Description

TECHNICAL FIELD

[0001] The present application relates to the field of orthodontics, and more particularly, to an orthodontic bracket transfer device. BACKGROUND

[0002] In fixed orthodontic treatment, the accuracy of bracket positioning and bonding plays a crucial role in the treatment outcome. If the position is accurate, the orthodontic force can guide the teeth to move in three-dimensional space (mesiodistal, labiolingual, and vertical) according to the orthodontist's design, thereby achieving the expected tooth arrangement and occlusal relationship adjustment.

[0003] Currently, there are mainly two ways to bond brackets. The first is the traditional manual bonding method, in which the doctor mainly relies on visual observation and manual operation to bond the brackets directly on the tooth surface. This method has obvious limitations, and the bonding time and accuracy depend largely on the doctor's clinical experience. Especially when dealing with the posterior region, it is difficult to achieve accurate observation perpendicular to the tooth surface due to the limited view of the oral cavity, which makes the bracket positioning prone to errors, thereby adversely affecting the orthodontic treatment outcome.

[0004] The second is the indirect bonding method, among which the compression film method is more common in current clinical applications. The compression film method involves manually drawing bracket positioning lines on the prepared plaster model, applying a separating agent, then positioning the brackets on the plaster model using adhesive, placing the plaster model under a compression film machine, transferring the brackets to the transfer tray made of film, and finally cutting and sterilizing the entire transfer tray according to the crowding of the dentition to meet the clinical use requirements. However, this method also has defects. In the process of making, the determination of bracket position relies on manual operation, which is inevitably disturbed by human factors, making it difficult to accurately control the direction and angle of bracket retention. For example, during the compression process, if the bracket accidentally falls off the plaster model, it needs to be repositioned and compressed. Or because the adhesive is not completely washed, the bracket cannot be successfully transferred to the tray. These problems not only take time and effort, but also are complex and tedious to operate.

[0005] Therefore, the existing technology needs to be improved. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to provide an orthodontic bracket transfer device to solve the problem that the existing bracket transfer process involves manual positioning of the bracket and then transferring it to the transfer tray for film making, which is time-consuming and complicated, and errors are difficult to avoid.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the embodiments of the present application is:

[0008] An orthodontic bracket transfer device, comprising:

[0009] A tooth positioning model, a plurality of tooth positions are arranged on the tooth positioning model, and each tooth position is provided with a tooth surface and a tooth crown;

[0010] A plurality of bracket positioning portions are arranged below the tooth surface of the corresponding tooth position, and a positioning groove corresponding to the bracket is arranged at the top end of the bracket positioning portion, and the positioning groove is used for initially connecting the bracket;

[0011] A plurality of positioners are arranged above the corresponding bracket positioning portion and are used for being sleeved on the corresponding tooth crown, and a bracket clamping portion corresponding to the bracket positioning portion is arranged on the positioner, and clamping arms are arranged on both sides of the bracket clamping portion, and the clamping arms are used for transferring and connecting the bracket.

[0012] According to the orthodontic bracket transfer device described above, the bracket limiting block is arranged on each tooth surface, and the bracket is arranged in the bracket limiting block in a matched mode.

[0013] According to the orthodontic bracket transfer device described above, the distance between the end of the bracket limiting block close to the bracket positioning portion and the bottom of the bracket positioning portion is greater than the distance between the end of the bracket close to the bracket positioning portion and the bottom of the bracket positioning portion.

[0014] According to the orthodontic bracket transfer device described above, the distance between the end of the bracket limiting block away from the tooth surface and the tooth surface is 0.3-0.5 mm.

[0015] According to the orthodontic bracket transfer device described above, the end of the bracket positioning portion close to the tooth surface is provided with a gingival avoidance groove.

[0016] According to the orthodontic bracket transfer device described above, the distance between the groove bottom surface of the gingival avoidance groove and the bottom of the bracket clamping portion is less than the distance between the groove bottom surface of the positioning groove and the bottom of the bracket clamping portion.

[0017] According to the orthodontic bracket transfer device described above, the two clamping arms are arranged on the mesial side of the bracket clamping portion and the distal side of the bracket clamping portion respectively.

[0018] According to the orthodontic bracket transfer device described above, the end of the positioner away from the tooth crown is provided with a tooth position marking portion.

[0019] According to the orthodontic bracket transfer device described above, the shape of the positioning groove is U-shaped.

[0020] The orthodontic bracket transfer device provided in the application has at least the following beneficial effects:

[0021] This application first embeds the bracket into the positioning slot, then presses the locator along the direction of the tooth positioning model to embed the bracket into the clamping part, where it is clamped and fixed by the two clamping arms. Since the bracket and the positioning slot are mechanically fixed, and the connection force between the bracket and the locator is greater than that between the bracket and the positioning slot, when the locator is separated from the crown of the tooth positioning model, the bracket on the locator will be taken away with it. The bracket can be accurately bonded to the human tooth surface through the separated locator. This application not only plays a role in accurately positioning the bracket, but also simplifies the process of medical personnel assembling brackets on the tooth model, realizing the transfer of brackets and rapid and accurate positioning on the teeth.

[0030] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application and not to limit the present application.

[0031] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component. The terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position shown in the drawings, and are only for the convenience of description, and cannot be understood as a limitation on the technical solutions. The terms "first", "second" are only for the purpose of convenient description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0032] In fixed orthodontic treatment, the accuracy of bracket positioning and bonding plays a crucial role in the treatment effect. If the position is accurate, the orthodontic force can accurately guide the teeth to move in three-dimensional space (mesiodistal, labial-lingual, vertical) according to the doctor's design, so as to achieve the expected tooth arrangement and occlusal relationship adjustment.

[0033] At present, there are mainly two ways of bracket bonding. One is the traditional manual bonding bracket method, in which the doctor mainly relies on visual observation and manual operation to bond the bracket directly on the tooth surface. This method has obvious limitations, and the bonding time and accuracy depend largely on the doctor's clinical experience. Especially when dealing with the posterior region, due to the limitations of the internal visual environment of the oral cavity, it is difficult to achieve accurate observation perpendicular to the tooth surface, which makes the bracket positioning prone to error, and thus adversely affects the orthodontic treatment effect.

[0034] Secondly, the indirect bonding bracket method, among which the compression film method is more common in current clinical application. The compression film method is to draw bracket positioning lines on the prepared plaster model, apply separating agent, then use adhesive to position the brackets on the plaster model, then place the plaster model under the compression film machine, use the compression film machine to transfer the brackets to the transfer tray made of film, and finally cut the whole transfer tray according to the crowding condition of the dentition to meet the clinical use requirements. However, this method also has defects. In its production process, the determination of the position of the bracket depends on manual operation, which is inevitably interfered by human factors, making it difficult to accurately control the direction and angle of the bracket retention. For example, during the compression process, when the bracket accidentally falls off the plaster model, it needs to be repositioned and compressed. Or because the adhesive is not completely washed, the bracket cannot be successfully transferred to the tray. The processing of these problems not only consumes time and effort, but also is complicated and tedious.

[0035] Therefore, according to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the orthodontic bracket transfer device provided by the embodiments of the present application comprises a tooth positioning model 1, a plurality of bracket positioning parts 2 and a plurality of positioners 3. The tooth positioning model 1 is provided with a plurality of tooth positions, each of which is provided with a tooth surface 11 and a tooth crown 12. The plurality of bracket positioning parts 2 are respectively arranged below the tooth surface 11 of the corresponding tooth position. The top end of the bracket positioning part 2 is provided with a positioning groove 21 corresponding to the gingival side of the bracket 4. The positioning groove 21 is used to initially connect the bracket 4 and stably fix the bracket 4 at the predetermined position. The plurality of positioners 3 are respectively arranged above the corresponding bracket positioning part 2 and are used to be sleeved on the corresponding tooth crown 12. The positioner 3 is provided with a bracket clamping part 31 corresponding to the bracket positioning part 2. The two sides of the bracket clamping part 31 are provided with clamping arms 32. The clamping arms 32 are used to transfer and connect the bracket 4.

[0036] The bracket 4 is first embedded into the positioning groove 21, and then the positioning device 3 is pressed in the direction of the tooth positioning model 1, so that the bracket 4 is embedded into the clamping part and is clamped and fixed by the two clamping arms 32. Since the bracket 4 is mechanically fixed with the positioning groove 21, and the connection strength between the bracket 4 and the positioning device 3 is greater than the connection strength between the bracket 4 and the positioning groove 21, when the positioning device 3 is separated from the tooth crown 12 of the tooth positioning model 1, the bracket 4 on the positioning device 3 is taken away together. The bracket 4 can be accurately bonded to the tooth surface 11 of the human body through the separated positioning device 3. Compared with the traditional film pressing method of transferring the bracket 4, the bracket 4 can be transferred without using an adhesive in the embodiment. The embodiment not only simplifies the operation process, reduces the error caused by human operation, and makes the assembly process more convenient. At the same time, the embodiment ensures the rapid bonding and stable positioning of the bracket 4 on the tooth surface 11, thereby ensuring that the bracket 4 can be accurately bonded to the tooth according to the treatment plan, and providing a solid foundation for achieving an ideal treatment effect.

[0037] Optionally, referring to Figure 4 and Figure 5 In an embodiment, the shape of the positioning groove 21 is set as a U shape. The U-shaped structure of the positioning groove 21 is generated by using a 3D modeling technology, and is consistent with the shape and size of the gingival side of the bracket 4. Through the U-shaped structure of the positioning groove 21, the rotation and left-right movement of the bracket 4 after being embedded into the bracket positioning part 2 can be limited.

[0038] Optionally, referring to Figure 4 and Figure 5 In an embodiment, at the bottom area of the positioning groove 21, the conventional suspended structure design concept is abandoned, and the extension is shaped according to the geometric shape trend of the bottom surface of the tooth model. The implementation of this design strategy eliminates the potential risk of failure of the printing process due to the occurrence of undercut in the working process of the 3D printer, significantly improves the success rate of the printing task, and helps to achieve more efficient bracket 4 bonding operation.

[0039] Optionally, referring to Figure 3 In an embodiment, a tooth position identification part 5 is arranged on the end of the positioning device 3 away from the tooth crown 12. Through the tooth position identification part 5, medical personnel can conveniently identify and confirm the tooth position corresponding to the positioning device 3. The bracket 4 on the positioning device 3 is accurately placed on the specified tooth surface 11 in the patient's oral cavity.

[0040] Optionally, referring to Figure 3 In an embodiment, the tooth position identification part 5 can be an identification letter.

[0041] Since the tooth size varies significantly between different individuals, the shape thereof also varies in size, proportion, etc. Therefore, even if the teeth are of the same type, due to these differences, the position of the highest point of the tooth profile will also vary.

[0042] Optionally, referring to Figure 5 In an embodiment, the gingival avoidance groove 22 is arranged at one end of the bracket positioning portion 2 close to the tooth surface 11, so as to avoid the 1 / 4 part of the tip of the bottom of the bracket 4, thereby enhancing the fault tolerance of the tooth positioning model 1 and preventing the bracket 4 from being unable to be correctly positioned in the positioning groove 21 due to the synthetic process problem.

[0043] In the embodiment, the distance between the groove bottom surface of the gingival avoidance groove 22 and the bottom of the bracket clamping portion 31 is less than the distance between the groove bottom surface of the positioning groove 21 and the bottom of the bracket clamping portion 31.

[0044] Optionally, referring to Figure 3 In an embodiment, the two clamping arms 32 are arranged at the mesial side of the bracket clamping portion 31 and the distal side of the bracket clamping portion 31, respectively.

[0045] To this end, optionally, referring to Figure 1 and Figure 2 In an embodiment, the bracket limiting block 13 is arranged on each tooth surface 11, and the bracket 4 is arranged in the bracket limiting block 13. In the embodiment, the bracket limiting block 13 is arranged, which helps the bracket 4 to be stably positioned on the tooth positioning model 1 and avoids the interference of the highest point of the tooth profile, so that the bracket 4 is not subjected to uneven force in the positioning groove 21, thereby preventing the bracket 4 from sliding during the transfer process and causing errors.

[0046] In addition, in addition to the different tooth shapes of patients, in an ideal case, the brackets 4 can be made very similar, but in fact it is difficult to make each one exactly the same, and there will be errors in the manufacturing process. The bracket 4 is usually manufactured by molding or mechanical processing. The mechanical processing equipment itself has certain precision limitations, and in the assembly process of the bracket 4, even if the size of each part is within the design range, but during assembly, the cooperation between the parts may also have slight deviations.

[0047] To this end, optionally, in an embodiment, the distance between the lower end of the bracket limiting block 13 close to the bracket positioning portion 2 and the bottom of the bracket positioning portion 2 is greater than the distance between the bracket 4 close to the bracket positioning portion 2 and the bracket positioning portion 2, that is, the lower end of the bracket limiting block 13 is shorter than the bracket 4. In the embodiment, the bracket limiting block 13 is removed at this part, which can improve the fault tolerance of the tooth positioning model 1 and prevent the bracket 4 from being unable to be correctly positioned in the positioning groove 21 due to the synthetic process problem.

[0048] The part of the bracket limiting block 13 shorter than the bracket 4 can be set as a quarter of the gingival part of the bracket 4.

[0049] Optionally, in an embodiment, the distance between the end of the bracket limiting block 13 away from the tooth surface 11 and the tooth surface 11 is set to 0.3-0.5mm.

[0050] In summary, the orthodontic bracket transfer device provided by the application comprises a tooth positioning model 1, a plurality of bracket positioning parts 2 and a plurality of positioners 3. The tooth positioning model 1 is provided with a plurality of tooth positions, each of which is provided with a tooth surface 11 and a tooth crown 12. The plurality of bracket positioning parts 2 are respectively arranged below the tooth surface 11 of the corresponding tooth position. The top end of the bracket positioning part 2 is provided with a positioning groove 21 corresponding to the gingival part of the bracket 4. The positioning groove 21 is used to initially connect the bracket 4 and stably fix the bracket 4 at the predetermined position. The plurality of positioners 3 are respectively arranged above the corresponding bracket positioning part 2 and are used to be sleeved on the corresponding tooth crown 12. The positioner 3 is provided with a bracket clamping part 31 corresponding to the bracket positioning part 2. The two sides of the bracket clamping part 31 are provided with clamping arms 32. The clamping arms 32 are used to transfer and connect the bracket 4. The bracket 4 is first embedded in the positioning groove 21, and then the positioner 3 is pressed in the direction of the tooth positioning model 1 to embed the bracket 4 in the clamping part and be clamped and fixed by the two clamping arms 32. Since the bracket 4 and the positioning groove 21 are mechanically fixed, and the connection strength between the bracket 4 and the positioner 3 is greater than the connection strength between the bracket 4 and the positioning groove 21, when the positioner 3 and the tooth crown 12 of the tooth positioning model 1 are separated, the bracket 4 on the positioner 3 will be taken away together. The bracket 4 can be accurately bonded to the tooth surface 11 of the human body through the separated positioner 3. The application not only plays an accurate positioning role on the bracket 4, but also simplifies the process of the medical staff assembling the bracket 4 on the tooth model, realizes the transfer of the bracket 4 and the rapid and accurate positioning of the bracket 4 on the tooth.

[0051] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
