[0030] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as they do not conflict with each other.

[0031] The utility model provides Figures 1 to 3 As shown in , a locking pin type tongue grid brace is intended to solve the disadvantage that the base 100 and the tongue grid 200 in the existing tongue grid brace are not removable.

[0032] The present locking pin type tongue-grid appliance mainly comprises: a base 100 and a tongue-grid 200, wherein the base 100 comprises a base body 110 and a first clamping part 120, wherein the base body 110 is used to be fixed on the upper jaw of the patient, and the first clamping part 120 is embedded and arranged on the surface of the base body 110 away from the upper jaw. Specifically, the base body 110 matches the upper jaw of the patient, and the base body 110 can be fixed on the upper jaw of the patient. The tongue-grid 200 comprises a stop wire part 220 and a second clamping part 210, wherein the second clamping part 210 is used to be detachably connected with the first clamping part 120, wherein one end of the stop wire part 220 is away from the upper jaw, and the other end is connected with the second clamping part 210, and the stop wire part 220 is detachably arranged on the base body 110 through the first clamping part 120 and the second clamping part 210, and the patient can only remove the tongue-grid 200 when eating, which does not affect eating, and can also continue to play the therapeutic role of other components of the appliance. The locking pin type tongue grid appliance can also be used in conjunction with other orthodontic devices such as tongue springs and lip stops, further broadening its application range and meeting the needs of doctors and patients.

[0033] During actual use, the patient can install the tongue guard 200 on the base 100, and then place the two ends of the base 100 at the corresponding positions in the patient's mouth and wear it until the entire base 100 is completely fixed in the patient's mouth; when eating, the base 100 can be removed from the mouth first, and then the tongue guard can be removed from the base 100, and only the base 100 can be worn in the mouth.

[0034] The base 100 and tongue grid 200 in the traditional tongue grid 200 appliance are usually designed to be non-detachable to ensure the stability of the appliance during wearing. However, due to the fixed connection between the tongue grid 200 and the base 100, the tongue grid 200 fixed on the base 100 will occupy the space in the oral cavity, and the chewing and swallowing of food by the patient will be greatly affected when wearing the appliance to eat. However, if it is completely removed to eat, it will affect the function of other components on the appliance. In addition, patients wearing fixed tongue grid 200 appliances may also encounter problems such as difficulty in pronunciation and inconvenience in oral hygiene maintenance. The detachable tongue grid 200 in the locking pin tongue grid 200 appliance can avoid such discomfort, improve the patient's willingness and compliance to wear the appliance, and improve the success rate of the correction plan.

[0035] The utility model provides a first clamping portion 120 and a second clamping portion 210, and the tongue grid 200 is detachably arranged on the base 100 through the first clamping portion 120 and the second clamping portion 210. The patient can only remove the tongue grid 200 when eating, which does not affect eating and can continue to play the therapeutic effects of other components of the orthodontic appliance; the tongue grid 200 can also be removed when brushing teeth, which is convenient for the maintenance of the orthodontic appliance, reduces the inconvenience of use for patients, improves their willingness and compliance to wear the orthodontic appliance, and improves the success rate of the correction plan.

[0036] In some embodiments, Figure 1 to Figure 2 As shown in , the first clamping portion 120 includes: a clamping groove 121, and the clamping groove 121 is arranged on the surface of the base body 110 away from the upper jaw;

[0037] A limit block 122, which is disposed in the slot 121, and a limit area 123 is formed between the limit block 122 and the bottom of the slot 121;

[0038] The shape of the second clamping portion 210 matches the limiting area 123 .

[0039] In some embodiments, Figure 1 to Figure 2 As shown in , the second clamping portion 210 includes: a fixing block 211, and the wire blocking portion 220 is arranged on the fixing block 211;

[0040] The card block 212 is arranged on the fixed block 211, and the card block 212 matches the limiting area 123. Specifically, the card block 212 or the fixed block 211 can be made of an elastic material, and when the card block 212 is squeezed, it can move toward the fixed block 211. When the fixed block 211 is inserted into the card slot 121, the surface of the card block 212 away from the fixed block 211 can be squeezed by the limiting block 122 and move toward the fixed block 211, so that the second clamping portion 210 can be inserted into the card slot 121. When the second clamping portion 210 reaches a predetermined position in the card slot 121, the surface of the card block 212 away from the fixed block 211 is not squeezed by the limiting block 122, and the card block 212 moves toward the side wall of the card slot 121. At this time, the card block 212 reaches the limiting area 123 for fixation.

[0041] In some embodiments, Figures 1 to 3 As shown in , the wire blocking part 220 includes: a plurality of wire blocking bodies, the shape of the wire blocking body is U-shaped, the upper end of the wire blocking body is connected to the fixing block 211, and the lower end of the wire blocking body is away from the upper jaw, which can block the tongue in the oral cavity.

[0042] In some embodiments, Figure 1 As shown in , the fixed block 211 includes: two movable parts 211a, a plurality of wire blocking bodies are respectively arranged on the two movable parts 211a, and two clamping blocks 212 are respectively arranged on the two movable parts 211a;

[0043] The elastic part 211b is disposed between the two movable parts 211a, and the elastic part 211b and the base 100 are both penetrated by a coaxial insertion hole 211d;

[0044] The latch portion 211c matches the insertion hole 211d, and the latch portion 211c is detachably disposed in the insertion hole 211d.

[0045] Specifically, the latch portion 211c is slidably disposed on the base 100 (eg Figure 2 As shown in FIG. 2 , the latch portion 211 c can be close to or away from the insertion hole 211 d. By controlling the position of the latch portion 211 c, the tongue grille 200 and the base 100 can be fixed to or separated from each other.

[0046] In actual use, the latch portion 211c can be inserted into the insertion hole 211d to reduce the deformation of the elastic portion 211b, and the surface of the block 212 away from the fixed block 211 is difficult to move toward the movable portion 211a, and the tongue fence 200 is difficult to remove from the base 100. When the tongue fence 200 needs to be removed from the base 100, the wire blocking body can be pressed by hand to make the plurality of wire blocking bodies arranged on the two movable portions 211a approach each other, and the plurality of wire blocking bodies drive the two movable portions 211a to approach each other. At this time, the surface of the block 212 away from the fixed block 211 can move toward the movable portion 211a, and the tongue fence 200 can be removed from the base 100.

[0047] In some embodiments, Figure 1 As shown, the width of the elastic part 211b gradually increases away from the wire blocking body. Specifically, the plurality of wire blocking bodies arranged on the two movable parts 211a can be opened outwards. Since the width of the elastic part 211b toward the wire blocking body is smaller, and the width of the elastic part 211b away from the wire blocking body is larger, the compression distance of the part of the elastic part 211b toward the wire blocking body is smaller than the compression distance of the part of the elastic part 211b away from the wire blocking body. At this time, the two movable parts 211a are both away from the rotation of the wire blocking body, and the distance between the two movable parts 211a is reduced. The surface of the clamping block 212 away from the fixed block 211 can move toward the direction of the movable part 211a, and the tongue grille 200 can be removed from the base 100.

[0048] In some embodiments, Figure 1 to Figure 2 As shown in FIG. 1 , the shape of the insertion hole 211 d is a trapezoid or a triangle, and the width of the insertion hole 211 d gradually increases away from the wire stop body.

[0049] In some embodiments, Figure 1 to Figure 2 As shown in FIG. 1 , the limiting block 122 is in an arc shape, the clamping block 212 is in an arc shape, and the clamping block 212 is sleeved and fixed on the fixing block 211 to form an arrow shape.
