Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary instruments for orthodontic treatment, and specifically relates to an orthodontic archwire auxiliary molding device. Background Technology

[0002] With increasing public awareness of cosmetic dentistry, orthodontic treatment is becoming more and more common. However, archwire correction is the most frequently used method in orthodontic procedures. There are two main types of archwires: round and square. Square archwires are used in the later stages of orthodontic treatment. Square archwire correction often requires torque force to correct teeth, and this torque force requires a specific torque angle. Currently, clinicians often use torque clamps to manipulate the torque angle of square archwires. However, the torque angle created with torque clamps is highly dependent on the clinician's experience. Clinicians with extensive experience are required to accurately create the necessary torque angle on the archwire, making it difficult for inexperienced clinicians to perform the torque manipulation independently. Therefore, to address these issues, we propose an orthodontic archwire shaping aid device. Summary of the Invention

[0003] To overcome the problems existing in related technologies, the present invention discloses an orthodontic archwire-assisted molding device.

[0004] To achieve the above objectives, one technical solution adopted by the present invention is:

[0005] An orthodontic archwire-assisted shaping device includes a measuring plate and a shaping component. The measuring plate has a placement groove on its front side and a through hole at the bottom of the placement groove for the square wire to pass through.

[0006] The molding component includes a fixed molding part that can be assembled into a placement groove. The fixed molding part has a circular groove at its front end, a first square thread hole coaxially arranged at the bottom of the circular groove, and an internal thread groove at the front of the side wall of the circular groove.

[0007] The molding assembly further includes a movable molding component, which includes a cylinder with a diameter matching the diameter of the circular groove. The rear end of the cylinder has a circular plate with the same outer diameter. The circular plate has a second square thread hole corresponding to the first square thread hole. The side of the cylinder has an external thread strip that matches the internal thread groove. There is a gap between the rear end of the external thread strip and the rear end of the circular plate. The side of the cylinder has a scale indicator structure.

[0008] Furthermore, the front end of the circular plate is provided with a transverse sliding groove located above and communicating with the second square wire hole, and the top wall of the transverse sliding groove is provided with a vertical sliding groove penetrating the upper end of the circular plate, and the vertical sliding groove is located on the rear side of the external threaded strip;

[0009] The moving part further includes a sliding part and an elastic part. The sliding part includes a horizontal plate that is longitudinally slidably assembled in the horizontal sliding groove, a vertical plate that is longitudinally slidably assembled in the vertical sliding groove and fixed to the horizontal plate, and a pressure block provided at the lower end of the horizontal plate and matching the second square wire hole.

[0010] The elastic element is located between the upper end of the horizontal plate and the inner top wall of the cylinder. When the pressure block abuts against the bottom wall of the second square wire hole, the upper end of the vertical plate will be aligned with the side of the circular plate.

[0011] Furthermore, the elastic element is a helical spring, and the upper and lower ends of the helical spring abut against the inner top wall of the cylinder and the upper end of the horizontal plate, respectively.

[0012] Furthermore, the inner top wall of the cylinder and the upper end of the horizontal plate are respectively provided with an upper sleeve and a lower sleeve for covering the upper and lower sides of the helical spring.

[0013] Furthermore, the cylinder is composed of two parts joined together, with the joint surface of the two parts located between the upper and lower walls of the transverse sliding groove.

[0014] Furthermore, the connection between the two parts of the cylinder is a detachable fixed connection.

[0015] Furthermore, the two parts of the cylinder are fixed together by multiple screws.

[0016] Furthermore, the rear end face of the pressure block is an inclined surface that slopes from front to back and from bottom to top.

[0017] Furthermore, the outer contour of the placement groove is a regular hexagon, and the outer contour of the molded part is a regular hexagon that matches the placement groove.

[0018] Furthermore, a base is fixedly connected to the lower end of the measuring disk, and the measuring disk is perpendicularly connected to the base.

[0019] In summary, this invention discloses an orthodontic archwire-assisted shaping device that assists doctors in performing high-precision torsion shaping of the archwire. Thus, regardless of experience level, clinicians can easily shape the required torque angle on the archwire, thereby improving the orthodontic effect. Attached Figure Description

[0029] Measuring disc 1, placement groove 11, through hole 12, base 13, forming component 2, fixed forming part 21, circular groove 211, first square wire hole 212, internal thread groove 213, moving forming part 22, cylinder 221, circular plate 2211, second square wire hole 2212, external thread strip 2213, scale indicator structure 2214, horizontal sliding groove 2215, vertical sliding groove 2216, sliding part 222, horizontal plate 2221, vertical plate 2222, pressure block 2223, elastic part 223, square wire 3. Detailed Implementation

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] Reference Figure 1-7 As shown, the orthodontic archwire-assisted shaping device of the present invention includes a measuring plate 1 and a shaping component 2. A placement groove 11 is provided on the front side of the measuring plate 1. The outer contour of the placement groove 11 is a regular hexagon. A through hole 12 for the square wire 3 to pass through is provided at the bottom of the placement groove 11. The diameter of the through hole 12 is 5 mm or more. A base 13 is fixedly connected to the lower end of the measuring plate 1. The measuring plate 1 and the base 13 are vertically connected, and the measuring plate 1 can be placed upright on a table via the base 13.

[0032] The molding assembly 2 includes a fixed molding component 21 that can be assembled into the placement groove 11. The outer contour of the fixed molding component 21 is a regular hexagon that matches the placement groove 11. After the fixed molding component 21 is assembled into the placement groove 11, the fixed molding component 21 and the measuring disk 1 will not rotate relative to each other. It is worth mentioning that the fixed molding component 21 can be directly inserted into the placement groove 11 and fixed by mutual friction, or a magnet can be set at the bottom of the placement groove 11 and the fixed molding component 21 can be made of magnetic metal, so that it can also be fixed by magnetic adsorption.

[0033] The front end of the molded part 21 has a circular groove 211, and the front part of the side wall of the circular groove 211 has an internal thread groove 213. The bottom of the circular groove 211 has a coaxially arranged first square wire hole 212, which is used to insert a square wire 3. After the square wire 3 is inserted into the first square wire hole 212, the first square wire hole 212 will restrict the square wire 3 from rotating relative to the molded part 21.

[0034] The molding component 2 also includes a movable molding part 22, which includes a cylinder 221. The diameter of the cylinder 221 matches the diameter of the circular groove 211, so that the cylinder 221 can be inserted into the circular groove 211 and form a sleeve connection with the circular groove 211.

[0035] The rear end of the cylinder 221 has a circular plate 2211 with the same outer diameter. The circular plate 2211 has a second square wire hole 2212 corresponding to the first square wire hole 212. The second square wire hole 2212 is used to insert the square wire 3. After the square wire 3 is inserted into the second square wire hole 2212, the second square wire hole 2212 will restrict the square wire 3 from rotating relative to the circular plate 2211.

[0036] The side of the cylinder 221 has an external threaded bar 2213 that matches the internal threaded groove 213. There is a gap between the rear end of the external threaded bar 2213 and the rear end of the circular plate 2211. The external threaded bar 2213 can be screwed into the internal threaded groove 213 to form a threaded connection with the internal threaded groove 213.

[0037] The cylinder 221 has a scale indicator structure 2214 on its side. The scale indicator structure 2214 can indicate the angle of the cylinder 221 on the measuring disk 1 so that the user can understand the rotation angle of the cylinder 221.

[0038] When twisting the square wire 3, insert one end of the square wire 3 into the second square wire hole 2212 and keep the position to be twisted behind the second square wire hole 2212. Then insert the other end of the square wire 3 into the first square wire hole 212. When inserting the square wire 3, it needs to be moved together with the cylinder 221. After the circular plate 2211 at the rear end of the cylinder 221 is inserted into the circular groove 211, the cylinder 221 can be rotated to twist the square wire 3. Since the circular plate 2211 will form a nesting relationship when it enters the circular groove 211 and the diameters of the two match, the circular plate 2211 will rotate coaxially with the circular groove 211 when it rotates. This can prevent the front and rear sides of the square wire 3 from bending and keep it coaxially twisted.

[0039] It is worth mentioning that the scale indicator structure 2214 will make corresponding indications on the measuring plate 1 as the cylinder 221 rotates, so that the user can know the specific torsion angle of the square wire 3. Thus, regardless of whether the clinician is experienced or not, they can easily form the required torque angle on the square wire 3, thereby improving the orthodontic effect.

[0040] Since the cross-sectional dimensions of the square wire 3 are not unique, different sizes of square wire 3 will be twisted in actual work. This invention can address this problem in the following way: Specifically, multiple sets of forming components 2 are set up, and the first square wire hole 212 and the second square wire hole 2212 of each set of forming components 2 are set according to different sizes of the method 3. In this way, when twisting square wire 3 of different sizes, the corresponding fixed forming part 21 can be selected and inserted into the placement groove 11, and then the corresponding moving forming part 22 is used to twist the square wire 3. In this way, square wire 3 of multiple sizes can be twisted. It is worth mentioning that when the fixed forming part 21 is taken out from the placement groove 11, the external thread strip 2213 of the moving forming part 22 can be screwed into the internal thread groove 213 of the fixed forming part 21, so that the two sides are connected together. In this way, the fixed forming part 21 can be pulled out by the moving forming part 22.

[0041] It is worth mentioning that when storing the molding component 2, since the moving molding part 22 and the fixed molding part 21 can be threaded together, the two can be stored together to reduce the probability of losing a single part. In addition, when the fixed molding part 21 is pulled out, the fixed molding part 21 is connected to the moving molding part 22, so there is no need to perform any additional connection operation.

[0042] To further improve the convenience of the torsion operation, the following settings are made in this embodiment: Specifically, a horizontal sliding groove 2215 is provided at the front end of the circular plate 2211, which is located above and communicates with the second square wire hole 2212. A vertical sliding groove 2216 is provided on the top wall of the horizontal sliding groove 2215, which penetrates the upper end of the circular plate 2211. The vertical sliding groove 2216 is located on the rear side of the external threaded strip 2213.

[0043] The moving part 22 also includes a sliding part 222 and an elastic part 223. The sliding part 222 includes a horizontal plate 2221 that is longitudinally slidably assembled in the horizontal slide groove 2215, a vertical plate 2222 that is longitudinally slidably assembled in the vertical slide groove 2216 and fixed to the horizontal plate 2221, and a pressure block 2223 that is located at the lower end of the horizontal plate 2221 and matches the second square wire hole 2212.

[0044] In this embodiment, the elastic element 223 is a helical spring, and the upper and lower ends of the helical spring abut against the inner top wall of the cylinder 221 and the upper end of the horizontal plate 2221, respectively. In addition, the inner top wall of the cylinder 221 and the upper end of the horizontal plate 2221 are respectively provided with an upper sleeve and a lower sleeve for covering the upper and lower sides of the helical spring, which can stabilize the position of the helical spring.

[0045] In its natural state, the elastic element 223 will push the horizontal plate 2221 downward under its own elastic force, in conjunction with the cylinder 221, so that the pressure block 2223 abuts against the bottom wall of the second square thread hole 2212. In this state, the upper end of the vertical plate 2222 will be aligned with the side of the circular plate 2211, that is, the vertical plate 2222 will not protrude from the side of the circular plate 2211. In this state, the circular plate 2211 can smoothly enter the circular groove 211, and the external thread strip 2213 on the side of the cylinder 221 can be directly threaded to the internal thread groove 213.

[0046] When twisting the square wire 3, the horizontal plate 2221 is pushed upwards, causing the pressure block 2223 to disengage from the second square wire hole 2212, making room for the insertion of the square wire 3. The square wire 3 can then be inserted into the second square wire hole 2212. After insertion, the horizontal plate 2221 is released, and the elastic element 223 rebounds, pushing the horizontal plate 2221 and causing the pressure block 2223 to move downwards, clamping the square wire 3 and achieving automatic fixation. This eliminates the need for the user to hold the square wire 3 when moving and rotating the moving forming part 22, reducing operational difficulty. When adjusting the specific twist position of the square wire 3, it can be pulled relative to the moving forming part 22. The user's pulling action overcomes the clamping force of the pressure block 2223, allowing adjustment of the axial position of the square wire 3.

[0047] It is worth mentioning that after the pressure block 2223 clamps the square wire 3, the pressure block 2223 will be raised by the square wire 3, and the vertical plate 2222 located at the upper end of the horizontal plate 2221 will extend out of the upper end of the vertical slide groove 2216, that is, extend out from the side of the round plate 2211. Thus, when the round plate 2211 is inserted into the round groove 211, its insertion depth will be limited by the vertical plate 2222. That is, the rear end of the vertical plate 2222 will abut against the front end of the fixed forming part 21 or the front end of the measuring plate 1. Since the vertical plate 2222 is located behind the external thread strip 2213, when the moving forming part 22 is inserted into the round groove 211 for twisting operation, the protruding vertical plate 2222 can prevent the external thread strip 2213 from being threadedly connected to the internal thread groove 213. Thus, when the user twists the moving forming part 22, there is no need to deliberately control the axial position between the moving forming part 22 and the round groove 211, which further reduces the difficulty of the twisting operation.

[0048] It should be emphasized that the extension state of the vertical plate 2222 will automatically change depending on whether the square wire 3 is inserted, without the need for the user to make any special adjustments.

[0049] In this embodiment, the rear end face of the pressure block 2223 is an inclined surface that slopes from front to back and from bottom to top. Thus, the square wire 3 can be directly inserted through the second square wire hole 2212. After the front end of the square wire 3 contacts the inclined surface of the rear end of the pressure block 2223, it can push the pressure block 2223 upwards under the guiding action of the inclined surface, allowing the pressure block 2223 to automatically move aside. This eliminates the need for the user to deliberately lift the horizontal plate 2221, further reducing the number of operation steps.

[0050] In addition, in this embodiment, the cylinder 221 is composed of two parts spliced ​​together. The two parts of the cylinder 221 are fixed together by multiple screws. The splicing surface of the two parts of the cylinder 221 is located between the upper and lower walls of the horizontal sliding groove 2215, so as to assemble the sliding part 222. This design also facilitates the fabrication of the horizontal plate 2221, the vertical plate 2222 and the pressure block 2223 into an integral structure to improve its strength.

[0051] In summary, this invention discloses an orthodontic archwire-assisted shaping device that assists doctors in performing high-precision torsion shaping of the archwire. Thus, regardless of experience level, clinicians can easily shape the required torque angle on the archwire, thereby improving the orthodontic effect.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
