Description

Technical Field

[0001] This utility model relates to the field of bracket positioning technology, and in particular to a multifunctional bracket positioner. Background Technology

[0002] In orthodontic clinical practice, the position of brackets directly affects the direction and speed of tooth movement, as well as the final treatment outcome. Therefore, achieving precise bracket bonding is one of the key factors in ensuring the success of orthodontic treatment. Ideally, brackets should be bonded to the midpoint of the tooth in the mesiodistal direction, with their vertical position determined based on the crown height and specific tooth location. However, due to factors such as changes in gingival swelling, the vertical position of the brackets needs to be flexibly adjusted to adapt to different situations.

[0003] Currently, commonly used bracket positioning devices in clinical practice mainly include straight-handle strip bracket positioners and star-shaped bracket positioners. While these tools meet basic needs to some extent, they are insufficient in terms of flexibility and accuracy, especially when adjusting bracket position according to crown height. This limitation complicates clinical procedures and makes them prone to errors, thus affecting treatment outcomes and potentially prolonging treatment time. Many clinicians tend to rely on visual estimation for bracket positioning, but this method is highly susceptible to error.

[0004] In addition, existing bracket locators can only locate the vertical height of the bracket, but cannot accurately locate the center position in the mesiodistal direction. For teeth with rotated crowns or abnormal shapes, finding their center position is a challenge. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing bracket positioner can only locate the vertical height of the bracket, but cannot accurately locate the center position in the near-far-middle direction.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-functional bracket positioner, including a main body, a telescopic component, a first positioning component and a second positioning component, wherein the telescopic component is hinged to the main body;

[0007] The first positioning component includes a first positioning rod, a second positioning rod, and a first driving structure. The first positioning rod and the second positioning rod are arranged opposite to each other on one side of the main body along a first direction to form a first positioning interval. The first positioning rod is installed on the end of the main body away from the telescopic component, and the second positioning rod is slidably installed on the main body through the driving structure.

[0008] The second positioning component includes a third positioning rod, a fourth positioning rod, and a second driving structure. The third positioning rod and the fourth positioning rod are disposed opposite each other on one side of the main body along a second direction, and the third positioning rod and the fourth positioning rod are symmetrically arranged about the first positioning rod as an axis to form a second positioning interval. The second driving structure is installed on the main body and connected to the third positioning rod and the fourth positioning rod to drive the third positioning rod and the fourth positioning rod to move closer or further away from each other. The first direction is perpendicular to the second direction.

[0009] Furthermore, the first driving structure includes a sliding handle and a first locking member. The main body has a first sliding groove on the side facing the second positioning rod, and a second sliding groove communicating with the first sliding groove on the side facing away from the second positioning rod. The sliding handle is slidably installed in the second sliding groove, and the sliding handle passes through the second sliding groove and connects to the second positioning rod to drive the second positioning rod to slide along the first sliding groove. The first locking member can pass through the sliding handle and abut against the bottom of the second sliding groove.

[0010] Furthermore, the first positioning rod has a positioning head at the end opposite to the main body. The positioning head is frustoconical in shape, and the end diameter of the positioning head is 0.4-0.5 mm.

[0011] Furthermore, the second groove has graduations.

[0012] Furthermore, the second driving structure includes a driving member, a bidirectional lead screw, and a guide rod. The main body has a third groove on the side facing the third positioning rod. The bidirectional lead screw and the guide rod are installed at intervals along the length of the third groove. One end of the bidirectional lead screw has a first thread, and the other end of the bidirectional lead screw has a second thread. The first thread and the second thread have opposite thread directions. The third positioning rod is installed at one end of the bidirectional lead screw and is adapted to the first thread. The fourth positioning rod is installed at the other end of the bidirectional lead screw and is adapted to the second thread. The guide rod passes through the third positioning rod and the fourth positioning rod in sequence. The driving member is connected to the bidirectional lead screw to drive the bidirectional lead screw to rotate.

[0013] Furthermore, it also includes a knob and a hinge, the hinge passing through the body and connected to the telescopic assembly, the knob being mounted on the hinge to drive the body to rotate relative to the telescopic assembly.

[0014] Furthermore, the telescopic assembly includes a first telescopic rod, a second telescopic rod, and a second locking member. The second telescopic rod is hinged to the main body, and the end of the second telescopic rod facing away from the main body has a cavity. One end of the first telescopic rod is slidably installed in the cavity, and the second locking member can pass through the second telescopic rod and abut against the outer wall of the first telescopic rod.

[0015] Furthermore, it also includes a cheek screen and a light source, both of which are mounted on the side of the main body away from the second positioning rod, with the light source located on the side of the cheek screen.

[0016] Furthermore, the cheek screen is arc-shaped, with its concave surface facing the side of the main body away from the telescopic component. The convex surface of the cheek screen has a raised structure, and the concave surface of the cheek screen is a mirror surface.

[0017] Furthermore, it also includes a mounting base, which is detachably mounted on the side of the main body away from the second positioning rod, and the cheek screen and the light source are mounted on the mounting base.

[0018] Compared with the prior art, the multifunctional bracket positioner of this utility model has the following advantages:

[0019] This utility model embodiment solves not only the problem of precise vertical positioning of the bracket by providing two independent but complementary positioning intervals, but also the problem of positioning the center position in the mesiodistal direction. For example, for teeth with crown rotation or abnormal shape, more flexible and precise bracket positioning can be achieved by adjusting the positions of the first positioning rod and the second positioning rod, as well as the third positioning rod and the fourth positioning rod, thereby improving the orthodontic effect and reducing the extra treatment time caused by inaccurate positioning.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] like Figure 1 As shown, this utility model provides a multifunctional bracket locator, including a main body 1, a telescopic component 2, a first positioning component 3, and a second positioning component 4. The telescopic component 2 is hinged to the main body 1, making the angle and the length of the main body 1 that can be extended into the oral cavity adjustable, which is convenient for simultaneous use on anterior and posterior teeth, as well as teeth in various quadrants in clinical practice. The first positioning component 3 includes a first positioning rod 31, a second positioning rod 32, and a first driving structure 33. The first positioning rod 31 and the second positioning rod 32 are arranged opposite each other on one side of the main body 1 along a first direction to form a first positioning interval. The first positioning rod 31 is installed at the end of the main body 1 away from the telescopic component 2, and the second positioning rod 32 is slidably installed on the main body 1 through the driving structure. The distance between the second positioning rod 32 and the first positioning rod 32 can be adjusted according to the height of the crown. The length of the bracket is 1, which allows for adjustment of the bracket position; the second positioning component 4 includes a third positioning rod 41, a fourth positioning rod 42, and a second driving structure 43. The third positioning rod 41 and the fourth positioning rod 42 are arranged opposite each other on one side of the main body 1 along the second direction, and the third positioning rod 41 and the fourth positioning rod 42 are symmetrically arranged with the first positioning rod 31 as the axis to form a second positioning interval. The second driving structure 43 is installed on the main body 1 and connected to the third positioning rod 41 and the fourth positioning rod 42 to drive the third positioning rod 41 and the fourth positioning rod 42 to move closer or further away from each other. The relative distance between the third positioning rod 41 and the fourth positioning rod 42 can be adjusted according to the mesiodistal diameter of the crown, so that the first positioning rod 31 is located at the center position of the crown in the mesiodistal direction, and the first direction is perpendicular to the second direction.

[0025] Based on the above structure, this embodiment provides two independent but cooperating positioning intervals, which not only solves the problem of precise positioning of the bracket vertical height, but also solves the problem of positioning the center position in the mesiodistal direction. For example, for teeth with crown rotation or abnormal shape, by adjusting the positions of the first positioning rod 31 and the second positioning rod 32, as well as the third positioning rod 41 and the fourth positioning rod 42, more flexible and precise bracket positioning can be achieved, thereby improving the orthodontic effect and reducing the extra treatment time caused by inaccurate positioning.

[0026] Furthermore, the first drive structure 33 includes a slide handle 331 and a first locking member (not shown in the figure). The main body 1 has a first slide groove 11 on the side facing the second positioning rod 32, and a second slide groove 12 communicating with the first slide groove 11 on the side facing away from the second positioning rod 32. The slide handle 331 is slidably installed in the second slide groove 12, and the slide handle 331 passes through the second slide groove 12 and is connected to the second positioning rod 32 to drive the second positioning rod 32 to slide along the first slide groove 11. The first locking member can pass through the slide handle 331 and abut against the bottom of the second slide groove 12 to lock the position of the slide handle 331, thereby fixing the position of the second positioning rod 32.

[0027] In this embodiment, the position of the second positioning rod 32 is adjusted using the sliding handle 331, thereby adjusting the height of the bracket in the vertical direction. The specific operation is as follows: The doctor can push or pull the sliding handle 331 to slide it along the second sliding groove 12, causing the connected second positioning rod 32 to move synchronously along the first sliding groove 11. Once the correct position is found, a first locking member passes through the sliding handle 331 and abuts against the bottom of the second sliding groove 12 to lock the position of the sliding handle 331, ensuring that the second positioning rod 32 does not move arbitrarily and maintains the set distance unchanged. It should be noted that the adjustable distance between the second positioning rod 32 and the first positioning rod 31 in this embodiment is 2mm-5mm.

[0028] Furthermore, the first positioning rod 31 has a positioning head 311 at the end opposite to the main body 1. The positioning head 311 is frustoconical and has a terminal diameter of 0.4-0.5 mm. Due to its small terminal diameter, it can more accurately point to or contact a specific point on the tooth surface, providing a more precise positioning reference point. At the same time, the small diameter positioning head 311 allows it to adapt to tooth surfaces of different shapes and sizes, especially for teeth with irregular shapes or small sizes.

[0029] Understandably, in some embodiments, the positioning head 311 may also be a prism structure with a pointed end. That is, whether the tip is frustum-shaped or prism-shaped, it is intended to point more accurately at or contact a specific point on the tooth surface, providing a more precise positioning reference point.

[0030] Furthermore, the second slide groove 12 has a scale (not shown in the figure). By observing the position of the slide handle 331 in the second slide groove 12 and its position relative to the scale, the doctor can accurately understand the distance the second positioning rod 32 has moved, providing a specific numerical reference and making it easier for the doctor to record the adjustment parameters.

[0031] Furthermore, the second drive structure 43 includes a drive member 431, a bidirectional lead screw 432, and a guide rod (not shown in the figure). A third groove (not shown in the figure) is formed on the side of the main body 1 facing the third positioning rod 41. The bidirectional lead screw 432 and the guide rod are spaced apart in the third groove along its length. One end of the bidirectional lead screw 432 has a first thread, and the other end has a second thread. The first thread and the second thread have opposite thread directions. The third positioning rod 41 is installed at one end of the bidirectional lead screw 432 and is adapted to the first thread. The fourth positioning rod 42 is installed at the other end of the bidirectional lead screw 432 and is adapted to the second thread, so that when the bidirectional lead screw 432 rotates, the third positioning rod 41 and the fourth positioning rod 42 can move closer or further away from each other to achieve position adjustment in the near-far-middle direction. The guide rod passes through the third positioning rod 41 and the fourth positioning rod 42 in sequence to ensure that the third positioning rod 41 and the fourth positioning rod 42 can only move along the direction of the guide rod and do not rotate with the rotation of the bidirectional lead screw 432. The driving member 431 is connected to the bidirectional lead screw 432 to drive the bidirectional lead screw to rotate.

[0032] Based on the above structure, when the drive component 431 rotates, it will drive the bidirectional lead screw 432 to rotate together. Since the thread directions at both ends of the bidirectional lead screw 432 are opposite, the third positioning rod 41 (which is adapted to the first thread) and the fourth positioning rod 42 (which is adapted to the second thread) will make relative or opposite linear movements along the direction of the guide rod while the bidirectional lead screw 432 rotates. The guide rod passes through the third positioning rod 41 and the fourth positioning rod 42, ensuring that they only move in a straight line, avoiding unnecessary rotation caused by the rotation of the bidirectional lead screw 432, thereby ensuring the stability and accuracy of the positioning process.

[0033] Understandably, the driving component 431 in this embodiment can be a motor connected to the bidirectional lead screw 432. It should be noted that if the motor is located on the side of the main body 1, it can directly drive the rotation of the bidirectional lead screw 432; if the motor is located on the main body 1 and on the same side as the slide 331, a bevel gear can be provided to connect with the motor, and the bidirectional lead screw 432 is provided with a thread that meshes with the bevel gear to drive the bidirectional lead screw 432 to rotate. In some embodiments, the drive member 431 can also be a threaded rod structure. The bidirectional lead screw 432 is also provided with threads that mesh with the threaded rod structure, so that the doctor can manually rotate the threaded rod to control the distance between the third positioning rod 41 and the fourth positioning rod 42, thereby achieving the positioning of the bracket in the mesiodistal direction. This not only improves the flexibility and convenience of operation, but also greatly improves the accuracy of positioning. It is especially suitable for treating teeth with rotated crowns or abnormal shapes. The distance between the third positioning rod 41 and the fourth positioning rod 42 can be adjusted according to the mesiodistal diameter of the crown, so that the third positioning rod 41 and the fourth positioning rod 42 can be placed in the mesiocontact area and the distal contact area of ​​the tooth, respectively, so that the first positioning rod 31 is located at the center position of the crown in the mesiodistal direction.

[0034] Furthermore, it also includes a knob 5 and a hinge (not shown in the figure), the hinge passing through the body 1 and connected to the telescopic assembly 2, and the knob 5 is mounted on the hinge to drive the body 1 to rotate relative to the telescopic assembly 2.

[0035] When the dentist rotates knob 5, it drives the hinge, causing the main body 1 to change angle relative to the telescopic component 2. This allows the dentist to flexibly adjust the angle of the multi-functional bracket locator according to actual needs, better adapting to the operational requirements of teeth in different positions. This embodiment achieves angle adjustment simply by operating knob 5, simplifying the operation process and improving the operational flexibility of the multi-functional bracket locator. It can adapt not only to teeth in different areas such as anterior and posterior teeth, but also conveniently handle teeth in all quadrants of the oral cavity, especially in situations with limited space or difficult-to-reach angles, thus increasing the device's application range.

[0036] Furthermore, the telescopic assembly 2 includes a first telescopic rod 21, a second telescopic rod 22, and a second locking member (not shown in the figure). The second telescopic rod 22 is hinged to the main body 1, and the end of the second telescopic rod 22 away from the main body 1 has a cavity. One end of the first telescopic rod 21 is slidably installed in the cavity. The second locking member can pass through the second telescopic rod 22 and abut against the outer wall of the first telescopic rod 21.

[0037] In this embodiment, by allowing the first telescopic rod 21 to slide within the cavity of the second telescopic rod 22, the dentist can adjust the length of the entire telescopic assembly 2 according to actual needs. This provides convenience for treating teeth of different depths or those that are difficult to reach; for example, a shorter sliding distance is suitable for anterior teeth, while a longer sliding distance is suitable for posterior teeth. Once the length is adjusted to the appropriate position, a second locking member passes through the second telescopic rod 22 and makes tight contact with the outer wall of the first telescopic rod 21 to fix the first telescopic rod 21 in place, preventing further movement and ensuring stability and accuracy during operation. The aforementioned telescopic structure enhances the flexibility and adaptability of the multi-functional bracket locator, allowing dentists to quickly adjust the tool length according to specific situations (such as anterior teeth, posterior teeth, or teeth in different quadrants of the oral cavity), simplifying the operation process and helping to improve treatment efficiency and effectiveness.

[0038] Furthermore, it also includes a buccal shield 6 and a light source 7. Both the buccal shield 6 and the light source 7 are installed on the side of the main body 1 opposite to the second positioning rod 32. The buccal shield 6 can effectively avoid pressure on the buccal mucosa when operating on the posterior teeth, reducing patient discomfort. In addition, the buccal shield 6 can also prevent saliva secreted by the salivary glands from entering the working area, keeping the tooth surface dry. The light source 7 is located on one side of the buccal shield 6 and can directly illuminate the area to be operated on, solving the problem of poor vision caused by insufficient light in the oral cavity, especially in the posterior teeth area, ensuring that the doctor can clearly see every detail, thereby performing more precise operations.

[0039] Furthermore, the buccal shield 6 is arc-shaped, with its concave side facing the main body 1 away from the telescopic component 2. This helps it better adapt to the internal spatial structure of the oral cavity, ensuring that the buccal shield 6 can fit tightly against the patient's oral cavity wall during use, providing stable support and an operating platform. The convex surface of the buccal shield 6 has a raised structure (not shown in the figure), which increases the friction between the buccal shield 6 and the oral cavity tissues, so as to pull the corners of the mouth and the buccal mucosa, thereby providing a clearer and unobstructed operating field of view for the tooth surface and helping to maintain a stable observation angle. The concave surface of the buccal shield 6 is a mirror, which can not only be used as a simple mirror when necessary to help doctors directly observe the status of the bracket position, but also further enhance the visual inspection ability of the working area through reflection, ensuring the accurate positioning of the bracket.

[0040] Preferably, the cheek shield 6 of this embodiment has an ergonomic curvature that effectively isolates saliva produced by the salivary glands while ensuring comfort, thus providing moisture protection and assisting in accurate bracket positioning. Even if the patient bites off the bracket later, a fixed value can be set on the multi-functional bracket locator to ensure that the bracket is adhered to the same position as before during re-adhesion.

[0041] Furthermore, a mounting base (not shown in the figure) is included. This mounting base is detachably mounted on the side of the main body 1 opposite to the second positioning rod 32, increasing the flexibility and versatility of the device and allowing for quick replacement or adjustment of components such as the buccal screen 6 and the light source 7 according to different clinical needs. For example, when the buccal screen 6 and the light source 7 are not needed, the mounting base can be easily removed to reduce weight or change operating characteristics; or it can be quickly installed when required to adapt to specific operational requirements. The mounting of the buccal screen 6 and the light source 7 onto the mounting base simplifies the overall structure of the device and improves ease of use.

[0042] In summary, this utility model embodiment provides a multifunctional bracket locator. The main body 1 has an adjustable angle and length, facilitating simultaneous use on anterior and posterior teeth, as well as teeth in various quadrants, in clinical practice. The distance between the second positioning rod 32 and the first positioning rod 31 can be flexibly adjusted to facilitate bracket positioning. Furthermore, it allows for more precise positioning between the mesial and distal ends, resulting in more accurate bracket placement. The buccal shield 6 serves as a moisture barrier while also pulling the corners of the mouth; its concave surface can also function as a mouth mirror, offering multiple uses and improving efficiency. Combined with the light source 7, it provides supplementary illumination, resulting in a clearer operating field of view.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
