Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral medical device technology, specifically to a safe enamel removal tool. Background Technology
[0002] Interproximal enamel removal, also known as "interproximal reduction," is a common technique in orthodontic treatment. Its purpose is to use appropriate instruments to remove a certain amount of enamel from the interproximal surfaces of teeth, reducing the mesiodistal width and providing space for crowded teeth, thus reducing the likelihood of extraction. When performing interproximal enamel removal, it is crucial to carefully control the amount and location of enamel removal to prevent damage to the tooth's shape and structure. In clinical practice, using enamel removal tools with sandpaper is a relatively safe method.
[0003] An existing type of adjacent-face glaze removal structure, such as Figure 1 As shown, it includes a first retaining frame 1 and a second retaining frame 2. A connecting strip 11 is fixed to the top of the first retaining frame 1, and a connecting groove is provided on the top of the second retaining frame 2. The connecting strip 11 can be slidably inserted into the connecting groove to form an arc-shaped retaining frame. A stud 3 is fixedly connected to the inner side of the second retaining frame 2. A knob 4 is threaded onto the stud 3. The knob 4 can be rotated on the stud 3 until it abuts against the first retaining frame 1. A first slot is provided at the bottom of the first retaining frame 1, and a second slot is provided at the bottom of the second retaining frame 2. A sanding strip 5 is clamped in the first slot and the second slot. A first clamp 6 is hinged to the frame of the first retaining frame 1. The first clamp 6 is suitable for clamping one end of the sanding strip 5 located at the bottom of the first retaining frame 1. A second clamp 7 is hinged to the frame of the second retaining frame 2. The second clamp 7 is suitable for clamping the other end of the sanding strip 5 located at the bottom of the second retaining frame 2. In use, first rotate knob 4 on stud 3 until it contacts and abuts against the first retainer 1, thereby taut and straightening the abrasive strip 5, which is locked in the first and second slots. Then, hold the entire interproximal enamel remover firmly by hand, and press the abrasive strip 5 into the interdental space and move it repeatedly. The abrasive strip 5 removes a certain amount of enamel from the interproximal surface of the tooth. This process requires precise control of the amount removed to avoid excessive damage to the tooth. However, the inventors of this application found through clinical use that when removing enamel from the interproximal surface using the abrasive strip 5, in most cases, the abrasive strip 5 inevitably touches the edge of the gingival papilla, causing bleeding during enamel removal and causing some damage to the patient. Utility Model Content
[0004] In response to the technical problem that existing proximal enamel removers often cause bleeding during enamel removal by inevitably touching the edge of the gingival papilla with abrasive strips, this invention provides a safe enamel removal tool.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A safe glaze removal tool includes a first retaining frame and a second retaining frame. A connecting strip is fixed to the top of the first retaining frame, and a connecting groove is formed on the top of the second retaining frame. The connecting strip can be slidably inserted into the connecting groove to form an arc-shaped retaining frame. A stud is fixedly connected to the inner side of the second retaining frame, and a knob is threaded onto the stud. The knob can be rotated on the stud until it abuts against the first retaining frame. A first locking groove is provided at the bottom of the first retaining frame, and a second retaining frame has a... The second retainer has a sanding strip inserted into the first and second retainers. A first clamp is hinged to the frame of the first retainer, which is adapted to clamp one end of the sanding strip located at the bottom of the first retainer. A second clamp is hinged to the frame of the second retainer, which is adapted to clamp the other end of the sanding strip located at the bottom of the second retainer. A support plate is vertically fixed to the top side of the second retainer. A lifting rod is connected to the outer end of the support plate. A contact plate suitable for contacting the surface of the crown is connected to the lower end of the lifting rod.
[0007] Compared with the prior art, the safe enamel removal tool provided by this utility model can adjust the distance between the bottom surface of the contact plate and the bottom edge of the abrasive strip by raising and lowering the lifting rod. This distance is slightly smaller than the predicted vertical distance from the bottom surface of the contact plate to the top of the gingival papilla. As a result, when the enamel on the proximal surface of the tooth is removed by the abrasive strip, the bottom surface of the contact plate will first contact the surface of the tooth crown, preventing the abrasive strip from extending further towards the gum line and avoiding bleeding caused by the abrasive strip hitting the edge of the gingival papilla. This effectively improves the safety of enamel removal on the proximal surface of the tooth.
[0008] Furthermore, the outer end of the support plate is provided with a threaded hole, and the lifting vertical rod is connected to the threaded hole through the external thread on its surface. The lower end of the lifting vertical rod is rotatably connected to the touch plate, and the length of the touch plate is greater than the distance between the bottom of the first fixing frame and the second fixing frame.
[0009] Furthermore, the lower end surface of the lifting rod is provided with a flange, and the surface of the contact plate is provided with an inverted T-shaped sleeve. The lower end of the lifting rod is rotatably connected to the inverted T-shaped sleeve through the flange.
[0010] Furthermore, a handle larger than the diameter of the lifting rod is fixedly provided at the upper end of the lifting rod.
[0011] Furthermore, the first or second retaining frame is provided with a depth scale.
[0012] Furthermore, the top side of the second retainer is provided with a holding rod that can extend out of the mouth. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0019] In the description of this utility model, it should 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Please refer to Figure 2As shown, this utility model provides a safe glaze removal tool, including a first retaining frame 1 and a second retaining frame 2. A connecting strip 11 is fixed to the top of the first retaining frame 1, and a connecting groove is formed on the top of the second retaining frame 2. The connecting strip 11 can be slidably inserted into the connecting groove to form an arc-shaped retaining frame. A stud 3 is fixedly connected to the inner side of the second retaining frame 2, and a knob 4 is threaded onto the stud 3. The knob 4 can be rotated on the stud 3 until it abuts against the first retaining frame 1. A first locking groove is provided at the bottom of the first retaining frame 1, and a second locking groove is provided at the bottom of the second retaining frame 2. Abrasive strips 5 are fitted into the first and second slots. The abrasive strips 5 can be made of existing diamond abrasive strips or plastic abrasive strips. A first clamping sleeve 6 is hinged to the frame of the first retention frame 1. The first clamping sleeve 6 is adapted to clamp one end of the abrasive strip 5 located at the bottom of the first retention frame 1. A second clamping sleeve 7 is hinged to the frame of the second retention frame 2. The second clamping sleeve 7 is adapted to clamp the other end of the abrasive strip 5 located at the bottom of the second retention frame 2. A support plate 8 is vertically fixed to the top side of the second retention frame 2. A lifting vertical rod 9 is connected to the outer end of the support plate 8. A contact plate 10 suitable for contacting the surface of the tooth crown is connected to the lower end of the lifting vertical rod 9.
[0021] Compared with the prior art, the safe enamel removal tool provided by this utility model can adjust the distance between the bottom surface of the contact plate and the bottom edge of the abrasive strip by raising and lowering the lifting rod. This distance is slightly smaller than the predicted vertical distance from the bottom surface of the contact plate to the top of the gingival papilla. As a result, when the enamel on the proximal surface of the tooth is removed by the abrasive strip, the bottom surface of the contact plate will first contact the surface of the tooth crown, preventing the abrasive strip from extending further towards the gum line and avoiding bleeding caused by the abrasive strip hitting the edge of the gingival papilla. This effectively improves the safety of enamel removal on the proximal surface of the tooth.
[0022] In a specific embodiment, the outer end of the support plate 8 is provided with a threaded hole, and the lifting rod 9 is connected to the threaded hole through the external thread on its surface. That is, the support plate 8 and the lifting rod 9 are connected by threads, so that the lifting rod 9 can be manually rotated to adjust its height. The lower end of the lifting rod 9 is rotatably connected to the touch plate 10, and the length of the touch plate 10 is greater than the distance between the bottom of the first retention frame 1 and the second retention frame 2. Therefore, during the process of manually rotating the lifting rod 9 to adjust its height, the touch plate 10 can be prevented from rotating with the lifting rod 9, ensuring that the length direction of the touch plate 10 is consistent with the length direction of the sanding strip 5, so that the bottom surface of the touch plate can contact and press against the crown surface along the length direction of the sanding strip 5.
[0023] For a specific embodiment, please refer to Figure 3As shown, the lower end surface of the lifting rod 9 is provided with a flange 91, and the surface of the contact plate 10 is provided with an inverted T-shaped sleeve 101. The lower end of the lifting rod 9 is rotatably connected to the inverted T-shaped sleeve 101 through the engagement of the flange 91. That is, by fitting the flange 91 onto the lower part of the inverted T-shaped sleeve 101, the lower end of the lifting rod 9 and the contact plate 10 can be rotatably connected. Preferably, ball bearings can also be provided between the edge of the flange 91 and the inverted T-shaped sleeve 101 to improve the smoothness of rotation. Of course, those skilled in the art can also use bearings or other methods to achieve the rotatable connection based on the foregoing embodiments.
[0024] For a specific embodiment, please refer to Figure 2 As shown, the upper end of the lifting rod 9 is fixed with a handle 92 that is larger than the diameter of the lifting rod 9, so that it is easy to hold the handle 92 to rotate the lifting rod 9 to achieve lifting and adjusting.
[0025] For a specific embodiment, please refer to Figure 2 As shown, the first retaining frame 1 or the second retaining frame 2 is provided with a depth scale 12. Thus, during the lifting and lowering process of the rotating adjustment lifting rod 9, the distance between the bottom surface of the touch plate 10 and the bottom edge of the sanding strip can be accurately determined by observing the depth scale 12 opposite to the bottom surface of the touch plate 10. This is the predicted depth of glaze removal on the adjacent surface, which is convenient and quick.
[0026] For a specific embodiment, please refer to Figure 2 As shown, the top side of the second retainer 2 is provided with a holding rod 13 that can extend outside the mouth. The holding rod 13 can be fixedly set parallel or perpendicular to the top side of the second retainer 2. Thus, the entire glaze removal tool can be held by the holding rod 13 for grinding operation, which is time-saving, labor-saving and very convenient.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
