Description

Technical Field

[0001] This utility model belongs to the field of orthodontic technology, and specifically relates to a device for correcting fine wire arch differential. Background Technology

[0002] The fine-wire archwire is the core component of the Begg orthodontic technique. Since its inception, the fine-wire orthodontic technique has become the cornerstone of efficient orthodontic treatment due to its differential force effect. This technique uses a fine-diameter archwire to apply light and continuous force, causing single-rooted anterior teeth to move preferentially, while multi-rooted posterior teeth remain stable due to their large periodontal ligament area, thus achieving "selective tooth movement".

[0003] Classical theory states that "anterior tooth movement force ≤ 60g, posterior tooth movement force ≥ 200g", but in reality, it is affected by root morphology (length / firtation), bone density, age, and periodontal health, resulting in significant individual differences. In current clinical practice, doctors can only indirectly estimate the force value through tactile experience, conversion of elastic band stretching length, and trial-and-error follow-up visits for adjustment. Obtaining force value data is cumbersome and not intuitive enough. Utility Model Content

[0004] To address the problem that due to significant individual differences, doctors can only indirectly estimate force values ​​through tactile experience, elastic band stretching length conversion, and trial-and-error follow-up adjustments, making force value data acquisition cumbersome and not intuitive, this invention proposes a device for correcting differential wire bows to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a device for correcting differential motion of a fine wire arch, including a base. The top of the base is provided with a limiting component, a dental mold, an adjustment component, and a detection component. The limiting component and the detection component are respectively located on both sides of the dental mold. The limiting component is used to limit and fix the dental mold. The adjustment component is used to adjust the position of the detection component. The detection component is used to detect the differential force applied by the fine wire arch to the dental mold.

[0007] Furthermore, the limiting component includes a first screw, which is rotatably connected to the top of the base. A pressure plate is threadedly connected to the outer surface of the first screw, and a first nut is fixedly connected to the upper end of the first screw. A guide rod is slidably connected to the outer surface of the pressure plate, and the lower end of the guide rod is fixedly connected to the base. A limiting plate is fixedly connected to the upper end of the guide rod.

[0008] Furthermore, the adjusting assembly includes a second screw, which is rotatably connected to the top of the base. A second cap is fixedly connected to the upper end of the second screw. A movable seat is threadedly connected to the outer surface of the second screw. A sliding plate is fixedly connected to the bottom of the movable seat. A square plate is fixedly connected to the bottom of the sliding plate. A fixed seat is slidably connected to the outer surfaces of the sliding plate and the square plate. The fixed seat is fixedly connected to the top of the base. Both the sliding plate and the square plate are slidably connected inside the fixed seat.

[0009] Furthermore, the detection component includes a miniature push rod, which is fixedly connected to the outer surface of the movable base.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects a limiting component and a detection component. After the limiting component fixes the patient's dental model on the top of the base, the limiting component and the detection component are located on both sides of the dental model to avoid the limiting component obstructing the detection component.

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a device for correcting differential force of a fine wire arch, including a base 1. The top of the base 1 is provided with a limiting component 2, a dental mold 3, an adjusting component 4, and a detection component 5. The limiting component 2 and the detection component 5 are respectively located on both sides of the dental mold 3. The limiting component 2 is used to limit and fix the dental mold 3. The adjusting component 4 is used to adjust the position of the detection component 5. The detection component 5 is used to detect the differential force applied by the fine wire arch to the dental mold 3.

[0029] First, a CBCT scan of the patient's oral cavity is performed to extract the surface area and bone density of the tooth roots and calculate the resistance coefficient. Then, a 3D-printed dental mold 3 is made. The hardness of the silicone periodontal ligament is matched according to the resistance coefficient. After the dental mold 3 is placed on top of the base 1, the limiting component 2 on the top of the base 1 moves downward to limit and fix the dental mold 3. Then, the adjusting component 4 drives the detection component 5 to move on the outer surface of the base 1 so that the height of the detection component 5 matches that of the dental mold 3. Then, the detection component 5 contacts the dental mold 3, and the fine wire arch is installed on the outer surface of the dental mold 3. The six-dimensional force sensor in the detection component 5 monitors the force and torque on the teeth in three-dimensional space in real time, and the tooth movement trajectory is recorded by the laser displacement sensor, which makes it easier for the doctor to adjust the differential force of the fine wire arch according to the patient's own situation.

[0030] This invention connects the limiting component 2 and the detection component 5. After the limiting component 2 fixes the patient's dental mold 3 to the top of the base 1, the limiting component 2 and the detection component 5 are located on both sides of the dental mold 3, avoiding obstruction of the detection component 5 by the limiting component 2. Then, the detection component 5 approaches the dental mold 3. When the fine wire arch applies differential force to the dental mold 3, the dental mold 3 moves. The detection component 5 detects and records the force and displacement data of the dental mold 3, which makes it convenient for doctors to adjust the fine wire arch according to the actual situation of the patient. It is more convenient to use.

[0031] In one embodiment, the limiting component 2 includes a first screw 201, which is rotatably connected to the top of the base 1. A pressure plate 202 is threadedly connected to the outer surface of the first screw 201. A first cap 203 is fixedly connected to the upper end of the first screw 201. A guide rod 204 is slidably connected to the outer surface of the pressure plate 202. The lower end of the guide rod 204 is fixedly connected to the base 1. A limiting plate 205 is fixedly connected to the upper end of the guide rod 204.

[0032] Rotate the first screw cap 203, which drives the first screw 201 to rotate on the top of the base 1. The rotational tendency of the pressure plate 202 on the outer surface of the first screw 201 is blocked by the guide rod 204. At this time, the first screw 201 can drive the pressure plate 202 to slide along the guide rod 204. After the pressure plate 202 separates from the base 1, place the dental mold 3 between the pressure plate 202 and the base 1. Reverse the first screw 201 to drive the pressure plate 202 down to fix the dental mold 3 on the top of the base 1, so as to avoid unnecessary movement of the dental mold 3.

[0033] In one embodiment, the adjustment component 4 includes a second screw 401 rotatably connected to the top of the base 1. A second cap 402 is fixedly connected to the upper end of the second screw 401. A movable seat 403 is threadedly connected to the outer surface of the second screw 401. A sliding plate 404 is fixedly connected to the bottom of the movable seat 403. A square plate 405 is fixedly connected to the bottom of the sliding plate 404. A fixed seat 406 is slidably connected to the outer surfaces of the sliding plate 404 and the square plate 405. The fixed seat 406 is fixedly connected to the top of the base 1. Both the sliding plate 404 and the square plate 405 are slidably connected inside the fixed seat 406.

[0034] Rotating the second cap 402 causes the second screw 401 to rotate. The rotational tendency of the movable seat 403 on the outer surface of the second screw 401 is blocked by the sliding plate 404 and the fixed seat 406. At this time, the second screw 401 can drive the movable seat 403 to move the sliding plate 404 and the square plate 405, thereby adjusting the height of the movable seat 403. The square plate 405 can only slide inside the fixed seat 406, which can limit the movement distance of the movable seat 403.

[0035] In one embodiment, the detection component 5 includes a miniature push rod 501, which is fixedly connected to the outer surface of the movable base 403. A connecting plate 502 is fixedly connected to the movable end of the miniature push rod 501. A bolt 503 is threadedly connected to the outer surface of the connecting plate 502. A connecting seat 504 is fixedly connected to the connecting plate 502 by the bolt 503. A flexible strip 505 is fixedly connected inside the connecting seat 504. Multiple sets of miniature sensors 506 are fixedly installed inside the flexible strip 505.

[0036] The miniature pusher 501 drives the flexible strip 505 to move along with the moving seat 403. When the miniature pusher 501 is activated, the movable end of the miniature pusher 501 pushes the connecting seat 504 and the flexible strip 505 to move, so that the flexible strip 505 fits the dental mold 3. At this time, the data of the six-dimensional force sensor in the miniature sensor 506 is recorded as 0. After the wire arch is installed on the dental mold 3, the wire arch applies force to the dental mold 3 to make it move. The six-dimensional force sensor in the miniature sensor 506 monitors the force and torque on the teeth in three-dimensional space in real time, and the tooth movement trajectory is recorded by the laser displacement sensor, which makes it convenient for doctors to adjust the differential force of the wire arch according to the patient's own situation.

[0037] In one embodiment, for the base 1, a fixing plate 6 is fixedly connected to the top of the base 1, a first bent plate 7 is fixedly connected to the outer surface of the fixing plate 6, a pin 8 is rotatably connected to the outer surface of the first bent plate 7, a second bent plate 9 is rotatably connected to the outer surface of the pin 8, and a cover plate 10 is fixedly connected to the outer surface of the second bent plate 9.

[0038] In one embodiment, the outer surface of the cover plate 10 is fixedly connected to a handle 11.

[0039] Pushing the handle 11 causes the cover plate 10 to rotate around the pin 8, so that the cover plate 10 is engaged with the fixed plate 6. At this time, the cover plate 10 can protect the internal components.

[0040] In one embodiment, the bottom of the fixing plate 6 is fixedly connected with an anti-slip pad 12.

[0041] There are multiple sets of anti-slip pads 12, symmetrically distributed on the bottom of the fixing plate 6.

[0042] Through the above technical solution, 1. By connecting the limiting component 2 and the detection component 5, after the limiting component 2 fixes the patient's dental mold 3 on the top of the base 1, the limiting component 2 and the detection component 5 are located on both sides of the dental mold 3, avoiding obstruction of the detection component 5 by the limiting component 2. Subsequently, the detection component 5 approaches the dental mold 3. When the wire arch applies differential force to the dental mold 3, the dental mold 3 moves. The detection component 5 detects and records the force and displacement data of the dental mold 3, which is convenient for doctors to adjust the wire arch according to the actual situation of the patient, making it more convenient to use; 2. By connecting the micro push rod 501 and the moving seat 403, when the second screw 401 is rotated to drive the moving seat 403 to move up and down, the micro push rod 501 located on the outer surface of the base 403 drives the micro sensor 506 to move up and down with the moving seat 403, adjusting the micro sensor 506 to the same height as the dental mold 3, reducing the error caused by the difference in height, and improving the accuracy of the detection.
