11 and the lingual side of the ring body A11.

[0052] In some embodiments, the ring body A11 and the ring body B12 are integrally formed, so that the structure of the first band ring 1 is more stable.

[0053] In some embodiments, the resetting member 3 is a "N" shape structure made of Australian silk, and the included angle between the axes of the two ends of the resetting member 3 and the axis of the middle part of the resetting member 3 is 30°-45°. The two ends of the resetting member 3 are respectively inclined away from the middle part of the resetting member 3, as shown in the figure. Figure 6

[0054] When the resetting member 3 is installed, the two ends of the resetting member 3 are pressed towards the middle part, and the two ends of the resetting member 3 are respectively connected with the first band ring 1 and the second band ring 2.

[0055] The two ends of the resetting member 3 will push the first band ring 1 and the second band ring 2 away from the middle part of the resetting member 3 under the influence of the restoring force, that is, the adjacent teeth at the rear end of the molar to be corrected are pushed away from the molar to be corrected, so as to increase the sagittal space of the molar to be corrected. Preferably, the middle part of the resetting member 3 is provided with a bending part 31, and the bending part 31 is a "U" shape. The opening of the bending part 31 is arranged opposite to the opening of the resetting member 3.

[0056] ​​When the compression elastic band 4 is fixed, the end of the compression elastic band 4 can be clamped into the bending part 31 to limit the position of the compression elastic band 4, avoid the compression elastic band 4 sliding along the length direction of the reset member 3 to cause the compression elastic band 4 to be separated from the reset member 3, and ensure the compression effect of the non-terminal molar compression device.

[0057] In some embodiments, the buccal side of the first band 1 is provided with a first sleeve 13, and the buccal side of the second band 2 is provided with a second sleeve 21, as shown in Figures 1 to 3 The two ends of the reset member 3 are inserted into the first sleeve 13 and the second sleeve 21 from the root to the crown direction, so that the installation of the reset member 3 is more convenient. Figure 3 Figure 6 ;

[0058] When the end of the reset member 3 is inserted into the first sleeve 13 or the second sleeve 21 along the axis direction of the first sleeve 13 or the second sleeve 21, the first limiting part 32 can limit the insertion depth of the reset member 3, and also can avoid the position of the reset member 3 changing during the orthopedic process to cause the non-terminal molar compression device to fail.

[0059] When the end of the reset member 3 passes through the first sleeve 13 or the second sleeve 21, the end of the reset member 3 can be bent to form a second limiting part 33 to avoid the reset member 3 being separated from the first sleeve 13 or the second sleeve 21.

[0060] In some embodiments, the first sleeve 13 and the second sleeve 21 are fixed on the first band 1 and the second band 2 by welding to improve the stability of the structure of the non-terminal molar compression device.

[0061] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.​
