Description

Technical Field

[0001] The utility model relates to the technical field of occlusal inducers, in particular to a silicone occlusal inducer with an extraoral bow. Background Art

[0002] The extraoral arch bite inducer is a commonly used orthodontic device in oral correction. It mainly solves problems such as malocclusion by adjusting the force between the upper and lower jaws.

[0003] For example, the patent number CN221106074U discloses a high-position traction type dental correction device. Although the high-position traction type dental correction device is provided with two vertical extraoral bows, so that the traction force of the two vertical extraoral bows can not only inhibit the growth of the maxilla, but also act on the front of the impedance center of the maxilla, the vertical upward component of force can be used to inhibit the height growth of the front end of the maxilla, thereby changing the growth direction of the maxilla and changing the occlusal plane. The high-position extraoral bow combined with the muscle activator can also change the growth direction of the mandible at the same time, bringing about the treatment result of counterclockwise rotation of the mandible, thereby changing the position of the mandible and the face shape. However, when the high-position traction type dental correction device is actually used, when fine-tuning the extraoral bow through the elastic part and the telescopic joint, the operator needs to use both hands to operate, with one hand holding the double-threaded long nut or the single-threaded long nut, and the other hand holding the long screw or telescopic sleeve, so that the two rotate relative to each other, and then fine-tune the operation. The operation is relatively cumbersome, so it needs to be improved. Utility Model Content

[0024] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0025] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0026] Combine Figure 1-Figure 5As shown, in this embodiment, a silicone bite inducer with an extraoral bow includes a bite inducer body 280 and an extraoral bow 120 relatively arranged on the outside of the bite inducer body 280, and also includes a head cap 100. Both ends of the head cap 100 are connected to the corresponding extraoral bow 120 through an adjustment component 110. The adjustment component 110 includes a mounting box 200 arranged at both ends of the head cap 100. One end of the mounting box 200 is connected to a limiting belt 240. A plurality of card holes 260 are evenly provided on the limiting belt 240. The extraoral bow 120 is clipped into the corresponding card holes 260. A fine-tuning component for fine-tuning the bite inducer body 280 is also provided in the mounting box 200.

[0027] The occlusal guide in this embodiment is used to perform traction correction on the maxilla; wherein, the occlusal guide body 280 is of an existing structure and is made of silicone material. The occlusal guide body 280 is occluded on the maxilla of the oral cavity, and the head cap 100 is worn on the head so that the outermost end of the extraoral bow 120 is clamped into the corresponding limiting band 240, so that the head cap 100 pulls the extraoral bow 120, so that the extraoral bow 120 pulls the occlusal guide body 280 to be close to the maxilla, thereby achieving traction correction on the maxilla;

[0028] The head cap 100 includes two elastic bands, which are at a certain angle to each other, and the corresponding ends of the two elastic bands are connected to each other by sewing, thereby forming the head cap 100;

[0029] The adjustment assembly 110 is fixedly mounted at the connection position of the corresponding ends of the two elastic bands. The outermost end of the extraoral bow 120 is hook-shaped, and there is a certain angle between it and the occlusal inducer body 280. When the head cap 100 is worn on the back of the patient's head, the outermost end of the hook-shaped extraoral bow 120 can be snapped into the snap hole 260 on the limiting band 240, so that the extraoral bow 120 is pulled along its extension direction. This traction can better make the occlusal inducer body 280 fit the upper jaw and correct it.

[0030] The plurality of clamping holes 260 are provided on the limiting belt 240 so that the extraoral bow 120 can be clamped into the clamping holes 260 at different positions, thereby making the occlusal inducer adaptable to different patients and having better applicability.

[0031] The limiting strip 240 and the mounting box 200 are both made of hard plastic, which makes them light and strong enough to facilitate the clamping installation of the extraoral bow 120 on the limiting strip 240 and the assembly of the fine-tuning assembly in the mounting box 200.

[0032] In actual use, after the bite guide has corrected the maxilla for a period of time, the maxilla is corrected. At this time, the traction force exerted on the extraoral bow 120 cannot make the bite guide body 280 close to the maxilla for traction correction. Therefore, it is necessary to fine-tune the traction force exerted on the extraoral bow 120 to ensure that the bite guide continues to traction correct the maxilla.

[0033] In this embodiment, through the setting of the fine-tuning component, it is possible to drive the limiting belt 240 to shrink and move in the installation box 200 along the extension direction of the extraoral bow 120, so that the extraoral bow 120 can continue to pull the occlusal inducer body 280 to be close to the mandible, so that its correction effect is better; wherein, through the setting of the fine-tuning component, the operator can operate with one hand to realize the shrinkage and movement of the limiting belt 240 in the installation box 200, and the operation is simple and convenient.

[0034] Combine Figures 1-4 As shown, in this embodiment, a mounting cavity 310 is provided in the mounting box 200, and the fine-tuning assembly includes a threaded rod 220 provided in the mounting cavity 310, one end of the threaded rod 220 extends out of the mounting cavity 310, and one end of the limiting belt 240 is connected to the protruding end of the threaded rod 220 through the connecting block 230, and a rotatable main bevel gear 350 is provided in the mounting cavity 310, and the threaded rod 220 is threaded through the main bevel gear 350. A secondary bevel gear 360 that cooperates with the main bevel gear 350 is also provided in the mounting cavity 310, and the rotation of the secondary bevel gear 360 is used to drive the main bevel gear 350 to rotate to realize the movement of the threaded rod 220 in the mounting cavity 310.

[0035] In actual use, the installation cavity 310 is provided with an opening on one side for installing the fine-tuning assembly in the installation cavity 310. A side plate 290 is provided at the opening of the installation cavity 310. The side plate 290 is fixed to the opening of the installation cavity 310 by screws.

[0036] The mounting box 200 is disposed at the end of the head cap 100 along the extending direction of the extraoral bow 120. Meanwhile, the threaded rod 220 is disposed within the mounting cavity 310 along the extending direction of the extraoral bow 120. Thus, when the head cap 100 is worn on the head, the extraoral bow 120 can be preferably pulled along the extending direction of the extraoral bow 120.

[0037] The cam 320 is fixed to the workbench 310 so that the cam 320 can be fixed to the workbench 310 to prevent the cam 320 from rotating.

[0038] The secondary bevel gear 360 is rotatably mounted in the mounting cavity 310, so that when the secondary bevel gear 360 drives the primary bevel gear 350 to rotate, the threaded rod 220 can move in the mounting cavity 310 along the extension direction of the mounting cavity 310 due to the limitation of the limiting member, thereby enabling the threaded rod 220 to drive the connecting block 230 to move in the mounting cavity 310, so that the connecting block 230 can drive the limiting belt 240 to move, so that the limiting belt 240 can pull the extraoral arch 120 to fine-tune the occlusal inducer body 280, so that the occlusal inducer body 280 can better fit the upper jaw;

[0039] In order to prevent the threaded rod 220 from being separated from the mounting box 200 when moving in the mounting cavity 310, a retaining ring 370 is provided on the threaded rod 220 to prevent the threaded rod 220 from being separated from the mounting box 200.

[0040] In actual use, a limiting groove 330 is provided on the outer side surface of the threaded rod 220 along its axial direction. The limiting member includes a limiting ring 340 sleeved on the outside of the threaded rod 220. The limiting ring 340 is fixed to the side wall of the installation cavity 310. A limiting block is provided on the inner side wall of the limiting ring 340. The limiting block extends into the limiting groove 330 to realize the circumferential limitation of the threaded rod 220 by the limiting ring 340.

[0041] In actual use, the connecting block 230 is provided with a mounting groove 300 for one end of the limiting belt 240 to be inserted into, and the connecting block 230 is provided with a pin that passes through the limiting belt 240, thereby realizing the installation of the limiting belt 240 on the threaded rod 220.

[0042] In this embodiment, a cavity is provided on the side wall of the installation cavity 310, and a rotating shaft 400 is provided in the cavity. One end of the rotating shaft 400 is connected to the secondary bevel gear 360, and the other end extends out of the installation box 200. A knob 210 is fixed to the protruding end of the rotating shaft 400, and the rotating knob 210 is used to realize the rotation of the secondary bevel gear 360.

[0043] Among them, by setting the knob 210 outside the installation box 200, the operator can rotate the knob 210 with one hand outside the installation box 200, thereby realizing the contraction and movement of the limiting belt 240 in the installation box 200, which is simple and convenient to operate;

[0044] Among them, one end surface of the secondary bevel gear 360 is in contact with the side wall of the installation cavity 310, and one end surface of the knob 210 is in contact with the lower side surface of the installation box 200, so that the secondary bevel gear 360 will not move up and down in the installation cavity 310, ensuring that it cooperates with the main bevel gear 350;

[0045] The cavity is adapted to the rotating shaft 400 so that the gap between the cavity and the rotating shaft 400 is small, so that the rotating shaft 400 does not wobble in the cavity, and further the secondary bevel gear 360 does not wobble in the mounting cavity 310, so that the secondary bevel gear 360 can better engage with the main bevel gear 350.

[0046] Working principle: bite the occlusal inducer body 280 on the upper jaw of the oral cavity, wear the head cap 100 on the head, and insert the outermost end of the extraoral bow 120 into the corresponding card hole 260, so that the head cap 100 pulls the extraoral bow 120, so that the extraoral bow 120 pulls the occlusal inducer body 280 to be close to the upper jaw, so as to realize the traction correction of the upper jaw. After the occlusal inducer corrects the upper jaw for a cycle, the upper jaw is corrected. At this time, the traction force exerted on the extraoral bow 120 cannot make the occlusal inducer body 280 close to the upper jaw for traction correction. When it is necessary to fine-tune the traction force exerted on the extraoral bow 120, turn the knob 210 to rotate the rotating shaft 400. The driving secondary bevel gear 360 drives the main bevel gear 350 to rotate on the threaded rod 220. Through the setting of the limit plate 320, the main bevel gear 350 will not move on the threaded rod 220. Through the setting of the limit member, the threaded rod 220 will not rotate circumferentially, so that the threaded rod 220 can move in the installation cavity 310, so that the threaded rod 220 can drive the connecting block 230 to drive the limiting belt 240 to move in the installation cavity 310, so that the limiting belt 240 can pull the extraoral bow 120 to fine-tune the occlusal inducer body 280, so that the occlusal inducer body 280 can continue to fit the upper jaw, ensuring that the occlusal inducer continues to pull and correct the upper jaw.

[0047] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
